# SignpostIntervalMetric

A metric that measures the duration and count of custom signpost intervals.

## Declaration

```swift
struct SignpostIntervalMetric
```

## Mentioned in

Monitoring app performance with MetricKit

## Discussion

Discussion This metric corresponds to the MetricResult.signpostInterval(_:) case. This metric appears in both intervalEntries and stateEntries when you enable state reporting. Create signpost log handles with logHandle(category:) and wrap each custom operation with mxSignpost(_:dso:log:name:signpostID:_:_:): let networkLog = MetricManager.logHandle(category: "NetworkRequests")

func loadProfile() async {     mxSignpost(.begin, log: networkLog, name: "fetchUserProfile")     await fetchUserProfile()     mxSignpost(.end, log: networkLog, name: "fetchUserProfile") } Signpost intervals measure the duration and frequency of specific code operations, such as network requests, database queries, or image processing. State reporting complements this by segmenting MetricKit metrics by user-visible app state. This type replaces MXSignpostMetric and its nested MXSignpostIntervalData object.
