## Definition

* **Type:** Method

```csharp
public int GetSessionMetaDataCount(Guid id, int tag)
```

### Parameters

**** (\[Guid]\(https\://learn.microsoft.com/dotnet/api/system.guid)): Unique identifier associated with the data.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Data stream index.

### Returns

| Type                                                       | Description                       |

| [int](https://learn.microsoft.com/dotnet/api/system.int32) | Returns count of metadata chunks. |

### Remarks

Use the *GetSessionMetaDataCount* method to retrieve the total number of metadata arrays available in the session this frame occurred in. Profiler data can contain frames from different sessions.

When there are multiple [Profiler.EmitSessionMetaData](/engine/6000.0/script-reference/unityengine/profiling/profiler/emitsessionmetadata.md) calls in the same frame, it results in multiple metadata arrays that are associated with the frame for a given *id*, *tag* pair. This information can be used to write data to the stream in small portions, which reduces the amount of memory needed to hold generated data.

Use *id* to identify the metadata from your project or package.

Use *tag* to distinguish between different data streams.
