Collecting object I/O level diagnostics
The following object I/O level diagnostic tables collect data on object I/O statistics:
Per node recent latency metrics by keyspace and table.
Per node recent latency metrics, broken down by keyspace and table and orders data by mean read latency.
Per node recent latency metrics, broken down by keyspace and table and orders data mean write latency.
To enable the collection of this data:
dse.yamlfile, set the enabled option for
resource_level_latency_tracking_options: enabled: true refresh_rate_ms: 10000
(Optional) To control how often the statistics are refreshed, increase or decrease the
refresh_rate_msspecifies the length of the sampling period, that is, the frequency with which this data is updated.
