halfdanePresenting ilias, yet another dashboard because obviously the world needed one more
I’ve gone to write something almost exactly like this several times and never quite finished. I like how this is set up. It seems like one thing that could be improved is parameterizing the configs a bit so that e.g. matching a 200 status gives a standard label that doesn’t need added to every job
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!
Cool ❤
watsonJust FYI, Homepage has ping functionality to check if your services are up.
siteMonitor
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.
Its just an idea…
When my router says “threat” and gives me an IP address, this address gets added to a big ass database that all routers see. Then every router in the world blocks their ass out…get them to go to a government office and ID themselves as an adult if they want back in.
David J. Atkinson@altphoto @selfhosted This is essentially what Pi-Hole does. It handles your DNS queries and blocks any that you want. It automatically updates blocklists from a variety of sources available. Some IPs are trackers, advertisers, malware, phishing and other notorious or otherwise obnoxious. You decide. Works great. I have about 1.7 million IP addresses blocked, but only a couple thousand or so show up on any day. Amounts to between 5% and 8% of my total traffic. I cannot fully express my joy with the FREE software. I have a dedicated Raspberry Pi 4B on my network for this purpose, but it can run on almost any Linux variant. #RPi #homelab #DNS #PiHole
soo… servers your router doesn’t like for whatever reason blocked for everyone else? with gov ID checks? why would we want that?
and how is this a dashboard idea?

I’m sorry if this is a dumb question, I am on my phone and did not check much of the repo. I was thinking of adding a dashboard to my stack, and was thinking about Prometheus + grafana because of versatility but the main con is the complexity.
How are the graphs generated on your example? Are they static images generated manually?
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
