Collecting cache statistics

The solr_cache_stats_options object records current and cumulative cache statistics.

The following diagnostic tables collect cache statistics:

Filter cache statistics

Record core-specific query result cache statistics over time.
Query result cache statistics

Record core-specific query result cache statistics over time.

All objects are disabled by default.

Where is the dse.yaml file?

The location of the dse.yaml file depends on the type of installation:

Installation Type Location

Installation Type	Location
Package installations + Installer-Services installations	`/etc/dse/dse.yaml`
Tarball installations + Installer-No Services installations	`<installation_location>/resources/dse/conf/dse.yaml`

Package installations + Installer-Services installations

/etc/dse/dse.yaml

Tarball installations + Installer-No Services installations

<installation_location>/resources/dse/conf/dse.yaml

Procedure

In the dse.yaml file, under the solr_cache_stats_options parameter, change enabled to true and set the other options as required.
