add ability to dump queue/message content to a file via JMX -----------------------------------------------------------
Key: QPID-1653 URL: https://issues.apache.org/jira/browse/QPID-1653 Project: Qpid Issue Type: New Feature Components: Java Broker, Java Management : JMX Console Reporter: Robert Gemmell Priority: Minor Fix For: Eclipse MC M5 It would be useful to be able to dump queue/message content to a file using the mangement console. Some initial discussion on the topic from partychat: (4:41:20 PM) Robbie: just considering the message/queue dump to file feature (4:41:53 PM) Robbie: i was wondering...any thoughts on the best approach for tackling binary content ? (4:42:30 PM) Robbie: since it may or may not be mixed in with plain text messages (4:43:22 PM) Robbie: i think thinking maybe go with hex output..? (4:43:32 PM) Robbie: *was thinking (4:43:40 PM) partych...@gmail.com: ["Martin"] binary file? (4:44:05 PM) Robbie: what about the text messages then ?:) (4:44:06 PM) partych...@gmail.com: ["Martin"] The Messae/queue dump feature was it to be readable? (4:44:23 PM) Robbie: hmm, good point...i just asumed so <snip> (4:45:45 PM) partych...@gmail.com: ["Martin"] Is it couple with a message/queue load? (4:45:52 PM) partych...@gmail.com: ["Martin"] s/couple/coupled/ (4:45:52 PM) partych...@gmail.com: "Martin" meant Is it coupled with a message/queue load? (4:46:02 PM) Robbie: nope (4:46:20 PM) partych...@gmail.com: ["aidan"] i would say leave the contents alone and dump the bit stream. I might have a zip or something i want to get out of the message that I don't want to de-hexify (4:46:24 PM) Robbie: i dot eall have any mroe background on it than what i just said above hehe (4:46:44 PM) Robbie: *dont really (4:47:06 PM) partych...@gmail.com: ["Martin"] I'd say dump like the MC viewer : | ASCII | HEX | (4:47:42 PM) Robbie: my original thoughts were to be putting out some of the header info, then the contents.....lather, rinse and repeat (4:47:58 PM) partych...@gmail.com: ["aidan"] the viewer is a somewhat different use case IMO (4:48:13 PM) partych...@gmail.com: ["Martin"] Take a look at the MessasgeStore Tool ... it does some thing similar.. but only dumps to the screen (4:48:37 PM) Robbie: k (4:48:59 PM) partych...@gmail.com: ["aidan"] yeah, see, in the case of the message store tool I think the intention is to get something human-readable (4:49:08 PM) partych...@gmail.com: ["aidan"] same as with view-message in the console (4:49:26 PM) partych...@gmail.com: ["aidan"] but with dump to disk you might want to do a number of things with the message (4:49:36 PM) partych...@gmail.com: ["aidan"] that require the origional message contents (4:49:49 PM) partych...@gmail.com: ["Martin"] but without a load it seems a bit odd (4:50:03 PM) partych...@gmail.com: ["Martin"] I'd expect dump , fix issue, load (4:50:09 PM) Robbie: i think maybe we need a marnie:ping to decide futher :) (4:50:24 PM) Robbie: well, load isnt out of the question, it was jsut never mentioned is all :) (4:50:24 PM) partych...@gmail.com: ["aidan"] file a jira and attach this conversation to it? (4:50:36 PM) partych...@gmail.com: ["rob"] i'd not worry about load just yet (4:50:40 PM) Robbie: k (4:50:48 PM) partych...@gmail.com: ["aidan"] load gets rather more messy (4:50:52 PM) partych...@gmail.com: ["rob"] indeed <snip> (4:51:01 PM) partych...@gmail.com: ["rob"] it breaks lots of important properties of the model as well <snip> (4:51:30 PM) partych...@gmail.com: ["aidan"] but I can see a use case of something like "i need this humongous archive out of my queue so I can put it on an ftp server" <snip> (4:51:43 PM) partych...@gmail.com: ["aidan"] and having to de-MIME it first would irritate me (4:52:00 PM) Robbie: ;) (4:52:09 PM) partych...@gmail.com: ["rob"] The most likely thing is going to be "this message keeps breaking my application" "what's in the message" "I don't know - whenever I try to get it it breaks my application" <snip> (4:52:52 PM) partych...@gmail.com: ["aidan"] rob: indeed, and if the message is a bitstream it should probably stay a bitstream <snip> (4:53:03 PM) partych...@gmail.com: ["rob"] yes - you want to have the option (4:53:22 PM) partych...@gmail.com: ["rob"] ideally we'd like to have a way to deserialize the different java message types (4:53:32 PM) partych...@gmail.com: ["rob"] you also want to get the headers - separate from the file content (4:55:07 PM) Robbie: k -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:dev-subscr...@qpid.apache.org
