Collecting object I/O level diagnostics
Collect data on object I/O statistics. Enable and set the resource_level_latency_tracking_options parameter in dse.yaml.
The following object I/O level diagnostic tables collect data on object I/O
statistics:
- object_io
Per node recent latency metrics by keyspace and table.
- object_read_io_snapshot
Per node recent latency metrics, broken down by keyspace and table and orders data by mean read latency.
- object_write_io_snapshot
Per node recent latency metrics, broken down by keyspace and table and orders data mean write latency.
Procedure
To enable the collection of this data:
