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.

dse.yaml

The location of the dse.yaml file depends on the type of installation:
Package installations /etc/dse/dse.yaml
Tarball installations installation_location/resources/dse/conf/dse.yaml

Procedure

  1. Edit the dse.yaml file.
  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
