| private javax.management.ObjectName | getOldServersMBeanObjectName()Get the ObjectName of the "type=servers" MBean, which only exists in the DAS.
// if we find the old "servers" MBean, it should only be running in the DAS.
final ObjectName pattern =

|
| public java.util.Map | getPerformanceMillis()Return a Map keyed by an arbitrary String denoting some feature. The value
is the time in milliseconds. Code should not rely on the keys as they are subject to
changes, additions, or removal at any time, except as otherwise documented.
Even documented items should be used only for informational purposes,
such as assessing performance.
// ensure that we return a copy which is a HashMap, not some other variant of Map
final HashMap<String,Long> result = new HashMap<String,Long>();
result.putAll( SystemInfoData.getInstance().getPerformanceMillis() );
