CPU load average not being graphed for some servers

Hi all,
I'm having trouble tracking this one down. For many of my
Xymon-monitored servers I can see the graphs on the CPU load page and
they have data in them. Yet for many others the CPU graphs are empty. I
can see the graphs but there is no data.
Investigation reveals that for those servers who are missing data the
.cpu file has not been updated in months, yet when I look at the client
data available it shows the load average in the uptime section, as in:
[uptime]
5:07pm 2 users, load average: 0.53, 0.71, 0.62
which is, I believe, where Xymon gets the LA from.
The file ownership and permissions on the data/hist/*.cpu files are all
correct (hobbit:hobbit and 644 on this system), in fact the only thing I
noticed that doesn't make sense is that the data/hostdata/ directories
are not being updated for those servers that do not have the CPU graphs,
even though I can see the host data in the Xymon web pages.
Confused? I know I am.
