Hello,

I have an extension script called "send" that produces output
containing "seconds: <foo>", which I pass through the NCV handler to
create a graph. This works fine.

The problem comes when I add a link to the graph to the end of send's
output. It looks similar to <a href="http://$BBDISP/hobbit-cgi/stuff">.
The graph appears on the test page, but data stops being collected, and
rrd-status.log fills up with errors:

2005-09-30 03:30:42 RRD error creating
/var/lib/hobbit/rrd/host/send.rrd: Duplicate DS name: http

I tried adding "http:NONE" to NCV_send in hobbitserver.cfg, and I tried
replacing the colon in "http://" with %3A. Both actions changed the
errors to this:

2005-09-30 03:44:39 RRD error creating /var/lib/hobbit/rrd/host
/send.rrd: Duplicate DS name: 127001hobbitcgihobb

Is there a better way to get the NCV handler to ignore the colon in
http://? I'm running the snapshot from 21 Sep 2005 right now.

Thank you!

Matti
