I was bored recenlty and decided to create a tool which helps to analyze output files of the SAP NetWeaver Java application server. In this very first release you can open multiple std_server* output files from the application server’s work folder (usr\sap\<SID>\<instance name>\work) even for multiple server nodes in the same time. For example: std_server0.out, std_server0.ou0, std_server1.out, std_server1.ou0 files can be opened and then you can choose which server node data you want to display once all data is parsed. It’s also possible to zoom into the diagrams. Displayed values can be heap memory usage before and after GC, average memory and GC frequency. As the tool is still under development, there are things to further develop, e.g. currently it cannot distinguish between minor and full GC, and things like this. Also, I plan to add more features like displaying data from other kind of files from the work folder, do some automated analysis, etc. 🙂

Here is a screenshot showing memory usage data visualized based on the content of the std_server*.out files:
