Collecting request handler metrics

How to enable the solr_request_handler_metrics_options parameter in dse.yaml and set options.

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.

Procedure

  1. Edit the dse.yaml file.

    dse.yaml

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

    Package installations
    Installer-Services installations

    /etc/dse/dse.yaml

    Tarball installations
    Installer-No Services installations

    installation_location/resources/dse/conf/dse.yaml
  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.

    Table 1. Options
    Options Determines
    enabled Whether the object is enabled at start up.
    ttl_seconds How many seconds a record survives before it is expired from the performance object.
    refresh_rate_ms Period (in milliseconds) between sample recordings for periodically updating statistics like the solr_result_cache_stats.
