Excluding keyspaces and tables from data collection 

By default, OpsCenter does not collect performance data for its own keyspace or the Cassandra system keyspace. You can manually add any other keyspaces or tables that you do not want to monitor in the [cassandra_metrics] section of the cluster_name.conf configuration file.

By default, OpsCenter does not collect performance data for its own keyspace or the Cassandra system keyspace. You can manually add any other keyspaces or tables that you do not want to monitor in the [cassandra_metrics] section of the cluster_name.conf configuration file. For example, to prevent data collection for the keyspace test as well as the table Keyspace1.Standard1, uncomment and edit the following values in the OpsCenter cluster configuration file (cluster_name.conf):


[cassandra_metrics] 
ignored_keyspaces = system, OpsCenter, test 
ignored_column_families = Keyspace1.Standard1
Tables (formerly column families) are specified in the format:
<keyspace_name>.<column_family_name>.
Note: Configuration properties still refer to tables as column families in OpsCenter.

cluster_name.conf 

The location of the cluster_name.conf file depends on the type of installation:

  • Package installations: /etc/opscenter/clusters/cluster_name.conf
  • Tarball installations: install_location/conf/clusters/cluster_name.conf
