Thanks guys for the thoughts. The server does Nagios for us. The system does log everything, but the iowait time is very low and hte number of iops is low. It's monitoring >450 services, and can sometimes be pretty busy with little tiny jobs like pinging a host 10 times, and such. Sometimes this makes the load average high for a very short time. The CPU is not at 100% at these times and the server is not feeling sluggish. It just has a lot of things running. There is no reason for it to delay incoming connections.
As we have grown we have split apps up that were once together on the same server. This box was once Cacti, Nagios and ticketing. Now it's just Nagios and ticketing. We did not want any email to be delayed, period. I just want to figure out how to adjust that load average that kicks off those rejection of connections.... until the new servers are ready for Nagios and the ticketing system to each have their own. So, how do I adjust the number ? Thanks, Mike On Mon, 2008-02-04 at 15:02 -0800, James G. Sack (jim) wrote: > Neil Schneider wrote: > > If it's only momentary and seldom, it shouldn't matter much.
