start-monitoring

Info

MemSQL Helios does not support this command.

Start monitoring.

Usage

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

The 'sdb-admin start-monitoring' command must be run on the Master Aggregator host of the cluster in which to store the monitoring data (the Metrics cluster).

The Metrics cluster may be the same as the Source cluster.

The 'sdb-admin configure-monitoring' command must be run on the Master Aggregator of the Source (monitored) cluster before running the current command.

The 'sdb-admin start-monitoring' command will recreate the associated pipelines each time the command is run.

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

Usage:
  sdb-admin start-monitoring [flags]

      --batch-interval MILLISECONDS       Time interval between data collections in milliseconds (default 15000)
      --database-name string              Monitoring database name (default "metrics")

      --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
