海外TECH	DEV Community	A Playbook to Properly Implement Pay As You Go Pricing	https://dev.to/moesif/a-playbook-to-properly-implement-pay-as-you-go-pricing-k9g	A Playbook to Properly Implement Pay As You Go PricingUsage based pricing consumption based pricing and PAYG Pay As You Go are relatively new SaaS pricing models that enable you to drive both top of line growth while also increasing net revenue retention over more traditional subscription pricing models such as license or seat based pricing With Pay As You Go a customer only needs to pay for what they consume such as hours of a VM or number of messages sent APIs naturally are transaction based which make them suitable for new consumption based pricing In fact all three cloud providers AWS Google and Azure leverage consumption based billing so their customers can optimize their infrastructure Prepaid vs postpaid billingFirst you ll want to decide whether you want prepaid or a postpaid billing Prepaid billing requires the customer to purchase credits or pre negotiated quota ahead of time creating a positive balance that is then burned down If they are credits a customer will need to periodically top off their account by purchasing additional credits before they run out Some systems enable automatic top off once a balance falls below a defined threshold This can improve your business cash flow since you re able to leverage the spent capital even before any costs are incurred to deliver their service Irrespective of Pay As You Go most enterprise companies require enterprise contracts to be prepaid for the term as prepaid enables more payment options such as a bank wire or ACH Customers also benefit since they can set hard budgets for your service and disable any auto top off functionality The downside to prepaid billing is the additional friction added when purchasing a plan when usage is not predictable especially if it s not a bundled amount Prepaid billing requires the customer to estimate how much to purchase even before even using the service which can also cause more refund requests if they don t end up using the credits Unless a card is on file collecting additional fees due to overage or term violations may be harder Customers may be opposed to prepaid billing since the capital is tied up This can be especially true for growth oriented spend such as pay per click advertising or credit card processing In these cases a customer may be willing to pay a higher price since they already collected the revenue from their users A third option is to leverage a hybrid of both For example a bundled amount could be prepaid on a credit card but then overage fees are post paid Billing frequencyYou will also need to decide how often a customer is billed which is related to whether you leverage prepay vs postpay billing One option is to invoice periodically such as the nth day of the month This makes it easier on your customers billing department as your service more predictable while minimizing extra work to pay invoices This is also easier to understand as most SaaS subscriptions are already billed annually or monthly It s not recommended to have a common billing day for all customers like the start or end of a month as this can cause your support team to deal with a flood of billing requests on that day notice info A second option is threshold based If prepaid billing a customer needs to purchase credits which in turn needs to be topped off once the balance drops below a threshold Many systems allow this to charge a card automatically such as When the balance drops below add worth of credits If you implement postpaid billing the threshold is simply the reverse in that when the negative balance goes above a threshold such as an invoice is generated and credit card charged This is increasingly common in self serve advertising The downside is a lack of predictability since some months could have many more charges than other months If not careful this can generate an unnecessary number of invoices with small charges Similarly this can cause a nightmare for your accounting team and harder to predict future revenue Billing measurementBased on your billing time and frequency you will need to implement a system that can accurately measure and report on transaction volume for each customer account This usually means having an analytics system on API calls or transactions Because each customer may have a different billing period your analytics solution should have a way to handle this If you leverage periodic billing then you can query a customer s usage when you invoice them which is usually on a predefined billing day For threshold billing measurement may be a little more tricky since an invoice can be generated at any time not just on the customer s billing day This means you need to keep track and trigger invoices once the threshold is reached Leveraging a ready made API analytics tool like Moesif can reduce your development and maintenance time drastically vs a custom in house billing Quota emailsWhen it comes to pricing customers don t want surprises Yet with consumption based billing invoice amounts can vary depending on their usage By sending automated quota and usage emails your customers can stay informed when their cost increases or they approach a quota limit If you leverage a hybrid model such as a bundled fee and an overage fee you may want to remind customers once they used the majority of their quota or when they exceeded it A behavioral email platform like Moesif can be configured to silence notifications for a period like days one a customer gets alerted to avoid spamming your customer s inboxes Then after