I'm trying to moitoring switch with nagios. I had made everithing like in this tutorial: http://nagios.sourceforge.net/docs/3_0/quickstart-fedora.html, but i'm getting Status Information in nagios browser window like this:
(Return code of 127 is out of bounds - plugin may be missing)
So I had checked the google and found that i need to install check_snmp plugin. So how can I do it?
