Agent & Solaris 10 with ZFS?

[jsosic]

Hi.

My Agents (1.8.1) can't read free space on ZFS partitions. Is there a way to fix this?

It looks like 1.8.2 is worse than 1.6.[56]:-(

In the earlier versions, I got somewhat reasonable results for FS size, free space. But now I see all numbers in the multiple TB range:-(

[mw46d]

Actually, it looks like the agent/agentd (1.8.2) report reasonable values:-(

[root@] # zabbix_agentd -t vfs.fs.size[/,free]
vfs.fs.size[/,free] [u|887984743424]
[root@] # zabbix_agentd -t vfs.fs.size[/,total]
vfs.fs.size[/,total] [u|891122455040]
[root@] # zabbix_agentd -t vfs.fs.size[/,pfree]
vfs.fs.size[/,pfree] [d|99.647892]
[root@] # zabbix_agentd -t vfs.fs.size[/,used]
vfs.fs.size[/,used] [u|3137711616]

But what the server has in it's `last 500 values' is completely different:-(
Some values from the DB for that host:

mysql> select itemid, type, hostid, key_, lastvalue, lastclock, prevvalue, value_type, units from items where hostid = '10111' and key_ regexp 'vfs.fs.size\\[/,';

and for a zone on that host, where the numbers are even more weired:-(

1.8.2 agent still not working.. at least for me

not working, at least for a respectable sized zfs pool (9.8T) on a x4500. is this because its big?

Odd, ZFS has *only* been around a good 5 years now and is widely used, i can't believe it's still not properly supported.

For me that means we can't use zabbix at all.
