Nagios Monitoring for QNAP

[Brick]

I am writing a Nagios plugin to monitor our TS-809U

There are some existing ones out there but some do not work on this model and I am hoping to combine them all together into one plugin.

I am using SNMP to gather the information, memory, cpu, fans etc are all fairly streight forward but I'm having some issues with the Drive Space.

There are SNMP checks for-

Code: Select all

HOST-RESOURCES-MIB::hrDeviceDescr.1552 = STRING: SCSI disk (/dev/sda)
HOST-RESOURCES-MIB::hrDeviceDescr.1553 = STRING: SCSI disk (/dev/sdb)
HOST-RESOURCES-MIB::hrDeviceDescr.1554 = STRING: SCSI disk (/dev/sdc)
HOST-RESOURCES-MIB::hrDeviceDescr.1555 = STRING: SCSI disk (/dev/sdd)
HOST-RESOURCES-MIB::hrDeviceDescr.1568 = STRING: RAID disk (/dev/md0)

And their maximum capacities-

Code: Select all

HOST-RESOURCES-MIB::hrDiskStorageCapacity.1552 = INTEGER: 488386584 KBytes
HOST-RESOURCES-MIB::hrDiskStorageCapacity.1553 = INTEGER: 488386584 KBytes
HOST-RESOURCES-MIB::hrDiskStorageCapacity.1554 = INTEGER: 488386584 KBytes
HOST-RESOURCES-MIB::hrDiskStorageCapacity.1555 = INTEGER: 488386584 KBytes
HOST-RESOURCES-MIB::hrDiskStorageCapacity.1568 = INTEGER: 1460452800 KBytes

But there doesnt appear to be any checks to show how much of this is in use- despite the information being shown in the GUI... am I missing something?

The only usage level I can find is this-

Code: Select all

HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: /sys
HOST-RESOURCES-MIB::hrStorageDescr.2 = STRING: /tmp
HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: /proc/bus/usb
HOST-RESOURCES-MIB::hrStorageDescr.4 = STRING: /mnt/ext
HOST-RESOURCES-MIB::hrStorageDescr.5 = STRING: /mnt/HDA_ROOT
HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: /share/MD0_DATA
HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: /.eaccelerator.tmp

HOST-RESOURCES-MIB::hrStorageSize.1 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageSize.2 = INTEGER: 8192
HOST-RESOURCES-MIB::hrStorageSize.3 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageSize.4 = INTEGER: 79348
HOST-RESOURCES-MIB::hrStorageSize.5 = INTEGER: 130421
HOST-RESOURCES-MIB::hrStorageSize.6 = INTEGER: 359384007
HOST-RESOURCES-MIB::hrStorageSize.7 = INTEGER: 8192

HOST-RESOURCES-MIB::hrStorageUsed.1 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.2 = INTEGER: 23
HOST-RESOURCES-MIB::hrStorageUsed.3 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.4 = INTEGER: 11200
HOST-RESOURCES-MIB::hrStorageUsed.5 = INTEGER: 4388
HOST-RESOURCES-MIB::hrStorageUsed.6 = INTEGER: 225674788
HOST-RESOURCES-MIB::hrStorageUsed.7 = INTEGER: 0

This is showing the sizes of folders on the NAS with their max size and size in use... What I don't want to happen is for me to setup a script that checks the /share/ folder and then discover that its possible for data to grow outside of this folder and for my check to return a false result. Is all of the data stored on the device always put in this /share/ folder?

Any thoughts or ideas or other OID's I could use? Any idea what those other folders do?

[Brick]

Also- does anyone out there have a NAS that currently has a failed drive or other error?

I'd like to see what the snmp data looks like when its reporting drive failures...

If you want to give it a try:

http://www.charlieroot.de/downloads/check_snmp_qnap.pl

Should work with all models supporting SNMP.

Sample output:

[helmut@BSDHelmut ~]$ sudo /usr/local/libexec/nagios/custom/check_snmp_qnap.pl -H qnap569pro -a
OK - All monitored parameters within limits

Was a QPKG ever finished?

Hi HelmutR

The script is really good, although we had to modify it for it to sort the keys the right way.

We noticed that when we physical removed "Disk 3" from the Qnap enclosure (TS-1253BU-RP) Then the script output said "Disk 6 N/A"

We did modify the
foreach my $index (sort keys % lines to foreach my $index (sort { $a <=> $b } keys %

after that the script works with the sorting issue and the right Disk got the status N/A

Thanks alot again HelmutR

I ended up using NemsLinux since it is based on Nagios Core but has tons more options and features. Runs on Rasberry Pi, Pine64 or ODROID SBC's more info here: https://nemslinux.com/

[Toxic17]

NemsLinux has now been ported to a Virtual Appliance build in three formats.

OVA, VHD and QCOW2 builds.

More over here: https://nemslinux.com/download/nagios-v ... liance.php

I have not installed any of this on my NAS as yet but the OVA/vhd should work without any issues. the QCOW2 may work but the file extension needs to be renamed.

Hello all,

thanks for pointing out NEMSLinux even if the post was a few years ago....
I imported it and it runs fine on QNAP TS-453A with V5.xx
All ready put together and tops equipped. I've been doing Nagios for years, but this distro completely passed me by. Surely for the masses a very big help not to run everything themselves in a VM or as Docker on the QNAP.
For this NEMS gets a PUSH from me
Greetings
