What is cluster logging?

The cluster logging components are based upon Elasticsearch, Fluentd, and Kibana (EFK). It collects all node and container logs and writes them to Elasticsearch (ES). Kibana is the centralized, web UI where users and administrators can create rich visualizations and dashboards with the aggregated data.

What is OpenShift logging?

The OpenShift logging stack is an OpenShift component that is ubiquitous in most enterprise clusters. It acts as a virtual witness to cluster activity and provides a scalable mechanism for recording everything that happens inside the cluster.

What is Efk?

What is EFK. EFK is a suite of tools combining Elasticsearch, Fluentd and Kibana to manage logs. Fluentd will collect the logs and send it to Elasticsearch. This latter will receive the logs and save it on its database. Kibana will fetch the logs from Elasticsearch and display it on a nice web app.

What is Efk in OpenShift?

As an OpenShift Enterprise cluster administrator, you can deploy the EFK stack to aggregate logs for a range of OpenShift Enterprise services. The EFK stack aggregates logs from hosts and applications, whether coming from multiple containers or even deleted pods.

What do you need to know about cluster level logging?

In a cluster, logs should have a separate storage and lifecycle independent of nodes, pods, or containers. This concept is called cluster-level logging. Cluster-level logging architectures require a separate backend to store, analyze, and query logs.

How do I generate a cluster log file?

You can generate the cluster logs in two ways: Use the cluster /log /g command at the command prompt. This command generates the cluster logs to the \\windows\\cluster\\reports directory on each WSFC node. Use the Get-ClusterLog PowerShell cmdlet.

How does cluster logging work in OpenShift Container Platform?

By default, OpenShift Container Platform cluster logging sends logs to the default internal Elasticsearch log store, defined in the ClusterLogging custom resource (CR). If you want to forward logs to other log aggregators, you can use the log forwarding features to send logs to specific endpoints within or outside your cluster.

How to increase verbosity of cluster.log?

You can increase the verbosity of the logs in CLUSTER.LOG for an availability group. To modify the verbosity, follow the steps below: From the Start menu, open the Failover Cluster Manager. Expand your cluster and the Services and applications node, then click the availability group name.
