performance problems

[Hendrik Baecker]

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...
