capabilities plugin¶

The capabilities plugin collects platform capabilities decoded from hardware subsystems, for example from SMBIOS using dmidecode. The static platform data is exposed through a micro embedded webserver and returned by the plugin in json format.

Synopsis¶

 <Plugin capabilities>
   Host "localhost"
   Port "9104"
 </Plugin>

Host - Bind to the given interface/address. By default, if option is not set, the plugin will bind to the "any" address, i.e. accept requests sent to any of the hosts interfaces/addresses. This option is supported only for libmicrohttpd newer than 0.9.0.

Port - Port the embedded webserver should listen on. Defaults to 9104.

Caveats¶

Accessing the stats¶

The capabilities plugin doesn't operate like a regular read plugin. Since it exposes static information, there is no need to constantly sent the information to collectd. The information is exposed through a webserver and available by cURLing the Host:Port from the configuration. Examples:

curl localhost:9104

curl 10.237.214.26:50123
