1. Introduction
Self Heal is a monitoring and recovery module.
It continuously monitors the system resources like CPU and Memory and monitors the critical Processes running.
Self heal also performs Connectivity tests.
In case of any problems encountered, Self Heal takes corrective actions like: Rebooting the device, Restarting required process based on predefined conditions.
Self-heal stores Reset Count and Reboot Count.
2. Environment Setup
Self Heal functionality is handled by a set of scripts. These scripts are available in the RDK build by default.
Please ensure that below Self heal scripts are present on the device at the path "/usr/ccsp/tad".
Please refer the below code snippet to verify self heal module was enabling by default or not,
root@Filogic-GW:/rdklogs/logs# dmcli eRT getv Device.SelfHeal.X_RDKCENTRAL-COM_Enable
CR component name is: eRT.com.cisco.spvtg.ccsp.CR

3. Executing System
Self Heal is enabled by default and is active at the time of boot up.
It periodically performs below actions.
- 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.

3.2. Process Monitor - 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.
Let us take the example of CcspLMLite Component :
-
Run a ps command to verify that CcspLMLite is up and running again with different process id
ps aux | grep Ccsp
2. kill CcspLMLite process by using the below command
kill -9 PID(CcspLMLite PID)
3. Verfiy whether the CcspLMLite Process was killed or not by using the below command
ps aux | grep Ccsp
4. After 60 seconds(default), it will automatically restart the Process. Please check the CcspLMLIte PID.
