strange behavior of pvestatd+influxdb

[Hilario Ortigosa]

Hello, I'm adding pvestatd's stats into influxdb+grafana. status.cfg works with influxdb config with no problem, but I have several partial behaviors depending on (I guess) kernel version. With last version (4.4.49-1-pve) I have no diskio stats, and with previous 4.4.XX versions I have no stats, or (with 4.4.21-1) I have full network+cpu+mem+diskio stats. I can see the same behavior at infxludb and Proxmox GUI, so I guess it's related with kernel giving partial (or not al all) info to pvestatd.

All PVE runs LXC, none of them are clustered, and I've tried more than 5 different servers with different kernel versions. status.cfg is configured as wiki said and it reachs influxdb (I can see the hostname as a new tag for selecting in dashboard)

There is additional config needed in recent versions for this ?

the disk I/O stats seem to be broken in general at the moment - could you file a bug report at bugzilla.proxmox.com? I suspect the other issues with previous versions were fallout from the move to a cgroup sub-hierarchy.
