I followed the below instructions installing java-monitor.war on tomcat 7. No server telemetry in the tomcat forum, here is the error I got :

SEVERE: This probe was put on hold by the collector (redeploy to try again): There is no account for uuid <uuid> connecting from 174.29.161.217

I can PM the uuid from the error in the log file.

Ready to Get Started?

Log into Java Ranch
Download the probe by clicking the "download probe" link.
Unzip the probe.
Install "java-monitor.war" in your Java application server.
Finally return to the Tomcat forum on the Big Moose Saloon to find your server telemetry.

Dear Carol,

Hmm. You managed to unearth a bug in the Java-monitor Java Ranch integration. Thank you for taking the time to report this issue. So far we have not managed to reproduce it, but that is underway.

I have manually added your account to the database, can you please redeploy the probe to try again?

Great. Let us know what you think of Java-monitor.

My server wasn't running for very long and not much was running on it, but overall it seemed impressive.

I got to see the different reporting information including all the different graphs. I got email notifications when my server went dark. I turned the notifications off since it is just my home laptop, but noticed that there was an option to designate the "staging type" as production, acceptance, testing, development. Do the staging types affect those notifications? I plan to apply more load to my servers to get a better idea of the capabilities.


Here is one of the graphs, from the "http session" tab:

Dear Carol,

I see you discovered the "post on forum" button too. :-)

The staging types were designed to help ordering once you have a few servers. I actually never thought to mix it with notifications. What was your expectation when you looked at the staging?

By all means put more load on your server and see what the graphs tell you.

That makes sense to have that information on staging type to help find the server of interest if you have a number of them.

I had seen the configuration section previously with the adjustable notifications (when no data received for 2, 5, 20 minutes or never send any alerts). So, after I received a bunch of notifications I went right there to turn it off. As I selected "never send any alerts" I just noticed the staging and recalled that the default seemed to be production. I just wondered if that would affect the notification. So, not really any expectation. Seems fine to have them separate especially since you can see both of those selections at the same time.

Dear Carol,

Yeah. Over time I learned that different people use Java-monitor in very different ways. Now I tend to opt for simplicity instead.
