article you ll learn how to Monitor Consul with Prometheus Also troubleshoot Consul control plane with Prometheus from scratch following Consul s docs monitoring recommendations Also you ll find out how to troubleshoot the most common Consul issues How to install Consul in KubernetesInstalling Consul in Kubernetes is straightforward just take a look at the Consul documentation page and follow the instructions We recommend using the Helm chart since it s the easier way of deploying applications in Kubernetes How to configure Consul to expose Prometheus metricsConsul automatically exports metrics in the Prometheus format You just need to activate these options in the global metrics configurations If you re using Helm you can do it with set global metrics enabled true set global metrics enableAgentMetrics true Also you ll need to enable the telemetry disable hostname for both the Consul Server and Client so the metrics don t contain the name of the instances set server extraConfig telemetry disable hostname true set client extraConfig telemetry disable hostname true Monitor Consul with Prometheus Overall status AutopilotFirst you can check the overall health of the Consul server using the Autopilot metric consul autopilot healthy If all servers are healthy this will return and otherwise All non leader servers will report NaN You could add this PromQL query to your dashboard to check the overall status of the Consul server min consul autopilot healthy Adding these thresholds “Healthy “Unhealthy To trigger an alert when one or many Consul servers in the cluster are unhealthy you can simply use this PromQL consul autopilot healthy Want to dig deeper into PromQL Read our getting started with PromQL guide to learn how Prometheus stores data and how to use PromQL functions and operators Leadership changesConsul deploys several instances of the control plane controllers to ensure high availability However only one of them is the leader and the rest are for contingency A Consul cluster should always have a stable leader If it s not stable due to frequent elections or leadership changes you could be facing network issues between the Consul servers For checking the leadership stability you can use the following metrics consul raft leader lastContact Indicates how much time has passed since the leader contacted the follower nodes when checking its leader lease consul raft state leader Number of leaders consul raft state candidate Number of candidates to promote to leader If this metric returns a number higher than it means that a leadership change is in progress For a healthy cluster you re looking for a consul raft leader lastContact lower than ms a consul raft state leader greater than and a consul raft state candidate equal to Let s create some alerts to trigger if there is flapping leadership There are too many elections for leadership sum rate consul raft state candidate m gt There are too many leadership changes sum rate consul raft state leader m gt Leader time to contact followers is too high consul raft leader lastContact quantile gt The last query contains the label quantile for using the percentile By using the percentile p you re getting the of the samples that are taking more than ms to contact the leader Top troubleshooting situations to monitor Consul Long latency in Consul transactionsLong latency in Consul transactional operations could be due to an unexpected load on the Consul servers or the issues on the servers Anomalies need to be detected in a time context because the network is dynamic by nature and you can t just compare your samples with a fixed value You need to compare your values with other values in the last hour or the last day last five minutes… to determine if it s a desirable value or needs some attention To detect anomalies you can dust off your old statistics book and find the chapter explaining the normal distribution The of the samples in a normal distribution are between the average plus or minus two times the standard deviation To calculate this in PromQL you can use the avg over time and stddev over time functions like in this example avg rate consul kvs apply sum m gt gt avg over time rate consul kvs apply sum m h m stddev over time rate consul kvs apply sum m h m Let s see a few alerts that are triggered if the transaction latency isn t normal Key Value Store update time anomalyConsul KV Store update time had noticeable deviations from baseline over the previous hour avg rate consul kvs apply sum m gt gt avg over time rate consul kvs apply sum

event that blocks all runtime threads until the garbage collection completes This process takes just a few nanoseconds but if Consul s memory usage is high that could trigger more and more GC events that could potentially slow down Consul Let s create two alerts a warning alert if the GC takes more than two seconds per minute and a critical alert if the GC takes more than five seconds per minute

