Umm, are those parameters valid in nagios1.x??
alhmngsrv2:/etc/nagios# grep service_interleave_factor nagios.cfg
alhmngsrv2:/etc/nagios# grep inter_check_delay_method nagios.cfg
I don't have such parameters....

Hello Hendrik,
The machine is a DL380, 2xCPU 2.8Ghz, 2Gb RAM. I think it has enough hw resources..... Technically:
alhmngsrv2:/etc/nagios# vmstat 5

It's very strange, because, when I start nagios, everything goes nicely, plugins execution times and latencies are ok, but two or three minutes later, nagios starts getting strange time values, for example:
1120644060 FIREWALL PING OK 1 HARD 9 157 FPING OK - 192.168.0.1 (loss=0%, rta=72.400000 ms) loss=0%;10;30;0;100 rta=0.072400s;2.000000;5.000000;0.000000
Executiontime=9 and Latency=157 ¿?¿? Why? This test have had no packet loss, the machine is working nicely....but...
Another strange thing I noticed: if have "max_concurrent_checks=120", why are so many times that nagios is running only 1,2,3,4 plugins at the same time?
It's true, I'm very confused....
Thx in advance,
Javier.

Hello Javier,
try to figure out where your Service Latencies comes from.
Hints are:
in nagios.cfg
process_performance_data=0
http://nagios.sourceforge.net/docs/1_0/perfdata.html
Out of the performance data you can perhaps see where your latencies comes from.
Other ways were to view a 'top' and have a look to the swap memory, the load and perhaps the 'wa' CPU count
Its not quiet good to have a server swapping, to have a high load and very ugly if your server is waiting for I/O...
