Platform services message cannot be delivered

The Total Events (SMTT) alarm is triggered in the Grid Manager if a platform service message is delivered to an destination that cannot accept the data.

About this task

For example, an S3 multipart upload can succeed even though the associated replication or notification message cannot be delivered to the configured endpoint. Or, a message for CloudMirror replication can fail to be delivered if the metadata is too long.

The SMTT alarm contains a Last Event message that says, Failed to publish notifications for bucket-name object key for the last object whose notification failed.

For more information, see "Troubleshooting platform services" in the instructions for administering StorageGRID.
