Show Cluster Status
You can show the status information of the specified cluster with the following command:
ptk cluster -n <CLUSTER_NAME> status
If there are multiple clusters, you can list the status information of all clusters at once by specifying the -a
parameter without knowing the cluster name:
ptk cluster status -a
PTK also supports specifying the --detail
parameter to list the stream replication information for each instance in the cluster when viewing status:
ptk cluster -n <CLUSTER_NAME> status --detail
If the cluster status list is too wide to be easily viewed by folding the rows, you can add the -G
parameter to display it vertically:
ptk cluster -n <CLUSTER_NAME> status -G
