ComSunAppservMonitorTestpublic final class ComSunAppservMonitorTest extends com.sun.enterprise.management.support.ComSunAppservTest | Unit test for the com.sun.appserv monitoring MBeans relied
upon by AMX. |
| Fields Summary |
|---|
| private static final Set | COM_SUN_APPSERV_MONITOR_TYPEStypes to be tested as in "category=monitor,type=xxx". We can't just test all
category=monitor, or even check that getStatistics() and getStatisticNames()
are present, as many such MBeans don't work at all.
Types taken from com.sun.enterprise.management.support.initMap(). |
