After upgrading from zabbix 2.2 to 3.0.3 problem with vfs.fs.discovery

[zalex]

vfs.fs.discovery in zabbix version 3 now detects floppy, CD-ROM, USB mount point, e.g. /proc/bus/usb, the free space which is equal to 0. In the result of a lot of false triggers. Zabbix agent is used version 2.2. How can I fix it?

Resolved in manual

After DB upgrade zabbix to version 3, disappeared the filter rules in LLD templates, e.g., {#FSTYPE} = @File systems for discovery; {#IFNAME} = @Network interfaces for discovery; and so on. Had to add a filter rule LLD manually in all templates. It's not a small job. The triggers had to be removed manually. A screen shot is attached.

I think updating the database from version 2.2 to version 3 ill-prepared developers.

Hello zalex!

Are you using filters in discovery rule?

You can create regular expression in Administration -> General -> regular expression
with

expression type: Result is false

and

expression: ^(cdrom|usb|....)

Add this expression to discovery rule filter to exclude listed mounts from discovery.
Or you can create Regular expression with Result is true and list all mounts you whant to discover.

Hello Dmitryb

Regular expressions in Administration -> General -> regular, after the updates were in place. The problem was that the templates disappeared setting filters for LLD (low level discovery). See my post above.

Goodmorning!

There was same issues with Oracle DB in past. As i remember, problem was in Oracle, and it was not reproducible.

[zalex]

Good morning!

The Zabbix developers claim that Oracle's fully supported, but DB2 only in experimental mode.
