Case sensitivity in bb-hosts service name
We're seeing the following behaviour in Hobbit version 4.1.2p1 on OpenBSD 3.8 GENERIC.MP#298 i386:
A 'service' was created on an existing host using a lower case name, eg. xyz, by sending a 'status' event to the hobbit server.
Subsequent status events are being sent using upper case 'XYZ', but being assigned to the history for the lower case service, 'xyz'. When searching for Reports->Event Log Report->Tests to match=xyz, the original (lower case) and subsequent (upper case) events are shown in the resulting events with the lower case name.
A dot has been added to the bb-hosts config for a page using the service name 'XYZ', but the dot does not appear. When changing the name in the bb-hosts config to be 'xyz', the dot does appear. Unfortunately, for cosmetic and consistency reasons, we would like it to be upper case.
It seems the case sensitivity is not being carried through to service name parsing in the bb-hosts file. Can someone advise if this is a bug or a known 'feature'?
Also, suggestions are welcome for a workaround. We've tried using server/bin/bb 127.0.0.1 "rename HOST xyz XYZ", also ... "drop HOST xyz", also ... "rename HOST xyz xyz-1". None of these seem to get rid of the 'xyz' service and allow us to replace it with an 'XYZ' service.
thanks,
Richard

Yes, that is a bit tricky. Internally, Hobbit ignores upper/lower case on all kinds of names - whether names of hosts or columns. But it does preserve the case when building the status view.
The way to do this is to shut down Hobbit, and then edit the ~hobbit/server/tmp/hobbitd.chk file replacing the string "|xyz|" with "|XYZ|" throughout the file. When you restart Hobbit it will pickup these tests as having the name "XYZ", so regardless of whether your tests send in a status for "xyz" or "XYZ" they will show up with the upper-case setting that Hobbit picked up from the checkpoint file.
Note that this also affects the files and directories where the history for these events are stored. Unix filesystems are generally case-sensitive, so to implement this renaming fully you may need to manually rename some of the files in the ~hobbit/data/hist/ directory as well as the "xyz" directory in ~hobbit/data/histlogs/HOSTNAME/ .
