Monitoring System Latency

The second type of rule uses the time_since_process_status function to alarm if a specific data feed is interrupted. We recommend this grouping for ALERT2 systems that use two or more ports to send data to Contrail. There should be a rule written for each active port associated with the system. An example of this type of alarm would be time_since_process_status(CATEGORY, ID) >= MINUTES, where MINUTES is the number of minutes since the last process status update. Process status infomration is available to licensed Contrail owners, under Configuration > Settings > Status. Examples of Service processes include ALERT2 ASCII, USGS, and Alarms. For these examples, the CATEGORY is the Category specified for each given process (i.e. alert2-port-60012, USGS, CheckAlarms). The ID is the Service key specified for each defined Service. This can be found in Configuration > Settings > Services, then select a Service of interest (i.e. ALERT2 ASCII) to find the key information.
