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

## Properties

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

## Events published

- `OnAddCommonCustomDimensions()` (integration): Allows to provide additional custom dimensions for every telemetry message. Is used in conjunction with .
  - subscribers: [Codeunit 2301 "Tenant License State Impl."](../codeunit/2301.md) OnAddCommonCustomDimensions, [Codeunit 9034 "Azure AD User Subscribers"](../codeunit/9034.md) OnAddCommonCustomDimensions

## Procedures

- `AddCommonCustomDimension(CustomDimensionName: Text; CustomDimensionValue: Text)`: Add a custom dimension for every telemetry message. Is used in conjunction with
- `GetAdditionalCommonCustomDimensions(ForPublisher: Text): Dictionary of [Text, Text]` (internal)
- `AddAllowedCommonCustomDimensionPublisher(Publisher: Text)` (internal)
- `AddCommonCustomDimension(CustomDimensionName: Text; CustomDimensionValue: Text; 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 8707 "Telemetry Custom Dims Impl."](../codeunit/8707.md) (3 calls: `AddAllowedCommonCustomDimensionPublisher → AddAllowedCommonCustomDimensionPublisher`, `AddCommonCustomDimension → AddCommonCustomDimension`, `GetAdditionalCommonCustomDimensions → GetAdditionalCommonCustomDimensions`)

## Called by

- [Codeunit 8712 "Telemetry Impl."](../codeunit/8712.md) (3 calls: `AddCustomDimensionsFromSubscribers → AddAllowedCommonCustomDimensionPublisher`, `AddCustomDimensionsFromSubscribers → GetAdditionalCommonCustomDimensions`, `AddCustomDimensionsFromSubscribers → OnAddCommonCustomDimensions`)
- [Codeunit 2301 "Tenant License State Impl."](../codeunit/2301.md) (1 call: `OnAddCommonCustomDimensions → AddCommonCustomDimension`)
- [Codeunit 9034 "Azure AD User Subscribers"](../codeunit/9034.md) (1 call: `OnAddCommonCustomDimensions → AddCommonCustomDimension`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

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 Custom Dimensions")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
