Some of the dagman log messages in dagman.out file were updated to have HTCondor instead of Condor. This breaks the monitord parsing regex's and hence it won't be able to parse information from the dagman.out file.

Karan,
The "Condor" -> "HTCondor" change is from a while ago (8.5.0). I guess I probably wouldn't have changed it at that point if I knew that you guys were still reading dagman.out (I thought you had switched over to using jobstate.log).
Basically, if there was Condor in a string that was just something informational generated by DAGMan, it's now HTCondor. But things like paths, binary names, config macros, etc., don't have the "HT".
