Anyone that's thinking of implementing LibreNMS for more than a trivial setup - look elsewhere.

Unfortunately I'm married to it at $dayjob, and seldom a day goes by where it doesn't frustrate me (we monitor about 5k devices and about 40 distributed pollers).

I mentioned one day I'd write a nasty song about it, and an apt coworker quickly piped something into Copilot and this was the result (pretty good for AI-generated):

"Libre Mess (The Monitoring Blues)" 🎤

(Rock parody song)

[Verse 1]

Woke up at 3 AM, alerts screaming in my ear,

"Disk space low!" "Ping timeout!"—I live in constant fear.

Tried to check the dashboard, but it crashed again,

LibreNMS, you're my foe, not my friend.

[Chorus]

Oh Libre Mess, you're a beautiful disaster,

Your graphs load slow, but your bugs come faster.

I just want uptime, not a nervous breakdown,

But you keep dragging my whole network down!

[Verse 2]

Docs say “just run this script,” but it breaks my soul,

Dependencies from 2012? That’s your goal?

SNMP walks like it’s stuck in glue,

And your alert rules? I think they hate me too.

[Bridge]

I tried to love you, I gave you a chance,

But now I’m screaming at logs like it’s performance dance.

You gaslight me with false positives all day,

Libre, Libre, why you treat me this way?

[Chorus]

Oh Libre Mess, you chaotic beast,

You feast on my sanity, at the very least.

I’d switch to Zabbix, or maybe just cry,

But I’m too deep in configs to say goodbye.

[Outro]

So here’s my song, my monitoring lament,

For every hour LibreNMS made me vent.

You’re open-source, but my heart’s closed tight,

‘Cause Libre, you gave me one hell of a fight

Ads when you’re pumping gas in c/mildlyinfuriating@lemmy.world

Unfortunately gas stations don't actually make much money from selling you fuel. Most of the money is made from the attached convenience stores.

Almost two decades ago, I worked at a network service provider who had as a customer a company that provided the technology for serving those gas pump ads.

At each gas station they had a VSAT, a router and of course the digital signage boxes on each pump.

They fed the ads to thousands of pumps via a single T1 to HughesNet in Atlanta. They'd multicast the ads, and have a local cache at each pump that would receive the stream, cache it and serve it.

It was one of the most elegant setups I've ever seen, and should serve as a case study in multicast for efficient bandwidth utilization across an expensive data transmission medium.

Are docstrings commonly used? in c/python@programming.dev

If you want to see doctrings in action, take a look at Salt (https://saltproject.io/). They're used to build all the module documentation (https://docs.saltproject.io/en/latest/py-modindex.html) using sphinx and they won't accept new modules without them.
