Greetings. I would like to query the CurrentThreadsBusy MBean and am running into issues creating a JSP page for that query.
The questions I have are: (1) when does one use "get" vs "qry". For e.g., the following URLs work: CurrentThreadsBusy -> http://localhost:8090/manager/jmxproxy?qry=Catalina:type=ThreadPool%2Cname=%22http-apr-8453%22 CurrentThreadsBusy -> http://localhost:8090/manager/jmxproxy?qry=Catalina:type=ThreadPool,name=%22http-apr-8453%22 HeapUsed -> http://localhost:8090/manager/jmxproxy/?get=java.lang:type=Memory&att=HeapMemoryUsage&key=used But these ones do not: CurrentThreadsBusy (using get) -> http://localhost:8090/manager/jmxproxy?get=Catalina:type=ThreadPool%2Cname=%22http-apr-8453%22 CurrentThreadsBusy (using get) -> http://localhost:8090/manager/jmxproxy?get=Catalina:type=ThreadPool&name=%22http-apr-8453%22 I get: ----- Error - javax.management.RuntimeOperationsException: Exception occurred trying to invoke the getter on the MBean ---- (2) The following manager/busythreads.jsp does not work: ----------busythreads.jsp:--- <jsp:forward page="/jmxproxy/"> <jsp:param name="qry" value="Catalina:type=ThreadPool" /> <jsp:param name="name" value="%22http-apr-8453%22" /> </jsp:forward> ----end of busythreads.jsp---- I get: ---- OK - Number of results: 0 ---- while this one, heapused.jsp, works fine: -------heapused.jsp:----- <jsp:forward page="/jmxproxy/"> <jsp:param name="get" value="java.lang:type=Memory" /> <jsp:param name="att" value="HeapMemoryUsage" /> <jsp:param name="key" value="used" /> </jsp:forward> ------end of heapused.jsp------ I would appreciate pointers on fixing "busythreads.jsp". Thanks. -Shanti
