Host check timed out check_snmp_synology

[scottwilkerson]

Is this what you're asking for?

Code: Select all

define command{
       command_name    check_snmp_synology
       command_line    $USER1$/check_snmp_synology -h $HOSTADDRESS$ -u $USER3$ -p $USER4$ $ARG1$
}

yes. Does NAS02 use the same username/password set in $USER3$ & $USER4$ that NAS01 does?

Yes it does.

So if you run this command from the CLI for both NAS01 and NAS02 do you get valid results for both

Code: Select all

/usr/local/nagios/libexec/check_snmp_synology -u USERNAME -p PASSWORD -h HOSTIP

I can only get a valid response from NAS01.
With NAS02 i get the request timed out response.

Ok, are you sure NAS02 has SNMP v3 enabled with the same username and password, because it appears that it isn't able to connect

Hi Scott,

Yes im certain that username and password are the same on both NAS boxes.

NAS02 is located in another office, and im wondering if the ISP could be blocking the requests?
I have of course access to the core router, and both are configured in a similar way.

Bg.

That is a very real possibility as these are UDP packets it becomes difficult to see where they are falling off.

[lroslundh]

Do you know which port i need to enable on the core router in order to allow incoming UDP traffic with this plugin?

UDP port 161?

[scottwilkerson]

Yes, these go outbound from the Nagios server to UDP port 161
