1. Must I be the root user in order to install and use the Linux® module component?
Yes. You must have privileges to install and uninstall loadable kernel modules on a Linux system.
2. How do I customize the events to be collected?
You can use the THOR.config file under the bin sub-directory on your Linux machine.
3. How many cores are supported? How many threads are supported?
The capability of the preview version is limited to 32 cores and 1000 threads. This restriction can be removed upon request.
4. Are there any differences between the support for IBM® JREs (Java™ Run-time Environments) and SUN JREs?
Most of the features are supported on IBM JREs and SUN JREs. The only difference is that we cannot determine the exact mapping relationship between a Java thread and a native thread using a SUN JRE. The mapping provided in the toolkit is based on guesses.
5. Are there any sample trace files to help me get familiarized with the tools?
There are two sample trace files included in the Visual Analyzer package.
