How to monitor Use% of mount disk (Linux) on Zabbix

[tbin_vhit]

Dear all,
I want to monitor Use% of mount disk (Linux) on Zabbix. What should I do it? HELP ME, PLEASE..

Ex:
Filesystem Size Used Avail Use% Mounted on devtmpfs 2.0G 60K 2.0G 1% /dev tmpfs

I want to alert WARNING when Use% >= 85%
And alert CRITICAL when Use% > 95%

Here is an expression you can use in the trigger for the host you are querying.

cpanel10 is a cpanel-whm server here and we are monitoring the disk space used within that folder (as well as all the websites on there). Note you will need to have the zabbix agent running on the environment you are querying and allow the devices to talk to each other.

Hi jacobc,
Thank for support !
I was fixed it with solution below:

1. Create an item to measure the free space in the partition.
---
• Name : Free disk space on /mounted_disk on (percentage)
• Type : Zabbix agent
• Key : vfs.fs.size[/mounted_disk,pfree]
• Type of information : Numberic (float)
• Unit: %
• Update interval: 1m
• Application: Filesystems
---

2. Create a trigger to make an alert.
---
• Name : {HOST.NAME} - Free disk space is less than 20% on volume Mounted on
• Severity: Warning, High
• Expression : {Template OS Linux:vfs.fs.size[/mounted_disk,pfree].last(0)}<20
---

3. Create an action (we use a single generic Action for all triggers here) if you wan't zabbix_server to act when trigger is ON: send notifications, run commands ...
