I set up Nagios on a machine at my office to monitor our five linux printservers, and our three Novell servers.
My problem is as follows:
When I look at the "host details" part in the html interface of Nagios, I read "check_ping: %s: Warning threshold must be integer or percentage".
But when I look at the service details, it says that the ping is ok, and the loss is 0% or something like this.
The "last check" entry is also very strange to me; first, it was somethin in march 06 (when I first experimented with Nagios), now it says something like "August 17th", although it is run almost daily.
I know that the fault is probably some setting I did wrong, since I am no Linux or networking expert; but I read the documentation a lot, and checked the cfg files all over - but still I do not know why Nagios reports what it reports.
Can anyone help me? I would really appreciate help =)
