• Resource monitoring: Monitors memory / cpu usage and if it goes beyond threshold, it reboots the device.
• Process monitoring: It will periodically monitors status of the critical processes.
  • Ccsp processes: If any of these processes crashed, it will be restarted via Self Heal.
  • "CcspCrSsp": If this process is crashed, device will be rebooted.
  • "syseventd": If syseventd is crashed, device will be rebooted.
• Connectivity test: If DNS or WAN_IP is down, device will stop the LAN functionality.

- It monitors CPU and MEMORY.

                1.  By default, AVG CPU threshold value will be set as 100. This value will be stored in syscfg database. If we want the change the default AVG CPU threshold value, Please refer the attached screenshot and do the following steps,

 - Monitors  the Process Periodically based on Process id's.

If it detects that any of the process is not running, it automatically restarts that particular Component.
