Solaris ZFS

[mixmegapol]

Hi all

I have some Solaris [10/11] Servers which I need to monitor.
Does anybody has experience with monitoring ZFS ?
I get different dataset but there aren't any zfs commands used (v 2.4.7).

Can someone help?
Kind regards
Daniel

Yes I have experience with monitoring ZFS

Can someone help?

Control question: on what exactly?

Hi kloczek

Thank you for your reply!

I supposed zfs would be better supported as there are zabbix-agents already compiled. It isn't useful to use df's with ZFS.

Now, I have two files:
- solaris_get_zfs_fileset.perl:
#!/usr/bin/perl

use strict;
use warnings;

print "{\n";
print "\t\"data\":[\n\n";

my @array = `zfs get -Hp name`;
my $n;
$n = @array;
my $linenumber;
$linenumber = 0;
foreach my $line (@array)
{
$linenumber++;
my @cols = split(/\t/, $line);
# print "$cols[0]\n";
print "{\t\t\"{#FILESETNAME}\":\"$cols[0]\"\n";
print "\t}\n";
if ($linenumber == $n) { } else { print ","; }
}
print "\n\t]\n";
print "}\n";

- solaris_get_zfs_pool.perl
#!/usr/bin/perl

use strict;
use warnings;

print "{\n";
print "\t\"data\":[\n\n";

my @array = `zpool list -Ho name`;
my $n;
$n = @array;
my $linenumber;
$linenumber = 0;
foreach my $line (@array)
{
$linenumber++;
my @cols = split(/\t/, $line);
# print "$cols[0]\n";
chomp($cols[0]);
print "{\t\t\"{#ZPOOLNAME}\":\"$cols[0]\"\n";
print "\t}\n";
if ($linenumber == $n) { } else { print ","; }
}
print "\n\t]\n";
print "}\n";

- userparameter_zfs.conf:
UserParameter=zfs.pool.discovery,perl /opt/zabbix_scripts/solaris_get_zfs_pool.perl
UserParameter=zfs.fileset.discovery,perl /opt/zabbix_scripts/solaris_get_zfs_fileset.perl

UserParameter=zfs.zpool.health[*],/usr/sbin/zpool list -H -o health $1
UserParameter=zfs.get.fsinfo[*],/usr/sbin/zfs get -o value -Hp $2 $1

Do I go into correct direction?
Either I can do a file with this perl-scripts or I can find somewhere an already working ZFS-Template.

I found a template, but the sed-commands aren't solaris-compatible (I would have to use the gnu sed version, but I rather won't do that).

And as the '|' isn't working in the conf-file (e.g. zpool list | awk '{print $3}' ; I had to use a script..

How did you solve that? I'm very new to scripting.

The next problem is the output of 'zpool list':
I get percentages :

boarder05 ~ $ zpool list
NAME SIZE ALLOC FREE CAP HEALTH ALTROOT
datapool 39.8G 26.1G 13.6G 65% ONLINE -
ftppool 199G 36.4G 163G 18% ONLINE -
rpoolp 59.5G 16.0G 43.5G 26% ONLINE -

Is there a way to get the output of capacity and size in bytes/numbers instead of human-readable format and '%' ?

I don't know how to do.

It would be great if you could help me!

Kind regards
Daniel

The answer is "use data from zfs, not zpool".
