I FINALLY figured out how to drive the Grafana bus. I know, I know...pretty basic stuff. In the past I always drooled over dialed out dashboards I've seen. Charts, graphs, readouts, dials...but I never could quite wrap my head around it all.

Well, now I have charts, graphs, readouts, logs, dials, and it feels pretty good to have finally learned something new that I've been whacking away at for a while. The plus side is that the whole Graphana+Promtail+Loki stack sips lightly on my resources, whereas in the past, things like the ELK stack, Opensearch, Graylog, etc, really devoured a lot of resources. I really tried with those but just didn't like how ravenous of a RAM appetite they had.

I'm still using lnav. It's quick and dirty and gets the job done for logs. But if I want to look at data, with nice a prettyfied interface, I go look at Grafana. So now the process will be to, dial out and graph every last little thing until I suffer from info overload, and then ease it back to just what is necessary. It's a fucked up process, but it's how I do.

As my lady friend is apt to say: It's the little things.....

ETA: I have cAdvisor rockin' plus influxDB, and the the thing is only sipping like max 2 GB. I've got logs, dials, charts n' graphs. I got bitches in the living room gettin' it on....This is amazing for such little processing power.

I have a follow up question about cadvisor, if you have a minute. Cadvisor employ Redis and Prometheus. If I understand correctly, you configure Prometheus to scrape Docker logs. All fine and good. However, my Grafana stack already employs Prometheus to do the same, just for syslogs and such, but not Docker. Can I not place the contents of the Cadvisor/Prometheus config in the existing Prometheus implementation used with Grafana, or does Cadvisor need it's own Prometheus instance.

You should be able to just add a scrape config to your existing deployment of prometheus

Thank you for the reply. I guess I am thinking, why have multiple Prometheus instances running, eating up resources, when I could do it with just one.

Sorry I didn’t get back to you right away. But this is correct. I just have Prometheus scrape cAdvisor.

[–] irmadlad@lemmy.world 2 points 7 hours ago

You're fine. Thanks for the follow up.

[–] __init__@programming.dev 2 points 8 hours ago (1 children)

For sure. Simplifies querying the data too, since you won’t need to deal with multiple data sources in grafana.

Awesome!
