Get Namespaces for a Project

Retrieve namespaces for collections experiencing slow queries on a specified host. Namespaces appear in the following format: {database}.{collection}.

Note

If you specify a secondary member of a replica set that has not received any database read operations, the endpoint does not return any namespaces.

Note

Groups and projects are synonymous terms. Your {PROJECT-ID} is the same as your project id. For existing groups, your group/project id remains the same. This page uses the more familiar term group when referring to descriptions. The endpoint remains as stated in the document.

Base URL: https://{OPSMANAGER-HOST}:{PORT}/api/public/v1.0
