Turns out in further investigations with IBM VSAM support, that catalog file extents can also reside on other data spaces than on the one catalog was initially created.
Consequences:
- no need to leave out monitoring of datasets with ATTRIBUTE=USERCAT
- also, file usage statistics is show for all dataspaces, even though for the initial catalog dataspace it is pathological (always usage=100%)

There was also a bug in space numbering, which showed up if a volume contained more that one data spaces.

Both changes in HOBVSEDU.REXX are now committed in trunk.

For those pathological spaces: they can be hided on the Xymon server side, putting IGNORE for those "partitions" in analysis.cfg.
That recommendation will still be added in the manual.

Looking more into it, it seems that the IDCAMS/LISTCAT report contains an error in ATTRIBUTES.
If the catalog space is defined in a volume along with data spaces and the volume is not the first candidate volume in the catalog, IDCAMS/LISTCAT reports attribute value USERCAT for both dataspaces in the volume, also for the data space which is wrong.
This error does not seem to exist if the catalog space is in the first candidate volume, though.
Needs to validate the conclusion more, and if it is correct, VSAM lab should correct the IDCAMS/LISTCAT code.

This concerns the VSE client.

There seems to be a bug in parsing IDCAMS/LISTCAT output, so that as we have our big VSAM catalogs xxnCAT data space defined in volumes xxn001, xxn002, ..., xxn0NN, and xxn003 always contains the catalog file, for some reason data space utilisation of the volume xxn003 is not received by the Xymon server.
