Hi,
Anyone know of a good procedure or command that will significantly increase the load of my server without crashing it?
I want to run some threshold tests and monitor load, cpu and memory usage.
Thanks

Hi ALL,
I have to develop a script which checks for the load on CPU on regular intervals. I created a simple script which uses 'uptime' command to find out the avg load in the last 5 min. I then used grep and put the value of the avg load in a variable OUT.
It was working fine till... (5 Replies)
Friends
I have noticed that the Sun Fire v490 server with Solaris9 OS in my office, is showing a load of 12.50 during peak time and the CPU showing a max of 75% and an average of 60%.

Deal All,
I'm writing a simple awk to generate some sort of report. The awk will check 24 files (file generated each one hour in a wholoe day) and then it will print one field to another file for counting purposes.
The script is working fine but the problem is that the CPU load is very high... (10 Replies)
I had the query as to whether the load average in a multi CPU machine should be
(load average/no of CPUs)
We have 4 CPU on our VMware RHEL instance, so the load average should be
Load average/4.
I hope, my question is clear.
Please revert with the reply to my query.

Hello,
on my VPS load is above normal. It is around 2.00 all the time.
But VPS has assigned:
1000 CPU units, one core.
Does it mean VPS needs faster CPU, or can balance high load any other way?
The load is 70% used by process: bogofilter

ffcfstress(1) General Commands Manual ffcfstress(1)NAME
ffcfstress - constant force stress test for force-feedback devices
SYNOPSIS
ffcfstress [-d <device>] [-u <update rate>] [-f <frequency>] [-a <amplitude>] [-s <strength>] [-x <axis>] [-A] [-o]
DESCRIPTION
ffcfstress stress tests constant non-enveloped forces on a force feedback device. It simulates a moving spring force by applying a fre-
quently updated constant force effect.
Beware, the stress test may damage your device!
OPTIONS
At least one option is required.
-d <device>
The device to test (by default /dev/input/event0).
-u <update rate>
The update rate in Hz (25 by default).
-f <frequency>
The spring center motion frequency in Hz (0.1 by default).
-a <amplitude>
The spring center motion amplitude, between 0.0 and 1.0 (1.0 by default).
-s <strength>
The spring strength factor (1.0 by default).
-x <axis>
absolute axis to test (default: 0)
[0 = X, 1 = Y, 2 = Z, 3 = RX, 4 = RY, 5 = RZ, 6 = WHEEL]
-A switch off auto-centering
-o Dummy option, useful when all defaults should be used.
