Alerts for channels
The following table lists the alerts that MediaLive might generate for a channel. You can view these alerts in these ways:
-
You can view the alerts for each channel on the MediaLive console. For more information, see Alerts tab – Viewing alerts.
-
MediaLive turns alerts into CloudWatch events with the detailType set to
MediaLive Channel Alert. For an example of the JSON for these events, see JSON for a state change event.
| Alert ID | Alert wording | Description |
|---|---|---|
| 5002 | Input Image Missing | The channel was configured with a URL to an input image (for example, an avail blanking image). The channel can't access the file. |
| 5007 | Initial Probe is Taking Longer Than Expected | The MediaLive pipeline is not yet generating output because it is waiting for an input that it can successfully decode. |
| 5008 | Input Resource is Inaccessible | The channel configuration references a resource that MediaLive can't access. The specific resource is identified in the alert. |
| 5010 | Input Removed the Active Program | The transport stream program that was in use is no longer present in the input. |
| 5012 | SCTE-35 Input Data Could Not Be Processed | MediaLive can't process the SCTE-35 data that is being received. It's possible that the SCTE-35 PTS is not synchronized with the video PTS. |
| 5101 | Audio Not Detected | The channel can't decode audio in the source. Either the active input is unavailable, or the active input doesn't contain audio, or the audio is encrypted. |
| 5102 | Audio PID Missing | The audio selector for the current input specifies a PID (as the source of the audio), but that PID doesn't exist in the input. |
| 5104 | Audio Requires Dolby E Decode | The input requires Dolby E decode, but a Dolby E decode audio track selector was not specified. MediaLive might replace the audio with silence. |
| 5201 | Video Not Detected | The channel can't decode the video in the source. Either the active input is unavailable, or the active input doesn't contain video, or the video is encrypted. |
| 5202 | Black Video Detected | Black video was detected. MediaLive might have performed an automatic input failover. |
| 5301 | HTTP Get Failed | The HTTP Get failed, so retrieval of the asset failed. Perhaps there was a network issue, or the HTTP server had a problem, or the server requires user credentials. |
| 5302 | Stopped Receiving UDP Input | A UDP input (which includes RTP, MediaConnect, and Link inputs) did not receive any packets for at least one second. |
| 5304 | RTP Header Corruption | The channel is configured to receive an RTP input, but the packets received don't conform to RTP. |
| 5305 | RTMP Stream Not Found | The channel is configured to receive an RTMP input, but the specified RTMP stream is not being received. |
| 5307 | RTMP Has No Audio/Video | The channel is configured to receive an RTMP input, but the specified RTMP stream is no longer present. |
| 5308 | RTMP Disconnected | The channel is configured to receive an RTMP input, but the specified RTMP stream has disconnected. |
| 5309 | RTMP Input Connect Failed | The channel is configured to receive an RTMP input but there was a failure to connect to the RTMP URL. |
| 5312 | HTTP Request Failed When Fetching HLS Decryption Key | Don't document. This alert can't be triggered in MediaLive. |
| 5313 | HLS Segments Could Not Be Decrypted | An HLS input could not be decrypted. Check that the key provided for decryption is correct. |
| 5314 | Input Double-Publishing Detected | Multiple source IP addresses are sending packets to the same MediaLive input. This situation typically causes decode errors. |
| 5315 | Data PID Missing | A transport stream data PID was specified in the channel configuration, but it isn’t available in the input. |
| 5316 | Input PTS Behind PCR | A transport stream input contains video and/or audio frames that are arriving too late to decode based on comparison of their PTS (presentation timestamp) to the transport stream PCRs (program clock references). MediaLive might not be able to decode the video or audio. |
| 5601 | Input Failed Over | An input has failed and the channel is configured for automatic input failover. MediaLive has switched to the other input. |
| 6001 | ESAM HTTP Post Failed | A HTTP Post to the configured ESAM server failed. ESAM is part of the SCTE 35 configuration for the channel. |
| 6002 | Failed to Open UDP Socket For Write | The channel failed to open a UDP output connection. |
| 6003 | Failed to Write to UDP Socket | The channel failed to write a UDP output packet. |
| 6005 | Failed to Create Output File or Socket | The channel failed to create an output file. |
| 6006 | Failed to Write to Output | The channel failed to write data to an output. |
| 6007 | Failed to Close or Finalize The Output | The channel failed to write data to an output |
| 6008 | Failed to Delete Output File | The Channel failed to delete an output file. |
| 6010 | Failed HTTP Post Output Request | An HTTP Post to an output failed. |
| 6015 | Failed to Get HTTP Output Token | The channel couldn't write to an output because it was unauthorized. For example, an HTTP access returned 401 (Unauthorized) or 403 (Forbidden). |
| 6028 | Failed to Validate Certificate Chain When Publishing | An HTTP write failed because the remote server's SSL certificate or SSH fingerprint was deemed not OK. |
| 6030 | The Configured TS Muxer Bitrate is Too Low | A transport stream output was configured and the bitrate specified is not sufficient to carry the video, audio, and data that need to be carried within it. The channel includes a transport stream output. The bitrate specified in the output is too low for the combined video, audio, and data. |
| 6031 | Timecode Synchronization Threshold Exceeded | The channel was configured with a TimecodeConfiguration SyncThreshold, and the output timecode was resynchronized with the input timecode. |
| 6033 | Pipeline is Paused | The MediaLive pipeline has been paused. |
| 6035 | Unable to perform requested color space conversion | The channel was unable to perform the configured color space conversion. |
| 6036 | Output is Paused | One or more outputs have been paused. |
| 6038 | Nielsen Audio Watermarks could not be initialized | Nielsen audio watermarks could not be initialized. |
| 6043 | Failed To Upload Thumbnail | Video thumbnails couldn't be uploaded. MediaLive might need access to Amazon S3. |
| 6501 | Large Upload Cache Backlog | The channel maintains a cache of files pending upload that it clears after successful delivery to the output. The cache has more files pending upload to the configured destination than expected, which might indicate a temporary network slowdown between MediaLive and the destination. Or it might indicate that the destination server is slower than expected. |
| 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 | The active MediaLive encoder for a multiplex program inserted fill frames. Fill frames might indicate input to the encoder was lost. |
| 7005 | MPTS Bitrate Overflow | More bits were generated to the multiplex then it was able to pass to its output. |
