Thanks Ralph. That is what I see most of the time except sometimes it
shows "ndc":"JobFetcher" where that string JobFetcher never changes
(even though we update the value in code). Since we also set
<Configuration status="WARN" monitorInterval="30">
one way to unwedge the system is to "touch" the xml file. Setting it
to $${ctx:ndc} seems to do the right thing but I am not sure why it is
flaky with ${ctx:ndc}. I'd have expected the behavior to be consistent
(whether correct or not). Couldn't figure it out by looking at the
code either.
Thanks
