Metrics Collection Properties 

Use these metrics properties to limit the keyspaces and tables (column families) for metrics collection and change default expiration periods (ttl) for performance data.

[cassandra_metrics] ignored_keyspaces
A list of keyspaces to not collect metrics for, separated by commas. The default value is system, system_traces, system_auth, dse_auth, and OpsCenter.
[cassandra_metrics] ignored_column_families
A list of tables to not collect metrics for, separated by commas. Each entry should be of the form "ks.cf". For example: metrics_ignored_column_families = system.NodeInfo, system.Schema, Keyspace1.Standard1
[cassandra_metrics] ignored_solr_cores
A list of solr cores to not collect metrics for, separated by commas. Each entry should be of the form "ks.cf". For example: metrics_ignored_solr_cores = Keyspace1.Standard1, solr.wiki.

These properties set the expiration time for data stored in the OpsCenter keyspace. Each time period for rolling up data points into summary views has a separate expiration threshold, or time-to-live (ttl) value expressed in seconds. By default, shorter time periods have lower values that result in more efficient expiration and compaction of the relatively larger volumes of data. Uncomment these properties to change the default expiration periods for performance data. Properties and default values are:

[cassandra_metrics] 1min_ttl
Sets the time in seconds to expire 1 minute data points. The default value is 604800 (7 days).
[cassandra_metrics] 5min_ttl
Sets the time in seconds to expire 5 minute data points. The default value is 2419200 (28 days).
[cassandra_metrics] 2hr_ttl
Sets the time in seconds to expire 2 hour data points. The default value is 31536000 (365 days).
[cassandra_metrics] 24hr_ttl
Sets the time to expire 24 hour data points. The default value is 0, or never.
