rdhabalia commented on issue #507: Add zk-stats instrumentation to get zk-client stats URL: https://github.com/apache/incubator-pulsar/pull/507#issuecomment-314275283 > Can't the latency measurement be done in the ZK client wrapper? Latency is measured against [ZK-Client](https://github.com/rdhabalia/pulsar/blob/ce73e74e2702b32cbd9a553949017033b901e1d2/pulsar-broker/src/main/java/org/apache/pulsar/broker/zookeeper/aspectj/ClientCnxnAspect.java#L64) `org.apache.zookeeper.ClientCnxn` only. So, you mean `ClientCnxnAspect` should not be part of pulsar-broker and part of other module? > Though I don't completely understand if the AOT part is needed if we are going to wrap the ZooKeeper client class. Not, completely understand your comment. But in this PR we are loading [AOT-agent at runtime](https://github.com/rdhabalia/pulsar/blob/ce73e74e2702b32cbd9a553949017033b901e1d2/pulsar-broker/src/main/java/org/apache/pulsar/PulsarStandaloneStarter.java?utf8=%E2%9C%93#L160) because of that we don't have to define agent in jvm-args and we can test aspect with unit-test. In previous ZK-server-aspect PR, we don't have any unit-test case because we can't weave aspectj- advice in unit-test so, hard to test as well. So, do you think we should load aspectj-agent at runtime rather passing as jvm-args in zk-server AOT? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
