I love grafana, but it’s a resource hog, and my machine isn’t powerful. Prometheus/node_exporter however is as lightweight as it can get.

So I made a little Python script that fetches the data from Prometheus and uses mathplotlib to generate a graph.

The dashboard calls that python script for every configured graph and embeds the image so it looks nice.

You can find the script in one of my other repos (Prometheus-renderer probably), but there are dozen similar ones: search github for Prometheus renderer and you’ll see

If there are other things unclear, please don’t hesitate to ask

Wow, I can really see this taking off in the international dashboading-scene!

Is it … a new tool? I love new tools 🥹
⁨Comment⁩ on ⁨Presenting ilias, yet another dashboard because obviously the world needed one more⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
Couldn’t stop worrying about this, so I added: - --no-tooltips param: Don’t include check output for hover tooltips - --no-timestamp param: Omit the “Generated at” timestamp to hide system clock and monitoring cadence.

If you’re using these, I feel much better about making the html publicly accessible, but when you set up a config please remember that links-tags can expose your internal topology and the tile/slot name might do the same! Don’t go naming your tiles something like “Database Primary”, “Payment Service Worker”, or “Internal Auth API”!

(unless you wanna place a honeypot)

Well, Ilias can certainly fill this niche. With a caveat:

Currently all output from checks are accessible as tooltips (so they’re in the HTML source), but for usecases such as yours it might be helpful to have the ability to suppress that kind of information leakage.

I think I’ll implement that in the coming days …

⁨Comment⁩ on ⁨Presenting ilias, yet another dashboard because obviously the world needed one more⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

Loved that idea so much that I went and implemented it: - The checks now have an automatic type inferrence and shorthand - introduced default rules that are used when nothing’s configured - realized that yaml-anchors always worked thanks to the lib I’m using.

So now with this preamble:

# Defaults are used when nothing is defined at the slot level. They can be overridden by defining rules directly on a slot.
defaults:
  rules:
    - match:
        code: 0
      status: { id: ok, label: "✅" }
    - match: {}
      status: { id: error, label: "❌" }

# YAML anchors: reusable fragments ilias doesn't interpret directly... 
# it's all just yaml
_anchors:
  pct_rules: &pct_rules           # works for disk, memory, CPU …
    - match:
        output: "^[0-6]\\d%$|^[0-9]%$"
      status: { id: ok, label: "✅ <70%" }
    - match:
        output: "^[7-8]\\d%$"
      status: { id: warn, label: "⚠️ 70–89%" }
    - match: {}
      status: { id: critical, label: "🔴 ≥90%" }

I can now have a tile like this:

      - name: Memory
        slots: # combine anchors and default rules as well as check shorthands
          - name: usage
            check: "free | awk '/^Mem:/ {printf \"%.0f%\", $3/$2 * 100}'"
            rules: *pct_rules
          - name: available
            check: "free -h | awk '/^Mem:/ {print $7 \" free\"}'"
            # uses default rules
          - name: total
            check: "free -h | awk '/^Mem:/ {print $2 \" total\"}'"
            # uses default rules

And the best? It’s fully backwards compatible ❤️

Thanks again for the suggestion!

Yes, I’m aware of that, but I always found it weird to have a live service for something that hardly ever changes. And then I had the idea of this whole “fully self contained html”, and now I can’t imagine it another way 😆

That’s just opinions though, and if Homepage strikes your fancy go for it - it’s an awesome project.

Hu, never thought of that - that’s a pretty neat idea! Thank you 🤗
⁨Comment⁩ on ⁨Presenting ilias, yet another dashboard because obviously the world needed one more⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
Awesome, thanks for the consideration!

Please don’t immediately start public facing however - I literally just bashed the thing together in an afternoon, so who knows what kind of exploitable information leaks it might bring!

I’m personally using it from within a tailnet, so not public facing.

Interesting, I attributed it to the data not being completely up-to-date before. And my upvote made the server do some syncing, so more current information is available