days if a customer is still exceeding the limits you can send a second email Self serve billing dashboardsBecause you are billing based on usage it s imperative to provide your customers with visibility into these usage and success metrics in a self serve way Rather than force your customers to ask for support just to understand how much quota they used you can embed metrics right inside your developer portal with a tool like Moesif s embedded charts Your customers will want to slice and dice this data so that they can understand where their usage is going and where they can save money Requirements for usage reports include Ability to see usage by different intervals like hourly daily or monthly Shows number of business transactions even if your API can handle requests in batchA way to break usage down by user demographics or clients Beyond usage reports you can also embed other metrics like SLA API logs and more to improve your developer experience and reduce barriers to adopting your API platform ConclusionPay As You Go pricing can drive both revenue and retention for your business with implemented properly Yet consumption based billing is also more challenging to implement than more traditional subscription pricing You need accurate measurement of usage and also workflows to ensure your customers are not surprised once they receive an invoice Tools like embedded charts and quota emails can go a long ways to keeping your customers informed Do you want to know how customers use your APIs Try Moesif API Analytics This article was originally written for the Moesif blog by Derric Gilling CEO and founder of Moesif API Analytics	2022-06-06

monitoring with open source tools OpenTelemetry and SigNoz Kubernetes monitoring is a critical process for keeping your Kubernetes clusters running in fine health In this tutorial we will learn everything about Kubernetes monitoring We will be using two open source tools OpenTelemetry and SigNoz to monitor a Kubernetes cluster so you can follow along with the tutorial easily Containerization technologies like Docker and Kubernetes have solved many engineering problems like on demand scaling and deploying new applications but it also brings a lot of operational complexity Modern distributed applications deployed using Kubernetes have too many moving parts and cluster operators need a monitoring tool to run their clusters effectively In this tutorial we will be using open source tools OpenTelemetry and SigNoz to monitor a Kubernetes cluster With open source tools you are more in control of your data Furthermore if there are privacy laws you can deploy the tools on prem so that there is no need to send the data to any cloud vendor Why monitor your Kubernetes cluster Kubernetes makes it easy to deploy and operate applications in a microservice architecture However as the number of microservices increases your Kubernetes cluster also becomes quite complex to manage Cluster operators need to take care of a lot of things like running the desired number of pods utilization of cluster resources and misconfigurations Monitoring tools can help cluster operators proactively manage their clusters by reporting on critical metrics But traditional monitoring tools are often inadequate to monitor the dynamic environment of a Kubernetes cluster Modern monitoring tools should enable engineering teams to set up an observability framework for their infrastructure including Kubernetes clusters Observability is a term from control theory which states that a system is observable if the internal states of the system can be determined by examining its output For observability in computing systems these output signals are commonly divided into three major categories logs metrics and traces OpenTelemetry is an instrumentation layer for cloud native applications that aims to generate and collect these output signals Before we deep dive into the tutorial for Kubernetes monitoring let s have a brief overview of OpenTelemetry and SigNoz What is OpenTelemetry OpenTelemetry also known as OTel for short is an open source vendor agnostic set of tools APIs and SDKs used to instrument applications to create and manage telemetry data metrics traces and logs It is backed by Cloud Native Computing Foundation the same foundation under which Kubernetes graduated OpenTelemetry aims to make telemetry data a built in feature of cloud native software applications The telemetry data is then sent to a backend analysis tool for storage and visualization OpenTelemetry can be used to generate metrics from Kubernetes clusters OpenTelemetry is the bedrock for setting up an observability framework It is backed by a huge community and it is quietly becoming the world standard for instrumentation of cloud native applications It also provides you the freedom to choose a backend analysis tool of your choice And that s where SigNoz comes into the picture OpenTelemetry and SigNozIn this article we will use SigNoz a full stack open source application monitoring and observability platform that can be used for storing and visualizing the telemetry data collected with OpenTelemetry It is built natively on OpenTelemetry and works on the various data formats OTLP Zipkin Jaeger Prometheus backends etc SigNoz provides query and visualization capabilities for the end user and comes with out of box charts for application metrics and traces OpenTelemetry and SigNoz can help you monitor important metrics from your Kubernetes cluster What should I monitor in Kubernetes Monitoring your Kubernetes cluster effectively is necessary to keep your containerized infrastructure running properly The first step