[Xymon] "ports" RRD graph is often flaky.

Replying to myself (sure sign of insanity):

I may have actually figured out why this happened, looking for confirmation.

Here's part of the analysis.cfg config for this host:

  PORT "LOCAL=%([.:]80)$" state=ESTABLISHED min=0 color=red track=http
"TEXT=Web connections"
  PORT "LOCAL=%([.:]8009)$" state=ESTABLISHED min=0 color=red track=ajp
"TEXT=AJP connections"
  PORT "LOCAL=%([.:]8777)$" state=ESTABLISHED min=0 color=red
track=mule_aps "TEXT=MuleAPS connections"
  PORT "LOCAL=%([.:]8443)$" state=ESTABLISHED min=0 color=red
track=mule_nwsi "TEXT=MuleNWSI connections"

All four of these lines have been in the config for a long time, but the
mule_aps and mule_nwsi tracking identifiers *used* to be ajp, the same
as the 8009 port line.  So I had three lines all using "ajp" as the
tracking ID.

I'm guessing that what I used to have is a misconfiguration, and I'm
lucky that I got *anything* at all.  I'm hoping that now I will have no
problems.

Thanks,
Shawn
