Introduction:

This article will discuss what the different values of the Performance Status Metric mean, as reported for each Monitor monitored by the APM ASM agent.

Instructions:

The Performance Status Metric reports a metric in Introscope, for each monitor defined in ASM. When a monitor is configured in ASM, a user specifies two limits, a first and second, measured as time in seconds. The first limit represents that maximum number of seconds a monitor should take to execute and still be considered as 'good performance'. The second limit is the minimum number of seconds a monitor should take before considered as 'bad performance'. The period in between is considered a warning state or 'poor performance'.

In Introscope, the Performance Status metric reports a value of 1, 2, 3 depending upon the execution time reported on the last run of a given monitor in relation to limits set on the monitor in ASM. A value of 1 for this metric indicates that the last run of this monitor occurred in a time less than the first limit defined for the monitor, or 'good performance'. A value of 2 indicates that the last run of the monitor exceeded the time defined as the first limit for the monitor. In Introscope, a value of 2 includes both 'poor performance' and 'bad performance'. A value of 3 indicates that the monitor failed to responds during the monitor's last execution. This typically occurs because the monitor timed out and exceeded the defined timeout value in ASM. This event is logged in the ASM UI in the log file for the monitor.

The information reported by the Performance Status Metric in Introscope can also be found within ASM "Performance Chart" page. On this page, 'good performance' is indicated with a green icon, 'poor performance' with a yellow icon, and 'bad performance' with a red icon.
