OpsCenter Metrics Tooltips Reference

Comprehensive reference of performance metrics available in OpsCenter.

Metrics are available to add to any graph. View descriptions of any metric by hovering over a metric in the Add Metric dialog, or by hovering over a graph legend.

The following list of metric descriptions available in tooltips is provided for your convenience:

Write Requests 
The number of write requests per second on the coordinator nodes, analogous to client writes. Monitoring the number of requests over a given time period reveals system write workload and usage patterns.
Write Request Latency (percentiles) 
The min, median, max, 90th, and 99th percentiles of a client writes. The time period starts when a node receives a client write request, and ends when the node responds back to the client. Depending on consistency level and replication factor, this may include the network latency from writing to the replicas.
Write Failures 
The number of write requests on the coordinator nodes that fail due to errors returned from replicas.
Write Timeouts 
The number of server write timeouts per second on the coordinator nodes.
Write Unavailable Errors 
The number of write requests per second on the coordinator nodes, that fail because not enough replicas are available.
Read Requests 
The number of read requests per second on the coordinator nodes, analogous to client reads. Monitoring the number of requests over a given time period reveals system read workload and usage patterns.
Read Request Latency (percentiles) 
The min, median, max, 90th, and 99th percentiles of a client reads. The time period starts when a node receives a client read request, and ends when the node responds back to the client.

Read Failures 
The number of read requests on the coordinator nodes that fail due to errors returned from replicas.

Task Queues 
Aggregate of thread pools pending queues that can be used to identify where things are backing up internally. This doesn't include pending compactions because it includes an estimate outside of the task queue or the hinted hand off queue, which can be in constant state of being on.
Dropped Messages: All 
Aggregate of all messages that have been dropped server-side due to not having been processed before their respective timeout.
Dropped Messages: Counter Mutations 
Mutation was seen after the timeout (write_request_timeout_in_ms) so was thrown away. This client might have timed out before it met the required consistency level, but might have succeeded as well. Hinted handoffs and read repairs should resolve inconsistencies but a repair can ensure it.
Dropped Messages: Mutations 
Mutation was seen after the timeout (write_request_timeout_in_ms) so was thrown away. This client might have timed out before it met the required consistency level, but might have succeeded as well. Hinted handoffs and read repairs should resolve inconsistencies but a repair can ensure it.
Dropped Messages: Reads 
A local read request was received after the timeout (read_request_timeout_in_ms) so it was thrown away because it would have already either been completed and sent to client or sent back as a timeout error.
Dropped Messages: Ranged Slice Reads 
A local ranged read request was received after the timeout (range_request_timeout_in_ms) so it was thrown away because it would have already either been completed and sent to client or sent back as a timeout error.
Dropped Messages: Read Repairs 
The Mutation was seen after the timeout (write_request_timeout_in_ms) so was thrown away. With the read repair timeout, the node still exists in an inconsistent state.
