|
upnpc_ - Plugin to monitor routers via UPnP
|
|
|
|
This plugin uses the upnpc utility (package miniupnpc in Debian), to monitor an
|
|
router using UPnP. It can monitor the following aspects, and plot them as separate graphs:
|
|
* uptime: how long the link has been up;
|
|
* bitrate: the up and downlink bitrate (e.g., sync speed for DSL);
|
|
* traffic: the actual up and downstream traffic rate;
|
|
* pkts: the number of packets coming in and out.
|
|
|
|
=head1 APPLICABLE SYSTEMS
|
|
|
|
Linux systems with upnpc installed.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
None needed.
