DAS Agent instance management

Updated at:

DAS Agent organizes database instances into instance groups. You can add instances to an Agent group so that DAS Agent can perform intelligent diagnostics, performance optimization, and O&M operations on the grouped instances.

Edition comparison

The Trial Edition, Basic Edition, and Enterprise Edition of DAS Agent differ in instance management capabilities.

Edition

Instance management

Trial Edition

  • Custom Agent groups cannot be created. Only the system-preset default-agent group is available.

  • Instances in the default-agent group can be edited, but the default-agent group cannot be deleted.

  • Each user receives a free daily quota of 5,000 characters. A successful daily check-in adds 700 characters to the quota, up to a maximum of 9,900 characters.

  • When a database instance is first queried in DAS Agent, it is automatically added to the default-agent group.

Basic Edition

  • Custom Agent groups cannot be created. Only the system-preset default-agent group is available.

  • Instances in the default-agent group can be edited, but the default-agent group cannot be deleted.

  • A maximum of 10 instances can be managed.

  • 100,000 characters are included, and each user receives a free daily quota of 9,900 characters. The free quota is used first. After both the free quota and the 100,000 included characters are exhausted, additional usage is billed at CNY 0.001 per character.

Enterprise Edition

  • In addition to the system-preset default-agent group, custom Agent groups can be created to organize instances as needed.

  • Instances in the default-agent group can be edited, but the default-agent group cannot be deleted. Custom Agent groups can be both edited and deleted.

  • O&M daily or weekly reports can be enabled for individual groups.

  • The maximum number of managed instances equals the upper limit of the Enterprise Edition specification. The deduplicated total of instances across all Agent groups, including the default-agent group, cannot exceed the specification limit. For more information about Enterprise Edition specifications, see DAS Agent.
