Monitoring and Managing Network Application Performance |
Stop Failures, Improve Performance |
Network managers and engineers are switching their focus from network performance issues to application problems. Whether it’s custom applications, VoIP traffic, or HTTP, Network Instruments provides comprehensive application analysis, allowing for rapid problem resolution and long-term planning.
Observer is the only monitoring solution to fully integrate application performance management into its entire line of monitoring solutions.
Network Instruments Application Analysis allows you to:
Understand application performance enterprise-wide or focus on specific locations with the Observer Reporting Server. Our solutions also provide historical views to measure response time degradation and better plan for future updates.
Observer's Application Analysis makes it easy to pinpoint transaction problems. Observer provides unique views of system conversations for instant identification of abnormal response times. For example, retransmissions and lost packets are flagged for quick identification.
Find problems caused by network congestion, fragmentation, and packet loss by isolating transaction problems, delay, and intermittent connectivity.
Observer’s application performance tools provide insight into complex applications which may involve routers, switches, load balancers, and multiple servers. Its MultiHop Analysis tool answers the critical question, “Is it the access layer, the core, or my service provider?” by starting and automatically synchronizing simultaneous packet captures from different network segments.
Application Transaction Analysis goes beyond tracking response times to provide detailed application-specific performance metrics.
Highlighting any pair will display Expert Analysis in the "Expert Analysis" pane at the bottom of the display. Expert Analysis is offered for client, network and server.
Problem Status indicators:
Station pairs are evaluated and the server designated if it can be identified.
response time, network delay are calculated from the monitoring probe.
Retransmisions are quantified as well as noting other expert conditions.
TCP/UDP/ICMP, VoIP, Wireless, IPX/SPX, and NetBIOS/NetBEUI
There is
Event analysis for all major protocols. Each 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.
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.
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.
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.
Become Your Network’s Forensic Expert with Stream Reconstruction
When troubleshooting application problems, it is often important to know what file was accessed, what spreadsheet sent, or what webpage viewed.
Observer’s Stream Reconstruction allows you to do exactly that, by capturing and recreating web pages, e-mails, and more, exactly as they were viewed.
Use Observer to recreate:
Observer monitors point-to-point connections using the End-to-End Analysis feature. With it you can determine the exact time conversations between two network points occurred. Observer provides in-depth conversation information the exact network delay between the two points.
Measuring and monitoring application response time is critical in today’s on-demand environment. Fortunately, Observer provides response time data for thousands of standard and user-defined applications.
Server latency, transaction issues, network delay—all of this impacts application availability. Observer provides detailed metrics that allow you to pinpoint the exact cause of bottlenecks or slowdowns—ensuring a faster time to resolution.
The Application Transaction Analysis window shows you the following about your applications and servers:

Aggregate Application Reporting for the Enterprise
Observer provides large-scale, network-wide reporting with the unique ability to drill down from the report to begin immediate problem resolution. Use this data to gauge long-term application use, monitor trends, and segment application health by location or department.
Provides transaction volume, a Visual display of performance rankings that are met or exceeded listed by the Aggregated applications.
Now with ORS NetLive receive real-time application health on a global scale. NetLive provides 20-second resolution on top applications, response times, and other critical network and application metrics. Organize reports by business group and allow anyone in your organization access via a web secure login. More on Observer Report Server (ORS)
Manage Application Rollouts
Measure twice, cut once. Too often organizations roll out applications without adequate testing. With Observer it is simple to test and review application impact before deployment.
Observer offers on-board tools to conduct network assessments, identify potential deployment obstacles, and make configuration adjustments. Use Observer’s predictive expert to forecast the impact of new applications on current bandwidth conditions.
