THE VIRTUAL SERVER HANDBOOK

Managing the Virtual Server

Load

The Virtual Server has limits on the amount of resources it can use at any

one time. This makes it very important to manage the load you put on it.

The term "load" refers to the usage of the following:

Memory

CPU

Files open

Processes

The following table shows Virtual Server limits.

Server A

Server B

12 MEGS

Each Virtual Server needs limits to keep one Virtual Server from abusing

the performance of the physical host server.

To check the Virtual Server load

From the command prompt type:

% top

The Top command displays both cumulative totals of the host server and

totals of your Virtual Server:

load average

number of processes

CPU use

Memory use

Sample top command

The following is a sample of the output from running

 top:

load averages: 0.06, 0.02, 0.00      14:34:21

263 processes: 8 running, 249 sleeping, 6 zombie

CPU states: 44.0% user, 0.0% nice, 32.3% system,

0.0% interrupt, 23.7% idle
