Hi Ahmed
Thanks for your question! Starting with the the January, 2010 release and updated in the May, 2012 release for SAS 9.2, the ARM Package includes the ability to analyze data from multiple servers and more specifically, multiple host environments. At a high level, you will need to update the setEnvLogs_*.sas programs as outlined in the installation and configuration instructions.

As you know with multiple servers, you have the added complexity of keeping track of not only which SAS service is represented by the log, but also which physical server. In the case of most grid implementations, this is usually accomplished with a shared file system which allows you to collect and analyze without first having to move the log files to a centralized location. When you have multiple SAS servers without a shared file system, you can either pre-process the SAS logs and move the SAS data or better yet, just collect the raw logs into a central location. In this latter scenario you will want to make sure that your naming conventions lend predictability to the log location.

Hope this helps!
