Glossary

Elastic Pool

SQL Database elastic pool is a shared resource model that enables higher resource utilization efficiency, with all the databases within an elastic pool sharing predefined resources within the same pool. The workload pattern is well defined and is highly cost-effective in multitenant scenarios. Elastic pool is best for new SaaS apps requiring database isolation among tenants, or for modernizing existing apps to SaaS.

External Procedures

An external procedure, also sometimes referred to as an external routine, is a procedure stored in a dynamic link library (DLL) on Windows or shared library under UNIX. The external procedure is registered with the base language and then invoked to perform special-purpose processing.

Because external procedures run in a process separated from the database instance, using these procedures ensures that any problems on the client side do not adversely affect the database.

Foglight Agent Manager

The Foglight Agent Manager is a client application that manages Foglight agents installed on monitored hosts. It provides a centralized communications link between the Foglight Management Server and the agents. The Foglight Agent Manager also provides a number of support services such as the ability to deploy, upgrade, and configure agents.

For further details, see the Foglight Agent Manager Guide.

Foglight Management Server

The Foglight Management Server (FMS) is the central component of Foglight. The Management Server receives information from agents and makes it available in the browser interface.

The Foglight database stores all system, application, and performance data. Over time, it becomes an invaluable source of historical information for planning future system capacity requirements and for doing point-in-time analysis.
