Description

This article provides the procedure to manage Data ONTAP 8.1 AutoSupport subsystem size and time budgets.

Note: For specific AutoSupport budget guidance on clustered Data ONTAP 8.2.x/8.3.x and ONTAP 9 or higher systems, refer to KB article AutoSupport can truncate on collection or delivery.

  • AutoSupport has real-world time and size constraints. As Data ONTAP grows in functionality, so does the amount of content collected and delivered in AutoSupport messages. Certain mail servers will drop e-mail messages that have exceedingly large attachments (5MB or greater), and some Web servers have file upload size limitations, too. Users expect storage systems to be able to generate AutoSupport data quickly, with minimal impact to their data serving workflows, and with minimal bandwidth requirements. Data ONTAP 8.1 introduces AutoSupport collection and delivery budgets to help alleviate these issues.
  • Starting with Data ONTAP 8.1, the AutoSupport Collection Framework organizes all content by subsystems. AutoSupport enforces time and size limits during collection to prevent  subsystem content (i.e. commands, tables and files) from not allowing other subsystem content to be collected. If a subsystem exceeds its allotted budget, AutoSupport will halt the collection for that subsystem and move the next subsystem.
  • Once the collection is finished, AutoSupport delivery budgets control the maximum size of the resulting AutoSupport compressed payload archive. There are two delivery size limits: one for SMTP and the other for HTTP (S).
  • If the size of an AutoSupport archive exceeds this size limit, some content will be dropped. During delivery, the content gets added to the archive in the order of priority recorded in the manifest, until the limit is reached.
