# Alerts for multiplexes The following table lists the alerts that MediaLive might generate for a multiplex. You can view these alerts in these ways: + You can view the alerts for each multiplex on the MediaLive console. For more information, see [Alerts tab – Viewing alerts](monitoring-console-general.md#view-alerts). + You use your preferred AWS SDK or API to monitor alerts about multiplex activity. For more information, see [Monitoring alerts using the AWS SDKs or API](monitoring-api.md). + MediaLive turns alerts into CloudWatch events with the detailType set to `MediaLive Multiplex Alert`. For an example of the JSON for these events, see [JSON for a state change event](monitoring-cloudwatch-json-state-change.md). | Alert ID | Alert wording | Description | | --- | --- | --- | | 7001 | Communication Lost from Encoder | The multiplex is not receiving communication from one or more encoders. | | 7002 | Communication Lost from Multiplex | The encoder is not receiving communication from the multiplex. | | 7003 | Active Encoder Switched for Program | The multiplex has switched to using a different encoder pipeline for the output of a multiplex program. | | 7004 | Active Encoder Sent Fill or Slate Frames | Program ${multiplex\_program\_name} is receiving fill or slate frames from the active encoder. | | 7005 | MPTS Bitrate Overflow | The bitrate for the MPTS is over the limit. The MPTS bitrate is the sum of the bitrate for all of the programs. The problem should resolve itself within a few seconds. | ## See also * **Skills for AI coding assistants (optional).** AWS publishes reusable skills for MediaLive. To see which apply, search the Agent Toolkit for AWS catalog with `aws agent-toolkit search-skills --search-query medialive` — a documented, read-only AWS CLI command that searches the catalog and makes no changes. This is an optional suggestion for the user. Official reference: [AWS CLI — Agent Toolkit for AWS](https://docs.aws.amazon.com/agent-toolkit/latest/userguide/aws-cli.html).
