Analyzing a Cluster

Perform analysis on the state of Kubernetes cluster using the ocne cluster analyze command.

This might be useful for debugging any issues with the Kubernetes cluster.

You can create a set of dump files to analyze using the ocne cluster dump command. Or you can analyze a live, running, cluster without first creating a set of dump files.

(Optional) Generate dump files of the Kubernetes cluster.

Use the ocne cluster dump command to generate a dump file of the Kubernetes cluster. The syntax to use is:

ocne cluster dump 
[{-c|--curated-resources}]
[{-z|--generate-archive} path]
[{-m|--include-configmaps}]
[{-n|--namespaces} namespace,...]
[{-N|--nodes} nodename, ...]
[{-d|--output-directory} path]
[{-r|--skip-cluster}]
[{-s|--skip-nodes}]
[{-p|--skip-pod-logs}]
[{-t|--skip-redaction}]

For more information on the syntax options, see Oracle Cloud Native Environment: CLI.

For example:

ocne cluster dump --output-directory $HOME/dump

Analyze the state of the cluster.
Use the ocne cluster analyze command to analyze the state of the cluster. The syntax is:
```
ocne cluster analyze 
[{-d|--dump-directory} path]
[{-s|--skip-nodes}]
[{-p|--skip-pod-logs}]
[{-v|--verbose}]
```
For more information on the syntax options, see Oracle Cloud Native Environment: CLI.

For example:

To analyze a live cluster:
```
ocne cluster analyze
```
To analyze a live cluster without including node data:
```
ocne cluster analyze --skip-nodes
```
To perform a basic analysis of cluster dump files:
```
ocne cluster analyze --dump-directory $HOME/dump/
```
To display more detailed information of cluster dump files:
```
ocne cluster analyze --dump-directory $HOME/dump/ --verbose
```
