System Architecture

SQL Sentry Event Manager was built to handle the largest server environments. Its lightweight polling architecture incurs minimal network and server overhead; and because there are no agents, installation and maintenance overhead is virtually non-existent.

SQL Sentry Console
The zero-configuration SQL Sentry Console mirrors your existing Enterprise Manager configuration, so you don't have to redefine all of your servers and groups.  As a result you can be up and running in a matter of minutes instead of hours or days.  You can install an unlimited number of Consoles across your enterprise, and DBAs can easily connect to multiple Event Manager installations from a single Console.

SQL Sentry Database
SQL Sentry utilizes a single SQL Server database to store collected job and performance data, as well as configuration information. For maximum fault tolerance the SQL Sentry database can be installed on a clustered SQL Server instance.

SQL Sentry Server
The SQL Sentry Server is a Windows service which handles various responsibilities, including monitoring job status and performance, generating notifications, and actively collecting job history data.  One SQL Sentry Server is required for every 50 to 100 monitored servers.

Fault Tolerant Architecture
Multiple Server services can be linked together using our own clustering technology to provide virtually linear scalability and extreme fault tolerance. If any SQL Sentry Server fails, the others automatically pick up the load in a matter of seconds, ensuring nothing is missed and notifications are always sent.

Using the concept of "Sites", Event Manager can easily be setup in geographically dispersed environments to monitor SQL Servers at specific locations and report back to the Event Manager database, minimizing network overhead.

SQL Sentry Event Connector System
SQL Sentry Event Manager seamlessly integrates external event data into calendars alongside SQL Server Agent jobs, and gives you unprecedented visibility and control over all of the events that can impact your server performance. View the Event Connector page for more info.
