Download Message IDs for Troubleshooting


Use the operational metrics on the Analytics page of the Alexa developer console to troubleshoot smart home and video skill failures and latency issues that might impact customers. From the Capability Directives page, you can download message ID logs to view the latency and success rate metrics by capability interface. For details about these metrics, see Operational metrics.

Learn how to download and view your message IDs and associated metadata to gain visibility into causes of failures and insight to help you debug skill issues.

Define filter criteria

You can select or enter the following filter criteria for your message IDs:

  • Timeline (Required) – Gives a starting time and a duration for applying the search filter. The 20 most recent message IDs are available for download for a given timeline.
    • Start Time (UTC) – The starting UTC timestamp to apply to the search filter for message IDs.
    • Duration – Select the duration to use to calculate a window for the time line. Valid values: 5 minutes, 10 minutes, 15 minutes, 30 minutes, 45 minutes, 1 Hour.
  • Response Type (Required) – Select the type of responses to include in your search results:
    • Skill Failure – Requests to a skill categorized as failures.
    • Skill Success – Requests to a skill categorized as successes.
    • Invalid Request – Invalid requests to a skill.
    • All – All requests to the skill.
  • Capability (Required) – Select at least one capability from the list of all capabilities supported by the skill to include in the search results.
  • Directive (Required) – Select at least one directive from the list of all directives supported by the skill to include in the search results.
  • Error Type/Exception (Optional) – Select at least one error type or exception from the list to include in the search results.
    • Error Type – Choose from a subset of the most frequently seen Error Types. If you leave this field blank, the search downloads the top 20 message IDs associated with all Error Types and the supported subset of Exceptions. For a comprehensive list of Error Types and their descriptions, see the Alexa.ErrorResponse Interface reference.
    • Exception – Exceptions occur on the Alexa side after Alexa attempts to process the response from your skill. The following subset of Alexa exceptions are available:
      • SKILL_RESPONSE_TIMEOUT_EXCEPTION – Exception thrown when a skill times out on an Alexa request to the skill.
      • INVALID_SKILL_RESPONSE_EXCEPTION – Exception thrown when Alexa receives an invalid response from the skill.
  • Latency Threshold (ms) (Optional) – Specify a latency threshold in milliseconds to filter your search results by response latency. Only message IDs with latencies greater than or equal to the threshold are available for download.

About the message ID log file

The downloaded message ID log file is a CSV file with the top 20 message IDs that match the filter criteria. You can open the downloaded file in a spreadsheet editor.

The log file contains the following fields:

  • Timestamp(UTC) – Time in UTC format that the user invoked the skill.
  • Skill ID – Alexa skill ID for the skill.
  • Skill Stage – Specifies whether the skill is in development or production.
  • Region – Region where the user invoked the skill.
  • CapabilityAlexa interface associated with the skill invocation.
  • Directive – Alexa directive that invoked the skill. For more details about capability directives, see the documentation for each interface that your skill supports.
  • Request Message ID – Message ID associated with the request.
  • Success FlagTRUE indicates that the skill request was a success; FALSE indicates that the skill request failed.
  • Latency(ms) – Number of milliseconds until Alexa receives a response from the skill after Alexa sends a directive to the skill.
  • Error Type – Error thrown by the skill, if applicable. For a complete list of Error Types, see the Alexa.ErrorResponse Interface.
  • Exception Name – Alexa-side exception, if applicable. Supported exceptions for the Message ID logs are SKILL_RESPONSE_TIMEOUT_EXCEPTION and INVALID_SKILL_RESPONSE_EXCEPTION.

About the issue log files

You can troubleshooting latency and success rate performance issues by viewing the logs for issues that occur for a specific country or device type. Use the message ID logs to troubleshoot capability directives used in your skill.

Message ID log file

The message ID log file is a CSV file with one row for each message that exceeds the baseline. You can open the downloaded file in a spreadsheet editor.

The summary log file contains the following fields:

  • Date – Date and time in UTC format during which the issue occurred for the specified message ID.
  • Directive NamespaceAlexa interface used in the request.
  • Directive Name – Alexa directive that invoked the skill. For more details about capability directives, see the documentation for each interface that your skill supports.
  • Country – Country where the user invoked the directive.
  • DeviceType – Type of device.
  • Latency(ms) – Number of milliseconds until Alexa receives a response from the skill after Alexa sends a directive to the skill. Available for latency issue logs only.
  • Success Rate – Indicates whether the directive request succeeded or failed. Available for success rate issue logs only.
  • MessageId – Message ID associated with the request from Alexa.

Summary log file

The summary log file is a CSV file with one row for a combination of device type, country, and directive statistic, aggregated hourly. You can open the downloaded file in a spreadsheet editor.

The summary log file contains the following fields:

  • Date – Date and time in UTC format during which the issue occurred. The time indicates the start of the hour.
  • DeviceType – Type of device.
  • Country – Country where the user invoked the directive.
  • Directive Stat – Directive name and percentile statistic, such as P99, P90, and P50. Percentile (P) indicates how a value compares to others within the same period. For example, P90 is the 90th percentile and means that 90 percent of the data within the period is lower than this value and 10 percent of the data is higher than this value.
  • Latency(ms) – Number of milliseconds, averaged across all directives in the hour, until Alexa receives a response from the skill after Alexa sends a directive to the skill. Available for latency issue logs only.
  • Success Rate – Percentage of directives that succeeded in the hour. Available for success rate issue logs only.
  • Baseline – For latency: The baseline latency in milliseconds for the given percentile statistic. Amazon recommends a maximum latency of 1000 milliseconds for P90 and 800 milliseconds for P50 percentile.
    For success rate: The baseline success rate percentage. Amazon recommends a success rate of 97 percent.
  • Diff – For latency: The difference in milliseconds between the actual latency and the baseline.
    For success rate: The percentage difference between the actual success rate and the baseline.
  • Affected Utterances – Number of utterances that whose latency or success rate exceeds the baseline.
