Message latency metrics

Monitor messaging latency by adding dashboard graph metrics and alerts at the datacenter or node level.

Monitor messaging latency by adding dashboard graphs and alerts for latency metrics at the datacenter or node level. Messaging latency metrics are available for DSE versions 5.1.0 and later.

Datacenter Messaging Latency [cross-dc-latency]
The min, median, max, 90th, and 99th percentiles of the message latency between nodes in the same or different destination datacenter. This metric measures how long it takes a message from a node in the source datacenter to reach a node in the destination datacenter. Selecting a destination node within the source datacenter yields lower latency values.
Node Messaging Latency [cross-node-latency]
The min, median, max, 90th, and 99th percentiles of the latency of messages between nodes. The time period starts when a node sends a message and ends when the current node receives it.
