Hi,

I'm trying to follow the Help -> Custom Graphs instructions as follows:
I've written a script to collect data, asked hobbitclient to run it
regularly.
Checked that the data is arriving on the xymon server

Re-started the hobbit rrd processes, and eventually also re-started
xymon completely.

rrdtool dump shows this:

        </ds>

So, for some reason the values are not getting into the rrd files....

Note, I found that I previously had an entry in TEST2RRD for
temp=devmon, so I have removed that and deleted all the rrd files (for
temp) so that they would be re-created.

Could anyone advise what I might have done wrong/missed here?

Thanks,
Adam

temp=devmon, so I have removed that and deleted all the rrd files (for

In addition to the above, after enableing --debug for the rrd I get this
in the log:
2009-03-20 17:18:36 hobbitd_rrd: Got message 172312

2009-03-20 17:18:36 RRD update param 04: '1237529916:39:39'

So, to me, it looks like it should be working properly....

However, even this happens:

rrdupdate temp.rrd --template sda:sdb N:39:39
rrdtool dump temp.rrd |grep last_ds

		<last_ds> UNKN </last_ds>
		<last_ds> UNKN </last_ds>
So manually updating the RRD doesn't seem to work either....

Any suggestions would be very helpful

If you are getting rrd files, there is no need to restart xymon.

Did you have temp.*.rrd files before you made this ncv-based test? If so, they 
will be broken now (and it would have been better to use a different test 
name).

Yes, but since I wasn't getting the answer I wanted I thought I'd
re-start just to be sure :)

No, and I don't (never have) use devmon.... I can only assume it was
there by default.... I'm still getting last_ds as NaN, but the above
fetch AVERAGE looks like some sort of valid data ??
