NAME
App::Netdisco::Worker::Plugin - Netdisco Workers
Introduction
App::Netdisco's plugin system allows users to write workers to gather information from network devices using different transports and store results in the database.
For example, transports might be SNMP, SSH, or HTTPS. Workers might be combining those transports with application protocols such as SNMP, NETCONF (OpenConfig with XML), RESTCONF (OpenConfig with JSON), eAPI, or even CLI scraping. The combination of transport and protocol is known as a driver.
Workers can be restricted to certain vendor platforms using familiar ACL syntax. They are also attached to specific phases in Netdisco's backend operation (discover, macsuck, etc).
Application Configuration
The worker_plugins
and extra_worker_plugins
settings list in YAML format the set of Perl module names which are the plugins to be loaded.
Any change should go into your local deployment.yml
configuration file. If you want to view the default settings, see the share/config.yml
file in the App::Netdisco
distribution.
How to Configure
The extra_worker_plugins
setting is empty, and used only if you want to add new plugins but not change the set enabled by default. If you do want to add to or remove from the default set, then create a version of worker_plugins
instead.
Netdisco prepends "App::Netdisco::Worker::Plugin::
" to any entry in the list. For example, "Discover::Wireless::UniFi
" will load the App::Netdisco::Worker::Plugin::Discover::Wireless::UniFi
package.
You can prepend module names with "X::
" as shorthand for the "Netdisco extension" namespace. For example, "X::Macsuck::WirelessNodes::UniFi
" will load the App::NetdiscoX::Worker::Plugin::Macsuck::WirelessNodes::UniFi module.
If an entry in the list starts with a "+
" (plus) sign then Netdisco attemps to load the module as-is, without prepending anything to the name. This allows you to have App::Netdisco Worker plugins in other namespaces.
Plugin modules can either ship with the App::Netdisco distribution itself, or be installed separately. Perl uses the standard @INC
path searching mechanism to load the plugin modules. See the include_paths
and site_local_files
settings in order to modify @INC
for loading local plugins. As an example, if your plugin is called "App::NetdiscoX::Worker::Plugin::MyPluginName" then it could live at:
~netdisco/nd-site-local/lib/App/NetdiscoX/Worker/Plugin/MyPluginName.pm
The order of the entries is significant, workers being executed in the order which they appear in worker_plugins
and extra_worker_plugins
(although see App::Netdisco::Manual::WritingWorkers for caveats).
