In previous versions, ZStack Cloud has provided an O&M tool called API Inspector to monitor and display the API information associated with your operations on the Cloud. This tool helps you in troubleshoots and third-party tool debugging, significantly enhancing your O&M efficiency.

ZStack Cloud 4.8.10 makes the following enhancements on API Inspector.

Displays UI GQL Requests, SDK, and Request Logs

In ZStack Cloud 4.8.10, API Inspector provides UI GQL requests information and associations between a UI request and backend requests. By clicking Group by UI Request, you can make all backend requests grouped under the UI requests they are associated with, so as to get a clearer and more readable API view.

Meanwhile, in ZStack Cloud 4.8.10, you can view SDK information and request logs in API Inspector. The logs include zstack-ui-server.log and nginx-access.log that are associated with UI requests and management-server.log that is associated with backend requests. The log details can be presented with line breaks for readability, empowering you with more comprehensive insights into API invocation activities.

Allows You to Search Requests by Time Consumption and Request URL

In ZStack Cloud 4.8.10, you can search requests by its time consumption or URL

• Time Consumption: Enter a duration time in the filter box at the top left corner of the API Inspector panel. The system will then select and display requests whose time consumption exceed this value and requests that have not been finished.
• Request URL: Enter a keyword in the filter box at the top left corner of the API Inspector panel. The system will then select and display requests whose URLs contain this keyword.

In ZStack Cloud 4.8.10, when you perform a Change Primary Storage or Change Host and Primary Storage operation on VM instances, you can now specify the Total Migration Rate. The system limits the maximum I/O read rate of the VM instance and its attached volumes in the source primary storage. In this way, you can proactively manage and control the migration process, reducing I/O contention due to large-scale data migration and lowering the impact on business.

ZStack Cloud 4.8.10 optimizes the image transmission mechanism from the ImageStore to Ceph primary storage. After the improvement, operations such as backup recoveries and VM creations based on Ceph primary storage see an approximate doubling in speed.

ZStack Cloud 4.8.10 optimizes the snapshot deletion mechanism for Shared Block Storage. After the improvement, the snapshot deletion speed is improved by approximately three times.

In ZStack Cloud 4.8.10, a new backup chain architecture is adopted by the CDP module. With this new architecture, the CDP performance can see an increase of over a hundredfold.

In ZStack Cloud 4.8.10, you can manually cancel the process of enabling a CDP task, which gives you a more convenient and flexible using experience.

In ZStack Cloud 4.8.10, the system generates an incremental instead of a full CDP backup for a VM instance attached with a CDP task after the VM volume expansion. An incremental CDP backup means creating a recovery point whose size is equal to the volume increment. This helps reduce the backup storage utilization as well as improve the speed of re-enabling the CDP task after the expansion.
