start-monitoring

Description

Start monitoring. SingleStore 7.1.8 is the minimum version required to run the start-monitoring command.

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

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

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

Wrap the password string in single quotes (') to avoid having the shell try to interpret any special characters included in the string.

Usage

Usage:
sdb-admin start-monitoring [flags]

--database-name string Monitoring database name (default "metrics")
--disable-sample-queries Disables queries sampling
--exporter-host string Host where memsql_exporter is run (on the Source cluster)
--exporter-port PORT Port where memsql_exporter is run (on the Source cluster) (default 9104)
-h, --help Help for start-monitoring
--high-cardinality-metrics Collect high cardinality metrics. It is recommended to set --batch-interval to at least 60000 if high-cardinality-metrics is enabled
--monitoring-version string Version of the cluster running monitoring
--password string The database user's password for connecting to SingleStore (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-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)
--ssl-ca string Path to the CA certificate to use with HTTPS. When specified, pipelines will attempt to connect to the exporter via HTTPS. The certificate must exist on all hosts that contain a leaf node
--ssl-capath string Path to the directory that contains the CA certificates to use with HTTPS. When specified, pipelines will attempt to connect to the exporter on the Source cluster via HTTPS. The directory must exist on all hosts that contain a leaf node
--user string The database user for connecting to SingleStore (on the Metrics cluster) (default "root")
