|
|
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!
