# ServicePlatform Connector Upgrade Version 3 to 4


## Metrics TimeToBeReceived renamed to TimeToLive

In version 4, the setting to configure the maximum time to live for [Metrics messages](/platform/json-schema.md#metrics) has been renamed from `TimeToBeReceived` to `TimeToLive`. This aligns it with the naming convention of similar settings for other sections of the configuration.

<!-- snippet: PlatformConnector-3to4-TimeToBeReceived -->


```cs
var platformConnection = new ServicePlatformConnectionConfiguration
{
    Metrics = new ServicePlatformMetricsConfiguration
    {
        TimeToLive = TimeSpan.FromSeconds(60)
    }
};

endpointConfiguration.ConnectToServicePlatform(platformConnection);
```



```cs
var platformConnection = new ServicePlatformConnectionConfiguration
{
    Metrics = new ServicePlatformMetricsConfiguration
    {
        TimeToBeReceived = TimeSpan.FromSeconds(60)
    }
};

endpointConfiguration.ConnectToServicePlatform(platformConnection);
```
