Hello All,
Nagios seems to be sending false alerts about few hosts, (ex: There were no
users on one host and still Nagios was reporting a critical alert and says
6 users are logged in. How do I fix this one?
Also, I have installed nagios and added 12 hosts as a start and monitoring
few details on them, how do I send false alerts and check if they are being
reported through nagios server?
