Collecting index statistics

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

To collect index statistics:

To permanently collect index statistics:

Edit the dse.yaml file.
The location of the dse.yaml file depends on the type of installation:
- Package installations and Installer-Services installations: /etc/dse/dse.yaml
- Tarball installations and Installer-No Services installations: <installation_location>/resources/dse/conf/dse.yaml

Change solr_index_stats_options.enabled to true, and then set the other options as required:

# Solr index statistics options
solr_index_stats_options:
    enabled: false
    ttl_seconds: 604800
    refresh_rate_ms: 60000

Options Determines

Options	Determines
`enabled`	Whether the object is enabled at start up. Default: `false`
`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.

enabled
