[Xymon] DISPLAYGROUP in analysis.cfg

[John Thurston]

I'm seeing very odd behavior with my analysis.cfg*. My xymon server is 
running 4.3.28 on Solaris 10.

What I'm seeing is that trying to define a rule with DISPLAYGROUP (or 
EXDISPLAYGROUP) does not behave as expected from the man-page.

If I have the following in my analysis.cfg:

> disk /charlie 23 33 DISPLAYGROUP=Charlie
> 
> DISPLAYGROUP=Delta
>         disk  /delta 24 34
> 
> PAGE=Foo
>         disk /foo 10 20


I get the following from     xymond_client --dump-config

> DISK /charlie 23% 33% 0 -1 red DISPLAYGROUP=Charlie (line: 373)
> DISK /delta 24% 34% 0 -1 red (line: 376)
> DISK /foo 10% 20% 0 -1 red PAGE=Foo (line: 379)
> UP 3600 -1 (line: 385)
> LOAD 20.00 60.00 (line: 386)
> DISK * 90% 95% 0 -1 red (line: 387)
> INODE * 70% 90% 0 -1 red (line: 388)
> MEMREAL 100 101 (line: 389)
> MEMSWAP 50 80 (line: 390)
> MEMACT 90 97 (line: 391)


Demonstrating that DISPLAYGROUP works when appended to a setting, but 
does _not_ work when preceding a line with a setting.  The DISK setting 
is accepted, but becomes a global value rather than applying to a subset 
of the hosts. Yet the PAGE rule does work.

I have run through many scenarios, and see that the following DO work as 
rules preceding a setting:
   HOST
   EXHOST
   PAGE
   EXPAGE
   CLASS
   EXCLASS
   TEXT
   TIME
   EXTIME
and that the following DO NOT work
   DISPLAYGROUP
   EXDISPLAYGROUP


I also see that order matters. If I move the PAGE=Foo up in the file:
> PAGE=Foo
>         disk /foo 10 20
> 
> disk /charlie 23 33 DISPLAYGROUP=Charlie
> 
> DISPLAYGROUP=Delta
>         disk  /delta 24 34

then the resulting --dump-config reveals some strange parsing:

> DISK /foo 10% 20% 0 -1 red PAGE=Foo (line: 374)
> DISK /charlie 23% 33% 0 -1 red DISPLAYGROUP=Charlie PAGE=Foo (line: 376)
> DISK /delta 24% 34% 0 -1 red (line: 379)
> UP 3600 -1 (line: 386)
> LOAD 20.00 60.00 (line: 387)
> DISK * 90% 95% 0 -1 red (line: 388)
> INODE * 70% 90% 0 -1 red (line: 389)
> MEMREAL 100 101 (line: 390)
> MEMSWAP 50 80 (line: 391)
> MEMACT 90 97 (line: 392)


Can anyone help me figure out what's going on?
Do I have my analysis.cfg syntax all wrong?
Or is there a defect in the parsing?

our clients are old Big Brother clients, so I seldom delve into this file.
