In most installations, the Controller operates in single-tenant mode. In multi-tenant mode, the Controller UI context is divided into separate accounts. Each account has its own set of users, agents reporting to it, and application monitoring configuration.

You choose the tenancy mode at installation time. You can switch the tenancy mode from single-tenant to multi-tenant mode later. It is not possible to switch from multi-tenant to single-tenant mode.

Having a single tenancy Controller is suitable for most installations. Only very large installations or installations that have very distinct sets of users may require multi-tenancy.

A summary of the differences between the modes follows:

• In multi-tenant mode:
  • You can create multiple accounts (tenants) in the Controller.
  • Each account will have its own set of users and applications.
  • The Controller login page includes an additional field where users need to choose an account to log in to.
  • Essentially, multi-tenant mode allows you to partition users and access application data in a logical, secure way.
• In single-tenant mode:
  • There is only one account (tenant) in the Controller system.
  • All users and applications are part of this single built-in account, so all users have access to all monitored Applications in this mode.
  • The account is not exposed to users in the Controller UI. The account field in the login page is omitted for single-tenant mode.
  • Use a single-tenant mode for most installations.
