I have an issue where I cannot get the correct message count from our hornetq server. I'm using several tools like Hermes, Rockeye, and a Nagios script called check_jmx.
If I open one instance of Hermes and add two messages to a topic, I can see that there are 2 messages. If I look in Rockeye properties or run check_jmx, I get the correct MessageCount=2
If I open another instance of Hermes and add one more message, the message count goes to 4 instead of three. Kinda like this:
1st instance of Hermes shows 3 messages
2nd instance of Hermes shows 1 message
There are only three messages in the topic, yet two applications (Rockeye, check_jms), return a MessageCount of 4
Just wondering if anyone could shed some light on this.
P.S. These are nonDurableSubscribers and nonDurableMessages
I can only answer you from what we report through our JMX or queues interfaces. It could be a bug on the tool you are using.
