NewRelic no longer offers server monitoring for free accounts, so what are the alternatives when you’re on a skin-flint budget?
There are lots, but I’m not going to review any of them. Instead, I’ve been tasked with getting Amon running on a DigitalOcean droplet so that it might be appraised.
Amon can either be used as a SAAS, hosted by Amon themselves. Or it can be run “On-Premise” by cloning the git repo to your own server.
The On-Premise instructions didn’t work for me as-is on a fresh Ubuntu 16.04 server. So I present to you here the result of getting it going!
Assumptions:
- You know what you’re doing with Linux on a server.
- You can create your own VPS, or have dedicated hardware, that will only be used for server monitoring.
- MongoDB is installed from Mongo’s repo, not Ubuntu’s.
- Let’s Encrypt is used for the SSL certificate.
- The FQDN used for accessing the Amon instance matches the server’s full hostname (easy enough to change by altering FULL_HOSTNAME).
- Postfix is used on localhost as the MTA (alter the content of /etc/opt/amon/amon.yml if that’s not to be the case).
The following took the instructions of https://docs.amon.cx/onpremise/ and then extended/tweaked them to create a fully working server.
So the initial script I wrote turned out better suited to being a collection of scripts. And to keep them together, I’ve created a new GitHub repo to house them.
If you find it useful, great! If you would like to help make the installation provisioning system better, PRs are very welcome 🙂
I followed the official setup guide and stumbled over this blog article while searching for a solution to the following things:
– I’m receiving nginx 500 errors when trying to test email sending. (localhost postfix)
– Resetting pause of alerts doesn’t work properly either.
– I could not figure out how to monitor ZFS volume pools
Any ideas?
Thank you for the scripts. I have a problem during amon installation and see if you could help. Everything install well until the line “python manage.py migrate” in the amon.sh. Any idea? Thanks in advance.

After googling for some time, my problem is solved. As of today, after installation using the above script, you will be facing issues 211 (https://github.com/amonapp/amon/issues/211) and then follow slava-vishnyakov commented on Apr 19. Thank you the script.
One more big thanks to you. I write up a step guide from my installation experience. https://github.com/moonbury/amon-onpremise-installation/blob/master/README.md
Great! Glad it has been of use to you 🙂
