Comparing software probe features
 
Single Probes are appropriate for sites with smaller administrative staffs. This type of probe communicates with only one Observer at a time.
If you have a need for multiple network administrators to view packet decodes and analysis from the same probe simultaneously, choose a Multi Probe. The Multi Probe allows you to run multiple probe instances of the probe on a single system, which means that:
You can install multiple network interface cards in a single Multi Probe system, allowing multiple “points of visibility” from that probe.
You can connect multiple sessions of Observer to the same Multi Probe system. Any Observer session can see all of the networks available on the Multi Probe. The probe instances are securely encrypted and password-protected.
Although Multi Probes behave similarly to Single Probes, the Multi Probe has a different user interface for configuring the probe.
For the highest level of distributed performance, choose an Expert Probe. An Expert Probe provides Expert Analysis and capture/decode capabilities. This saves bandwidth when performing remote expert analysis, and also allows remote decode views and expert analysis in real time.
The Expert Probe can be configured to run as an Observer when you need to perform troubleshooting from where the probe is located.

1 Buffers are sent to Observer where the decoding and analysis is performed. This is less efficient than sending the expert summary and decode packets, which is available with Expert Probe.

2 Simultaneous users are supported when each user has his own probe instance.

3 Only available on hardware probes from VIAVI.

4 Decoding and expert analysis are performed by the probe and a summary is sent to Observer reducing network bandwidth use.

5 Application Performance Analysis and Application Transaction Analysis. Applications are generally OSI Layer7 applications like HTTP, FTP, RTSP, SMB, and so on.
