It triggers the memory\/Resource Reclamation (RR) process in TDM, when the amount of free memory drops below a configurable threshold. RR process can also be triggered by memory allocation failures which results in a notification being sent to TDM to try to reclaim memory.<\/p>\n Selfheal is another feature implemented in Test And Diagnostic Component.<\/p>\n Self-heal monitors:<\/p>\n Self-heal stores Reset Count and Reboot Count. <\/p>\n\n\n Monitors the resources periodically (eg: 15 mins).\u00a0If “Average Memory Used” reaches threshold value, necessary action will be executed.\u00a0<\/p>\n “resource_monitor.sh” script is used for monitoring Memory and CPU usage. Monitors the processes periodically (eg: 15 mins) based on process id (pid).\u00a0Based on the process id availability, required action will be taken such as restarting the process, rebooting the device. “task_health_monitor.sh” script is used for monitoring RDK-B processes. This is located at path: “\/usr\/ccsp\/tad\/task_health_monitor.sh”. We can monitor any RDK-B processes by adding the process pid in this script.<\/p>\n Self-heal stores Reset Count and Reboot Count<\/p>\n Self-heal does connectivity test. Ping test will be done through server IP\/URI (this needs to be configured). If server IP\/URI is not configured, Ping test won’t be executed and no action will be taken.
