vfs.fs.size - show with volume is free space 0

[najkon]

Hi,
i just looking solutions for trigger which will show on with volume free space is now 0 in %
I have lot of LVM volume and i want to know on what volume space it's already full

Standard rule like vfs.fs.size[/,free] - it is a nuisance adding each mount point separately

like:
- vfs.fs.size[/a,free]
- vfs.fs.size[/b,free]
- vfs.fs.size[/c,free]

It's a way to do it in a more convenient way for zabbix and human?
I do not know, for example:

~ df -m
Filesystem                       Size  Used Avail Use% Mounted on
/dev/mapper/vg0-log             945M  885M     0 100% /var/log
/dev/mapper/vg1-log2            945M  885M     0 100% /mnt/log2
/dev/mapper/vg3-log3            1945M  885M  1000 50% /mnt/log2
[......]

df -m |grep vg |awk '$4==0 {print $1 " - free space 0%"}'

/dev/mapper/vg0-log - free space 0%
/dev/mapper/vg1-log - free space 0%

Have you tried using the default linux template?

For me it creates at least the following trigger:

Mounted filesystem discovery: Free disk space is less than 20% on volume /

and for all other mounted filesystems [as per the restrictions defined on the discovery rule]. You could easily tweak the default 20% threshold down to 0% if you wanted [or copy it].

To be clear, % free is monitored with 'pfree' parameter not 'free', ie:

{hostname:vfs.fs.size[/,pfree].last(0)}<20

To be clear, % free is monitored with 'pfree' parameter not 'free', ie:

{hostname:vfs.fs.size[/,pfree].last(0)}<20

Yes, sure - i know it.. about 'pfree' but that solution is still looking on ' / ' if % free space smaller that 20 - show it - right?

so what if We have one host e.g - Clound.localhost and there is 20 volumen all with different mounted point - how monitor each one individually if it decreases space (for example below 20%) or is equal to 0

add to the rule each time if a new volume appears

{hostname:vfs.fs.size[/volume1,pfree].last(0)}<20
{hostname:vfs.fs.size[/volume2,pfree].last(0)}<20
{hostname:vfs.fs.size[/volume3,pfree].last(0)}<20

?

not necessary.

in filesystem discovery,
items prototype : vfs.fs.size[{#FSNAME},pfree]
Trigger prototype : vfs.fs.size[{#FSNAME},pfree].last(0)}<10

it automatically pulls the available volume and will create trigger for each of them.
