There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies.

The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring.  

So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Provides long term capture and analysis capabilities.

Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features. In addition, their layer 4-7 analysis is a valuable asset to our organization.

The features that I found most useful are related to storing the data. You can save the metadata: everything from the stream, ARC, or other transactions, and then come back to it later to see what the issue was.

First of all, the ability to capture packets. It is not only for monitoring. So that is very important for a company that wants to keep an eye on the packets, the transactions, the flows, everything going down and out. 

The second one is that it's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it.

I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue. You can check all this using that Observer GigaStor.

Long-term data storage is the best feature for our organization.

All of the traffic flows through this device, so we can store the traffic and the baselines. This gives us the ability to provide service and then come back later to check exactly what happened at a particular time or period. It is a very, very helpful service.
