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 datacenter level.

  • node_snapshot

    Aggregates node_snapshot data for the whole cluster.


  1. Edit the dse.yaml file.
    The location of the dse.yaml file depends on the type of installation:
    Installer-Services /etc/dse/dse.yaml
    Package installations /etc/dse/dse.yaml
    Installer-No Services install_location/resources/dse/conf/dse.yaml
    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
        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.
