Expert Probe Software

Observer needs a probe to capture network traffic. The probe can be local to Observer Analyzer or remote.

Introducing Probes
Discover the basics of probes, probe instances and what type is right for you, and how probes work with switches.

How a probe uses RAM

A Windows computer uses Random Access Memory (RAM) as a form of temporary data storage. Windows separates all available memory into three sections: protected memory, user memory, and reserved memory. An Observer probe, depending on how it is configured, uses these types of memory differently.


Understanding the Packet Broker Integration tab

When using network packet broker integration, you can dynamically reduce traffic flow to your GigaStor when it is at risk of oversubscription giving you the content you need. Additionally, metadata tags identify the network segment where the packets came from, providing you context when troubleshooting.


Using the Probe

The probe has two interfaces: the probe service and the analyzer user interfaces. You can switch between the two depending on what you want to accomplish. Also learn about monitoring a wireless access point (AP) and where to enable network trending.


Using the NetFlow features in Observer

Watch a video about NetFlow in Observer, and see a list of some important NetFlow considerations to know.


How to assign physical ports to probe instances


How to install or upgrade the software

This section describes the installation process and minimum requirements if you are installing Observer or probe on your system. This applies to physical and virtualized servers. If you virtualize the server, each server must meet these specifications.


How to allocate the reserved RAM

After you have the RAM reserved for Observer, you must allocate it for the probe instances. Here are our basic recommendations for allocating the memory. These are just recommendations and may be changed or modified for your circumstances.

Creating a NetFlow collector or NetFlow Trending collector

There are two types of NetFlow collectors in Observer. Choose the correct one for your needs, or create two different probe instances—one for the NetFlow collector and another for the NetFlow Trending collector.
