=head1 NAME
fastd_ - Plugin to monitor fastd uptime, peers and traffic
=head1 CONFIGURATION
Set user and group to have access to the socket
Set path to socketfile if not /tmp/fastd.sock
[fastd_*]
user fastd
group fastd
env.socketfile /tmp/fastd.sock
=head1 USAGE
Link this plugin to /etc/munin/plugins/ with the type of graph (uptime, peers, traffic)
append to the linkname, ie: /etc/munin/plugins/fastd_peers
After creating the links, restart munin-node. Don't forget to configure the plugin!
