Re: [Devmon] Graphing Interface Errors / Other tests

[Mario V. <mar...@gm...>]

Thanks for the reply.

I re-checked the config after receiving your mail and realised I hadn't
added the "*TABLE:rrd... " *section correctly in the message files.  The *.rrd
*files are now updating happily....

Yes, I get an RRD table in the html of the test, but the graphs are
still not showing - I think this must be due to my graph definitions which
I'll look at next week.


Thanks also for explaining my last question below, much appreciated.


Best regards,
Mario
