问题 Is there a way to monitor CPU and memory consumption of an individual web application on a Tomcat server? I have Tomcat opening all the web applications under its JVM, so I only see one JVM and cannot monitor each web-app by itself. The web-apps are sealed WAR files and I cannot tamper with the Java code either. 回答1: Looks like the official answer (to a very similar question/suggestion) is to run multiple Tomcat instances. 回答2: What do you want to monitor in web application? Servlets, ejbs...

问题 Is there a .NET equivalent for monitoring and management - similar to JMX? 回答1: You can find a JMX port to .net in Codeplex (NetMX).

问题 I have enroll students via bulk upload process through xls document in my application. Can you explain step by step process for upload student details through xls document in Jmeter3.0. Thanks, Vairamuthu. 回答1: As far as I know JMeter doesn't supply a sampler to upload from xls directly. So I suggest to convert the input file in CSV and use the Config element "CSV Data Set Config". You can find a lot of step-by-step examples on internet. Anyway, you can read xls file using Apache Tika and

问题 I have asked a question here but I did not get an answer. Howerver, I continue my search and I found something which could please my need : " MBeanServerForwarder ". I read the official JavaDoc but it is still not clear for me.
