[Xymon] Xymon to monitor HP OpenVMS

Sun Nov 26 03:01:52 CET 2017

Just to close this case, in case it helps others using OpenVMS, it turns
out the client was an old BB client, which sent its CPU status message with
"Up since <date>" rather than "up: <days> days". The difference is that the
Xymon CPU status message parsing code expects "up: " (lower-case "up",
colon, space). The script that generates the status message was adjusted,
and the RRD file came into existence.

In summary, there were some stale rrdctl files being used by Xymon, causing
the original error message in the Apache logs. But the client was also not
100% compatible with Xymon. Both now fixed.
