Collecting cluster summary diagnostics

Enable the cluster_summary_stats_options parameter in dse.yaml.

The following cluster summary diagnostic tables collect statistics at a cluster-wide level:
  • cluster_snapshot

    Per node system metrics.

  • dc_snapshot

    Aggregates node_snapshot data at the data center level.

  • node_snapshot

    Aggregates node_shapshot data for the whole cluster.

Procedure

  1. Edit the dse.yaml file.

    The location of this file depends on the type of installation:

    • Installer-Services and Package installations: /etc/dse/dse.yaml
    • Installer-No Services and Tarball installations: install_location/resources/dse/conf/dse.yaml
  2. In the dse.yaml file, set the enabled option for cluster_summary_stats_options to true.
    # Cluster summary stats options
    cluster_summary_stats_options: 
        enabled: true
        refresh_rate_ms: 10000
  3. (Optional) To control how often the statistics are refreshed, increase or decrease the refresh_rate_ms parameter.

    The refresh_rate_ms specifies the length of the sampling period, that is, the frequency with which this data is updated.
