This host-level alert is triggered if the JobTracker operations RPC latency exceeds the configured critical threshold. Typically an increase in the RPC processing time increases the RPC queue length, causing the average queue wait time to increase for JobTracker operations. This alert uses the Nagios check_rpcq_latency plugin.
