Foglight for SQL Server 5.7.1 - System Requirements

Agent Manager

It is recommended to increase the max-disk-space="102400" for following settings in large environments: upstream, upstream-verified, downstream.
Network throughput measured from the Agent Manager to the Monitored host average is 0.36Mbps per SQL agent.

2 SQL PI repositories
SQL PI Repository size is 1GB on the average and up to 2GB per agent. A single SQI PI repository can store SQL PI data of up to 100 agents with SQL PI enabled.
Machine Prerequisites
•
Operating system version - Windows Server 2008 and above
•
Operating system architecture - x64
•
Agent Manager available
It is recommended that you install the SQL PI repository on a dedicated machine.

Deployment Use Cases

All in One
•
All monitoring elements reside on a single machine.
•
Recommended architecture for up to 5 SQL agents (with SQL PI). Can be considered for more as long as the sizing requirements are met.
The following diagram describes 5 SQL agents with SQL PI monitoring.
 
Distributed
•
Monitoring elements are distributed amongst different machines. Architecture can be fully or partially distributed.
•
Recommended architecture for growing environments.
The following diagram describes 100 SQL agents with the SQL PI monitoring in the most distributed architecture (preferable in large or growing environments).
