Collecting request handler metrics

Steps to enable the solr_request_handler_metrics_options parameter in dse.yaml and set the other options as required. The solr_request_handler_metrics_options object records core-specific direct and request update handler statistics over time.

The following diagnostic tables collect handler metrics:

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

Package installations + Installer-Services installations

/etc/dse/dse.yaml

Tarball installations + Installer-No Services installations

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

Procedure

  1. Edit the dse.yaml file.

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

    # Solr request handler metrics options
    solr_request_handler_metrics_options:
        enabled: true
        ttl_seconds: 604800
        refresh_rate_ms: 60000

    All objects are disabled by default.
