Change MSE resource quotas
If your workload requires more MSE resources than the default quotas allow, you can request an increase in Quota Center.
-
Log on to the Quota Center console. In the left-side navigation pane, choose Product List > General Quotas.
-
On the General Quota Products page, under the Application service category, click MSE Microservices Governance or MSE Registry and Configuration Center.
-
On the General Quotas List page, you can view or increase resource quotas.
-
To view quotas: The Quota column shows the quota for each resource, and the Used column shows your current usage.
-
To apply for a quota increase: In the Actions column, click Apply. In the Apply for Quota dialog box that appears, set the parameters and click Confirm Change.
Note-
Quota adjustments for Nacos instances are not immediate. Ensure that the instance is in the Running state before you adjust its quota.
-
When performing instance scaling or product type conversion, monitor the corresponding quotas and adjust them if necessary.
-
For stability, the quota for the number of configurations in your existing Nacos instances is automatically adjusted to your current usage. If you need to further increase this quota, submit an application in Quota Center. Your configured quota will apply to new instances.
