[CollEc] Monit

[Düben, Christian]

Hi,

I noticed this morning that CollEc's MariaDB had been down for five days. Consequently, the app did not produce any results during that time.

It looks like the entire system took a hit five days ago. Usually, that is not a problem. The Docker containers are set to restart automatically. While the ShinyProxy container did restart, the MariaDB container was damaged to an extent that Docker could not restart it.

Large organizations construct their IT infrastructure based on Docker. So the system is built to be robust and it takes serious events in the host system to cause critical errors preventing automatic restarts. And even when that happens, I can usually set it up again with a few lines of code. To do that, I have to notice that something is wrong in the first place.

As I only check CollEc infrequently these days, I would like set up a notification system that sends an e-mail alert following critical errors. In particular, I would like to use the system outlined in this post: https://dummylabs.com/post/2018-08-15-monit/. It uses Monit to send e-mail alerts. Monit needs to be connected to an e-mail account / mail server. Is there a mail server on Helos that I can connect it to?

Kind regards,
Christian
