Generate Daily Usage Snapshot

If MongoDB Usage UI is set to On, you can trigger this endpoint which tells Ops Manager to:

• Generate a snapshot. This snapshot of all deployments belonging to all projects and organizations includes the current information for each mongod and mongos process:

  • memory statistics

  • date

  • organization

  • project

  • IP

  • IANA port

• Calculate assignments. This populates the assignment collection. The endpoint makes Ops Manager review the snapshot for that day and copy each process with an assigned server type. Ops Manager discovers the process's server type from its host. The host's server type could have been set in the admin page. If the host's server type was not set, Ops Manager assigns the project's default server type when the host was created to that host.

You might call this endpoint if you have no assignments in the assignments collection but want to view the MongoDB Usage Admin UI. This may happen in the following cases:

1. You enabled MongoDB Usage Data Collection but the automated job that collects the data has yet run for the first time.

2. You dropped or emptied the assignments collection.

3. You did not enable MongoDB Usage Data Collection because you wanted to collect usage data one time, not every day.
