I'm with Robert - simple and good enough is often better than perfect but
unfathomable. Consider how likely it is that you would care about a
filesystem mounted under /tmp to be full.
Here's a slightly more accurate match, but still very simple:
DISK %^/tmp/\{.*\} IGNORE
This will match any string in the form {*}.
Another option is to add "delayred=disk:5" into the hosts.cfg entry for the
hosts that get the local backups. This will delay the alert long enough for
the filesystem to be un-mounted. However, there's a risk that a genuine
alert for another filesystem is delayed by 5 minutes.

Hello Robert,
If you do not expect to mount something else in /tmp, you may use
something like:
DISK %^/tmp/.* IGNORE
seems easier to read and understand, however may be too wide.
If you expect to mount something else in /tmp, then your regex seems OK
and unavoidable
Le 08/02/2021 ? 16:38, Robert Herron a ?crit :
I'm deploying Veeam Backup & Replication to perform systems. I have a few
Linux hosts that require being backed up via the local agent instead of
using a VM-based backup. The backups run in the middle of the night as
you might expect. 2AM Sunday, I received a full filesystem alarm on a
Linux host I'm testing. It cleared in the next test sweep 5 minutes later
but the unnecessarily alarms woke me up. I want to minimize that from
happening.
The Veeam agent creates and mounts devices under /tmp for the backup. The
df line from the filesystem alarm looks like:
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/veeamimage7 4128448 4026052 0 100%
/tmp/{16296b8b-8ad4-6614-6da9-aacdc519bd6b}
The actual filesystem name is different on each host. I assume it's based
on the host's BIOS UUID or the block ID. I don't want to add individual
lines for each host.
I want to add the following line to my analysis.cfg in the "CLASS=linux"
section:
DISK
%^/tmp/\{[A-Fa-f0-9]{8}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{12}\}
IGNORE
Questions:
1.) Is this regex valid for the analysis.cfg?
2.) Is there a better way to handle this?
Thanks,
--Robert.
