reply. I have checked the conn, it only stopped
10m(13:45~13:55). I want to know if the hobbit can check the
server's CPU and Memory when they Zero. If I can recevie some email from
hobbit. So I first know it. Can you give me some advice for hobbit setting?

graph, there is always some memory utilization and some CPU utilization
(seen via load average). I think the real problem is that something
went wrong with the agent on this machine, or it could no longer communicate
with the Hobbit server during this time period. You should review the alert
history for this node and then make sure that you configure alerts
appropriately. I suspect that you will find that all of the
agent-based tests went "purple" at about 1:30. The other thing to
check is the "conn" column -- if the system was not reachable, then the
purple alarms for the agent-based tests would have been suppressed in favor
of the reachability alarm.</SPAN></FONT><FONT size=3><SPAN lang=EN-US

<DIV><BR></DIV><SPAN class=Apple-style-span
style="BORDER-COLLAPSE: collapse">I think the answer to your question is: not
without some programming. I.e. you are looking for a parameter in
hobbit-client.cfg similar to the PROCS config with which you can specify both
a minimum and a maximum allowable number of processes, but in the memory case
you want to be able to specify a minimum as well as a maximum on memory usage
(ditto for cpu).
<DIV><BR></DIV>
<DIV>To do this you would have to write your own script. Note, this says
nothing about whether the usage *really* is dropping to zero or not. I think
Greg is probably right about the agent. </DIV>
