Start/Stop Packet Capture marker

When checked, saved packet capture buffers will include markers

frames

that timestamp when packet captures were started and stopped.

Wireless Channel Change

When checked, saved packet capture buffers will include markers

 

that show what channel was currently being listened to. This is

 

useful if you are using Wireless Site Survey to scan channels.

 

 

Packet Sampling

Packet sampling applies to the control panel statistical displays, not

 

saved packets. On probes connected to highly-saturated networks

 

(especially multi-port probes), sometimes it is desirable to adjust

 

the rate of statistical indexing to conserve probe processing and

 

storage resources. The default (and recommended) setting is for

 

Observer to automatically scale back the packets it uses to update

 

the console display based on system load. Alternatively, you can

 

specify a Fixed Sampling Ratio to consider when updating the

 

GigaStor Control Panel Charts and statistical displays.

Capture Indexing Information

tracking, you can conserve probe processing and espeically storage

 

resources by only indexing the information that is useful to you.

 

Of special note is the “Track statistics information per physical port”

 

option. When selected, causes the GigaStor to index the data it

 

collects by Gen2 capture card physical ports. You can then display

 

GigaStor Control Panel statistics by physical port (see the next

 

bullet item).

Stop capture when disk is full

If the previous check box is selected, you can choose this option to display, within the GigaStor Control Panel, statistics sorted by Gen2 Capture Card physical port. This is useful, for example, when you want to troubleshoot the individual links without having to load the capture buffer by clicking Analyze.

When activated, the GigaStor stops capturing packets when the disk array is full. The default behavior is to use circular (i.e. FIFO) disk writes, causing the oldest buffer files to be overwritten as newer traffic is captured.

114ff specifications

Network Instruments 114ff is a sophisticated platform designed to enhance network visibility and performance management. This state-of-the-art device is aimed at network professionals who require a deep insight into their network’s behavior and performance metrics. One of its main features is its ability to provide real-time monitoring and analytics, which is crucial for quick decision-making in IT environments.

With a robust set of technologies embedded in its architecture, Network Instruments 114ff leverages advanced packet capture and analysis capabilities. It employs deep packet inspection (DPI) technology to evaluate data packets as they traverse the network. This functionality allows administrators to dissect various layers of network traffic, enabling them to identify anomalies and troubleshoot issues effectively. The 114ff can analyze both encrypted and unencrypted traffic, an asset as organizations increasingly adopt encryption protocols.

Another prominent feature of the Network Instruments 114ff is its customizable dashboard, which can be tailored to present the most relevant metrics at a glance. Users can visualize their network performance through a variety of graphs, charts, and alerts signaling potential performance degradation. This feature aids network managers in assessing key performance indicators (KPIs) and helps ensure that service level agreements (SLAs) are met.

The device is equipped with extensive reporting capabilities, allowing users to generate historical reports for analysis and compliance purposes. This function is essential for businesses that must comply with regulatory standards, as it enables them to maintain records of network performance and security incidents.

Furthermore, Network Instruments 114ff supports a variety of network protocols, ensuring compatibility with existing infrastructure. Its scalable architecture means organizations can adapt the device to cater to growing network demands without the need for significant overhauls. The integration capability with other Network Monitoring Systems (NMS) positions it as a flexible solution suited for diverse environments.

In summary, Network Instruments 114ff stands out as an essential tool for IT professionals looking to optimize network performance. With features such as real-time monitoring, deep packet inspection, customizable dashboards, and robust reporting capabilities, it delivers a comprehensive solution to manage and enhance network infrastructures effectively.
