Thanks for your detailed advice, the monitor product you are talking about
is good, but our solr system is running on a private network and seems to
be unusable at all, with no single downloadable application for analyzing
specific gc logs.
For analyzing GC logs, the GCViewer app is useful. With some practice
(learning to disable irrelevent information) you can pinpoint problems.
It also compiles statistics about GC intervals, which can be very
helpful. It is an executable jar.

But I have found an even easier tool for general use:
http://gceasy.io/
I still find value in GCViewer, but most of the time the information I'm
after is provided by gceasy, and it's a lot easier to decipher.
Possible disadvantage for gceasy: it's an online tool. So you have to
copy the log out of disconnected networks into a machine with Internet
access. I don't anticipate any sort of privacy problems with them --
logs that you upload are not kept very long, and GC logs don't contain
anything sensitive anyway.
Thanks,
