[Nagiosplug-help] check_snmp hangs

[Broughton, Brian]

You are correct the -c is a another type o.

Version of check_snmp I am running
check_snmp v1.4.16 (nagios-plugins 1.4.16)

I downloaded and compiled the latest version Friday, 1.4.16, I was using 1.4.11.

Copy and pasted the entire output from ps -aux | grep snmp
root      1961  0.0  0.0   9448   652 tty1     S+   06:42   0:00 ./check_snmp -H 192.168.98.1 -C PPGI -o iso.3.6.1.2.1.1.3.0 -P2c
root      1962  0.0  0.0  15356  2096 tty1     S+   06:42   0:00 /usr/bin/snmpget -t 1 -r 5 -m ALL -v 2c -c      192.168.98.1:161 iso.3.6.1.2.1.1.3.0

How does check_snmp pass this parameter?

Hello Brian,

I guess the '-c' instead of '-C' to specify the community string is also a typo. If I specify this incorrectly I get an error message:
./check_snmp -H testserver -o iso.3.6.1.2.1.1.3.0 -c public -P2c
check_snmp: Invalid critical threshold: %s
- public
Usage:check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range]
[-C community] [-s string] [-r regex] [-R regexi] [-t timeout] [-e retries]
[-l label] [-u units] [-p port-number] [-d delimiter] [-D output-delimiter]
[-m miblist] [-P snmp version] [-L seclevel] [-U secname] [-a authproto]
[-A authpasswd] [-X privpasswd]

Which version of check_snmp are you using? I have 1.72 on RHEL6 and RHEL5.

./check_snmp -V
check_snmp (nagios-plugins 1.4.9) 1.72

Maybe download and compile check_snmp?

Kind regards,

Gerrit van Ham

The -p2c is a typo on my part I am using -P2c.

Hello Brian,

I think you have to replace '-p2c' by '-P2c'.
The -p option is used to specify a port,
-P is used to specify the SNMP protocol.
Run check_snmp --help for more information.

Kind regards,

I originally posted this issue to Nagios forums but was directed to present this issue to developers of the plugin, see below.

Issue
Under Host Groups I have the following problem, the uptime on the router is listed as critical, (Service Check Timed Out)

Log file has the following entry Warning:
Attempting to execute the command "/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: Uptime\nHost: RD Cisco 8818\nAddress: 192.168.xxx.xxx\nState: CRITICAL\n\nDate/Time: Wed Nov 28 12:49:00 CST 2012\n\nAdditional Info:\n\n(Service Check Timed Out)\n"

When I manually run check_snmp it hangs.
/usr/local/nagios/libexec# ./check_snmp -H 192.168.xxx.xxx -o iso.3.6.1.2.1.1.3.0 -c comname -p2c
While check_snmp is running I ran:
ps -aux | grep snmp
I get the following output;
/usr/bin/snmpget -t 1 -r 5 -m ALL -v 2c -c   192.168.xxx.xxx:161 iso.3.6.1.2.1.1.3.0

When I manually run snmpget it will return;
snmpget -t 1 -r 5 -m ALL -v 2c -c comname 192.168.xxx.xxx:161 iso.3.6.1.2.1.1.3.0
iso.3.6.1.2.1.1.3.0 = Timeticks: (406909583) 47 days, 2:18:15.83

The community name is not being passed, is this normal?
I have the proper community name listed in switch.cfg, not sure what else I can do.
This is my first pass at setting up and using nagios.
Using Ubuntu 12.10 fresh install.
