[Xymon] flushing rrd files - now possible via rrdcached

[Martin Sperl]

No – 2 different places needed a change:

·         Template support when using rrdcached (essentially translating templates to full updates)

·         RRDCACHED_STRIPPATH support to strip the “leading” path making it a relative path which is supported by rrdcached (besides when using sockets)

RRDCACHED_ADDRESS already existed as a transparent option.

These obviously could also get patched with xymon, but as this also is beneficial for other tools (cacti,…) I decided to patch rrdtool.

One note though: rrdtool in the master branch comes with a new feature called “skip-past-updates” (rrdrool update -- skip-past-updates …), this remains unsupported when using rrdcached.

Ciao,
                Martin

This is very cool.  What were the changes?  Was it to support the RRDCACHED_* variables?
