Nagios XI - SNMP walk wizard not using MIB's

[jacek]

Hello,

I've recently noticed, that the SNMP walk wizard does not use the OID's from MIB's I've added (it is even saying that it is using SNMPv2-SMI in the "MIB To Use" column).
I presume this is the same topic as here (https://support.nagios.com/forum/viewto ... 16&t=30838), but I have no access...
Here You have the screen of the 1st and 2nd wizard steps, so You see what I've set:

NagiosXI-snmpwalkwizard-1.PNG

NagiosXI-snmpwalkwizard-2.PNG

Now below You can find the result of the snmpwalk command, where I explicitly told to use the QNAP MIB file and this works perfectly as You can see.

Code: Select all

snmpwalk -m /usr/share/snmp/mibs/QNAP-TS-221.mib 172.16.11.85 -v 2c -c public .1.3.6.1.4.1.24681.1
QNAP-TS-221::SystemCPU-Usage.0 = STRING: "100.00 %"
QNAP-TS-221::IfIndexEX.1 = INTEGER: 1
QNAP-TS-221::IfDescrEX.1 = STRING: "eth0"
QNAP-TS-221::IfPacketsReceivedEX.1 = Counter32: 2147483647
QNAP-TS-221::IfPacketsSentEX.1 = Counter32: 2147483647
QNAP-TS-221::IfErrorPacketsEX.1 = Counter32: 2
QNAP-TS-221::HdIndexEX.1 = INTEGER: 1
QNAP-TS-221::HdIndexEX.2 = INTEGER: 2
QNAP-TS-221::HdDescrEX.1 = STRING: "HDD1"
QNAP-TS-221::HdDescrEX.2 = STRING: "HDD2"
QNAP-TS-221::HdTemperatureEX.1 = Wrong Type (should be INTEGER): STRING: "34 C/93 F"
QNAP-TS-221::HdTemperatureEX.2 = Wrong Type (should be INTEGER): STRING: "33 C/91 F"

I presume I should somehow change the MIB to use? I tried to change the name to QNAP-TS-221 and go forward and back in the wizard, but this didn't help (didn't really expect it would, but hey, why not test?).
Maybe someone has access to the thread linked on the beginning of my post...?

What are the permissions on your MIB?

Code: Select all

ls -l /usr/share/snmp/mibs/QNAP-TS-221.mib

[tgriep]

When you run the wizard, try increasing the timeout to 180, the Max Results to 2000 and change the force scan to yes.
It might take a while to run this and that should help.
Can you run the following and post the output?

Code: Select all

 ls -l/usr/share/snmp/mibs

[jacek]

I've already thought about the same, as on the Nagios XI "Manage MIB's" You can see the permissions, and I noticed, that newly added had apache/apache.
So I deleted the MIB, re-downloaded the file keeping it's original name (file and OID inside the file): NAS-MIB.mib.
I corrected the permissions by copying them from other file, here is the result:

Code: Select all

ls -l /usr/share/snmp/mibs/
total 1820

I re-run the test, setting 180 timeout and 1000 results.
I've got exactly 26 OID's (exactly as before - I didn't fit them all into the previous screenshot, but they are exactly the same as the result from the cmd in my last post where I set which MIB to use).

I've also tested the wizard with blanking out the OID field, set 180 timeout and 5000 results limit which gave me 1417 results (hanging the web browser).
The MIB To Use column showed: SNMPv2-MIB, IF-MIB, RFC1213-MIB, IP-MIB, IP-FORWARD-MIB, TCP-MIB.

[gormank]

It may not matter, but you might run file on the files in the mib dir to see if they have DOS crlf and use dos2unix to fix any you find.

[tgriep]

Thanks gormank for the tip.

Can you post the MIB file so we can review it?

[jacek]

Thanks for the reply,
looks fine to me (look below), only the NAGIOS-NOTIFY-MIB.txt and NAGIOS-ROOT-MIB.txt have the CRLF terminators.
The only difference I see is the extension (*.mib instead of *.txt, but I can't imagine that this would be a problem on Linux).

I've also attached the file:

NAS-MIB.zip

[tgriep]

The MiB file looks good. I translated it and the OID's look correct.

Try running the wizard again but don't fill in the OID field. Does it find the OID's that you are looking for?

[jdalrymple]

A stab in the dark of my own - can you try importing this MIB also?

Nope, sadly not, its puking a lot of IP OID's etc.

Hmm, did it, but what You want me to do with it?