is to decide which metrics to monitor for your Kubernetes cluster The important components that need to be monitored in a Kubernetes cluster include Node level metricsPod level metricsContainer level metricsWith OpenTelemetry and SigNoz you can collect and visualize these metrics easily Now let s get down to some action and see everything for yourself We will divide the tutorial into two parts Installing SigNozKubernetes Infrastructure Monitoring Installing SigNozFirst you need to install SigNoz so that OpenTelemetry can send the collected data to it SigNoz can be installed on Kubernetes easily using Helm helm repo add signoz kubectl create ns platformhelm namespace platform install my release signoz signozYou should see similar output NAME my releaseLAST DEPLOYED Mon May NAMESPACE platformSTATUS deployedREVISION NOTES You have just deployed SigNoz cluster frontend version query service version alertmanager version otel collector version otel collector metrics version For detailed instructions to set up SigNoz cluster in Kubernetes please refer to our documentation To port forward SigNoz UI on your local machine run the following kubectl port forward n platform service my release signoz frontend When you are done installing SigNoz you can access the UI at http localhost You can alternatively set the SigNoz Frontend service type as LoadBalancer NodePort or use Ingress for the custom domain Now that you have SigNoz up and running it s time to set up OpenTelemetry Collectors for your Kubernetes cluster OpenTelemetry Collector is a component of OpenTelemetry that helps to collect process and export the telemetry data You can enable sampling and export data in multiple formats using OpenTelemetry collectors Kubernetes Infrastructure monitoringOpenTelemetry uses receivers to collect data in specified formats A receiver is how data gets into the OpenTelemetry Collector Generally a receiver accepts data in a specified format and translates it into the internal format to be consumed by OpenTelemetry We will use the following receivers of the OpenTelemetry collector to collect metrics from the Kubernetes cluster kubeletstats Kubelet Stats Receiver pulls pod metrics from the API server on a kubelethostmetrics Host Metrics receiver generates metrics about the host system Steps to export Kubernetes metrics to SigNozStep Clone Otel collector repogit clone amp amp cd otel collector ksStep Set up the address to SigNoz in your OTel collectorsYou need to set up the address to SigNoz in your OTel collector which is collecting the ks metrics If you are running SigNoz in an independent Kubernetes cluster or VM you need to change the placeholder IPs in the following files with the IP of machine where you are hosting SigNoz agent infra metrics yamldeployment all in one yamlYou need to update the below section exporters otlp endpoint lt SigNoz Otel Collector Address gt tls insecure trueIf you are running SigNoz in the same Kubernetes cluster where your applications are you have to replace the above endpoint in agent infra metrics yaml and deployment all in one yaml bymy release signoz otel collector platform svc cluster local In the above code snippet my release is the Helm release nameplatform is the namespace where SigNoz is deployedIn case of SigNoz installed in different kubernetes cluster machine update it to the appropriate address Step Install OTel collectors and enable specific receivers to send metrics to SigNozTo access metrics from kubeletstats receivers you have to kubectl create ns signoz infra metricskubectl n signoz infra metrics apply Rf agentkubectl n signoz infra metrics apply Rf deploymentThe output will be something like this namespace signoz infra

be something like this NAME READY STATUS RESTARTS AGEotel collector agent kkchn Running motelcontribcol dcc tkk Running mTo check logs of the OTel collector agent export POD NAME kubectl n signoz infra metrics get pods l component otel collector agent o jsonpath items metadata name kubectl n signoz infra metrics logs POD NAMEOutput should look like this T Z info service telemetry go Setting up own telemetry T Z info service telemetry go Serving Prometheus metrics address level basic service instance id c c e c dcbdf service version latest T Z info service collector go Starting otelcol contrib Version NumCPU T Z info service collector go Everything is ready Begin running and processing data In case of any errors in the above logs you should not see except for the case of SigNoz being unavailable or inaccessible Step Plot Metrics in SigNoz UIIf the previous step was a success you should be able to plot graphs from the list of kubelet metrics follow these instructions to create dashboards and widgets Monitor Kubelet Metrics with SigNozYou can get started easily for monitoring Kubelet metrics with SigNoz All you have to do is to import a JSON file and you will get out of box charts for your Kubelet metrics Under the Dashboards tab of SigNoz click on New Dashboard and then Import JSON Import a JSON file to get started with monitoring your Kubelet metricsThe Kubelet metrics dashboard will give you stats about CPU and memory metrics of the Kubernetes cluster Monitor Kubelet metrics with SigNozYou can include more widgets using other metrics to the dashboard as per your requirements Monitor Node Metrics of your Kubernetes clusterNode metrics are very important as we have nodes underneath the abstraction of Kubernetes container orchestration Similar to the previous section we will be importing JSON files to create dashboards of our node metrics We will be using the hostmetrics receiver of OTel collector to build these dashboards