Start monitoring for a Kubernetes (kube) cluster.
start-monitoring-kube command creates a database where cluster information is stored and establishes pipelines for streaming data into it.
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 environment variable or the
~/. file are used to discover the clusters.
--config-file option to specify a custom kube config to use.
If multiple SingleStoreDB clusters are available in the provided
kubeconfig, use the
--context options to specify the the desired cluster.
Wrap the password string in single quotes (') to avoid having the shell try to interpret any special characters included in the string.
Usage:sdb-admin start-monitoring-kube [flags]For flags that can accept multiple values (indicated by VALUES after the name of the flag),separate each value with a comma.Flags:--batch-interval MILLISECONDS Time interval between data collections in milliseconds (default 60000)--cluster-name string The specific cluster name of the Metrics cluster--collect-event-traces Collect event traces.
