How Do I install the Nagios check_snmp Plugin?

  • 772

I have installed Nagios in my ec2 server. Now I want to install check_snmp plugin. I found that this is not available in :

/usr/local/nagios/libexec

I tried : 

sudo apt-get install nagios-plugins-snmp

But I'm getting :

E: Unable to locate package nagios-plugins-snmp

How can I install the plugins?

Thanks in advance.

  1. This is in the nagios-plugins-standard package. I'd suggest installing the nagios-plugins package, as that will install it, as well as the nagios-plugins-basic package:

    sudo apt-get install nagios-plugins

    Then, your SNMP plugin will be available in:

    /usr/lib/nagios/plugins/check_snmp

  2. On your monitoring server:

    sudo apt-get install nagios-plugins

    All standarded plugins will be installed in

    /usr/lib/nagios/plugins/

    Not in 

    /usr/lib/nagios3/

    Please see Nagios - Official Ubuntu Documentation in the section of "Configuration Overview"

    Then in

    /etc/nagios-plugins/config/

    you will find snap.cfg, which assigns each command_line a correspondent command_name.

    For example

    define command{
    command_name    snmp_load
    command_line    /usr/lib/nagios/plugins/check_snmp -H '$HOSTADDRESS$' -C '$ARG1$' -o .$
    }

  3. I had this same issue and found the problem.

    The point is that when you have installed the nagios-plugins, you shouldn't had net-snmp and net-snmp-utils packages installed at all. And thats why check_snmp were not compiled.

    For fix this, you have to install net-snmp and net-snmp-utils and after that compile/install nagios-plugins again.

  4. If you install nagios 4 following this tutorial, then your installation directory is /usr/local/nagios.

    On starting nagios and browsing to nagios admin portal, you could see the following errors

     - (No output on stdout) stderr:
   execvp(/usr/local/nagios/libexec/check_ping
 - (No output on stdout) stderr:
   execvp(/usr/local/nagios/libexec/check_users
 - (No output on stdout) stderr:
   execvp(/usr/local/nagios/libexec/check_http

    This is how I fixed the above errors,
    Install plugins

    sudo apt-get install nagios-plugins

    This will install all plugins to /usr/lib/nagios/plugins directory.

    Just copy all files starting with check_* to /usr/local/nginx/libexec.

    cp /usr/lib/nagios/plugins/check_* /usr/local/nagios/libexec

    and wait for nagios to reload/refresh browser window
