Instead of all of these sed and echo commands, wouldn't it be cleaner to keep our own custom monitrc file in this directory and just copy it into /etc/monit/ here instead? #Resolved

Technically they are the same. The benefit of sed is reusing the default config, and easy to detect incompatibility issue in future monit config (which may be rare but possible).

I do agree that it would be easier to detect future compatibility issues.

can we also add cpu and mem utilization alert? |
|
we also need to add cpu and mem util too, maybe it also make sense to add it into the base image so that we can monitor some process in the base image too. |

merge the sed RUNs to -ri with one docker command to make it clear. (like https://github.com/Azure/sonic-buildimage/blob/master/dockers/docker-database/Dockerfile.j2)

Personally, I think the separate RUN commands are pretty clear, plus there's no need to escape every line break.

i think it is better to put monit into pmon docker as the name of the docker implies. |

@stcheng, you cannot monitor the base image process such as ntp, sshd when monit is in pmon |
|
@stcheng @lguohan: Acually, installing monit in the base image makes more sense than in docker-platform-monitor. Correct me if I'm wrong, but my understanding is that docker-platform-monitor's purpose is for monitoring platform-specific hardware, whereas monit is being used to monitor the state of the OS. Thought of this way, monit actually belongs in the base OS, not in docker-platform-monitor. |
This reverts commit 9cbbf591c08bce4b52a0f68cbbddae102d7fc614.

It enables cli to check status. The access is granted to local connection, so it should be safe.