There are many nodes in a Kubernetes cluster Hence we will be creating multiple dashboards for each node SigNoz will add support for label widgets in the future which would make it possible to monitor all nodes using a single dashboard Let s run the following commands to generate hostmetrics dashboard JSON files for each node automatically for node in kubectl get nodes o name sed e s node do curl sL HOSTNAME node DASHBOARD TITLE HostMetrics Dashboard for node bashdoneAfter importing the generated dashboard JSON you should be able to see the dashboard for your node metrics Node metrics monitoring with SigNoz ConclusionUsing OpenTelemetry and SigNoz you can set up a robust monitoring framework for your Kubernetes cluster OpenTelemetry is the future for setting up observability for cloud native apps It is backed by a huge community and covers a wide variety of technology and frameworks Using OpenTelemetry engineering teams can easily monitor their infrastructure and application instrument polyglot and distributed applications with peace of mind You can then use SigNoz to store and visualize your telemetry data SigNoz is an open source observability tool that comes with a SaaS like experience You can try out SigNoz by visiting its GitHub repo If you have any questions or need any help in setting things up join our slack community and ping us in the  support channel Further ReadingSigNoz an

海外TECH	DEV Community	What I learned about writing and workflow during the pandemic	https://dev.to/wesen/what-i-learned-about-writing-and-workflow-during-the-pandemic-4mi5	What I learned about writing and workflow during the pandemicOver the last years I have been working at getting better at writing and communication I started using the gorgeous Bear application on my iPad Using beautiful tools has always inspired me so much so that I will often go for looks over functionality Bear is not only gorgeous it also comes with a big bag of features markdown tags wiki style linking apple watch app beautiful exports automatic syncing As I was getting to know Bear I experimented with different kinds of writing Having found a productive workflow as a musician over the pandemic I tried to apply the concepts that worked for me in the studio to my new endeavor Daily processThe most important part of being productive making music was to sit down and do some work everyday even if just for one hour Over time the consistent work accrues and you reap seemingly enormous benefits while never really having felt the need for inspiration to strike or having to do long grueling sessions The advantage of doing consistent short sessions is that it never feels bad to stop when things get frustrating you did your work for the day tomorrow will bring new joy I divided this creative workflow in roughly four big activities Collecting and janitorial workThe first area is what I call process the janitorial part It is learning new techniques searching for samples recording field recordings making patch collections preset sounds sorting files wiring things up with cables installing software updates This is stuff that you absolutely don t want to do when in the middle of a more creative session as it is a sure way to bring you out of the flow For writing it means note taking gathering reference material picking up and jotting down random ideas collecting quotes I started taking notes for articles I came across the internet making little entries for topics I knew things about all loosely connected through wiki links While researching Bear and note taking I came across Andy Matuschak s work and the ide aof keeping a Zettelkasten to which I will come back to in a future post I started keeping smaller atomic notes and cross linking them I used tags to keep my notes organized I ultimately migrated from Bear to Obsidian for managing my notes more about this in a future article and you can see a public part of my vault at mnml s vault Creating raw materialThe next activity is creating raw material Musically this would be coming up with beats song ideas recording synth progressions It is not about making a song it is about having fun making music in a very restricted context In fact the more restrictions are placed on the activity the easier it is to get started A prompt would for example be make beats with this one set of drum sounds Often a seemingly banal restriction would spark inspiration and I would go on for hours Freeform writingCreating raw written material means finding ways to deal with the fear of the blank page In order to turn off the internal critic I practiced writing in a stream of consciousness style without worries about the outcome I wrote free form about software architecture about bugs I was encountering about project planning ideas Over time getting into the writing zone became effortless The times I start feeling paralyzed I usually am anxious about the final form of what I am trying to write Keep a collection of promptsI keep a long list of prompts for example Blog ideas for blog articles for different areas I have a long list of prompts for work related topics different technologies that could be interesting marketing ideas broader thoughts about product and workflow links to articles I found interesting If I feel stuck or can t seem to find a way to create a seedling I will choose a prompt in one of my ideas documents and try to write down a stream of consciousness about it Using daily notesIn order to separate writing from an outcome I do most of my writing in a daily note It is completely free form and I will often paste images drawings website captures conversations along with longer segments