KPI | Use to monitor... |
JVM CPU Load | How much CPU the JVM uses. KPI values: Marginal is 80% CPU usage. Critical is 95% CPU usage. Maximum is 100% CPU usage. KPI limitations: supported only when running Java 7 or higher not reported when running on HP-UX |
JVM Memory | How much JVM memory the run-time component uses. KPI values: Marginal is calculates as follows: MAX(Maximum*80%, Maximum-100) A marginal value is when only 20% of the JVM memory is free or less than 100MB of JVM memory is available. Critical is calculated as follows: MAX(Maximum*95%, Maximum-50) A critical value is when only 5% of the JVM memory is free or less than 50MB of JVM memory is available. Maximum is the amount of memory allocated to the JVM. KPI limitation: the KPI value might be incorrect when running in a 32-bit operating system. |
JVM Threads | The number of JVM threads that the run-time component uses. KPI values: Marginal and Critical are the current number of the allocated JVM threads plus one thread: current+1. Maximum is the maximum allocated JVM threads plus one thread: MAX+1 |
