RE: very high cpu percentage

[Mike Robertson]

The web report for cpu appears to provide correct values for cpu utilization
and the mail alerts appear to have this value x 100

Hi,

1.) please try to run monit in foreground for few cycles and send us the 
output (stop monit daemon and run "monit -vI" for few cycles).

2.) please attach the output of:

   cat /proc/stat
   cat /proc/cpuinfo

Thanks,
Martin
