Observer Apex : Observer Apex : Installing and upgrading : How to install Apex : Understanding your deployment strategy
Understanding your deployment strategy
To use Apex effectively, you must understand how you have data sources deployed in your network.
 
Where you install Apex, Observer Suite, and probes will depend on the size and traffic levels of your network. In general,high-traffic installations should have a dedicated Apex system, resulting in a three-tier distribution of Apex functionality:
Apex
Observer Suite analyzer(s)
Probe instances that actually collect the data
We highly recommend that any probe, Observer Suite, or Observer Infrastructure (OI) be installed on a system with a static IP address. Having a dynamic address may cause confusion with reports should the address for a system change. It becomes very difficult to correlate problems or history when addresses change.
Tip! Create a unique probe instance on every probe that will be used for the sole purpose of collecting network trending data for Apex and call it “Apex instance.”
 
 
Example 1. For larger networks or heavier traffic
For larger networks, or networks with heavy traffic,Apex can be installed on a different system than the Observer analyzer used to collect network trending statistics. This forms a three-tier collection and reporting hierarchy with probes passing information to Observer and Observer passing information to Apex.
 
Example 2. For smaller networks or lighter traffic
For smaller networks, or networks with light traffic, the Apex appliance has Apex and Observer Suite pre-loaded to form a two-tier collection/reporting hierarchy.
