[Monit] Fix the issue which shows Monit can not reset its counter. (#10288)
Signed-off-by: Yong Zhao <yozhao@microsoft.com>
Why I did it
This PR aims to fix the Monit issue which shows Monit can't reset its counter when monitoring memory usage of telemetry container.
Specifically the Monit configuration file related to monitoring memory usage of telemetry container is as following:
check program container_memory_telemetry with path "/usr/bin/memory_checker telemetry 419430400"
if status == 3 for 10 times within 20 cycles then exec "/usr/bin/restart_service telemetry"
If memory usage of telemetry container is larger than 400MB for 10 times within 20 cycles (minutes), then it will be restarted.
Recently we observed, after telemetry container was restarted, its memory usage continuously increased from 400MB to 11GB within 1 hour, but it was not restarted anymore during this 1 hour sliding window.
The reason is Monit can't reset its counter to count again and Monit can reset its counter if and only if the status of monitored service was changed from Status failed to Status ok. However, during this 1 hour sliding window, the status of monitored service was not changed from Status failed to Status ok.
Currently for each service monitored by Monit, there will be an entry showing the monitoring status, monitoring mode etc. For example, the following output from command sudo monit status shows the status of monitored service to monitor memory usage of telemetry:
Program 'container_memory_telemetry'
status Status ok
monitoring status Monitored
monitoring mode active
on reboot start
last exit value 0
last output -
data collected Sat, 19 Mar 2022 19:56:26
Every 1 minute, Monit will run the script to check the memory usage of telemetry and update the counter if memory usage is larger than 400MB. If Monit checked the counter and found memory usage of telemetry is larger than 400MB for 10 times
within 20 minutes, then telemetry container was restarted. Following is an example status of monitored service:
Program 'container_memory_telemetry'
status Status failed
monitoring status Monitored
monitoring mode active
on reboot start
last exit value 0
last output -
data collected Tue, 01 Feb 2022 22:52:55
After telemetry container was restarted. we found memory usage of telemetry increased rapidly from around 100MB to more than 400MB during 1 minute and status of monitored service did not have a chance to be changed from Status failed to Status ok.
How I did it
In order to provide a workaround for this issue, Monit recently introduced another syntax format repeat every <n> cycles related to exec. This new syntax format will enable Monit repeat executing the background script if the error persists for a given number of cycles.
How to verify it
I verified this change on lab device str-s6000-acs-12. Another pytest PR (Azure/sonic-mgmt#5492) is submitted in sonic-mgmt repo for review.

[Monit] Deprecate the feature of monitoring the critical processes by Monit (#7676)
Signed-off-by: Yong Zhao yozhao@microsoft.com Why I did it Currently we leveraged the Supervisor to monitor the running status of critical processes in each container and it is more reliable and flexible than doing the monitoring by Monit. So we removed the functionality of monitoring the critical processes by Monit. How I did it I removed the script process_checker and corresponding Monit configuration entries of critical processes. How to verify it I verified this on the device str-7260cx3-acs-1. |

[Monit] Restart telemetry container if memory usage is beyond the threshold (#7645)
Signed-off-by: Yong Zhao yozhao@microsoft.com Why I did it This PR aims to monitor the memory usage of streaming telemetry container and restart streaming telemetry container if memory usage is larger than the pre-defined threshold. How I did it I borrowed the system tool Monit to run a script memory_checker which will periodically check the memory usage of streaming telemetry container. If the memory usage of telemetry container is larger than the pre-defined threshold for 10 times during 20 cycles, then an alerting message will be written into syslog and at the same time Monit will run the script restart_service to restart the streaming telemetry container. How to verify it I verified this implementation on device str-7260cx3-acs-1. |

[monit] Adding patch to enhance syslog error message generation for monit alert action when status is failed. (#5720)
Why/How I did: Make sure first error syslog is triggered based on FAULT TOLERANCE condition. Added support of repeat clause with alert action. This is used as trigger for generation of periodic syslog error messages if error is persistent Updated the monit conf files with repeat every x cycles for the alert action |

[monit]: monit_telemetry which will have error when telemetry is in secure mode (#4286)
When telemetry is in secure mode ,the monitor will have error log of the match string "--insecure". So I modify to be compatiable with insecure mode and secure mode. Co-authored-by: Ubuntu <ubuntu@ip-10-5-1-21.ap-south-1.compute.internal> |
