Missing Disk IO graph on a specific LXC

[krikey]

I have a few LXCs running on a PVE 6.4-14 server. Three of them render the Disk IO graph ok in the Summary tab but one of them shows no Disk IO at all in the past hour which is very odd as this server is quite busy. The only main difference between them is the LXC with the missing Disk IO has a second mount point, where the others don't (see screenshot)

That problem exists for atleast months. Also got two of my 4 LXCs without Disk IO graphs. I think your mp0 isn't the problem, because here I also got LXC without the graph that use no addition mount points.

I also have the same problem. None of my LXC's show anything but zeros. The same containers do show CPU usage, Memory usage, and Network traffic so monitoring is generally working and enabled.

All the VM's, on the other hand, shows the Disk IO properly (along withe CPU, Memory and Network).

Some of the LXC's have mount points, some don't, so that is not the problem either (i.e. simply confirming what @Dunuin said above).

I'm currently experiencing this on 7.4-16.

This happens even when I 100% know Disk IO must be > 0 as it is currently doing a data-intensive disk task below.
