i'm trying to monitor a switch with nagios

i am using the default configuration as mentioned in the nagios monitoring document

snmp community string is not public

when i give the
#/usr/local/nagios/libexec/check_snmp -H XX.XX.XX.XX -C 'xxxxx' -o 'sysUpTime.0'

I get the output
SNMP OK - Timeticks: (297945372) 34 days, 11:37:33.72 | SNMPv2-MIB::sysUpTime.0=Timeticks: (297945372) 34 days, 11:37:33.72

But in nagios web interface i get the error
========
Current Status: UNKNOWN
Status Information: SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 1 [authpriv] XX.XX.XX.XX:161 sysUpTime.0

========

Can anyone help me..i am using all default configuration files
that comes along with nagios installation.


========
define service{
use generic-service ; Inherit values from a template
host_name linksys-srw224p
service_description Uptime
check_command check_snmp!-C public -o sysUpTime.0
}
=============
define host{
use generic-switch
host_name linksys-srw224p
alias Linksys SRW224P Switch
address XX.XX.XX.XX
hostgroups switches
}
===========
# Monitor uptime via SNMP

define service{
use generic-service
host_name linksys-srw224p
service_description Uptime
check_command check_snmp!-C public -o sysUpTime.0
}
==========
command.cfg configuration

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

Has this got to do anything with /etc/snmp/snmd.conf ?

Please guide

Hi there - were you able to resolve this issue?
I am too having problem but not too sure if yours is the same as I have.

Here's the error I'm getting when launching the command manually via terminal:
root@sybasedba2034:/usr/local/nagios# /usr/local/nagios/libexec/check_snmp -H 172.168.1.244 -C 'dbscomm' -o 'sysUpTime.0'
SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 1 [authpriv] 172.168.1.244:161 sysUpTime.0

In Nagios admin page I get this error:
"SNMP problem - No data received from host"

Email notification I get this:
***** NAGIOS *****
Notification Type: PROBLEM
Host: ciscoasa-firewall
State: DOWN
Address: 172.168.1.244
Info: PING CRITICAL - Packet loss = 100%
Date/Time: Fri Apr 24 15:49:50 EDT 2009

Please advise.
Thank you!

deibertine,

In my case it was an ip problem, the host configuration was reflecting a certain ip and in the dns the ip was pointing to another machine.

Not sure if this would be of any help to you.

Sorry but Im sort of confused on what you said...
Can you please briefly elaborate on the IPs you missed and which equipment were/had the issue?

Trying to get my snmp up and running but kept getting:
SNMP problem - No data received from host.
I've made sure that my cisco's snmp community is enabled et al - even configured my own community - running the command manually gave me the same error.
$ ./check_snmp -H 172.168.1.2 -P 1
SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m '' -v 1 [authpriv] 172.168.1.2

Any ideas?
I'd appreciate it.
Thanks!

I have same problem, snmpd is defenitly running as its supplying my cacti graphs nicely, in addition it responds to snmpwalk.

conclusion? either the nagios script has issues or we need to add something to the syntax that isn't documented.

ok guys the solution is to add -o .1.3.6.1.2.1.1.3.0 to end of command.

check_snmp arguments should assign as follows
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -o $ARG2$ -p $ARG3$



Here check_snmp parameters should assign as follows
check_snmp!xx.xx.xx.xx!communityname!mibs!snmp port

if snmp listen in default 161 port then no need to assgin that argument on command.cfg

instead of mibsname(like sysUpTime.0) you can use mib values as "Chrysalis" said but this snmp translation problem cause due to net-Snmp-perl rpm missing, By installing the net-SNMP-perl we can solve this problem.
