Chapter 6. Viewing cluster logs using Kibana
The cluster logging installation deploys the Kibana web console.
6.1. Launching Kibana
Kibana is a browser-based console to query, discover, and visualize your logs through histograms, line graphs, pie charts, heat maps, built-in geospatial support, and other visualizations.
Prerequisites
If you installed OpenShift Container Platform with a proxy, you need to add .apps.<cluster_name>.<base_domain> to the noProxy list in your cluster-wide Proxy object.
For example:
$ oc edit proxy/cluster
apiVersion: config.openshift.io/v1
kind: Proxy
metadata:
creationTimestamp: "2020-03-30T00:45:44Z"
generation: 3
name: cluster
resourceVersion: "26654"
selfLink: /apis/config.openshift.io/v1/proxies/cluster
uid: 2213b41b-0721-4c9f-9586-0678c0058f85
spec:
httpProxy: http://proxy.com
httpsProxy: https://proxy.com
noProxy: .apps.mycluster.example.com 1
trustedCA:
name: user-ca-bundle- 1
- Add
.apps.<cluster_name>.<base_domain>to thenoProxylist. This is a comma-separated list of destination domain names, domains, IP addresses, or other network CIDRs to exclude proxying.
Procedure
To launch Kibana:
-
In the OpenShift Container Platform console, click Monitoring
Logging. Log in using the same credentials you use to log in to the OpenShift Container Platform console.
The Kibana interface launches. You can now:
- Search and browse your data using the Discover page.
- Chart and map your data using the Visualize page.
Create and view custom dashboards using the Dashboard page.
Use and configuration of the Kibana interface is beyond the scope of this documentation. For more information, on using the interface, see the Kibana documentation.
If you get a security_exception error in the Kibana console and cannot access your Kibana indices, you might have an expired OAuth token. If you see this error, log out of the Kibana console, and then log back in. This refreshes your OAuth tokens and you should be able to access your indices.
