check_snmp_storage doesn't check all FS
Hi
I'm using nagios core 4.2.1 and check_snmp_storage
Version : 1.3.3
# Date : Jun 1 2007
On the Linux machine I got this info
[root@sgsvrasjdcs51lx:/]# df -kh

I do this check

OK : (<95%) All selected storages
Why the check didn't show the CRITICAL for /var/backup and /home ?
Thanks for the help

Re: check_snmp_storage doesn't check all FS
The -m / tells the script to only check /.I do this check
check_snmp_storage -H X.x.x.x -S0,1 -C public -m / -q "FixedDisk|NetworkDisk/other" -w95 -c98 -o 20000 -t 60
OK : (<95%) All selected storages
Please try the folowiing:
Code: Select all
check_snmp_storage -H X.x.x.x -S0,1 -C public -m ^/ -q "FixedDisk|NetworkDisk/other" -w95 -c98 -o 20000 -t 60

So you can see that "df -k" comand show /var/backup 100% used
the check show /var/backup: 95%used(1848MB/1952MB)
seems that df -k usign a different way to calculate the used space from the check
Why this difference ?

Re: check_snmp_storage doesn't check all FS
Can you share the full output of this command executed from the CLI of your Nagios Core machine:
My guess is that net-snmp isn't correctly reporting disk sizes. There are a few Red Hat errata out there that describe similar such problems relating to block size, though I don't recall them off-hand.

Re: check_snmp_storage doesn't check all FS
Hmm, the snmpwalk output is missing some important fields. Most importantly, hrStorageUsed and hrStorageSize. What's the output of these:

Re: check_snmp_storage doesn't check all FS
Your command
Seems to be working, as the output,
is generating a critical state because the drives used space is over 8% which is correct.
Code: Select all
check_snmp_storage -H 10.211.30.89 -S0,1 -C SGS-MGMT-01 -m ^/ -q "FixedDisk|NetworkDisk" -w5 -c8 -o 20000 -t 60
Code: Select all
CRITICAL : (>8%) /var/backup: 95%used(1848MB/1952MB) /var: 11%used(557MB/5102MB) /boot: 14%used(67MB/476MB) /home: 92%used(901MB/976MB) /: 61%used(3060MB/5038MB)
Be sure to check out our Knowledgebase for helpful articles and solutions!
Re: check_snmp_storage doesn't check all FS
The problem is not the critical state in my example but the difference from df -k output e the check_snmp_storage
[nagios@sgsvrasjdcs51lx:~]$ df -k

/dev/mapper/vg00-lv_slash ext4 5158520 3133140 1756700 65% /

/dev/sda1 ext4 487652 68273 393779 15% /boot
/dev/mapper/vg00-lv_home ext4 999320 923108 23784 98% /home

/dev/mapper/vg00-lv_backup ext4 1998672 1892356 1472 100% /var/backup
So you can see that "df -k" comand show /var/backup 100% used
the check_snmp_storage shows
CRITICAL : (>8%) /var/backup: 95%used(1848MB/1952MB) /var: 11%used(557MB/5102MB) /boot: 14%used(67MB/476MB) /home: 92%used(901MB/976MB) /: 61%used(3060MB/5038MB)
seems that df -k uses a different way to calculate the used space then the check_snmp_storage
So the unix administrator asks me why the var/backup is full and the nagios check show me /var/backup is 95% used
I hope to explained better the question/problem
Thanks

Re: check_snmp_storage doesn't check all FS
I think it's a discrepancy in the block sizes. df -k seems to be using 1024 byte blocks where as net-snmp is reporting the block size for /var/backup as 4096 bytes. As shown here:
Code: Select all
HOST-RESOURCES-MIB::hrStorageDescr.40 = STRING: /var/backup
HOST-RESOURCES-MIB::hrStorageAllocationUnits.40 = INTEGER: 4096 Bytes
