Zenoss ZenTech Community

We have been on Zenoss Resource manager 4.3.5 for a few years and every once in a while I inadvertently click on "Dynamic View" when looking at a device. 100% of the time, it generates the following error message: "Error with zenjserver, please check log for errors."
there are no errors in the zenjserver log when I look at it via the Advanced > Daemons page. The little documentation I can find just shows what it is supposed to look like, but nothing on what, if any, configuration needs to be done to actually get it to work. It's never been that important to us, but mainly due to the fact that it has never, ever, actually shown us any data or graphics!

Did you verify zenjserver is running on the RM?

And you verified this using the command line, not the webUI?

Try stopping, verifying, then starting? I have never seen this daemon not work before.

What Zenoss ver? Also, what java ver?

It's been stopped and restarted dozens of times since 2014, and Dynamic View has never worked, ever.
We are running Enterprise Resource manager 4.2.5, revision 724

Attach the log file for review

Check out the zenjserver.conf to obvious issues as well.

This interface won't let me upload/attach files. I get this error: Must be a supported file. Unable to upload
My files are named zenjserver.log and zenjserver.conf What's wrong with those names or file types?

FYI, as I stated in my original post, there are no errors of any kind in the zenjserver.log. Just start and stop messages
Okay, I renamed these 2 files to *.txt and they now upload. copy-of-zenjserver.txt is the .conf file and zenjserver.txt is the log file.

Do you run zope (zenwebserver) on the same server as zenjserver?

Also, lets put zenjserver into debug

logseverity 10 in the conf

then restart and try to access something and see if any more detailed info shows up.

Also, try:

telnet 127.0.0.1 8700

All Resource Manager components run on the same vm. Impact runs on its own vm.

telnet 127.0.0.1 8700
Trying 127.0.0.1...
Connected to 127.0.0.1.
