Set java.naming.security.principal to your weblogic admin username Set java.naming.security.credentials to you weblogic admin password a typical setting would be as follows, java.naming.provider.url=t3://127.0.0.1:7001 java.naming.security.principal=system java.naming.security.credentials=weblogic Additionally, you can specify the sampling interval in seconds, the number of times and mbean's properties you want to monitor. See komuso.properties for more detailed information. Usage: Just type komuso.sh/bat to run and Samurai will log WebLogic status in CSV format. Optionally you can specify the filename to output. - most Unix (including Solaris, Linux, HP-UX, MacOSX or AIX) $ komuso.sh [filename] - Windows > komuso.bat [filename] Error handling: -java.lang.IllegalArgumentException: mbean not found [heap free:name:type:property] This means that the MBean couldn't be found. Check if the name and type are correct. -java.lang.IllegalArgumentException: property not found [heap free:name:type:property] This means that the MBean could be found, but the specified property was not found. Check if the property is exist. -javax.naming.CommunicationException. Root exception is java.net.ConnectException: t3://localhost:7001: Destination unreachable; nested exception is: java.net.ConnectException: Connection refused: connect; No available router to destination This means that the connection between the Samurai and the WLS has been lost.
