# AsyncReadManagerSummaryMetrics > A summary of the metrics collected for AsyncReadManager read operations. ## Definition * **Type:** Class * **Namespace:** [Unity.IO.LowLevel.Unsafe](/engine/6000.0/script-reference/unity/io/lowlevel/unsafe.md) * **Assembly:** UnityEngine.CoreModule ```csharp public class AsyncReadManagerSummaryMetrics ``` ## Remarks Get a summary of the current metrics by calling [AsyncReadManagerMetrics.GetCurrentSummaryMetrics](/engine/6000.0/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagermetrics/getcurrentsummarymetrics.md). This function summarizes all metrics recorded since you started metrics collection or last cleared your metrics data. Get a summary of an existing set of [AsyncReadManagerRequestMetric](/engine/6000.0/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagerrequestmetric.md) records by calling [AsyncReadManagerMetrics.GetSummaryOfMetrics](/engine/6000.0/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagermetrics/getsummaryofmetrics.md). You can get these records by calling [AsyncReadManagerMetrics.GetMetrics](/engine/6000.0/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagermetrics/getmetrics.md). In both cases, you can filter the data with [AsyncReadManagerMetricsFilters](/engine/6000.0/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagermetricsfilters.md) in order to focus the summary on the particular categories of data you want to analyze. Additional Resources: [AsyncReadManagerMetrics](/engine/6000.0/script-reference/unity/io/lowlevel/unsafe/asyncreadmanagermetrics.md). ## Examples ```csharp using Unity.IO.LowLevel.Unsafe; using UnityEngine; public class GetMetricsSummary : MonoBehaviour { #if ENABLE_PROFILER && UNITY_2020_2_OR_NEWER AsyncReadManagerMetricsFilters m_Filter; AsyncReadManagerSummaryMetrics m_Summary; public void Start() { // Create a filter for texture file reads that have been completed m_Filter = new AsyncReadManagerMetricsFilters(); m_Filter.SetStateFilter(ProcessingState.Completed); } public void Update() { m_Summary = AsyncReadManagerMetrics.GetCurrentSummaryMetrics(m_Filter, AsyncReadManagerMetrics.Flags.ClearOnRead); Debug.Log($"Last frame bandwidth: {m_Summary.AverageBandwidthMBPerSecond}
