I feel your pain, most of the large mounts I need to monitor are on Solaris.
I'm still working on this and think I'm close to getting things to work.
Heres what I have so far:
I put the following script in /etc/sma/snmp (/etc/snmp for linux boxen)
Code:
#!/usr/bin/perl
use strict;
my $option=$ARGV[0];
my $mount;
my $total;
my $units;
my $used;
my $free;
my $line;
my (@cmd)=`df -g`;
#/export (export ): 131072 block size 512
frag size
#72551485440 total blocks 72551485072 free blocks 72551485072 available
72551485077 total files
#72551485072 free files 47513602 filesys id
# zfs fstype 0x00000004 flag 255 filename length
my $n=0;
my @lines;
while($cmd[$n]){
#my $count;
$line= "$cmd[$n]"."$cmd[$n+1]"."$cmd[$n+2]"."$cmd[$n+3]";
#$line=~s/\n//g;
#$line=~s/\s+/ /g;
$line=~s/\n//g;
$line=~s/^\s+//g;
$n+=5;
push (@lines,"$line");
}
foreach $line(@lines){
# if ($line=~/\w+\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\%\s+(.*?$)/){
if ($line=~/^(.*?)\s+\(.*\):\s+.*?\s+(\d+).*?(\d+).*?(\d+).*$/){
$mount=$1;
$units=$2;
$total=$3;
$free=$4;
$used=$total-$free;
unless ($mount =~/fd/){
if($option eq 'mount'){
print "$mount\n";
}elsif($option eq 'units'){
print "$units\n";
}elsif($option eq 'used'){
print "$used\n";
}elsif($option eq 'free'){
print "$free\n";
}elsif($option eq 'total'){
print "$total\n";
}else{
print "$mount $units $total $used\n";
}
}
}
}
exit;
then I modify my snmpd.conf by adding the following lines:
Code:
exec .1.3.6.1.4.1.2021.82 zfs_stats.pl /etc/sma/snmp/zfs_stats.pl mount
exec .1.3.6.1.4.1.2021.83 zfs_stats.pl /etc/sma/snmp/zfs_stats.pl units
exec .1.3.6.1.4.1.2021.84 zfs_stats.pl /etc/sma/snmp/zfs_stats.pl total
exec .1.3.6.1.4.1.2021.85 zfs_stats.pl /etc/sma/snmp/zfs_stats.pl used
a snmpwalk now looks like this:

now I just need to rewrite the zenoss.snmp.HRStorage collector to use the new
MIB space and add that to its own class. I'm new to python so it may take some
time (procrastination [Rolling Eyes] )
