BLUF: Is there a “datadog-for-home”?
I’ve a ton of stuff running at home ranging from a 5-node PI cluster with various containers running on them including things like self-written python scripts doing “super important” stuff, node-red running everything about my energy setup, pfsense, TrueNAS etc.
Logging is painful and I’ve just lost about 4 hours trying to find a fault which stopped car charging. Lots of rabbit holes were entered as I currently don’t have an end-to-end logging solution.
What does everyone else use?
You must log in or register to comment.
Dozzle may be a bit basic for your needs, but it could be one tool in your toolbox.
You can also view application logs with Dozzle in addition to container logs.
Opted for loki since it allows using the same interface for multiple purposes
Depending on your existing monitoring stack, some options might be:
- Grafana Loki
- Sentry can be self-hosted for application logging
- Logstash is self-explanatory, use with other parts of Elastic’s software like Kibana for visualization.
Anyone here got a solution working in Unraid? I looked into this recently but got a bit stuck.
ELK
Loki to Grafana.
I like Grafana/Loki/promtail etc.
But Datalust Seq is also nice.
Graylog can do a lot but its too bloated and too hungry for my taste (damn elasticsearch).
A simple syslog server is ready.
Look into ELK stack. I personally hate it but if you can learn it there’s a chance you can build a career on it.
I come from a Cybersecurity background which might explain my answer: Security Onion had proven adept at cross referencing logs and pcaps which is pretty awesome for troubleshooting
And +1 for Dozzle to see real-time Docker logs.
For most self hosted use cases Splunk’s free 500MB (per day) license should be enough. It’s way easier to set up and maintain than ELK and has tons of free extensions for parsing log formats and dashboards.
I considered it, seems nice.
Problem is that they recommend a 12 physical cores and 12GB which is a waste for the usual selfhosted lab.
I ran it on a VM with 2 cores tops and a couple of GB of RAM for about 50MB of logs per day.
Also using Graylog, dead simple to set up with rsyslog and at work we even use the sidecar for window logs.
Splunk
Anyone else looking at openobserve. Looks OK for homelab, but not really stable
What do you mean by not stable? It’s in use in production by hundreds of organizations.
They state in their documentation that the software is alpha (https://openobserve.ai/docs/ OpenObserve is currently in alpha, but don’t let that stop you from trying it out.) . To be honest I didn’t bother to investigate why ingesting data stops working after a few days, might be my installation then.
I’m very curious which organisation uses alpha software in production
https://github.com/openobserve/openobserve . Built in rust - No JVM. Much lighter than the alternatives mentioned here and with extremely good UI. Beautiful dashboards. Could even run on raspberry pi.
Graylog
