Own RRD graph 🔗 link

Hi,
I try to create a custom graph in xymon.
I have  process which returns lines like:
server1: 8 processes
.
serverX: 4 processes

There are different numbers of line for different hosts.
I want to have these numbers in a graph, so firstly I defined in xymonserver.cfg:
TEST2RRD=..., sapprocs=ncv"
SPLITNCV_sapprocs="server:GAUGE"

Then in graphs.cfg:
[sapprocs]
        FNPATTERN ^sapprocs(.*).rrd
        TITLE Processes
        YAXIS Processes
        DEF:p at RRDIDX@=@RRDFN@:lambda:AVERAGE
        LINE1:p at RRDIDX@#@COLOR@:@RRDPARAM@
        GPRINT:p at RRDIDX@:LAST: \: %5.1lf (cur);
        GPRINT:p at RRDIDX@:MAX: \: %5.1lf (max);
        GPRINT:p at RRDIDX@:MIN: \: %5.1lf (min);
        GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n


I get a graph, but for some reason it doesn't look like I want. The values below the graph ( cur, max, min, avg) are all 0.0.
When I do a rrdtool dump on one of the rrd files, I get the type is "DERIVE" and not GAUGE. The values in "last_ds" are correct.

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd">;
<!-- Round Robin Database Dump -->
<rrd>
        <version>0003</version>
        <step>300</step> <!-- Seconds -->
        <lastupdate>1556000353</lastupdate> <!-- 2019-04-23 08:19:13 CEST -->
        <ds>
                <name> lambda </name>
                <type> DERIVE </type>
                <minimal_heartbeat>600</minimal_heartbeat>
                <min>NaN</min>
                <max>NaN</max>

                <!-- PDP Status -->
                <last_ds>1</last_ds>
                <value>-2.5215946844e+00</value>
                <unknown_sec> 0 </unknown_sec>
        </ds>

What did I do wrong? Or isn't this possible? In the end I would like to have these values "stacked" in the graph...

Thanks!
Jonas

I assume the "=3D" is something coming from your mail reader.  It should
obviously be "=", not "=3D".

The problem is that you are sending "server1", "server2", etc. but you are
telling RRD to only import "server" as type GAUGE, which means everything
else is type DERIVE.  What you actually want is:

SPLITNCV_sapprocs="*:GAUGE"

Which will store all datasets from sapprocs as type GAUGE.
See the xymond_rrd manpage for details.

Hi,
The "star" did it 😊

Not sure what the 3D came from, maybe cut/paste/mail...

Thanks for your help!
