Monitors the CPU core usage (\%) for a BIG-IP device.
This monitor checks the current CPU core usage (in percentages) for a BIG-IP device. If the collected value exceeds or is equal to the threshold value consecutively for the specified number of times, the critical state is triggered.
The following configuration parameters are customizable:
Debug | When true, writes more information into event log. Default value is false. |
Use Cache | If true, cache will be used, in order to minimize impact of monitoring on the F5 BIG-IP device. Default value is true. |
Number Of Samples | Number of consecutive sample values considered before generating an alert. Default value is 3. |
Port | Port for accessing the BIG-IP device. Default value is 443. |
Synchronization Time | Synchronization time in a 24-hour format. No default value is specified. |
Threshold | The threshold value for usage percentage of CPU core. Default value is 100. |
Timeout Seconds | Timeout in seconds. This value is used for setting timeout value to access the BIG-IP device. Default value is 270 seconds. |
Update Interval in Seconds | Recurring scheduled interval in seconds used for running the workflow. Default value is 300 seconds. |
Extended high CPU utilization can degrade performance, and the system may eventually become unresponsive or reboot.
