The solr_cache_stats_options object records current and cumulative cache statistics.

The following diagnostic tables collect cache statistics:

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, under the solr_cache_stats_optionsparameter, change enabled to true and set the other options as required.
    # Solr cache statistics options
    solr_cache_stats_options:
        enabled: true
        ttl_seconds: 604800
        refresh_rate_ms: 60000

    All objects are disabled by default.
