Expert Observer Benefits:

 

Expert Observer includes all the benefits of base Observer plus additional key features for identifying network issues and offering immediate solutions.

Observer goes beyond traditional Expert Explanations - It has very detailed analysis for Application Performance, Wireless and VoIP.

Expert Summary Problem Analysis

Shows error events in a single, concise display. For connection-orientated problems, a simple double-click drills down for further analysis. Expert problem identification is displayed for TCP/UDP/ICMP, Wireless, IPX/SPX, NetBIOS/NetBEUI, SQL and Frame Relay.

 


TCP/UDP/ICMP, Wireless, IPX/SPX, and NetBIOS/NetBEUI Expert Event Identification

Shows protocol-based and application-based problems in real-time. Local traffic is judged using different criteria than WAN/Internet traffic to help make certain no false readings are provided. All port-based services are tracked, slow response/no response and slow connect/no connect are flagged and sorted by severity. A generic TCP conditions expert tracks all port-based protocols for slow response or connection characteristics.

Connection Dynamics

Provides a graphical view of system conversations. Packet-to-packet delay times are shown visually, allowing instant identification of long latency and response times. Retransmissions and lost packets are flagged in red for quick identification. Should a particular packet require further investigation, its decode is only a click away.

Time Interval Analysis

Any conversation can be displayed as a “drill-down” from any problem identified in the IP/TCP/UDP Experts. Time Interval Analysis shows network errors organized by time periods to identify whether a problem is sporadic or consistent throughout the day. This information is critical in determining if a problem is spread throughout a period of hours, or if it localized to a specific time span. Network utilization within the Interval Analysis is displayed to help match slow responses with heavy network load.

Server Analysis

Displays a server's response times charted against the number of simultaneous requests asked of that server. Response times are charted for recorded request sets, and plotted for predicted response times as request loads increase.

 

“What If” Modeling

Starts with measurements based on actual client/server conversations, or peer-to-peer conversations and plots possible response time, utilization and packet flow scenarios. This allows you to predict network bandwidth and response-time impact for topology changes (e.g. 10MB to 100MB) or by changes in variables such as average packet size, send-to-receive packet ratio, latency, server load, number of users. This “live-modeling” lets you assess the impact of possible network or application changes.

MultiHop Analysis

MultiHop Analysis and capture feature offers time synchronization technology that can track conversations through multiple segments, hops, and routes and identify the delays between hops. Require a probe at each hop to capture all points of a conversation. This feature quantifies transaction time between PC and server using a Network Instruments exclusive method of synchronizing captures. Pinpoint bottlenecks within specific conversations or verify if 3rd party service providers are performing to their SLA. Helps isolate if slowdowns are due to network delay or system processes.
