## What does this dashboard tell me?

The Cache Performance dashboard lets you see at a glance the value of your Apigee Edge cache.
The dashboard helps you visualize the benefit of the cache in terms of lower latency and reduced
load backend servers.


> [!NOTE]
> **Note:** **Data delay interval**   
> After API calls are made to proxies, it may take up to **13 minutes** for the data to appear in dashboards, custom reports, and management API calls.

For information about cache management, see [Creating and editing an environment cache](https://docs.apigee.com/api-platform/cache/manage-caches-environment).

## What does this dashboard measure?

| Metric | Description |
|---|---|
| Average cache hit rate | The rate of calls hitting the cache measured against total API traffic. |
| All cache hits | The sum of calls that hit the cache. |
| Cache hits by app | Sum of calls hitting the cache broken down by developer app. |
| Average time with cache | The average amount of time for an API call when it hits the cache. |
| Average time without cache | The average amount of time for an API call when it does not hit the cache. |
| Cache improvement | Compares the average time with cache and average time without cache, giving you an idea of the overall effect of the cache on API performance. |

## What else do I need to know about this
dashboard?

You can measure cache performance for all API proxies in your organization, or you can select
individual ones.

This dashboard uses standard controls, like the date and data aggregation selectors, hovering
over graphs for more context, exporting data to CSV, and so on. To learn more, see
[Using the analytics dashboards](https://docs.apigee.com/api-platform/analytics/using-analytics-dashboards).

> [!NOTE]
> **Note:** The performance ratios may appear incorrect for the first few minutes for new data. This is because with a small number of data points, there can be a difference in the number of data points being compared to create the ratios. This inconsistency will resolve itself within a few minutes as it collects more data points. If the performance ratios still appear incorrect, refresh the page.
