Hello,
I am trying to monitor my switches with SNMP and when I run this command from the shell check_snmp!-C Public -o sysUpTime.0 -H 172.x.x.x I get the following error "-bash: !-C: event not found" ... any suggestions on how to fix this?
Thanks
Gavin

If you are running this from a bash type shell, you would want to be sure you are in /usr/local/nagios/libexec.(or wherever your libexec directory is if not standard) Then also remove the ! and replace with a [space]. The space\! issue is specifically what you are seeing with your error message.

You cannot run check_snmp!-C Public -o sysUpTime.0 -H 172.x.x.x directly from the shell. to test this from the shell run
Code: Select all
cd /usr/local/nagios/libexec
./check_snmp -C Public -o sysUpTime.0 -H 172.x.x.x
note the ./

when I run this command nothing happens, just get a blank line? however if I run this command I do get a response ./check_snmp-C Public -o ifOperStatus.1 -r 1 -m RFC1213-MIB -H 172.x.x.x ... just curious why one would work and the other one would not? I do get a SNMP ok when I monitor port 1 but get a (Service Check Timed Out) when monitoring the Uptime? any ideas?

It is possible that this device either doesn't know or isn't set to respond to sysUpTime.0 in it's snmp configuration

I used the OID .1.3.6.1.2.1.1.3.0 to query the service and it worked, not sure why sysUpTime.0 does not work but got it working this way.

You have to implement or download (what ever
) MIBs files. I have the same problem with my cisco router so i download the mibs files from the cisco site and now its work ok ...
for example i have Ubuntu server and this is what i did ...
cd /usr/share/mibs/netsnmp
wget ftp.cisco.com/pub/mibs/v2/SNMPv2-MIB.my
wget ftp.cisco.com/pub/mibs/v1/RFC1213-MIB.my
wget ftp.cisco.com/pub/mibs/v2/IANAifType-MIB.my
wget ftp.cisco.com/pub/mibs/v2/SNMPv2-TC.my
wget ftp.cisco.com/pub/mibs/v2/SNMPv2-SMI.my
echo "mibs +sysUpTime" >> /etc/snmp/snmp.conf
no sysUpTime is working great ... but you have to leave the .0 at the end ... for example if you monitor status of the interface ifOperStat.1 ..the number 1 indicate port 1 for sysUpTime.0 i dont know what is the 0 at the end but it do something
