etc., by clicking on the appropriate tab and selecting the items you want to see on the time line chart.

Display Controls

Charts and statistical tables are refreshed only when you click the Update Chart or Update Statistics button. The buttons will flash with a red border when a refresh is necessary. You can also have the display auto-update. For details, “GigaStor Options tab” on page 64.

You can change the Screen resolution (in other words, the time scale) and which Data type (i.e., packets or bytes, either per second or totals) to chart by using the drop-down controls and per second check box. The Statistics interval control lets you display network statistics based on the entire visible chart, or only show data derived from the time interval you have selected to analyze.

The FIFO gauge on the right side of the control pane tracks how well GigaStor’s disk hardware is keeping up with the current traffic load; if the FIFO gauge shows 90% or greater, you should consider reducing the load using one or more of the following methods:

Allocate more memory to the GigaStor instance. See the instructions in “Probe administration” on page 24 for details about allocating memory for the probe instance.

Activate dynamic sampling, or increase the fixed sampling ratio. See details about packet capture in “Packet capture buffer and statistics buffer” on page 54.

Activate partial packet capture or reduce the size of portion captured. See details about partial packet capture in “Capture partial packets” on page 65.

The Rate: field shows how much traffic the GigaStor will be able to archive given the active instance’s current disk usage rate. It is updated dynamically as the usage rates change. To increase the archivable time window, activate partial packet capture and sampling as described above, or apply pre-filtering.

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.
