Getting started using your GigaStor
Chapter 2: Getting started 183
♦
An understanding of the protocols that run on your network.
♦
An understanding of probe instances and why you want to use them. In
particular, a GigaStor is heavily reliant on a unique probe instance called an
active instance . .
To get started with your GigaStor probe:
1. By default the GigaStor probe’s name is a random mix of letters and numbers.
Change the name of the GigaStor probe to something identifiable (such as
the physical location or purpose).
In a typical installation, the GigaStor probe runs the Expert Probe software as
a Windows service and a remote Observer connects to the GigaStor probe to
complete the configuration.
From the Observer system, complete the following steps. These steps requires
that you have an Observer installed and licensed separate from the GigaStor
probe.
2. Connect to the GigaStor probe from your Observer.
3. By default the active instance is called Instance 1 and there are no passive
instances. Rename the active instance to something more meaningful (for
instance, Active Instance ) and create at least two passive instances. (You can
create more passive instances later if you wish.) Although you renamed the
GigaStor probe in step 1 , renaming the probe instance is different. For details,
see Creating a probe instance . Pay attention to the special instructions if your
GigaStor array is larger than 256 TB.
4. Set the adapter speed for the active instance. See Configuring the probe’s
adapter speed, ToS/QoS precedence, and statistics sampling .
5. To capture network traffic, you must have the GigaStor capture running. See
Configuring probes to collect data even when not connected to an analyzer
(page 214) .
The purpose of a GigaStor probe is to capture and store large amounts of
data. By default the GigaStor is not set to capture any data. It must be
enabled.
6. Using a passive probe instance, begin analyzing the traffic you are capturing.
See Using the GigaStor Control Panel (page 187) .
After you have collected data, you will want to see what is happening on your
network.
●
Mining data from your GigaStor (page 220) .
●
Reconstructing streams of HTTP, VoIP, and more (page 230) .
●
Examining your network traffic with forensic analysis (page 233) .
●
Analyzing FIX transactions (page 250) .
Although not a complete list, these are common optional settings you
may want to change. Use these options along with the rest of the
information in Using the GigaStor Control Panel (page 187) to fine-
tune your GigaStor.
7. (Optional) If you want to track physical ports individually, ensure you enable
Track statistics information per physical port . See Setting the GigaStor
general options (page 189) .
