Collecting Apache Solr performance statistics

Enable the solr_latency_snapshot_options parameter in dse.yaml and set the other options as required.

When solr_latency_snapshot_options is enabled, the performance service creates the required tables and schedules the job to periodically update the relevant snapshot from the specified data source.

The following snapshots collect performance statistics:

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_latency_snapshot_options parameter, change enabled to true and set the other options as required.
    # Solr latency snapshot options
    solr_latency_snapshot_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.
