Collecting slow Solr queries
The solr_slow_sub_query_log retains query information of long-running CQL statements to help you identify slow queries on a cluster so that you can tune poorly performing queries. Enable the solr_slow_sub_query_log_options parameter in dse.yaml.
The solr_slow_sub_query_log_options performance object reports distributed sub-queries (query executions on individual shards) that take longer than a specified period of time.
All objects are disabled by default.
The location of the dse.yaml file depends on the
type of installation:
Installer-Services | /etc/dse/dse.yaml |
Package installations | /etc/dse/dse.yaml |
Installer-No Services | install_location/resources/dse/conf/dse.yaml |
Tarball installations | install_location/resources/dse/conf/dse.yaml |
