Description
Configure process level memory monitoring. Because you cannot specify a threshold for all processes, an algorithm (heuristics-based) is used to identify the processes that are likely to cross the threshold. The algorithm can identify the processes based on learning the memory growth pattern of the processes and comparing the memory usage of the processes with the baseline of the process. The algorithm measures the virtual memory footprint, increase in memory foot print since baseline, and memory growth pattern score to identify the processes. You can also specify exceptions. Learning is always on at the configured time interval for process monitoring. Also, prediction is possible only when the module is aware that the system is running low on memory.
The remaining statements are explained separately.
Options
| frequency | Specify the frequency of system level memory monitoring. You can specify the frequency in days, hours or minutes. Possible values: 1 through 65535. |
| minor-event | Indicates a non-critical event that, if left unchecked, may cause an interruption in service or degradation in performance but does not significantly affect the device. |
| major-event | Indicates an event that, if left unchecked, may result in significant loss of service or interruption of traffic. |
| critical-event | Indicates an event that, if left unchecked, may result in serious loss of service or interruption of traffic. In case a critical event is triggered, you can terminate the process but only if the device is running out of memory. |
