I have a Raspberry Pi running Docker and a number of containers. I plan on adding another Pi soon. Curious what folks are using for a dashboard to monitor performance of all your hosts and containers. I was thinking of deploying Grafana for this but am curious what others use.
Zabbix
I second this. I just set my instance up a couple weeks ago.
While researching, I saw many people saying that it’s very good but is hard to set up. I disagree with that to some degree; Setup itself is extremely easy, configuring it the way you want isn’t as easy BUT is wayyy more time consuming. Time consuming != hard, though. Just take time to tweak it how you want.
Well, I run my containers in kubernetes.
And, it more or less includes full support for prometheus/grafana/alertmanager/etc.
So- I use that.
I have questions about this. I’ll be getting another Pi or two and was considering putting k8s on them. Would I be able to set them up with kubernetes and then import my existing Docker containers from my current Pi to them?
Yup. You can do that.
Although- you wouldn’t “import” your existing containers. but, you can…
- Create manifests for your containers (Kubernetes runs the exact same docker containers). or, find helm charts for your containers.
- Import the storage from docker into your new PV/PVCs.
I would, suggest learning kubernetes first though. Learning curve can be rather steep.
Also, rancher + k3s would work perfect for your Pis.

Does overspeccing your hardware so much performance issues never come up count?
For normal people grafana & prometheus are typical good answers.
I really enjoy practicing with Datadog - though it gets quite expensive really quickly and is quite overkill for 6-7 hosts, many VMs, and 20ish containers.
We use it at work, but monitoring isn’t my team’s responsibility so I try to understand how it all fits together by practicing with it at home.
I think Datadog should have a homelabber tier (above the free 5 physical hosts) that allows people to tinker. I honestly think it would net them more customers.
