Log CPU, mem and network utilization for uncovering client-side bottlenecks
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
I'd like to monitor the utilization of CPU, memory and network interface
(i.e. a percentage value for all three parameters) during a JMeter test
execution on the client node(s) in order to uncover and avoid possible
bottlenecks on client-side.
Does anyone have a nice script (for Linux systems) which might be
started in parallel to
JMeter, logging the data to a file in certain time intervals to enable
later analysis?
Best regards,
André

Thanks Justin,
sar seems to cover what I was looking for!

What you need is sar, it is included in most sysstat packages. It runs
from cron and logs everything you need to know to a file. You could use
something like kSar (http://ksar.atomique.net/) to have a nice graphed
view of the output.
