# Viewing content quality analysis settings and alerts
<a name="content-quality-analysis-viewing"></a>

When you enable content quality analysis, MediaConnect starts posting warnings and alerts for the enabled metrics in your AWS account. 

This page guides you through the process of confirming your content quality analysis settings, and viewing any warnings and alerts for the flows in your account. 

## Prerequisites
<a name="content-quality-analysis-viewing-prerequisites"></a>

The following procedure assumes that you have already enabled content quality analysis for a flow.

## Procedure
<a name="content-quality-analysis-viewing-procedure"></a>

You can view content quality warnings and alerts through the AWS Management Console, the AWS CLI, and the MediaConnect API.

------
#### [ Console ]

**To check if content quality analysis is enabled**

1. Open the MediaConnect console at [https://console.aws.amazon.com/mediaconnect/](https://console.aws.amazon.com/mediaconnect/).

1. From the **Flows** screen, select the flow you want to inspect.

1. On the flow details page, choose the **Configuration** tab.

1. Under **Source monitoring configuration**, you can find the content quality analysis state.

**To check if quality alerts are present**

1. Open the MediaConnect console at [https://console.aws.amazon.com/mediaconnect/](https://console.aws.amazon.com/mediaconnect/).

1. From the **Flows** screen, select the flow you want to inspect.

1. On the **Alerts** tab, alerts appear when content quality problems are detected in the flow source.

------
#### [ AWS CLI ]

To confirm if quality analysis metrics are enabled for a given flow, run the [describe-flow](https://docs.aws.amazon.com/cli/latest/reference/mediaconnect/describe-flow.html) command:

```
aws mediaconnect describe-flow --flow-arn flowARN
```

The response shows which content quality analysis metrics are enabled:

```
{
    "Flow": {
        "FlowArn": "flowARN",
        ...
        "SourceMonitoringConfig": {
            "ContentQualityAnalysisState": "ENABLED",
            "AudioMonitoringSettings": [
                {
                    "SilentAudio": {
                        "State": "DISABLED",
                        "ThresholdSeconds": 15
                    }
                }
            ],
            "VideoMonitoringSettings": [
                {
                    "BlackFrames": {
                        "State": "DISABLED",
                        "ThresholdSeconds": 10
                    },
                    "FrozenFrames": {
                        "State": "ENABLED",
                        "ThresholdSeconds": 5
                    }
                }
            ]
        },
        ...
    }
}
```

The response also shows messages about any warnings or alerts that need your attention:

```
{
    ...
    "Messages": {
        "Errors": [
            "Monitoring Stream Alert: Audio Stream Missing. Please investigate the flow source.",
            "Monitoring Stream Alert: Video Stream Missing. Please investigate the flow source."
        ]
    }
}
```

Alternatively, if both audio and video streams are present but experiencing issues, you might see something like this:

```
{
    ...
    "Messages": {
        "Errors": [
            "Monitoring Stream Alert: Black frames detected for more than 30 seconds. Please investigate the flow source.",
            "Monitoring Stream Alert: Frozen frames detected for more than 30 seconds. Please investigate the flow source.",
            "Monitoring Stream Alert: Silent audio detected for more than 30 seconds. Please investigate the flow source."
        ]
}
```

**Note**  
These error messages are context-dependent. If an audio or video stream is missing, related quality alerts for that stream (such as silent audio or black/frozen frames) won't be triggered.

If you no longer want to analyze content quality for your flow, you can disable the feature. For instructions, see [Disabling content quality analysis](disable-content-quality-analysis.md).
