Nagios Support Forum

Hi,
I'm trying to monitor greenplum dca .
Installed the plug-in check_snmp_dca but getting the below error.Please help
./check_snmp_dca.pl -H Hostname -o 'Battery' -n 'Master' -i 1
ERROR: No response from remote host 'Hostname '.

Can you run a snmpwalk against the machine, and post the full output?

I have not seen this plugin before, so it's hard to say what the problem is.

snmpwalk is not installed
-bash: snmpwalk: command not found

I guess you've got redhat or centos, right?
first, lookup what package provides it:
second, install the package:

Possibly not with Core. On Debian it's sudo apt install snmp or depending on what version sudo apt-get install snmp.

Since we're asking...what version of Core are you using? Was it compiled from source or installed from distro repos? On what OS/version is nagios running? cat /etc/*-release may be of use.

I'm not able to install snmp.Repo is not installed properly i guess.

Yes, at this point, this is a Red Hat issue.

Is this server offline? If so, you can set up a local repo.
