Zabbix ZFS discovery monitoring

[koochy]

Hi,

thx for the great template. I've some problems using it. The discovery key Zfs Dataset discovery does not work for me. I'll get a error saying:

Global regular expression "ZFS fileset" does not exist.

I'll guess I've to set a Global regular expressions, but I did not find it. Can you please post?

regards

Don't need gsed, and save on a few PIDs too

Can replace that triple (g)sed with some awk:

/sbin/zfs list -H -o name | awk 'BEGIN {print "{ \"data\":["} {print ((NR==1)?"":",") "{\"{#FILESETNAME}\":\""$1"\"}"} END {print "]}"}'

/sbin/zpool list -H -o name | awk 'BEGIN {print "{ \"data\":["} {print ((NR==1)?"":",") "{\"{#POOLNAME}\":\""$1"\"}"} END {print "]}"}'

Sorry, I did miss that comment, the ZFS fileset regex is simply "/" (without the double quotes) with "character string included". Added this on share.zabbix.com .

Hello All,

I have developped discovery rules for zfs storage monitoring, and I'd like to share this with you.
This has been validated on Centos but may be easily adapted for Oracle servers (where the zfs is native).

Below are the steps needed to install the zfs discovery rules:

1) add the userparameter_zfs.conf file into /usr/local/etc/zabbix_agentd.conf.d directory on the host you want to monitor zfs

2) allow the zabbix user to run "zpool" and "zfs" commands
this is done by copying the "zabbix_sudo" file under /etc/sudoers.d directory

3) import the zbx_export_template.xml into zabbix

4) in zabbix gui add the "Template App ZFS" to the host you want to monitor zfs
this will create a refer and used item for each zfs fileset
also a zpool healt item, zpool available item. Graph will be also created


Feel free to comment and improve.
Regards

On which host do you execute step 2?
The zabbix server or the ZFS box?

Value should be a JSON object.

I want to monitor sol11 zfs filesystems,copied the files to my sol boxes and applied the template to them and it says "Value should be a JSON object." my zabbix 3.0.3 and the clients run sol11. any ideas?

You need gsed for the LLD to work correctly on Unix.You may also test the solution from the first comment by Myke on share.zabbix.com by changing the "UserParameter=zfs.pool.discovery" and the "UserParameter=zfs.fileset.discovery" lines in the zfs.conf file:

Can replace that triple (g)sed with some awk:

/sbin/zfs list -H -o name | awk 'BEGIN {print "{ \"data\":["} {print ((NR==1)?"":",") "{\"{#FILESETNAME}\":\""$1"\"}"} END {print "]}"}'

/sbin/zpool list -H -o name | awk 'BEGIN {print "{ \"data\":["} {print ((NR==1)?"":",") "{\"{#POOLNAME}\":\""$1"\"}"} END {print "]}"}'

If it still doesn't work, just try manually the command from zfs.pool.discovery and zfs.fileset.discovery to see where is the issue.

Thanks, I'll try it and let you know about the results.

how to add missing regular expression?

Hello

per: https://share.zabbix.com/operating-s...x/zfs-on-linux

"There is a missing regular expression named "ZFS Fileset" that you must create, the name is "ZFS Fileset" and the rule is:

Expression : /

Expression type : character string included"


Question: where do I put the missing regular expression?

[robfantini]

I thought there was an edit needed to one of the files. instead in zabbix:

To create a global regular expression:

Go to: Administration → General
Select Regular expressions from the dropdown
Click on New regular expression

Sorry for the late reply, you were right, there was a problem with the packages. Updated to the latest gsed and it works fine.

Thanks for your help!

on the client , put the file to /etc/sudoers.d/
