There are a number of things that you'll need to consider before you dive in to monitor your network devices, such as resource pool design, firewall rules to be configured, management packs to be deployed, and user role requirements.
In the Deploying UNIX/Linux agents section of Chapter 4, Deploying Agents we showed you how to create a resource pool for cross-platform monitoring. You'll need to create additional resource pools when designing a network monitoring architecture for your OpsMgr environments, to ensure optimal performance and scalability.
For example, if you have a large number of network devices to be monitored, it's recommended that you assign a resource pool that includes management or gateway servers that will be specifically responsible for monitoring those devices. In this way, you can control the OpsMgr servers that are to be used to monitor agents and the ones that are exclusively monitoring your network devices.
