New Features

Version 5.5.0 of the Splunk Add-on for Microsoft Cloud Services has the following new features:

  • Azure Resource input enhancements:

    • Introduced the Topology and Resource Graph resource types in the Azure Resource input, to migrate the following inputs from Splunk Add-on for Microsoft Azure to Splunk Add-on for Microsoft Cloud Services:

      • Azure Topology (auto)
      • Azure Topology (manual)
      • Azure Resource Graph

      For more information, see Configure Azure Resource Input.

      Consider disabling those inputs in the Splunk Add-on for Microsoft Azure, if these resource types in the Azure Resource inputs are configured in Splunk Add-on for Microsoft Cloud Services, because they will be treated as new inputs.

    • Updated Azure Resource input APIs to their latest versions for the following resource types:

      • Public IP Addresses
      • Network Interfaces
      • Virtual Networks
      • Subscriptions

  • Storage Blob input enhancements:

    • Streamlined the file-based migration to KV Store checkpoint for the Storage Blob input by making the process sequential. This improves process flow and tracking as inputs are migrated to the KV Store first, before starting data collection. This is applicable when upgrading from versions earlier than v5.0.0.
    • Introduced a new field Skip re-ingesting blobs with unchanged size to fix the data duplication issue for the Append Blob if their size has not changed. For more information, see Configure Azure Storage Blob Input.

  • Fixed a security related issue.
