Learn how to be notified by Bugsnag using an Amazon Simple Queue Service (SQS).

The SQS plugin allows access to error and project data as soon as they are received and processed by Bugsnag. The plugin adds a message to the specified queue containing information about the event, error, project and account.

The SQS plugin can be configured to fire whenever the following triggers occur.

Event Trigger Name Description
New error firstException A new error is created from a new exception
Frequent error powerTen An error occurs frequently (i.e. 10th, 100th, and multiples of 1000)
Every error exception Everytime an exception is received
Error reopened reopened An error is automatically reopened (i.e. its unsnoozed, or reopened because the exception was received again)
Project spiking projectSpiking A spike in exception in a project has been detected
Comment added comment A comment is added to an error
Error state manual change errorStateManualChange The state of an error was manually changed by a collaborator e.g. when a collaborator marks an error as fixed

Message Truncation

Amazon SQS allows messages up to 256Kb in size (this is configurable in SQS, but we recommend using the maximum). As Bugsnag accepts payloads of up to 512Kb it may sometimes be necessary to omit some of the information to ensure it fits onto the queue.

The stacktrace and meta data elements of the message will be truncated first to try and save space, the full details can always be retrieved by using the Data Access API.

If a message had to be truncated then an attribute will be added to the SQS message Truncated: "true"

S3 Upload

Instead of truncting it is possible to specify an Amazon S3 bucket name where payloads that are larger than 256Kb will be uploaded to. The following link to those messages will be added to the SQS queue:


An SQSLargePayloadSize attribute will also be added to the message containing the size of the data saved to the S3 bucket (in bytes).

See SQS Extended Client Library for more details.
