Metrics? eg CPU & memory usage per app about piku HOT 5 CLOSED

Hi! Yeah, enabling Discussions seems like a good idea. At least it's more searchable than Discord :)

There is no built-in way to have CPU and history per app - yet. both @chr15m and myself have taken a few stabs at this in the past (I have a little monitor app that looks at process names and CPU counters, but never cleaned it up for publishing), but most of the time it just doesn't add a lot of value when you're running on small machines.

As to usage quotas, I have been looking at using cgroups for that, but it requires a lot more moving parts (I have an experimental setup here that I have been playing with). But, again, most of the time it just isn't necessary unless you have something that does a lot of batch processing and hogs the machine.

Thank you! I'll leave the request open for metrics, especially since there were some attempts.

@mariusa I built this little hack which just measures CPU every minute and if it is higher than threshold takes a lot of all running processes. It's generally enough to determine which app is eating the CPU: https://github.com/piku/piku-monitoring

Nice, I'll try it out after managing to setup piku. Thanks!

FYI see also https://github.com/Unitech/pm2
but I see that has 700 issues, including Unitech/pm2#5559
Seems like they want to push their own proprietary & centralized system through this tool.

Also moving this to discussions for archival purposes (follow ups can go there)
