[mrtg-developers] More patches: Include and cfg file changes

[Steve Shipway]

I'm on a roll this week... :)

More patches for MRTG in the pipeline -

1.       Add wildcard support to the Include: directive.   This is something I've wanted for years and been too lazy to submit the (small) patch required to make it work.  Routers2 already supports this :P

2.       In daemon mode, check for modifications to the cfg file, and if so, reload the configuration.  I'm still testing this one because it is potentially difficult, as MRTG makes a few assumptions that this won't happen.  I'm also using Tobi's trick of using -M rather than (time-stat()[9]) on the file age, and then $^T=time after the reload.

3.       Identify RRD 1.4.999 or later, and use the new rrdcached functions I added in the RRDTool patch if running in rrdcached/TCP mode.  This is the final hurdle to allow MRTG to run on a separate server from the RRDTool database, allowing a true distributed MRTG setup.  Some additional code now in place to prevent re-testing of remote RRD files when in rrdcached/TCP mode (as the -M test can no longer be used, of course).  Needs a bit more testing, though...

I'll be submitting these to Tobi once I'm happy they're stable.  In the meantime, I'd appreciate any feedback from the community.

Steve
