checkmk VS postgres

Or Checkmk [1], which is coming from Nagios and brings thousands of plugins for nearly every hardware and service you can think of..

CheckMK - GitHub

CheckMK https://checkmk.com. You can spin this up in a docker container

I use CheckMK to do all of this and more, except nutanix. But checkmk also can Monitor nutanix via the "Nutanix Prism" special agent Integration

BI machine and NVR report to CheckMK Raw host so it's easy to see historic stats.

I’m using https://checkmk.com/ to monitor stuff and it seems to work great. Lots of built in features and functions and if they don’t have what you need you can also create custom scripts to check and report on anything you can dream up. Runs great in docker (I’m using portainer but will run fine in plain old docker).

Have a look at CheckMK open source version is really good, you can spin it up in a docker container and is relatively easy to get some initial monitors going. As to whether it's worthwhile, I guess it depends how much you want to know how you servers are doing and when something goes wrong.

EDIT: Somehow i managed to fix it right now (I struggled with this problem yesterday for hours). This github issue have helped: https://github.com/docker-library/postgres/issues/537 If anyone runs into this problem, those are crucial instructions that helped me: docker system prune docker-compose up --force-recreate --build --remove-orphans --always-recreate-deps --renew-anon-volumes

Tragedy of the commons - only need a few actors to ruin it all for us. Almost all distributors face this problem, from Docker Hub to PyPI. This also reminded me of official Postgres Docker image running a cryptominer in the background [1]

If you open the dockerfile of the desired container, you can determine exactly how and what was built. If not satisfied, you can always build your own container with the right postgresql build flags.

Ok according to The Dockerfile, postgres is running in /var/lib/postgresql/data so you will need enter the container and look at the log files in /var/lib/postgresql/data/pg_log/

I got started on trying to make a basic postgres image but I can't seem to figure out how to include a shell script in the same folder as my nix file (fetched from https://github.com/docker-library/postgres/blob/master/docker-entrypoint.sh and to be modified once I get it working) into the docker image as an entrypoint

See example here : https://github.com/docker-library/postgres/issues/601
