Use the collector tool to gather and analyze output from WebSphere® Application Server.
The first step in using the collector tool on your WebSphere Application Server product is to run the tool to produce a Java archive (JAR) file as output. The second step in using the collector tool is to analyze its output. The preferred method of performing this analysis is to send the JAR file to IBM® Support for analysis. However, you can use this topic to understand the content of the JAR file if you perform your own analysis.
Wasenv.jar stands for the name of the JAR file that the collector tool creates.
