# Project observability

> Source: https://docs.strapi.io/cloud/projects/observability

The Observability tab surfaces usage metrics, endpoint traffic, and infrastructure health data directly from your project dashboard. Use it to monitor API and bandwidth consumption, identify high-traffic endpoints, and track CPU and Memory usage over time.

The *Observability* tab is accessible from your project dashboard. It contains 4 sections: [Summary](#summary), [Project consumption](#project-consumption), [Traffic insights](#traffic-insights), and [CPU and Memory usage](#cpu-and-memory-usage).

## Summary

The *Summary* section displays a monthly overview of your resource consumption and any overage charges.

Use the month picker in the top-right corner of the section to view previous months.

The section contains 4 metric cards:

| Card | Description |
|------|-------------|
| API requests | Total API requests for the month, shown against your plan limit with a progress bar. Displays overage charges if the limit was exceeded. |
| Asset bandwidth | Total bandwidth consumed for the month, shown against your plan limit with a progress bar. Displays overage charges if the limit was exceeded. |
| Asset storage | Storage used per environment. Each environment shows a progress bar with its usage against its limit. Displays overage charges if the limit was exceeded on any environment at any point throughout the month. |
| Overage charges | Total overage amount for the month, excluding applicable taxes. |

API requests data is available in real time, whereas Asset bandwidth and Asset storage are updated hourly. To update these metrics, refresh the dashboard.

## Project consumption

The *Project consumption* section shows API requests and asset bandwidth usage over time, broken down by environment.

Use the time range selector in the top-right corner to adjust the period displayed:

| Time range | Plan availability |
|------------|-------------------|
| 24h | All plans |
| 7d | All plans |
| 14d |   |
| 30d |   |
| 60d |  |

The section contains 2 charts:

- API requests: total API calls across all environments, displayed as a stacked bar chart.
- Asset bandwidth: total data transferred for assets across all environments, using the same stacked bar format.

Each bar represents a time bucket (hourly or daily, depending on the selected range) and is stacked by environment. Hover over the chart to see a tooltip showing the consumption breakdown per environment at a specific point in time. To filter out environments from the graph, click on their name in the legend.

## Traffic insights

The *Traffic insights* section shows which API endpoints and assets generate the most traffic for the selected environment and time range.

Use the *environment* dropdown and the time range selector to filter the data. The available time ranges are the same as in [Project consumption](#project-consumption).

### Top endpoints by API traffic

The *Top endpoints by API traffic* table lists the 5 API endpoints that received the most requests in the selected period.

| Column | Description |
|--------|-------------|
| Endpoint | The matched API route path. |
| Requests | Total number of requests in the selected period. |
| P50 (ms) | Median response time. 50% of requests completed faster than this value. |
| P95 (ms) | 95th percentile response time. 95% of requests completed faster than this value. |
| P99 (ms) | 99th percentile response time. 99% of requests completed faster than this value. |
| Max (ms) | The highest single response time recorded in the selected period. |
| Error rate (%) | Percentage of requests that returned a 4xx response. |

### Top assets by bandwidth usage

The *Top assets by bandwidth usage* table lists the 5 assets that consumed the most bandwidth in the selected period.

| Column | Description |
|--------|-------------|
| Asset path | The file path of the asset. |
| Total bandwidth | Total data transferred for this asset in the selected period. |

## CPU and Memory usage

The *CPU and Memory over time* section shows your application's CPU and Memory consumption as a percentage of the available resources.

The section displays a single area chart with 2 series:

- CPU: displayed as a blue dashed line
- Memory: displayed as a green solid line

Use the *environment* dropdown to select which environment's metrics to display and the time range selector to adjust the period. Hover over the chart to see a tooltip showing the CPU and Memory values at a specific point in time. Data is displayed hourly or daily, depending on the selected range.

Click the refresh button () in the section toolbar to manually load the latest data. The section also refreshes automatically:

- Every 30 seconds for the 5m and 15m ranges
- Every 5 minutes for the 1h, 24h and 7d ranges
