Hi Arvind, May I ask what Serviceability Agent tools / API (which you want to survey) means? I think that it includes jdb, jinfo, jmap, jstack and Dynamic Attach.
If this is right, my answers are below. 2016-06-29 1:15 GMT+09:00 Arvind Aprameya <arvind.apram...@oracle.com>: > · Have you been using Serviceability Agent related API's or tools > for any of your debugging or analysis purpose (e.g. core dump / heapdump ) ?

I'm one of OpenJDK technical support engineers in Japan. I used hard these tools for troubleshooting many times. For example of corner case, I wrote a reproducer of jvm networking bug by using jdb. https://bugs.openjdk.java.net/browse/JDK-8151212 (reproducer-raw.txt) http://icedtea.classpath.org/people/ykubota/fixLoopAtJMXConnectorFactory/file/e31044f0804f/testProgram/src/main/java/debugcontrol/DebugController.java#l114 In addition, Yasumasa and I developed HeapStats [1] which aims to improve after-the-fact analysis by using JVM TI agent for collecting java runtime information. HeapStats uses socket to AttachListener to get thread dump. [1]: http://icedtea.classpath.org/wiki/HeapStats/ > · Do you believe the current capabilities of SA are helpful / > important ? Exactly. > · Areas of improvement you would like to see / make in future ? By jdk9, we will use jcmd / jhsdb instead of jstack / jmap. I think it's a right way. I want to contribute serviceability groups as possible as before. > Please share your responses as replies to this thread on the > serviceability-dev list or to me directly until 12th July 2016. > > Thanks for your time in advance . > > > > thanks & regards, > > Arvind Thanks, Yuji
