Nagios Support Forum

Hello,
i have installed Nagios Core along with its plugins. I have also installed snmp utils. The problem is that the check_snmp plugin does not appear anywhere. When i also run snmpwalk command, i get the error -bash: ./check_snmp: No such file or directory. Any idea?? What else should i install?

check_snmp is included as part of the nagios-plugins package. It's a totally separate thing from Nagios Core.

If you're following the official documentation for installing Nagios Core, there should be a "Installing The Nagios Plugins" step which should include the check_snmp plugin.

check_snmp: Requires the NET-SNMP package.
What OS and release are you trying to install the plugins on?

Hi,
the OS is Centos 6.7. I have followed the steps for installing net-snmp lib. I have also attached the following file. Any other idea?

Make sure the following packages net-snmp packages are installed on the server. If they are not, run the following to install them. Then recompile the plugins to see if the check_snmp plugin is built.
Make sure you run a first then re-run the configure script before recompiling.

If it still doesn't compile, in the folder where you compiled the plugins, there should be a config.log file.
Can you post it here?

Hi,
I finally installed it. I want to ask about mrtg, though. I have installed mrtg, but i get the error:
check_mrtgtraf: Unable to open MRTG log file
Which and where is this log file?

Moreover, which is the process for configuring mrtg to monitor a device?

Take a look at the MRTG installation guide for the information you are looking for at the link below.
