海外TECH	DEV Community	A Complete Guide to Distributed Tracing	https://dev.to/signoz/a-complete-guide-to-distributed-tracing-32j1	A Complete Guide to Distributed TracingDistributed tracing helps you track requests across services and understand issues affecting your application performance In distributed cloud architecture debugging performance issues is complicated Distributed tracing gives visibility to teams on how a user request performs across different services protocols and cloud infrastructure Let s start with a brief overview of distributed tracing What is Distributed Tracing Distributed tracing is a method to track user requests in their entirety as it travels across components of a distributed system Cloud and containerization technologies have enabled the creation of distributed system designs like microservices and FaaS functions as a service Distributed tracing enables you to connect the dots of how your distributed system interacts While traditional monitoring struggles to illuminate the behavior of distributed systems distributed tracing can help you identify performance patterns of the various components in a distributed system In a distributed system a click from a user initiates a transaction that can travel through hundreds of components before completing the user request Distributed tracing is the technique that shows how the different components interact together to complete the user request The top two important data points that distributed tracing captures about a user request are the time taken to traverse each component in a distributed systemthe sequential flow of the request from its start to the end Why is Distributed Tracing needed In the modern digital ecosystem a user s expectation of what s possible digitally has no limits It gave rise to the need for rapid innovation and on demand scaling Modern application architecture using cloud native containerization and microservices is a very complex distributed system The microservices architecture allows multiple technology stacks decentralized data management and independent evolution of services in an application This leads to an ever increasing number of components in an application s architecture The benefits of microservices architecture come with the increased complexity of operation and troubleshooting A user request can travel hundreds or even thousands of these components to fulfill a single use case As such there are many failure points in the application and robust monitoring is needed to identify failure points and latency issues But traditional monitoring tools are not adequate to monitor microservices architectures This is because these tools were designed to monitor a single application instance The metrics collected from a single instance will not give us insights into how a user request performed as it touches multiple components but the data collected with distributed tracing can give us those insights Understanding a TraceA trace in distributed tracing represents an end to end user request and is composed of single or multiple spans Spans are fundamental building blocks of a trace and a trace is composed of a series of tagged time intervals known as spans It represents a logical unit of work in completing a process in a user request The key components and data points that make up a trace are as follows Root SpanIt s the parent span that represents the first span in a trace Child SpanA child span is triggered by a parent span and can be a function call DB calls calls to another service etc Duration or LatencyIt s the time taken by each span to complete its process It s a key data point used to analyze application performance Causal relationshipA trace relates all the spans involved in the request in a sequential relationship A trace is usually visualized as Flamegraphs or Gantt charts Below is a snapshot from the traces dashboard of SigNoz In the trace diagram below the root span spawns two child spans which call more inner processes Understanding the components of a trace spans duration amp the sequential flow of the requestYou can also add tags and span attributes to provide more context for your spans Span attributes are key value pairs that can be used to provide additional context on a span about the specific operation it tracks Tags provide you with additional context on spans Details associated with a span captured by SigNoz Deriving value from Distributed TracingDistributed tracing gives the much needed visibility into the operations of a complex distributed system It constructs a picture of how different distributed system components interact to process a user request Tracing data can be utilized at two levels Single Trace DataTracing data can be visualized in the form of Flamegraphs and Gantt Charts to reconstruct the entire flow of a specific user request This enables us to understand exactly what happened to that request in a particular component of the distributed system SigNoz shows Flamegraphs and Gantt charts both to make visualizing trace data easier In the dashboard below you can see the data for a single trace that consists of spans Flamegraphs and Gantt Charts visualizing the journey of a user request from a single trace data SigNoz Dashboard Aggregated Trace DataUsing tags and tracing data you can run aggregates to get relevant business metrics from the behavior of your distributed systems For example with SigNoz you can get the error rate and th percentile latency of customer type gold or deployment version v This enables quick analysis of services affecting a particular user group or type of requests SigNoz allows you to run aggregates on your tracing data and visualize them by important dimensions like service type operation HTTP status code etc SigNoz allows you to run aggregates on your tracing data and visualize them by important dimensions like service type operation HTTP status code etc Distributed tracing can also serve as a knowledge base for your engineering team It can act as a central overview dashboard that enables anyone to quickly get familiar with the application architecture Distributed Tracing with OpenTelemetryOpenTelemetry is an open source project under CNCF Cloud Native Computing Foundation that aims to standardize the process of creation and management of telemetry data like logs metrics and traces Other notable projects under CNCF are Kubernetes Helm and etcd OpenTelemetry is used to instrument application code to generate telemetry data Instrumentation is the process of enabling your application code to emit telemetry data For example you can use OpenTelemetry Java agent to instrument your Spring Boot applications to send out telemetry data automatically The question is why is OpenTelemetry important for the future of distributed tracing The reasons can be summarized in the following points Eliminates the risk of vendor lock inSaaS tools that provide distributed tracing capabilities have their own agents to instrument applications Whereas OpenTelemetry supports various popular data formats with the help of an exporter The data collected with OpenTelemetry can be sent to a backend of your choice Standard instrumentation across your distributed systemOpenTelemetry covers all major frameworks protocols and programming languages It also comes with a collector that can be used to collect and export data It enables OpenTelemetry to be the single source of instrumentation across your entire distributed system Open source and community backedA huge community is working on OpenTelemetry to make it the standard way of collecting and sending telemetry data to a backend platform It is also supported by all the major cloud vendors Ability to monitor emerging technologiesOpenTelemetry has a wide number of libraries and SDKs for instrumenting code in various programming languages If you decide to use any new technology OpenTelemetry can readily be used to instrument it and you don t have to depend on propriety monitoring tools to extend that capability Getting started with Distributed TracingSigNoz is an open source APM tool that provides distributed tracing as one of its main capabilities It is built to natively support OpenTelemetry so that you can build your entire monitoring stack with open source tools It provides both metrics monitoring and distributed tracing with an ability to correlate metrics and traces seamlessly For example you can view traces at a particular timestamp where metrics like application latency are poor and then you can dig deeper with traces generated around that timestamp Metrics monitoring with SigNozSigNoz comes with out of box visualizations for your tracing data The Traces dashboard of SigNoz provides you with powerful filters that can be used to analyze your tracing data The Traces tab of SigNoz provides powerful filters like service name status HTTP status code operation etc to analyze your traces data quicklyThe traces tab of SigNoz provides powerful filters like service name status HTTP status code operation etc to analyze your traces data quicklyYou can see all the spans based on selected filters and the chosen time period And you can also visualize how a particular span performed as part of an entire user request with Flamegraphs and Gantt Charts SigNoz can be installed on macOS or Linux computers in just three steps by using a simple install script The install script automatically installs Docker Engine on Linux However on macOS you must manually install Docker Engine before running the install script git clone b main https github com SigNoz signoz gitcd signoz deploy install shYou can visit our documentation for instructions on how to install SigNoz using Docker Swarm
