## Properties

| Property | Value |
|---|---|
| Access | Public |

## Events published

- `OnRegisterTelemetryLogger()` (integration): Allows 3d party extensions to register their own telemetry loggers to be used with Telemetry codeunit. Is used in conjunction with .
  - subscribers: [Codeunit 8713 "System Telemetry Logger"](../codeunit/8713.md) OnRegisterTelemetryLogger

## Procedures

- `Register(TelemetryLogger: Interface "Telemetry Logger")`: Registers a telemetry logger from a 3d party extension. Is used in conjunction with
- `GetTelemetryLogger(Publisher: Text; var TelemetryLogger: Interface "Telemetry Logger"): Boolean` (internal): Get the telemetry logger from publisher. If there are multiple telemetry loggers registered for the current publisher, a warning is logged.
- `GetRelevantTelemetryLoggers(ExcludePublisher: Text): List of [Interface "Telemetry Logger"]` (internal): Gets the relevant telemetry loggers based on the CallerCallStack, doesn't include the ExcludePublisher's logger.
- `SetCallStackPublishers(Publishers: List of [Text])` (internal)
- `Register(TelemetryLogger: Interface "Telemetry Logger"; Publisher: Text)` (internal)

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 8709 "Telemetry Loggers Impl."](../codeunit/8709.md) (4 calls: `GetRelevantTelemetryLoggers → GetRelevantTelemetryLoggers`, `GetTelemetryLogger → GetTelemetryLogger`, `Register → Register`, …)

## Called by

- [Codeunit 8712 "Telemetry Impl."](../codeunit/8712.md) (4 calls: `LogMessageInternal → GetRelevantTelemetryLoggers`, `LogMessageInternal → GetTelemetryLogger`, `LogMessageInternal → OnRegisterTelemetryLogger`, …)
- [Codeunit 8713 "System Telemetry Logger"](../codeunit/8713.md) (1 call: `OnRegisterTelemetryLogger → Register`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC25

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Telemetry Loggers")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
