cannot update RRD using "data $MACHINE.trends"

6 Jun 2013


      I am using xymon 4.3.11.   I sent data to multiple RRD files in one data
message from the xymon client, but these data are not updated in the RRD
files in the xymon server.   Any suggestion how to update multiple RRD
files in one data message?
In the client side, I sent 2 values to each of the 2 RRD files.
...
cat /tmp/test.data
[Test1.rrd]
DS:value1:GAUGE:3600:0:U 101
DS:value2:GAUGE:3600:0:U 102
[Test2.rrd]
DS:count1:GAUGE:3600:0:U 201
DS:count2:GAUGE:3600:0:U 202
...
xymoncmd xymon $XMON_IP "data ct6-metrics.localdomain.trends cat /tmp/test.data"
In the server side, /var/log/xymon/rrd-data.log shows the RRD files are
created.  But all the values in both RRD files are 0.  Subsequent data
message sent using different data does not change anything in the RRD files.
