Key Features

Application PerformanceApplication Performance

Reduce downtime and increase productivity with in-depth, contextual application analysis. Get response time data for thousands of applications plus performance metrics, transaction detail, and predictive analytics that show the network impact of new application deployments.

Expert AnalysisExpert Analysis

Get immediate intelligence in both real time and post capture using Expert Events for TCP, UDP, VoIP, Wireless, and more. It tracks and organizes common services, flags response performance by severity, tracks port-based protocols for slow response, and differentiates between network and application problems with local traffic and WAN/Internet traffic distinction. Enhanced HTTP application monitoring offers deep insight into how web-based applications are operating, as well as how users are accessing IT resources, including browser type and operating system.

Conversation AnalyticsConversation Analytics

The only network analyzer that offers Connection Dynamics, it graphically breaks down individual network conversations piece-by-piece, pinpointing which request or response is causing the issue. Retransmissions and dropped packets are flagged for instant recognition of the issue source. Spaces between conversation sections identify latency and response time issues. TCP/UDP Expert Events show excessive retransmissions, and provide an explanation of the problem and possible causes.


Use network trending to forecast IT needs or justify upgrades with comparative reports. View and analyze network traffic stats over periods of time — from days to years. Trending metrics can be broadly applied to meet diverse challenges like translating web traffic into Internet usage data to appropriately bill departments on service use.


Perform in-depth troubleshooting with an interface that provides intuitive workflows for quick problem resolution. Deep drill-down capabilities with root-cause analysis pinpoint issues at the source with accuracy and ease. High-performance packet capture, decode, and filtering capabilities offer additional support.

Triggers & AlarmsTriggers & Alarms

Analyzer deploys ongoing monitoring of activity levels and immediately sends prioritized alerts when network fluctuations cross your pre-set levels. It gives you the following alert options: emails, paging, trouble tickets, or kick starting an automated packet capture.

Features also include flagging activities or errors from a pre-defined list; setting custom notifications based on any filter; obtaining email with virus information (including source and destination); and placing triggers on any WLAN activity.

Packet CapturePacket Capture

Analyzer's packet capture, decode, and filtering capabilities are second to none. It lets you view individual packets and decode for over 740 primary protocols and countless sub-protocols. Observer filters packets quickly and efficiently by address, address range, protocol offsets, and protocol presets using the intuitive GUI and by-command line.
