start-monitoring-kube

Description

Start monitoring for a Kubernetes (kube) cluster. SingleStore 7.1.8 is the minimum version required to run the start-monitoring-kube command.

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

The 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 ~/.kube/config file are used to discover the clusters. Use the --config-file option to specify a custom kube config to use.

If multiple clusters are available in the provided kubeconfig, use the --namespace, --cluster-name, and/or --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

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. Event tracing must be enabled on the Source cluster. (SingleStore 8.5 and later)
      --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)
      --container string                  The name of the container in which to run the command. If not specified, the default container will be used (ADVANCED)
      --context string                    The specific context to switch to when a kubeconfig has multiple contexts (ADVANCED)
      --database-name string              Monitoring database name (default "metrics")

      --exporter-port PORT                Port where memsql_exporter is run (on the Source cluster) (default 9104)
  -h, --help                              Help for start-monitoring-kube
      --high-cardinality-metrics          Collect high cardinality metrics. SingleStore recommends to set --batch-interval to at least 60000 if high-cardinality-metrics is enabled
      --monitoring-version string         Version of the cluster running monitoring
      --namespace string                  The Kubernetes namespace containing the Master Aggregator node of the Metrics cluster
      --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

      --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")
Global Flags:
      --backup-cache FILE_PATH                File path for the backup cache
      --cache-file FILE_PATH                  File path for the Toolbox node cache
  -c, --config FILE_PATH                      File path for the Toolbox configuration
      --disable-colors                        Disable color output in console, which some terminal sessions/environments may have difficulty with
      --disable-spinner                       Disable the progress spinner, which some terminal sessions/environments may have issues with
