from time to time our webserver is not able to react on http, pop, smtp... because of too high cpu usage for some seconds.
The monitoring of those services shows me that they are off for some seconds.
Is there any script existing, that logs hte outpout of the command "top" or something else, if the cpu-usage gets higher than a given value ?
Or do you have any idea how get to know what is wrong in those seconds ?
It a suse 11 system with normally 1-2 % cpu usage...
