How to monitor TrueNas Scale disks

[nodesocket]

I installed the Beszel agent via container using TrueNAS apps. Everything is working, except for disk usage.

I tried setting the envar:

FILESYSTEM=/dev/sda,/dev/sdc,/dev/sdd,/dev/sde,/dev/sdf,/dev/sdg

But no luck. Any ideas?

truenas_admin@TrueNAS[~]$ lsblk

Do you want to add them together to count as your 'root' disk?

Or are you trying to just get them to display individually on the system details page?

[nodesocket]

Either? 😀 I also tried adding the ZFS mounts to FILESYSTEM=/dev/pool,/dev/pool/ai

And nothing, on beszel-agent startup says not found.

Try setting LOG_LEVEL=debug and check what it outputs for partitions. If this is a container then you'd need to mount directories from the other partitions in /extra-filesystems.

There are some known issues with ZFS that I'm planning to sort out in one of the next few minor releases. See #200 for more info.

Yup, it's running in a container inside of TrueNAS. Can you give more insights on how to mount directories from other partitions in /extra-filesystems?

Currently the Beszel-Agent only sees the local agent docker volume, which makes sense.
