More than two years ago, I was demonstrating Chime on my laptop running Nevada. Chime is a visual interface to Dtrace that allows you scrutinize your applications.

Chime is available as a plugin for Netbeans. You can download the plugin from here.

I try it on my OpenSolaris laptop.

First, start your Netbeans IDE, and go to Chime tab :


As an example, I chime a process, top, running on my laptop. You can get the following information,

Time spent in functions:

Number of System calls your application is performing. In the screen shot below, you see that top is performaing 66 System Calls Per Second:

You can also see the impact on the system up to the System Probes:

Of course, you have many more probes available, and you can create your own probe, with Dtrace.

Do you know Jumpbox?

Jumpbox provides appliances that can be run on the Amazon Cloud. I just tested one appliance, the OTRS one. This appliance is provided to you for one hour (gratis) of test on Amazon.

Once you run in the trial, you are then able to administrate your appliance:

You can then play with OTRS (running in the cloud):

It's cool, because the setup took me less than 3 minutes. The tested configuration was:

Application Version: OTRS 2.3.4
JumpBox Version: 1.1.7 (Release Notes)
OS Version: Ubuntu 8.04 LTS
Download Size: 191 MB

You can also download the appliance and run it in VirtualBox 2.2.
