Prerequisites

In order to install and use Heimdall, the following will be needed:

• A login for the database. For full capabilities, this user should have the ability to login, execute a health check query, access (or create) a schema/database of "heimdall", and have full access to this schema or database. This is used for health checking and various other features such as lag detection.
• Understanding of the configuration of the application, and how to adjust what database it points to. This varies from application to application, but a few common locations for this are:
  • The IIS configuration for a .net application, under connect strings
  • a configuration json file
  • a configuration PHP file
• Preferably a test environment to test with before going into production.
• A Linux server or Docker environment with at least 20GB of space
