SNMPv3 and API for Netapp

Arethusa · November 7, 2022, 3:45pm

Hello,

I’m on Check_mk Raw edition 2.1.0
OS : Debian 10

I try to add a NAS Netapp on check_mk with SNMPv3

I think my basic configuration is ok because the snpwalk works (from check_mk server to the Netapp).

root@CMK01:~# snmpwalk -v 3 -u snmpv3user -a SHA -A Password! -x DES -X Password! -l authPriv 172.20.1.7 .1
iso.3.6.1.2.1.1.1.0 = STRING: "NetApp Release 9.10.1P4: Mon May 09 22:11:44 UTC 2022"
iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.789.2.5
iso.3.6.1.2.1.1.3.0 = Timeticks: (1173384307) 135 days, 19:24:03.07
iso.3.6.1.2.1.1.4.0 = STRING: "*********"
iso.3.6.1.2.1.1.5.0 = STRING: "AFFA200"
iso.3.6.1.2.1.1.6.0 = STRING: "*******"
iso.3.6.1.2.1.1.7.0 = INTEGER: 72
iso.3.6.1.4.1.789.1.1.1.0 = INTEGER: 2
iso.3.6.1.4.1.789.1.1.2.0 = STRING: "NetApp Release 9.10.1P4: Mon May 09 22:11:44 UTC 2022"
......

I have 144 lines.

On check_mk, I try 2 things:

And… That works good, but I have only 17 Services:

I remember on other Netapp where I have near 70 or 80 services.

So why only this service ? I have lot of more result with SNMWALK.

I Try API with user monitoring:

So with that I Try to had API User option:

checkmk_bug_08

But I have this error:

Any ideas ?

Regards.

This is normally the only way to monitor a Netapp.
After you configured the special agent you can view the created command on the shell with “cmk -D hostname”. If you execute the special agent command manually it is possible that you get more output than the “exit code 1”

Hello,
Thank you for answer.

With SNMPv3, when I do the cmk -D nas, I see that:

If I try with only API :

Check_mk see 0 service.

Thank you.

What happens if you execute the command shown at → Type of agent: → Program: ?
The SNMP output is fine but not relevant for the real monitoring of the Netapp.

Hello,
Thank you for you availability,
I don’t understand “if you execute the command shown at → Type of agent: → Program: ?”
However, I try this check to exclude a mistake :

root@CMK01:~# curl -skL -w "%{http_code}" "https://@ip/sysmgr/v4/" -o /dev/null
200

So we are sure check_mk can go on API.

Regards.

That look like this problem (2.1.0b5):

Is it a bug from my RAW 2.1.0 ?

Regards.

Hello again,

To follow up on the previous message, I try on older Check_mk server : 2.0.0p16 (CRE)
And it works good. I have 150 metrics.

So we can deduce my manipulations on RAW 2.1.0 are good. So maybe we have a bug on 2.1.0 or my version is corrupted.

Any ideas to fix it ?

Thank you.
