DISPLAYGROUP fails in analysis.cfg

I have a xymon server running "Debian GNU/Linux 9 (stretch)" with xymon 
4.3.28-2. I'm having bad luck getting DISPLAYGROUP to work in 
analysis.cfg.  It seems to only match on the first 7 characters.

I also see this problem on "Debian GNU/Linux 8 (jessie)" with xymon 4.3.17-6+deb8u1.

Below, I've shown that the display group is set, and that the analysis.cfg 
file is being parsed correctly by xymon, yet the the svcstatus page only 
shows the shortest of the DISPLAYGROUP enabled lines.

A strange problem indeed. I've scanned the relevant parts of the code, and
it all checks out, according to my amateur knowledge of C. What you're
trying to do should work just fine.

I wonder if it's just a coincidence that your group name starts with a
7-letter word. Probably.

Perhaps you could have xymond_client run in debug mode (adding "--debug" in
tasks.cfg), and see if it shows any clues in the log.

FYI, another check the process status, without using the web interface
(lynx/curl/wget) is to use the xymon command:

$ xymoncmd
$ XYMON $XYMONCMD "query balin2012.mydomain.testnet.procs"

... (etc)

Looks like I just found my answer in the source code.  This is actually broken due to someone counting the number of characters incorrectly for a strncasecmp in client_config.c.  It's done correctly later in the same code.  This should be "13" and "15" where it's "12" and "14".


$ grep -n DISPLAYGROUP= client_config.c 466:         (strncasecmp(token, "DISPLAYGROUP=", 12) == 0)     ||
467:         (strncasecmp(token, "EXDISPLAYGROUP=", 14) == 0)   ||
667:                    else if (strncasecmp(tok, "DISPLAYGROUP=", 13) == 0) {
673:                    else if (strncasecmp(tok, "EXDISPLAYGROUP=", 15) == 0) {

Very nice detective work, Dave. Have you re-compiled with adjustments and
re-tested?

Nope.  We're running ours from Debian packages, so I'm several steps 
removed from that level of testing.  I was hoping someone would be able to 
confirm more easily.  If not, I'll work on it as time allows.

Hello

problem not solved.

I configured this setup:

hosts.cfg:

page Company some fantasy company

include /tmp/room1.cfg

include /tmp/room2.cfg

group house

include /tmp/room1.cfg

analysis.cfg:

DISPLAYGROUP=house

PROC %eecd 1 1

But it doesn’t matter what I do, all hosts are messured with “%eecd 1 1”, not just group “house”, also the hosts in /tmp/room2.cfg are affected.

So I can say DISPLAYGROUP is not working at all in analysis.cfg

In reality 300 hosts are affected.

Btw. same thing with subparent.

Also I know in version 4.3.18 in the Changelog they write something is solved with DISPLAYGROUP and analysed..but no clue if it is related to this issue:

"- xymond_client: Fix DISPLAYGROUP handling in analysis.cfg rules"

We are currently on version 4.3.28

Anyone knows about this ?

Tom
