What is 100% sure for me: Munin is complaining about missing rrd for field ADPS, to graph main png for the plugin, while the config of plugin does not talk about this field.

What I have found with time, but I am not 100% certain for now: this SEEMS to happen when a subgraph contains a field which has the same name as the subgraph: "multigraph edf_teleinformation_locataire42dtagedroit.adps" mentions field "adps.label ADPS"

NB: in future messages, locataire42dtagedroit will be renamed locataire42etagedroit.

Issue persists even after changing adps.label ADPS to adpss.label ADPS. Where is the dep tree stored ?

I have found a similar case. This plugin conf:

                echo "multigraph weather_wtrr_villers"
                echo "graph_title Weather wtrr_villers";
                echo 'graph_vtitle °C';
                echo "graph_args --base 1000";
                echo "graph_category weather";
                echo "temp_min.label Min temperature";
                echo "temp_max.label Max temperature";
                echo "alarm.label Alarm (no data)"
                echo "alarm.critical 0.5"

                echo "multigraph weather_wtrr_villers.temp"
                echo "graph_title Temperature";
                echo "graph_info Values are read from the website ${weather_wttr_villers_URL}"
                echo 'graph_vtitle °C';
                echo "graph_args --base 1000";
                echo "graph_category weather";
                echo "temp_min.label Min temperature";
                echo "temp_max.label Max temperature";

                echo "multigraph weather_wtrr_villers.rain"
                echo "graph_title Rain";
                echo "graph_info Values are read from the website ${weather_wttr_villers_URL}"
                echo 'graph_vtitle mm';
                echo "graph_args --base 1000";
                echo "graph_category weather";
                echo "rain.label Rain";

                echo "multigraph weather_wtrr_villers.wind"
                echo "graph_title Wind";
                echo "graph_info Values are read from the website ${weather_wttr_villers_URL}"
                echo "graph_vtitle km/h";
                echo "graph_args --base 1000";
                echo "graph_category weather";
                echo "wind.label Wind";

                echo "multigraph weather_wtrr_villers.visu"
                echo "graph_title Visibility";
                echo "graph_info Values are read from the website ${weather_wttr_villers_URL}"
                echo "graph_vtitle km";
                echo "graph_args --base 1000";
                echo "graph_category weather";
                echo "visibility.label Visibility";

randomly produces this error (note that it randomly complains alternately between rain and wind):

... once again, it looks like munin has troubles when a field has the same name as a plugin.

Note that in the present case, all sub-plugins were graphed correctly; the graph that was not drawn was the parent image on main page.

Initially, a previous version of the plugin was working fine, with same sub-plugins names, but different field names. Plugin broke after changing echo "humidity.label Rain"; into echo "rain.label Rain";

In other words, renaming a field in a sub-graph to give it the name of the sub-plugin itself ... broke the parent image.

I am not creating a different bug report because I believe it's the same root problem.
