This rule quantifies the latency for a given scenario that may be perceived by an end user. The latency is measured by collecting the runtime for each synthetic transaction execution.
Latency may be caused by a variety of factors including network delays or overloaded servers.
Please look at the Synthetic Transactions Performance view for historical latency details. The root cause may be able to be identified by cross referencing spikes in latency with other related alerts, or by using the specific synthetic transaction from the command line to pin-point where the delay is occurring.
