[rrd-users] rrdcached + MRTG

[José Luis Megías Martín]

Hi,

I'm trying to run 'rrdcached + MRTG', but I'm not sure if the following steps are ok:

I set RRDCACHED_ADDRESS environment variable:
  export  RRDCACHED_ADDRESS=127.0.0.1

I run rrdcached as:
  rrdcached -l 127.0.0.1 <some typical params>

but when I run mrtg, I get this error message:
  ERROR: Cannot update file.rrd with '1257937902:14296586674:19866901102' The "RRDCACHED_ADDRESS" environment variable is defined, but "dummy" cannot work with rrdcached. Either unset the environment variable or use "update" instead

It's necessary to apply some kind of patch to mrtg ?
What does '"dummy" cannot work with rrdcached' mean ?

Thanks in advance
