Userdefined graphs will, by default, use the labels from the primary component Target unless you override this. You need to make sure that your routers.cgi* directives for the userdefined graph come after the first routers.cgi*Graph definition.

The ShortLegend, LegendI/O and Legend1/2/3/4 are ALWAYS taken from the relevant component Targets, since there will be many of them. You cannot override these at userdefined-graph level as there would be no way to know /which/ to override. Similarly, the MaxBytes used to calculate percentages for a given component Target is taken from that component Target. Not all directives make sense when defined at a useddefined-graph level.

The auto-generated Incoming/Outgoing graphs are classified as userdefined graphs (techinically, it should be 'composite' rather than 'userdefined' but ihstorically theyve always been called the former) hence a default target of 'first userdefined' may well pick these. The 'first' is defined alphabetically by ShortName so if you have

routers.cgi*ShortDescription[All-Traffic]: _First Graph

then this will result in it being first alphabetically and hence chosen. You can also disable the creation of the default Inconimg/Outgoing graphs in the routers2.conf

Hey Steve, thanks for the reply.

Ok that makes sense then, thanks...

So basically for User-Defined graphs you can use any directive (with the "routers.cgi*" prefix) other than any "Legend" directives and MaxBytes because they are given to the User-Defined Graph from the first component/interface target, right?

Thanks again for your reply,
Matt

Not quite.

If you check the documentation in the doc/MRTG_INFO file, then the directives that can be used with the routers.cgi* prefix on a userdefined graph are indicated by the [G] tag. These are things that apply to the whole graph. Things that would apply to just one component line are still defined at the component Target level.
