Greetings @phoenix. The Service Latency metric is the amount of time between when a cluster receives a query and finishes a query. Where the Transaction Latency is the aggregate estimate of the transactions load over the cluster.

In the cluster view, the Service Latency shows you the 99th percentile of service latency (the time a query takes to run) for each node in the cluster. The Transaction Latency shows you the per-node average of the current transactions load.