海外TECH	DEV Community	Read Committed is a must for Postgres-compatible distributed SQL databases	https://dev.to/franckpachot/read-committed-is-a-must-for-postgres-compatible-distributed-sql-databases-59pf	Read Committed is a must for Postgres compatible distributed SQL databasesIn SQL databases isolation levels are a hierarchy of update anomaly prevention Then people think that the higher is the better and that when a database provides Serializable there s no need for Read Committed However Read Committed is the default in PostgreSQL The consequence is that the majority of applications are using it and use SELECT FOR UPDATE to prevent some anomaliesSerializable doesn t scale with pessimistic locking Distributed databases must use optimistic locking and you need to code their transaction retry logicWith those two a distributed SQL database that doesn t provide Read Committed isolation cannot claim PostgreSQL compatibility because running applications that were build for PostgreSQL defaults is impossible YugabyteDB started with the the higher the better idea and Read Committed is transparently using Snapshot Isolation This is correct for new applications However when migrating applications build for Read Committed where you don t want to implement a retry logic on serializable failures SQLState and expect the database to do it for you You can switch to Read Committed with the yb enable read committed isolation gflag Note a GFlag in YugabyteDB is a global configuration parameter for the database documented in yb tserver reference The PostgreSQL parameters which can be set by the ysql pg conf csv GFlag concern only the YSQL API but GFlags covers all YugabyteDB layersIn this blog post I ll demo the real value of Read Committed isolation level there s no need to code a retry logic because at this level YugabyteDB can do it itself Start YugabyteDBI am starting a YugabyteDB single node database for this simple demo Franck YB docker run rm d name yb p p p p yugabytedb yugabyte bin yugabyted start daemon false tserver flags cacaeefebcbcaceadddabecI explicitly didn t set any GFlags to show the default behaviour This is version build I check the read committed related gflagsFranck YB curl s http localhost varz raw grep E yb enable read committed isolation ysql output buffer size ysql sleep before retry on txn conflict ysql max write restart attempts ysql default transaction isolation yb enable read committed isolation false ysql max write restart attempts ysql output buffer size ysql sleep before retry on txn conflict true ysql default transaction isolation Read Committed is the default isolation level by PostgreSQL compatibility Franck YB psql p c show default transaction isolation default transaction isolation read committed row I create a simple table Franck YB psql p ec create table demo id int primary key val int insert into demo select generate series create table demo id int primary key val int insert into demo select generate series INSERT I ll run the following update setting the default isolation level to Read Committed just in case but it is the default Franck YB cat gt update sql lt lt SQL timing on set VERBOSITY verboseset default transaction isolation to read committed update demo set val val where id watch SQLThis will update one row I ll run this from multiple sessions on the same row Franck YB timeout psql p ef update sql gt session txt amp Franck YB timeout psql p ef update sql gt session txt amp psql update sql ERROR Operation expired Transaction ac ccb e ab afefbc expired or aborted by a conflict LOCATION HandleYBStatusAtErrorLevel pg yb utils c Done timeout psql p ef update sql gt session txtFranck YB wait Exit timeout psql p ef update sql gt session txtOn session encountered Transaction expired or aborted by a conflict If you run the same several times you may also get Operation expired Transaction aborted kAborted All transparent retries exhausted Query error Restart read required or All transparent retries exhausted Operation failed Try again Value write after transaction start They are all ERROR which are serialization errors that expect the application to retry In Serializable the whole transaction must be retried and this is generally not possible to do transparently by the database that doesn t know what else the application did during the transaction For example some rows may have already been read and sent to the user screen or a file The database cannot rollback that The applications must handle that I ve set Timing on to get the elapsed time and as I m running this on my laptop there s not client server network significant time Franck YB awk Time print int session txt sort n uniq c Most updates were less than millisecond here But remember that the program failed on quickly so this is the normal one session workload on my laptop By default yb enable read committed isolation is false and in this case the Read Committed isolation level of YugabyteDB s transactional layer falls back to the stricter Snapshot Isolation in which case READ COMMITTED and READ UNCOMMITTED of YSQL use Snapshot Isolation yb enable read committed isolation trueNow changing this setting which is what you should do when you want to be compatible with your PostgreSQL application that doesn t implement any retry logic Franck YB docker rm f ybyb Exit timeout psql p ef update sql gt session txtFranck YB docker run rm d name yb p p p

committed isolation ysql output buffer size ysql sleep before retry on txn conflict ysql max write restart attempts ysql default transaction isolation yb enable read committed isolation true ysql max write restart attempts ysql output buffer size ysql sleep before retry on txn conflict true ysql default transaction isolation Running the same as above Franck YB psql p ec create table demo id int primary key val int insert into demo select generate series create table demo id int primary key val int insert into demo select generate series INSERT Franck YB timeout psql p ef update sql gt session txt amp Franck YB timeout psql p ef update sql gt session txt amp Franck YB wait Exit timeout psql p ef update sql gt session txt Exit timeout psql p ef update sql gt session txtI got no error at all and both sessions have been updating the same row during seconds Of course it wasn t exactly at the same time as the database had to retry many transactions which is visible in the elapsed time Franck YB awk Time print int session txt sort n uniq c While most of transactions are still less than milliseconds some when to milliseconds because of retries retry backoffA common retry waits an exponential amount of time between each retries up to a maximum This is what is implemented in YugabyteDB and the following parameters that can be set at session level controls it Franck YB psql p xec select name setting unit category short descfrom pg settingswhere name like retry backoff select name setting unit category short descfrom pg settingswhere name like retry backoff RECORD name retry backoff multipliersetting unit category Client Connection Defaults Statement Behaviorshort desc Sets the multiplier used to calculate the retry backoff RECORD name retry max backoffsetting unit mscategory Client Connection Defaults Statement Behaviorshort desc Sets the maximum backoff in milliseconds between retries RECORD name retry min backoffsetting unit mscategory Client Connection Defaults Statement Behaviorshort desc Sets the minimum backoff in milliseconds between retries With my local database transactions are short and I don t have to wait so much time When adding set retry min backoff to to my update sql the elapsed time is not inflated too much by this retry logic Franck YB awk Time print int session txt sort n uniq c VersionsThis was implemented in YugabyteDB and I m using here It is not yet implemented when running the transaction from DO or ANALYZE commands but works for procedures You can follow and comment issue if you want it in DO or ANALYZE In conclusionImplementing retry logic in the application is not a fatality but a choice in YugabyteDB A distributed database may raise more transaction conflicts because of clock skew but still needs to make it transparent to SQL applications If you want to prevent all transactions anomalies see this one as an example you can run in Serializable and handle the exception Don t be fooled by the idea that it requires more code because without it you need to test all race conditions which may be a bigger effort In Serializable the database ensures that you have the same behavior than running serially so that your unit tests are sufficient to guarantee correctness of data However with an existing PostgreSQL application using the default isolation level the behavior is validated by years of running in production What you want is not avoiding the possible anomalies because the application probably workaround them You want to scale out without changing the code This is where YugabyteDB provides the Read Committed isolation level which requires no additional error handling code	2022-04-29 09:18:52
