Memory usage status

[Peter Pichler]

Hi,

I am trying to observe the memory usage of my virtual machine webserver (debian 6.0.7).
So I installed monit (apt-get install monit), set up the monit webserver + tried to observer the general usage of system ressources + apache2 + mysql

I added this to my configuration:

check system localhost
 if loadavg (1min) > 4 then alert
 if loadavg (5min) > 2 then alert
 if memory usage > 75% then alert
 if cpu usage (user) > 70% then alert
 if cpu usage (system) > 30% then alert
 if cpu usage (wait) > 20% then alert

On the website it says for all the things always 0%:

System	Status	Load	CPU	Memory
localhost	running	[0.02] [0.01] [0.00]	0.0%us, 0.0%sy, 0.0%wa	0.0% [0 kB]

I would appreciate help what I am doing wrong.

Thanks for your efforts,
Peter
