Performance Monitoring Event
Relative Slow Script Execution is used to generate an event when script execution is lower or higher than the average script execution time. Parameters should be set to a certain percentage for moderate and severe alerts.
The default values for this event type are set to 0. To generate events, configure these settings to a value that suits required script run-time.
Additional Rules:
Suppress in case a "Slow Function Execution" event occurs. Selecting this option ignores "Slow Script Execution" events that are caused by a slow function. This is to prevent double reporting, as these events will be reported as "Slow Function Execution" events.
Suppress in case the load average is above x - Selecting this option ignores events that occur when the average number of active processes waiting for CPU time is above x active processes (3 active processes is the default value).
Note:
These additional rules are defined in the Absolute Slow Script execution cell.
Relative Events: event definitions are based on relative values i.e. percentage. Relative values are set according to warm-up settings, default value of 500 requests.
If necessary, the default value can be modified manually by changing the zend_monitor.warmup_requests directive in the zend.ini.
