No show disk space usage

[alb73]

i am using zabbix server 6.2 and zabbix agent 6.0 on servers.

For all Linux servers I use the "Linux by Zabbix agent" template

The problem is that for some servers the chart on free disk space is not displayed. That is, there is no such indicator.

I saw that the problem is for Centos, here are several versions of different servers without such a metric

CentOS Linux release 7.7.1908 (Core)
CentOS Linux release 7.6.1810 (Core)
CentOS Linux release 7.2.1511 (Core)
CentOS Linux release 7.9.2009 (Core)

In total, I have such servers without this metric 62 out of 250

How can this be fixed?

Based on https://www.zabbix.com/integrations/linux
There is no "free space" item at all...

Filesystems	{#FSNAME}: Used space	Used storage expressed in Bytes	ZABBIX_PASSIVE	vfs.fs.size[{#FSNAME},used]
Filesystems	{#FSNAME}: Total space	The total space expressed in Bytes.	ZABBIX_PASSIVE	vfs.fs.size[{#FSNAME},total]
Filesystems	{#FSNAME}: Space utilization	The space utilization expressed in % for {#FSNAME}.	ZABBIX_PASSIVE	vfs.fs.size[{#FSNAME},pused]
Filesystems	{#FSNAME}: Free inodes in %	-	ZABBIX_PASSIVE	vfs.fs.inode[{#FSNAME},pfree]

Can you please share the item config, what you have there, what seems to be missing on some hosts...

My problem: I don't see Item: "filesystem" for this servers.

On list items missing "Mounted filesystem discovery"

Discovery rules "Linux by Zabbix agent: Get filesystems: Mounted filesystem discovery" is listed on both servers.

and status "Enable". Rule is standard.

"Regular expressions" - File systems for discovery - standard - ^(btrfs|ext2|ext3|ext4|reiser|xfs|ffs|ufs|jfs|jfs2 |vxfs|hfs|apfs|refs|ntfs|fat32|zfs)$

server without "filesystem" in zabbix:
df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/vda1 ext4 99G 92G 1.6G 99% /
tmpfs tmpfs 246M 0 246M 0% /dev/shm

severt with "filesystem" in zabbix:
devtmpfs devtmpfs 5.8G 0 5.8G 0% /dev
tmpfs tmpfs 5.8G 0 5.8G 0% /dev/shm
/dev/vda1 ext4 178G 161G 7.6G 96% /
tmpfs tmpfs 1.2G 0 1.2G 0% /run/user/0

what could be the problem? Help me please

hey alb73 did you ever work this out? I'm having the same thing with 7.0 LTS

I've added 2 Linux hosts and 1 Windows box to be monitored via SNMP, on the Windows machine I see the disks and their capacity being monitored, but in the Linux area this "FS [{#FSNAME}]: Space utilization chart (relative to total)" us just blank.

Disk monitoring via SNMP is working as I can see them in my PRTG instance. Any pointers? I've tried "Generic by SNMP" and "Linux by SNMP" templates and no joy.

Hey,
can you check what you're getting after running this on your zabbix server instance?
zabbix_get -s (IP-or-Hostname-of-problematic-host) -p (port-number) -k "vfs.fs.get"
in that way you can check if your Zabbix is able to read details of filesystems on that host.

found my solution I had to add the following lines into my snmpd.conf file

# Specifically monitor the root directory
disk /
disk /mnt/usb

then they would be seen in zabbix... strange why I didn't have to have them in PRTG for it to work.
