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
@@status#172312|1237529916.645344|xxx.xxx.xxx.xxx||hostname.domain.com|temp|1237531716|green||green|1237424990|0||0||1237529620

2009-03-20 17:18:36 RRD update param 00: 'rrdupdate'
2009-03-20 17:18:36 RRD update param 01:
'/var/lib/xymon/rrd/hostname.domain.com/temp.rrd'
2009-03-20 17:18:36 RRD update param 02: '-t'
2009-03-20 17:18:36 RRD update param 03: 'sda:sdb'
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

Thanks,
Adam
