Conversation Analytics

The Observer Expert network analyzer's TCP/UDP Expert Events alert you to issues such as excessive retransmissions, and provide an explanation of the problem and possible causes. Unique to Observer is Connection Dynamics, which breaks out individual network conversations graphically, piece-by-piece, so you can see exactly where the problem is occurring.

Retransmissions and dropped packets are flagged in red, so you'll know at a glance where problems lie. Likewise, large spaces between conversation sections are a simple way to spot latency and response time issues.

Observer Expert allows you to literally keep an eye on network conversations and latency issues with its Connection Dynamics view.

Unified Communications

Unified communications shifts an entirely new burden onto the network. The Observer Expert network analyzer helps ensure quality voice, video, telepresence, and data interactions.

Whether it is making certain your network can handle your next international videoconference, keeping the sales department's instant messaging up and running, or providing VoIP call center customers with the best possible experience, Observer Expert has valuable tools for planning, implementation, and maintenance.

Observer Expert lets you monitor Quality of Service (QoS) levels and quality scores, save and replay voice and video, view actionable call detail, gain high-level traffic summaries, and more.

Set custom alarms for instant notification and react quickly with help from Expert Analysis. Utilize tools such as Trace File Aggregation to monitor and troubleshoot a single voice conversation traveling across multiple links.
