I'm trying to add some code to monitor my jdbc data connection pool.
Each time a connection is requested, I have some jmx code that logs
values from the datasource mbean. I haven't done much jmx coding. So
consider me a rookie on this topic. I found some code on the web that
does pretty much what I need. The relevant part of the code:
MBeanServer server = ManagementFactory.getPlatformMBeanServer();
Set<ObjectName> objectNames = server.queryNames(null, null);
for (ObjectName name : objectNames) {
MBeanInfo info = server.getMBeanInfo(name);
if (info.getClassName().equals(
"org.apache.tomcat.dbcp.pool2.impl.GenericObjectPool")) {
for (MBeanAttributeInfo mf : info.getAttributes()) {
This code works. The problem is that I have a bunch of virtual hosts
running on the same instance of TC. So I get a bunch of matching
mbeans, apparently one for each virtual host / resource defined.
Is there any way to identify which mbean is for the datasource I
currently care about? I was hoping there would be an attribute with the
datasource name or the database name or even just some way to add a
unique identifier when I create it. But I don't see anything. I've
resorted to having maxTotal set to incrementally different values in all
of my resource statements just so I can identify the datasource I'm
looking at in the logs. But that's a hack.
Is there a better way to uniquely identify datasource mbeans in jmx?
Thx
