good day,
when i have a frontend and a backend with identical names, the frontend is omitted form the fe_* graphs, presumably because the keys are being clobbered in %v and other data structures that are used to compile stats and which are only keyed on $stat[STAT_PROXY_NAME].

i was intending to submit a PR, but part way through my edits i discovered that the changes involved more than simply updating the references to %v/%data, and are therefore a little more invasive than i initially expected.
i was basicaly refactoring %v such that the top-level key was $stat[STAT_SERVICE_TYPE], then $stat[STAT_PROXY_NAME], but i am sure that there are other valid approaches.

Hello! First of all, a great plugin that you wrote. I have started using it in my environment and must say that it is proving to be greatly helpful in getting the required statistics instantly.
Secondly, one thing I would like to highlight is that haproxyng graphs sometimes throw a 404 error on some clients, while showing up completely fine on other browsers/clients. I have followed your guide to deploy the plugin, down to the last T, but this odd behavior is showing up sometimes.
I will also attach the munin-node logs, as there are no errors in them as well

I will be thankful to you if you'll help me debug this issue. Maybe the issue lies with me, but I will be greatly thankful if you help me in this. Thanks!

Stats for multiprocess seem to use a different listen port for each.

Does this mean that haproxyng would have to be run with multiple configs for each CPU being used to properly aggregate the data from each haproxy process?

thanks in advance!

Hi

i would like to extend your readme file with some install instructions for debian. Would a pull request be approved?

Cheers

Thanks for this very usefull project.

Seems the count should start 1, or the ++$count is not working.

583 my ($count, $total) = (0,0);
584 foreach my $server (sort keys %{$data{$service}{'servers'}}) {
585 ++$count;
586 $total+=$data{$service}{'servers'}{$server}{'timing'}{'total'};
587 }
588
589 $values{$service} = ($total/$count);

Thank for the project, but it do not work for me.
