Tom,
There could be several issues at work here.
If the time is not synchronized on the machine hosting your agent and
the HQ server, you may see false alerts on availability.
For instance, if the agent is reporting 5 minutes in the past, then
the server will believe that it has been down for 5 minutes, thus
filling in the availability as 0 (and thus generating alerts).
Since you are monitoring platform availability here, the agent only
needs to be able to contact the server to report that the platform
was available.
Verify your times and let us know. We typically recommend our users
run NTP.