of writing I keep it messy for a reason purposely not try to make things tidy or think about a potential reader Copy pasting chat threadsInterestingly another technique for creating raw material that works for me is just copy pasting the long ramblings I post on various chat apps and social media pages It is a variant of the rubberduck technique in that here thinking about a reader actually stimulates creativity I need to feel like I am having a conversation in order to refine my ideas I would often paste slack screenshots or twitter threads into my notes Taking notes on the goFinally the apple watch of Bear app was invaluable I usually have a lot of ideas while riding my bike or running and with the watch I could easily record these straight into my daily note The speech recognition was always a bit of a mess and I learnt over time to take much longer notes than I thought would be necessary at the time Nothing worse than coming back to a note that says bathroom architecture tomato pixie and have no idea what that was supposed to mean Properly file the created material An absolutely vital part of creating raw material is to make that raw material easy to reuse in the future This means naming files correctly filing them in ways where they can be found later on adding proper metadata saving related resources nearby This is more important for music than for writing but even for writing I make sure to cleanly label my files link them in a way that makes it easy to recall them link additional documents such as project files for graphics and diagrams correctly quote referenced material I put everything on dropbox so that I can access it quickly from wherever I am even on other people s computers It also makes it easy to share work in progress if I feel like collaborating AssemblingIn the studio the next part of the process is finding different musical ideas and sounds and making them work together This is when songs start to appear The key here is to have quick recall of all the raw material created in the previous step This is where the janitorial work comes from If everything is nicely labeled well sorted backed up documented it becomes very easy to stay in the flow while assembling Having a lot of raw material also helps A fascinating thing is that musically the best ideas often come from the least inspired sessions If I was feeling very inspired and excited making beats or certain synthesizer sounds this usually meant that after a night of sleep the result sounded horribly cliche Sessions where I really had to labor to come up with something interesting provided much richer material in the long run Assembling writingI feel that writing is similar although I have much less experience in that domain Notes and raw writings need to be easily retrievable They also need to age This means that the value of an idea or a piece of writing becomes more apparent over time If something is still interesting after months or you can find it expressed in different ways in multiple notes it probably touches upon some deeper meaning Both musically and in writing I think of assembling as working with scissors and glue It is not creating as much as it is just moving things left and right and trying out different juxtapositions This is where using digital media helps tremendously Copy paste duplicate erase undo redo save copies All these things are tremendously tedious with real tape or pen and paper Furthermore using tags and wiki links and the search functionality in Bear app I could quickly retrieve my notes and turn them into bigger documents This easy recall of previous notes and references gave my writing a new depth EditingThe final part of the process is editing After heated creation and assembling a fair amount of semi finished ideas have accumulated They are raw songs or articles unfinished but roughly of the right length or longer with the main idea clearly present At this point I choose one or two of the best ideas present and I set down to work to actually finishing them This is almost mechanical work It is about editing sentences shortening paragraphs looking up references reading for flow In music it is cleaning up recordings adding missing elements mixing the sounds spatially making sure the flow and structure is correct The work is technical and requires an alert mind but it doesn t rely on inspiration You can just turn on the computer and do it a bit like doing the dishes Interestingly for outsiders this is where the magic happens It seems that all the rubbish writing the wonky sounds and ideas suddenly fall into place and turn into something magical sometimes within minutes But really the magic is in the workflow It is present in labeling notes in collecting web links in writing free flowing rubbish in assembling individual paragraphs The editing pass is akin to putting a beautiful cake into the oven and then waiting You know it will come out great if you are just careful enough to take it out at the right time Quantity over QualityIn both creating raw material and in assembling I always try to go for quantity over quality The quality of the output is not directly related to the quality of what the work that gets done at each step The quality of the output is only determined by the selection that gets done before editing and by the experience and ruthlessness of the editing itself I would say that for my music around of the material I create ultimately gets released But the are what made that worth releasing What are your techniques for writing What about you Do you have a workflow for writing Did the pandemic help you become a better writer What do you think you
