Up to 5,000 (10,000) Monitored Computers

This is a typical scenario for PerformanceGuard installations that should monitor up to 5,000 computers. It can be used for monitoring up to 10,000 computers, but don't use it for more than 10,000 computers.
You'll need:

One server hosting the entire setup, including:
- PerformanceGuard frontend server
- PerformanceGuard backend server
- PerformanceGuard web server
- SQL databases

Depending on how many PerformanceGuard agents you plan to install, your server should meet the following minimum requirements:

Up to 10,000 Monitored Computers

This is a typical scenario for PerformanceGuard installations that should monitor up to 10,000 computers. Unlike the previous scenario, this scenario involves using two separate servers: one server for hosting PerformanceGuard services and another server for hosting the databases.
You'll need:

One server for hosting:
- PerformanceGuard frontend server
- PerformanceGuard backend server
- PerformanceGuard web server
One server for hosting SQL databases

Depending on how many PerformanceGuard agents you plan to install, your application server should meet the following minimum requirements:

20,000 or More Monitored Computers

This is a typical scenario for PerformanceGuard installations that should monitor 20,000 or more computers.
You'll need:

For every 10,000 computers: one server for hosting the PerformanceGuard frontend server
Example: If you are going to monitor 30,000 computers, you'll need three frontend servers.
Separate frontend servers should always use separate databases.
One server for hosting the PerformanceGuard backend server and the PerformanceGuard web server
One server for hosting SQL databases
