Input plugin lifecycle

As explained in Logs and Telemetry

An input plugin lifecycle is the ordered sequence of registration, initialization, event handling, cleanup, and exit stages for an input plugin.

An input plugin lifecycle organizes a plugin into registration, initialization, input handling, cleanup, and exit stages. Each stage communicates success or failure through defined return codes. section 10.6.2

Implement the stages in operational order:

  • Register the plugin name and description so help output and configuration references can discover it. section 10.6.2
  • Initialize by retrieving configuration, optionally logging debug settings, validating required values, caching valid parameters, and returning an appropriate status. section 10.6.2

How Logs and Telemetry covers it

How deep it goes
Explains each lifecycle stage through implementation responsibilities and Go callbacks, but does not detail the complete input encoding body.
Examples
Uses Go implementations for registration, initialization, input handling, cleanup, and exit, plus a return-code table.
What it assumes
Assumes familiarity with Go callbacks, plugin configuration, and communication with controlling C code.
What you can do after
Build it from scratch by implementing lifecycle callbacks, validating configuration, caching state, emitting records, and returning plugin statuses.
How it connects
Connects plugin registration with configuration, validation, caching, callbacks, return codes, querying, sequencing, and record encoding.
