snmpwalk works on EdgeSwitch 16 XG but check_snmp fails

[scottwilkerson]

Can you show the definition for your check_snmp command?

[Ulfandu]

Here it is. I believe I haven't touched it at all.

Code: Select all

define command {
    command_name    check_snmp
    command_line    $USER1$/check_snmp -H $HOSTADDRESS$ $ARG1$
}

Looking back, you ran it from the CLI with -C firmasnmp but in your command you have -C testsnmp

[Ulfandu]

Yeah, I did because I have no such SNMP community called "testsnmp" - that's just a placeholder to not reveal my company's name. So I forgot to edit that line because I didn't want to reveal the company's name where I work - oh well.

EDIT: replaced that to "testsnmp" in the previous post.

The only other thing I can think that could be the problem is if 10.2.1.35 isn't really the address specified for the host net-sw-6

[Ulfandu]

That's what I thought at first. Here's some images to assure you that the address is in fact correct.

And here's the SNMP community settings for the switch:

But what is set in the address field in the Nagios configuration file for the host net-sw-6?

[Ulfandu]

Now I feel like an idiot... The IP address was incorrect all along. I thought I had already checked it, and I most likely had, but for some reason I didn't notice the typo:

Code: Select all

define host {
    use                     generic-switch
    host_name               net-sw-6
    alias                   Ubiquiti EdgeSwitch ES-16-XG - Upstairs
    address                 10.2.1.25
    hostgroups              switches
    icon_image              ubiquiti.png
}

I've now corrected it to 10.2.1.35 and the checks are working:

glad to hear it is resolved!!!
