Re: [Nagios-users] status.cgi very high cpu usage = Problem gone away
Not slow because of many requests, slow because cpu execution time is like 30 times slower, effectively running like 100Mh i486 cpu (benchmark on the console only, disconnect all network NIC. So no ; not because of Google :-) Obviously vmware is doing something nasty. When the box is slow and high load, the host load is still rather low.

Re: [Nagios-users] status.cgi very high cpu usage = Problem gone away
Hi, The most scary thing is, as suddenly like when it came, it suddenly went away this morning. Not any changes to the nagios system or vmware guest and hosts. I have been doing the similar benchmark of status.cgi on the real host with the same status.dat file with the host having problem. It takes 0.1 sec to process, and in the vmware host it took 3.9 second. I have a quick look of how status.cgi parse the text file and see lots of memory cmp (strcmp call to libc) and move. So my wild guess is that memory operation on the vm is terribly slow for some reason. And suddenly as come from nowhere, it just become as fast as normal. Any one has a bright idea of what is going on ? Thanks -- Steve Kieu Mob: (+64) 021 250 6437 - This SF.net email is sponsored by: Microsoft Defy all challenges.
