How do I monitor ETCD Kubernetes?

You can check the metrics available for your version in the Kubernetes repo (link for the 1.15. 3 version). This should give the number of nodes running, if some node is down you can see it and the worst case would be if the number is 0 then you will know there is a problem.

How do you expose ETCD metrics?

The simplest way to see the available metrics is to cURL the metrics endpoint /metrics . The format is described here. Follow the Prometheus getting started doc to spin up a Prometheus server to collect etcd metrics. The naming of metrics follows the suggested Prometheus best practices.

How do you check ETCD metrics?

Each etcd server exports metrics under the /metrics path on its client port. The metrics can be fetched with curl : $ curl -L http://localhost:2379/metrics # HELP etcd_debugging_mvcc_keys_total Total number of keys.

What can you monitor with Prometheus?

Using Prometheus, you can monitor application metrics like throughput (TPS) and response times of the Kafka load generator (Kafka producer), Kafka consumer, and Cassandra client. Node exporter can be used for monitoring of host hardware and kernel metrics.

What is the role of Prometheus in a Kubernetes cluster?

Prometheus is an open-source instrumentation framework. ... Use Prometheus to monitor your servers, VMs, databases, and draw on that data to analyze the performance of your applications and infrastructure. This article explains how to set up Prometheus monitoring in a Kubernetes cluster.

How do I check my ETCD cluster status?

Host health

To verify that the cluster is up and running, connect to a master instance, and run the following: ...
Before you run etcd commands, source the etcd.conf file: ...
You can check the basic etcd health status from any master instance with the etcdctl command:

How does ETCD cluster work?

etcd is built on the Raft consensus algorithm to ensure data store consistency across all nodes in a cluster—table stakes for a fault-tolerant distributed system. Raft achieves this consistency via an elected leader node that manages replication for the other nodes in the cluster, called followers.

Why does Kubernetes use ETCD?

Kubernetes uses etcd to store all its data – its configuration data, its state, and its metadata. Kubernetes is a distributed system, so it needs a distributed data store like etcd. etcd lets any of the nodes in the Kubernetes cluster read and write data.

How do I check ETCD logs?

You can retrieve logs for each service with the master-logs api api , master-logs controllers controllers , or master-logs etcd etcd commands. If your cluster runs an aggregated logging stack, like an Ops cluster, cluster administrators can retrieve logs from the logging .

How do I find my ETCD configuration?

Multi-node etcd cluster

Configure an etcd cluster either by static member information or by dynamic discovery. For more information on clustering, see etcd clustering documentation. Start the Kubernetes API servers with the flag --etcd-servers=$IP1:2379,$IP2:2379,$IP3:2379,$IP4:2379,$IP5:2379 .
