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. Depending on consistency level and replication factor, this may include the network latency from requesting the data’s replicas.

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