Viewing errors

This guide shows you how to filter and view errors with the Error Reporting console.

Getting started

To see your errors, open the Error Reporting page in the Google Cloud Console. A list of recently occurring errors, in order of frequency, is displayed:

The user interface showing the error list.

Error Reporting interface

Errors are grouped and de-duplicated by analyzing their stack traces. Error Reporting recognizes the common frameworks used for your language and groups errors accordingly. For more information, see How errors are grouped.

Each error entry provides a summary that helps you determine when the application started to produce the error, how often it occurred, and how recently it occurred.

Error Reporting samples up to 1,000 errors per hour. When this limit is reached, the displayed counts are estimated. If too many events are received for the whole day, Error Reporting can sample up to 100 errors per hour and continue to extrapolate the counts.

You can filter, sort, and view additional details about errors, as well as restrict the errors that appear in the list to a specific time range.

Error Reporting list

On the Error Reporting list page, the following information is provided for each reported error:

Column Description
Resolution Status A workflow status assigned at the error-group level. Status options are: Open, Acknowledged, Resolved, and Muted. You can change resolution status from the list page.
Occurrences The number of times this error has occurred in the selected time range.
Users The number of users affected by this error in the selected time range. The column is hidden if no user information is available.
Error Provides the error information, as extracted from the error's stack trace. The error message and its code location are displayed. If your code is available in Cloud Source Repositories, clicking the code location brings you to your source.
Seen in Lists the service and version in which the error is occurring.
First seen The time at which this error first appeared.
Last seen The time at which this error last occurred.
Response Code The HTTP status code returned with this error.

Error Details page

To view detailed information about an error group, click any entry that appears in the Error Reporting list to show the Error Details page:

The user interface showing the error details view.

On this page you can examine information about the error group, including the history of a specific error, specific error instances, and diagnostic information contained in samples for the error.

Sample errors are found in the Recent samples panel. Each sample represents one occurrence of the error and includes a parsed stack trace.

Viewing associated log entries

To view the log entry associated with a sample error, click View logs from any entry in the Recent samples panel. This takes you to the Logs Viewer in the Cloud Logging console.

You see that the search-query box is pre-populated with the filter for the current error group and, below that, the list of log entries contributing to that error group:

Note that the error_group filter works only in the Logs Viewer; it doesn't apply, for instance, when creating log export sinks or metrics.

For more information on using the Cloud Console to view these logs, go to Viewing logs.

Filtering and sorting

Filter, sort, and restrict the types of error groups that appear in the list page or details pages. There are several ways to filter your errors from these pages.

Selecting time range

The time-range menu lets you restrict the error groups that you see to the previous 1 hour, 6 hours, 1 day, 7 days, or 30 days.

Sorting

From the Error Reporting list column headers, you can sort the following information:

  • Occurrences: Sorting on this column lets you see the most frequently occurring errors.
  • First seen: Sorting on this column helps you find the newest errors.
  • Last seen: Sorting on this column helps you see which errors are still occurring. You can also reverse sort to see which errors have stopped.

Text matching

Use the Filter errors text field to filter the list of displayed errors. This field performs a text match on the Error information, the HTTP Response Code, the exception stack, and the following attributes:

  • Request URL
  • Report location (that is, the location where the error was logged)
  • HTTP method

On the Error Reporting list page, the bar graph under the Occurrences column updates to show filtered results in blue, versus the non-filtered total in grey:

You can view the bar graph, in detail, on the Error Details page in the Errors section.

Actions

Other actions to help you view your errors are:

  • Link to issue / View issue: These options are accessed from the bug icon next to each row in the list:

  • Auto reload: Reloads the list every 10 seconds.
