Re: [Nagios-users] check_snmp_load and check_snmp_mem output (null) issue.
Looking at the config it seems that the community string reference in the
pasted command definition (-c $ARG3$) will refer to the parameter 90 from the
service definition, when the manual run shown implies 90 should be the
critical value, not the community string. A possible fix would be adding
!public! in the service definition and changing the community string call to
-c $ARG4$ in the command definition.

So I have an odd issue. Running check_snmp_mem.pl and check_snmp_load.pl
from Manbulon's check_snmp plugins is returning (null) and I can't figure out
why.
(The firewall is an Astaro/Sophos UTM 320)
I tried turning on debugging, this is the output:
[1360352407.069695] [016.1] [pid=23937] HOST: clk_astaro, SERVICE: Firewall
Load , CHECK TYPE: Active, OPTIONS: 0, SCHEDULED: Yes, RESCHEDULE: Yes,
EXITED OK: Yes, RETURN CODE: 2, OUTPUT: (null)
If I run the command by hand, it works fine, as the nagios user, I've also
verified the nagios user has write access to /tmp just in case:
nagios@monitor:/usr/local/nagios#
/usr/local/nagios/libexec/check_snmp_load.pl -H 192.168.0.2 -C public -T
stand -w 25 -c 90
2 CPU, average load 5.0% 25% : OK
Here's the command:
define command{
command_name check_snmp_load_v1
command_line $USER1$/check_snmp_load.pl -H $HOSTADDRESS$ $USER7$ -T $ARG1$
-w $ARG2$ -c $ARG3$ $ARG4$
}
And the service definition:
define service{
use generic-service ; Inherit values from a
template
host_name clk_astaro
service_description Firewall Load
check_command check_snmp_load_v1!stand!25!90
}
$USER1$ and $USER7$ are defined in resource.cfg:
$USER1$=/usr/local/nagios/libexec
$USER7$=-C public
The only changes to the plugin are for fixing the error for a version string,
from this page: https://wiki.icinga.org/display/howtos/check_snmp
Argument v6.0.1 isn't numeric in numeric lt ()
This sources from old plugins getting a changed version string in
libnet-snmp-perl. This can be fixed by replacing all occurences of the
integer less than equal by the string compare 'lt'.
# sed -i 's/Net::SNMP-VERSION 4/Net::SNMP-VERSION lt 4/g'
check_snmp_mem.pl
Any ideas? All of the other services/checks work fine.

Re: [Nagios-users] Monitoring a host behind VPN/Firewall
Gilberto, There is surely a more elegant way, but if you add an extra test in the client that returns OK plus the date and time, and call this test _Last likely update or something of that sort, you will at least know if the data is stale. It is a short batch file: ** @echo off echo OK: %DATE% %TIME% exit /B 0 ** Fernando ** On Oct 22, 2012, at 6:07 AM, Gilberto Ferreira gilberto.nu...@selbetti.com.br wrote: Nobody??

Re: [Nagios-users] Monitor Cisco Uptime
For uptime we use Perl to clean up the response and convert ticks to minutes, before sending to Nagios.
