Start monitoring for a Kubernetes (kube) cluster.

Usage

The 'start-monitoring-kube' command creates a database where cluster information is stored and establishes pipelines for streaming data into it.

The 'sdb-admin start-monitoring-kube' command must be run from a computer which can access the Master Aggregator node of the Metrics cluster which is running within the Kubernetes cluster.

By default, the KUBECONFIG env variable or the ~/.kube/config file are used to discover the clusters. Use the --config-file option to specify a custom kube config to use.

If multiple SingleStoreDB clusters are available in the provided kubeconfig, use the --namespace, --cluster-name, and/or --context options to specify the the desired cluster.

SingleStoreDB 7.1.8 is the minimum version required to run 'start-monitoring-kube'.

Usage:
  sdb-admin start-monitoring-kube [flags]

      --config-file FILE_PATH             The kubeconfig file path. Leave blank if the path is stored in the KUBECONFIG env variable or in the ~/.kube/config file (ADVANCED)
      --context string                    The specific context to switch to when a kubeconfig has multiple contexts (ADVANCED)
      --database-name string              Monitoring database name (default "metrics")

      --namespace string                  The Kubernetes namespace containing the Master Aggregator node of the Metrics cluster
      --password string                   The database user's password for connecting to SingleStoreDB (on the Metrics cluster). If a password is specified on the command line, it must not contain an unescaped '$' character as it will be replaced by the shell
      --purge-frequency MINUTES           Time between purges of expired monitoring data for a specific Source cluster (default 60)
      --purge-log-retention-period DAYS   Period of time to retain purge log entries (ADVANCED) (default 365)
      --retention-period DAYS             Period of time to retain monitoring data for a specific Source cluster (default 7)
      --user string                       The database user for connecting to SingleStoreDB (on the Metrics cluster) (default "root")

Global Flags:
