Collecting handler statistics 

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

The Update handler statistics records core-specific direct update handler 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, uncomment the solr_update_handler_metrics_options parameter and set the options as required.
    # Solr UpdateHandler metrics options
    solr_update_handler_metrics_options:
        enabled: true
        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.
    ttl_seconds How many seconds a record survives before it is expired from the performance object.
    refresh_rate_ms Period (in milliseconds) between sample recordings for periodically updating statistics like the solr_result_cache_stats.
