# Codeunit 8712 "Telemetry Impl."

> Codeunit 8712 "Telemetry Impl." in System Application (System.Telemetry). 4 public procedures. Present since at least BC23, still in BC30, changed in BC25.

System Application · System.Telemetry · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/Telemetry/src/Logging/TelemetryImpl.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Access | Internal |
| Permissions | tabledata "User Personalization" = r, tabledata Company = r |

## Procedures

- `LogMessage(EventId: Text; Message: Text; Verbosity: Verbosity; DataClassification: DataClassification; TelemetryScope: TelemetryScope; CallerCustomDimensions: Dictionary of [Text, Text]; CallerModuleInfo: ModuleInfo)`
- `LogMessage(EventId: Text; Message: Text; Verbosity: Verbosity; DataClassification: DataClassification; ALTelemetryScope: Enum "AL Telemetry Scope"; CallerCustomDimensions: Dictionary of [Text, Text]; CallerModuleInfo: ModuleInfo; CallerCallStackModuleInfos: List of [ModuleInfo])`
- `LogMessageInternal(EventId: Text; Message: Text; Verbosity: Verbosity; DataClassification: DataClassification; ALTelemetryScope: Enum "AL Telemetry Scope"; CustomDimensions: Dictionary of [Text, Text]; CallerCustomDimensions: Dictionary of [Text, Text]; Publisher: Text; CallStackPublishers: List of [Text])`
- `AddCustomDimensionsSafely(CustomDimensions: Dictionary of [Text, Text]; CustomDimensionsToAdd: Dictionary of [Text, Text])`

Plus 2 local procedures.

## 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 8708 "Telemetry Loggers"](../codeunit/8708.md) (4 calls: `LogMessageInternal → GetRelevantTelemetryLoggers`, `LogMessageInternal → GetTelemetryLogger`, `LogMessageInternal → OnRegisterTelemetryLogger`, …)
- [Codeunit 43 "Language"](../codeunit/43.md) (3 calls: `AddCommonCustomDimensions → GetDefaultApplicationLanguageId`, `AddCommonCustomDimensions → ToDefaultLanguage`, `AddCustomDimensionsFromSubscribers → GetDefaultApplicationLanguageId`)
- [Codeunit 8706 "Telemetry Custom Dimensions"](../codeunit/8706.md) (3 calls: `AddCustomDimensionsFromSubscribers → AddAllowedCommonCustomDimensionPublisher`, `AddCustomDimensionsFromSubscribers → GetAdditionalCommonCustomDimensions`, `AddCustomDimensionsFromSubscribers → OnAddCommonCustomDimensions`)

## Called by

- [Codeunit 8704 "Feature Telemetry Impl."](../codeunit/8704.md) (2 calls: `LogMessage → AddCustomDimensionsSafely`, `LogMessage → LogMessage`)
- [Codeunit 8711 "Telemetry"](../codeunit/8711.md) (1 call: `LogMessage → LogMessage`)

## 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 Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
