Advanced xymondboard query

Hi, thanks for your reply.
I understand now that xymondboard is no meant to present performance data.
So I will have to read the values from RRD files.

Is there a way to have a list that matches services with their associated
rrd files?
For example:
linux04;cpu=/home/xymon/data/rrd/linux04/la.rrd
linux04;memory=/home/xymon/data/rrd/linux04/memory.actual.rrd,/home/xymon/data/rrd/linux04/memory.real.rrd,/home/xymon/data/rrd/linux04/memory.swap.rrd
checkmk;conn=/home/xymon/data/rrd/checkmk/tcp.conn.rrd
...

Is that information spread in some cfg files?

Kind regards
Enzo

Actually, I should add, you don't necessarily need the source code to the
service to add ncv collection as that reference suggests - merely a way of
extracting performance data from it.  You can then write a simple script to
reformat that as ncv.

xymondboard is meant for getting summary information suitable for a

data from Xymon it needs to be logged to Xymon in the first place.
Services tend to have different ways of extracting performance data (when
there is a way), so yes, it is pretty much dependent on each service.
However, a lot of services are network server services, so a tcp query may
be able to make the service do some work, and the time to respond to that
query may infer how quickly the service is able to respond to other
queries.  TCP response times are in the rrd files available on the trends
status page.  But every service is different, so you are best off checking
what is available, or can be built into, or can be monitored via an add-on
script, for the specific services you are hoping to see performance data
for.  If you can add features to the service (you have the source code),
you could make it write ncv to a text file and get those sent to Xymon, or
send the data directly from the service.  Ref:

Hello! I am new to Xymon and I am trying to extract xymon's data from
command line.

What I need: extract from Xymon list of services with the following
fields:
Host;ServiceName;ServiceStatus,ServicePerfValue(if
applicable);ServiceOutputText
For example:
localhost;bbd;green;;OK - bbd is ok.
localhost;cpu;green;0.23;OK - cpu is ok.
localhost;memory;yellow;0.85;WARNING - memory is 85%.
...

So far, I found xymon command and xymondboard subcommand:
# /home/xymon/server/bin/xymon 127.0.0.1 "xymondboard
fields=hostname,testname,color,line1"
checkmk|trends|green|
checkmk|info|green|
checkmk|http|green|green Thu Jan 31 12:09:41 2019: OK
linux04|trends|green|
linux04|info|green|
linux04|clientlog|green|
linux04|memory|green|green Thu Jan 31 12:09:41 -03 2019 - Memory OK

My problem: I cannot find a way to extract performance data from
services. I tried reading RRD files, but I cannot find a general
association rule between services and rrd files. It seems it is pretty much
dependent of each service.

How is the best way to do this?

Kind regards
