Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

Hi Tim, Hmmm... That is interesting. Let me try to produce a new message in activemq and see if I can see the json message body. On the other hand, the plain text message is working fine that I can see the message body. Will try another json message to verify. Regards, Samuel -- Sent from: h

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

Two different methods of viewing the message content both indicate that there's no message body? That sounds like maybe your messages don't have bodies... I'm not an expert in Camel, but I've done enough with it to believe that the method you found will capture the full message (headers and body),

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

This is exactly what I added in activemq.xml as below. It only created the header Info instead of the real message body. It looks exactly the same when I review it in activeMQ console. No detail message body. xmlns:camel="http://camel.apache.org/schema/spring";

Hi JB, I have found a article to to backup enqueued messages when you need the body of messages. https://stackoverflow.com/questions/43625848/how-to-see-dequeued-messages-in-activemq Here is what I changed in active.xml as below: xmlns:camel="http://camel.apache.org/schema/spring"; http://cam

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

Hi JB, Thanks a lot for the reply. We are thinking about the mirror queued to get all the en-queued messages from producer and not consumed it. It is working fine so far but it is kind of risky if we kept those mirror messages in activeMQ without consuming them which might crash the activeMQ serv

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

Also, to state the obvious, depending on the load on your broker this could be a massive amount of logging. Be sure you configure your logging system appropriately (log roll-over in place, a sufficiently large disk to store the volume of logs at the point where they start to roll over, etc.). Tim

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

You could write a plugin that would log the content of each message as it's received; just log it and then call the corresponding super.messageDelivered() method. Relevant information is at https://activemq.apache.org/interceptors and https://activemq.apache.org/developing-plugins. Tim On Thu, Ma

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

Not directly. You can always use advisory to be notify when a message is consumed. But again, once it has been consumed, the message is gone. Regards JB > Le 21 mai 2020 à 09:05, skao a écrit : > > Hi François, > > Thanks a lot for your reply. > > Like JB mention earlier, if the consumer de

Hi François, Thanks a lot for your reply. Like JB mention earlier, if the consumer de-queue the message and then it won't show up in kahaDB. Then there is no way for me to see the hahadb file to review the en-queue messages. I would like to see all messages even though they have been de-queued b

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

By the way, if you are using queue, a message is dispatched to one and only one consumer (that’s different for topic). So, your setup is probably not what you want. I would review your use case and setup. Regards JB > Le 21 mai 2020 à 07:17, skao a écrit : > > Hi JB, > > I would like to see

Re: How to access KahaDB db.data in activeMQ-5.15.0 ?

OK, so, regarding your use case, I don’t think it’s a good idea or require to use the exporter. Just use browse or the web console (http://host:8161/admin by default). You can see all details about messages per destination, if they are persistent or not (so in kahadb o
