Collecting index statistics 

Enable the solr_index_stats_options parameter in dse.yaml and set the other options as required.

The solr_index_stats_options object records core-specific index overview statistics over time.

All objects are disabled by default.

Procedure

  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, for the solr_index_stats_options parameter, change enabled to true and set the other options as required.
    # Solr index statistics options
    solr_index_stats_options:
        enabled: false
        ttl_seconds: 604800
        refresh_rate_ms: 60000

    All objects are disabled by default.

    Options
    Options Determines
    enabled Whether the object is enabled at start up.
    refresh_rate_ms Period (in milliseconds) between sample recordings for periodically updating statistics like the solr_result_cache_stats.
    ttl_seconds How many seconds a record survives before it is expired from the performance object.
