# Performance Advisor Returns suggested indexes and slow query data for a database deployment. Also enables or disables MongoDB Cloud-managed slow operation thresholds. To view field values in a sample query, you must have the Project Data Access Read Only role or higher. Otherwise, MongoDB Cloud returns redacted data rather than the field values. ## Operations - [Disable Managed Slow Operation Threshold](https://www.mongodb.com/docs/api/doc/atlas-admin-api-v1/operation/operation-disableslowoperationthresholding.md) - [Enable Managed Slow Operation Threshold](https://www.mongodb.com/docs/api/doc/atlas-admin-api-v1/operation/operation-enableslowoperationthresholding.md) - [Return All Namespaces for One Host](https://www.mongodb.com/docs/api/doc/atlas-admin-api-v1/operation/operation-listslowquerynamespaces.md) - [Return Slow Queries](https://www.mongodb.com/docs/api/doc/atlas-admin-api-v1/operation/operation-listslowqueries.md) - [Return All Suggested Indexes](https://www.mongodb.com/docs/api/doc/atlas-admin-api-v1/operation/operation-listsuggestedindexes.md) [Powered by Bump.sh](https://bump.sh)
