|
|
|
varnish_devicedetect - Plugin to graph the device usage ratio of
|
|
website visitors
|
|
|
|
=head1 APPLICABLE SYSTEMS
|
|
|
|
Servers running varnish, and using the "varnish-devicedetect" VCL
|
|
(https://github.com/varnish/varnish-devicedetect)
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
The plugin runs "varnishlog", and graphs the last 5 minutes of log
|
|
entries.
|
|
|
|
This configuration section shows the defaults of the plugin
|
|

|
|
|
|
=back
|
|
|
|
The "devices" list is a space separated list of devices, which should
|
|
match the headers set by the varnish-devicedect VCL.
|
|
|
|
=head1 INTERPRETATION
|
|
|
|
This plugin reads data from the Varnish shared memory log, and
|
|
presents a stacked percentage graph of the device types of your
|
|
website visitors for all entries present in the log, for the last 5
|
|
minutes.
|
|
|
|
The percentage shown per device is that of all devices, not just the
|
|
ones specified by env.devices.
