because dbcp2 uses commons pool2, so I believe yes.all the common metrics of commons pool will be exposed, like For the metrics specific to dbcp, like |

Is there a non-JMX way to register these?

Other ways are not always possible as far as I know, because libraries using commons-pool2(like jedis or dbcp2) keeps the pool objects as internal properties, and we cannot get them.
and commons-pool exposes JMX, so using JMX seems to be a natural fit.

I agree JMX as the default is a good idea. I was more curious if there was a way if we did have access to the pool directly. I used commons pool in some of my own code and didn't have JMX enabled at the time. It would be nice to offer a way to still gather those metrics if posssible.

As we can see from the following code, JMX registration in commons-pool2 is enabled by default , unless you configure to disable it explicitly, which I don't think a serious application should do.

Please use dot separated names like max.borrow.wait.time, which will be camel-cased by certain NamingConvention implementations. By keeping dot-separated names in the core code, we maximize the portability of the metric to many different monitoring systems.

@jkschneider thanks for pointing it out, fixed in 32c5c0d

@chao-chang-paypay is this PR considered finished? Can I help you somehow? I'm actually looking forward to this update 👍 |

Thanks for the hard work on this @chao-chang-paypay. I can see that this was a non-trivial implementation, and you did a fantastic job on it! Polished a bit and merged with 2f7f51b. |

I already see these code in branch Master，but can not find tnem in the latest release version. What's the problem? and i can not wait anymore. |
