Observium has been on my to-do list since this 2023 article brought it to my attention.
It has a great community edition we can self install. It’s open-source but the docs all speak of ‘svn’ and the mirrors I find on Github are forked over (e.g. here) so it could just be subversion
Today we’ll set it up on an Ubuntu host as well as Docker with a real MariaDB backend and lastly with Docker-compose. We may even get into a little ansible to spin up SNMPD on Linux hosts.
Let’s get started!
Observium Install
The Community edition will install a local MySQL

Installing systemd unix-agent service...
Created symlink /etc/systemd/system/sockets.target.wants/observium_agent.socket → /etc/systemd/system/observium_agent.socket.
DONE! UNIX-agent is installed and this server is now monitored by Observium
[*] Installation finished! Use your webbrowser and login to the web interface with the account you just created and add your first device
I could now go to http on the server to see the Web UI
And explore the landing page
After a while I could see some details like Core temps, storage and event logs
The graphs are fantastic. For instance, I can easily break down memory usage over time
The overview is almost too much information to take in at once
Docker
I’m not entirely keen on running this as a fat app with database on a touchy old Macbook Air.
Someone has made a Github repo with a Docker container for running either with Docker Compose or as an App.
Since this uses MariaDB 10, we are in luck (as that is what is on the NAS).

I’ll make some folders on my docker host
builder@builder-T100:~$ mkdir observium
builder@builder-T100:~$ mkdir observium/logs
builder@builder-T100:~$ mkdir observium/rrd
Then launch
$ docker run --name observiumapp \

I’ll first try by adding my Dockerhost (on which this container runs)
Did not seem to like that (same with 192.168.1.100)
Perhaps we need to install the base snmpd agent on the host

If you know me, then you know if I have to do something more than once, dammit, I’ll make a script or playbook.
So I created a new Ansible Playbook you are welcome to take/use.

pass_persist .1.3.6.1.2.1.31.1.1.1.18 /usr/local/bin/ifAlias_persist
I can now add to AWX
To test, I’ll just run on one host
The job completed
I then went to add “AnnaMacbook” by IP
But it just seemed to hang in Docker
I tried from the physical instance of Observium and it worked (note: .13 and .81 are the same host in my network)
Which we can see
I’m going to try bouncing our Docker instance - perhaps it’s just stuck
builder@builder-T100:~$ docker ps | grep observ
2ed622e9887a mbixtech/observium "/usr/bin/supervisor…" 13 hours ago Up 12 hours 0.0.0.0:8078->80/tcp, :::8078->80/tcp observiumapp
builder@builder-T100:~$ docker stop observiumapp
observiumapp
builder@builder-T100:~$ docker start observiumapp
observiumapp
However it still hangs (we never see the green added). I even enabled and tried TCP and waited a full day to complete.
Could it be my NAS database?
I decided to stop and remove the containerized db
builder@builder-T100:~$ docker ps | head -n2

I’ll pull down the repo

I can login with the new password and see an empty system
We can then add it
And I can see it listed
I can add another without issue
I’ll now launch on the rest of the hosts then add to Observium
I can see details for the new hosts
I tried setting up SMTP settings
Then an email contact
Then associate with my contact
However, even waiting a full day, i never saw any alerts trigger. I also set a log alert for “.*” and did not see that trigger
Perhaps it’s just that I don’t quite understand the alerting system - I’ll own that. But without a test and without some kind of clear schedule, I have no idea if notifications would even work.
Quick side note, I found the Entities global setting would let me switch to Fahrenheit
On times
I watched the data for a day
What really confuses me is that the date picker clearly knows my TZ (it is around 6a now so that looks right). But the graph labels wedenesday 6, 9 .. even if 9am that doesnt make any sense as its 6am Wednesday right now and i know we get some spikes around 1 to 3 am
I have to assume that graph is in UTC which would make “Wed 09:00” about Wed 4am CDT (local).
Upgrades
As we saw from the banner
there is a new version from the one I’m running (21.10)
builder@builder-T100:~/docker-observium$ cat docker-compose.yml

I believe we just need to use docker to turn off our system, update the label and docker compose to bring it back up.

Note: we can also go to Dockerhub and see releses there
As well as their Github Releases.
However, on boot up, I could not log in, my admin password kept getting rejected…
I even went into the container to add a new admin user (level 10)
builder@builder-T100:~/docker-observium$ docker exec -it observium-app-1 /bin/sh
# cd /opt/observium
# ./adduser.php admin2 P4ssw0rd8888 10
Observium CE 23.9.13005
Add User
User admin2 added successfully.
#
But that failed
FIXED!
One needs to fire off the Database migrations manually after upgrading the app image…
builder@builder-T100:~/docker-observium$ docker exec -it observium-app-1 /bin/sh
# /opt/observium/discovery.php -u

Once I did that, I could log back in
And more importantly, I saw that the bug that annoyed me about UTC times in graphs was fixed!
The new release has a few more features I didn’t notice before like Graphs on polling
and refresh intervals if it was to be in a NOC or as a persistent dashboard
Costs
The version we have been using, the “Community Edition” is free. The have a Professional and Enterprise which frankly are ridiculously cheap, in my opinion
The Team page shows it’s basically a three man operation with the founder Adam Armstrong (and company registered) in the UK.
The company has been around for over 12 years and seems to do it’s one thing well.
It’s rather refreshing to see a CEO who tags himself in LI as “Accidental Founder, Reluctant CEO and Haphazard Investor.” and they just keep on with one solid, albeit older, product.
Summary
Overall, I like Observium. It’s an older PHP app but has some good graphing and monitors as fetched by way of SNMPD
I’m torn on whether it’s better than the tried and true Zabbix which I covered in a two part series last year, “Zabbix: Part 1: Introduction and Setup” and “Zabbix: Part 2: Configuration and Usage”.
While I could expose this with a TLS ingress, it seems like the kind of app better kept behind the firewall of my network.
I can also use my Obsidian linuxserver shell to front into Observium and avoiding having to setup a persistent Observium ingress.
Also, I made a couple of tweaks to the Playbook for restarts, so feel free to take a copy of the Ansible playbook and Jinja SNMPD conf File
