The number in rrdfeed.txt might be in the in-memory RRD buffer. Check the timestamp on the RRD file and see if it's older than that of rrdfeed.txt. From my experience, it seems that if you display the graph in Xymon, the buffer gets flushed and you can then get up-to-date data from the RRD file.

Does it have data in it? So something like this should show the last 50 data points:

rrdtool fetch xymonnet.rrd AVERAGE | tail -50

did not know of the fetch option. It does not have any data, only ``nan'' s. Thanks for pointing that out.

I removed xymonnet.rrd and restarted xymond_rrd.

So I sent a USR2 signal on xymond_rrd and in last 1 hr only see these few lines about xymonnet

$ grep xymonnet /var/log/xymon/rrd-status.log (sanitized)

17859 2013-01-23 22:23:59 xymond_rrd: Got message 9941 @@status#9941/ xymon.example.net|1358997839.782880|192.168.0.53||xymon.example.net |xymonnet|1358999639|yellow||yellow|1341079916|0||0||1358997660|linux|xymon|0| 17859 2013-01-23 22:23:59 Creating rrd /home/xymon/data/rrd/ xymon.example.net/xymonnet.rrd 17859 2013-01-23 22:23:59 RRD create param 01: '/home/xymon/data/rrd/ xymon.example.net/xymonnet.rrd' 17859 2013-01-23 22:24:08 Flushing cache '/xymon.example.net/xymonnet.rrd' 17859 2013-01-23 22:24:08 Flushing '/xymon.example.net/xymonnet.rrd' with 1 updates pending, template 'runtime'

Added this /tmp/rrddump.sh as --processor=/tmp/rrddump.sh to the xymond_rrd in tasks.cfg file

#!/bin/sh cat >/var/tmp/rrdfeed.txt exit 0

And only seen this line in long time

$ grep xymonnet /var/tmp/rrdfeed.txt runtime 1358998632:792.73 xymon.arl.qwestip.net xymonnet

It created a xymonnet.rrd file with only ``nan'' s. I should have at least seen this number above

So am I hitting a bug? I am using 4.3.10

On my system, the last dozen or so were "nan", probably due

to buffering. But you should see something if it's all working OK.

Hi

I am not getting any graph for xymonnet. I am running xymon 4.3.10

I do have a xymonnet.rrd file

-rw-r--r-- 1 xymon xymon 20K 2013-01-23 14:49 xymonnet.rrd

It's name is runtime and type is GAUGE per rrdtool dump

When I tried to draw a graph it did not like GAUGE type.

# rrdtool graph /tmp/test.png DEF:p1=xymonnet.rrd:runtime:GAUGE LINE2:p1#ff00ff ERROR: Unknown CF 'GAUGE' in 'DEF:p1=xymonnet.rrd:runtime:GAUGE'

So I changed it to AVERAGE type, but the graph is empty.

# rrdtool graph /tmp/test.png DEF:p1=xymonnet.rrd:runtime:AVERAGE LINE2:p1#ff00ff481x149

# ls -lh /tmp/test.png -rw-r--r-- 1 root root 6.1K 2013-01-23 15:18 /tmp/test.png

# display /tmp/test.png shows empty graph.

What gives?
