Mem stats not passed to Compose-plugin

lockerlab · Aug 10th 2024

Recently, I switched to OMV 7 and I'm very happy with all the enhancements and the stability of the system. The changes to Docker management are also great, namely going with a native plugin. Thank you!

One thing, that currently doesn't work though, is the memory stats in the Compose-plugin Stats section (see below). Is there any further setup needed to see how much memory my containers consume?

I'm running OMV7 on Raspberry Pi OS 64-bit. Reading the memory stats under Diagnostics -> Processes works as expected.

The processes tab is completely different (uses the output of top) than the docker stats command that plugin is running. The exact command it runs is:

docker stats --no-stream --format "{{.ID}},{{.Name}},{{.CPUPerc}},{{.MemUsage}},{{.MemPerc}},{{.NetIO}},{{.BlockIO}},{{.PIDs}}"

You could also try clicking the Clear cache button on the Settings tab since the stats tab is cached for speed.

Thanks for the hint! Googling docker stats-related problems led me to this solution:

Apparently /boot/firmware/cmdline.txt was missing the setting cgroup_enable=memory.

Now, memory usage shows up on the commandline and through the GUI

Good find lockerlab I very occasionally look at compose stats on my rpi and have thought something was wrong.

Applied this fix on a rpi4 and rpi5 - works great.
