Hi, I have a custom script that is working fine and graphing with no problems when I have the test launch interval set to 5m but if I change this to 10 or 15m then the graph stops updating,
This is due to the way that the rrd-files are created. An rrd file has a "step" setting telling RRD what the normal update-interval is for the graph; if updates don't arrive with the expected interval, it will consider the data to be stale/invalid and not show any graphs.
The default for RRD-files generated by Xymon is to get updates in 5 minute intervals.
To fix this you should define the RRD in the "rrddefinitions.cfg" file and specify a different update interval. If you update it once every 15 minutes = 900 seconds, then you can copy most of the default setup in that file, and just change the interval. Like this:
[sfap/900] RRA:AVERAGE:0.5:1:576 RRA:AVERAGE:0.5:6:576 RRA:AVERAGE:0.5:24:576 RRA:AVERAGE:0.5:288:576
Note that this is only used when the rrdfile is created - it cannot be changed later. So you will have to delete your current sfap.rrd files and have Xymon re-create them with the new "step" value. You can use the command "rrdtool info ~xymon/data/rrd/HOSTNAME/sfap.rrd" to see what the step value is.
