I'm feeling rather dopey at not being able to figure this out, but bear with me.
I'm trying to define a regex that will match, among other things, a line that begins with: netmon- and any number of characters that follow it, and then ends with my domain name. The two I need it to match right now are: "netmon-int.umdnj.edu" and "netmon-ext.umdnj.edu" but there may be others going forward.
Here is my example:
%(bbdisplay|xymon|katahdin|^netmon-*).umdnj.edu
I was suspicious of the ^, so I tried removing it -- no change. So far I've tried this list of things:
%(bbdisplay|xymon|katahdin|netmon-*).umdnj.edu %(bbdisplay|xymon|katahdin|^netmon\-*).umdnj.edu %(bbdisplay|xymon|katahdin|netmon\-*).umdnj.edu
...maybe one or two others. When I try either of the two hostnames I'm trying to match with pcretest, I get "No match". Can anyone point me in the right direction? It's surely something simple.

That matches netmon followed by zero or more dashes. You probably want:
%(bbdisplay|xymon|katahdin|^netmon-.+)\.umdnj\.edu

Indeed I do! Thank you! Did not realize that the */+ modifiers refer to the thing immediately before them.

this should catch it
%netmon-.*

Careful not to confuse globbing with regex
%(bbdisplay|xymon|katahdin|^netmon-.*).umdnj.edu
You were almost there. * means to match the previous character 0 or more times
. is any character, so .* is match any character 0 or more times.
.+ would be to match any character 1 or more times
This is different than globbing, where * means any character 0 or more times.
Common mistake for those not familiar with the intricacies or regex vs globbing.
