TEST2RRD variable too long in xymonserver.cfg file 🔗 link

Hi,


I have a lot of custom scripts  and the line of TEST2RRD is  very long, sometimes is hard to find the ncv definitions in the line.


Can I split the TEST2RRD in two o more lines?


Greetings,

It is one variable, so I think it must appear on one logical line. However, I don't see any reason you can't use line-continuation to improve the legibility. Doing so will let your content span several short visual lines in your text file.

 From the man file for hosts.cfg (the first place I looked for continuation):
"Long lines can be broken up by putting a backslash at the end of the line and continuing the entry on the next line."

I expect white space in the line to be stripped by the parser, so I'd expect to be able to insert "\" and " " characters liberally. You should be able to make your lines appear however you like.

Another option would be to use string concatenation; such as:

TEST2RRD="cpu=la,disk,inode,qtree"
TEST2RRD+=",memory,$PINGCOLUMN=tcp,http=tcp,dns=tcp,dig=tcp"
TEST2RRD+=",time=ntpstat,vmstat,iostat,netstat,temperature,apache"

Or, I do this, if you are using the Terabithia rpm (you can do this without
it but would require some extra manual setup*), add content under
$XYMONSERVER/xymonserver.cfg.d/testname that has something like the
following example for a test named "threads":


#> cat xymonserver.cfg.d/threads
GRAPHS_threads="threads"

TEST2RRD+=",threads=ncv"

SPLITNCV_threads="*:NONE,total:GAUGE,consumed:GAUGE"

this keeps everything in nice, test specific configs.

* - add the following line to your xymonserver.cfg file:
directory /etc/xymon/xymonserver.cfg.d

Yes, you can. In file xymonserver.cfg, an "includir" directive is used. For each additional test in Xymon, a seperate file is created. For instance, for the additional test named "env", there is a file called "env.cfg", containing two lines:


TEST2RRD+=",env=devmon"
GRAPHS+=",env"


Note, the use of a comma at the beginning of those symbol definitions. See the documentation of xymonserver.cfg, the paragraph named DESCRIPTION. The same trick should be usable within file xymonserver.cfg too, enabling you to split up the definition of TEST2RRD.


HTH,

Ok, this is cool. I never suspected this would work. There's that big

so it has never been clear to me what parsed these files.

Thanks,

I changed TEST2RRD in the same xymonserver.cfg with TEST2RRD+=",.." and it's working fine.

TEST2RRD="cpu=la,disk,inode,qtree"
TEST2RRD+=",memory,$PINGCOLUMN=tcp,http=tcp,dns=tcp,dig=tcp"
TEST2RRD+=",time=ntpstat,vmstat,iostat,netstat,temperature,apache"
