Observer Q&A:
Example problems Expert Observer can help isolate:
What's causing the slowdown?
The Expert Analysis, real-time or upon completion of capture, will
provide a summary of conclusions about any problems and possible causes
in plain English.
Why has the company's main database become so slow?
Expert Observer will identify the client/server relationships automatically
and display expert analysis statistics, including slow response times,
busy network or server problems and retransmissions.
Will moving to Gigabit increase my network response time?
Expert Observer's What-If Analysis lets you create unlimited scenario
analysis based on your captured data. This allows you to accurately determine
the impact of changing variables such as network bandwidth, response time
and number of users and latency.
How can I isolate intermittent problems?
Expert Observer's Time Interval Analysis of data transmissions is
displayed as a "drill down" from any problem identified in the
IP/TCP/UDP, IPX/SPX, NetBios/NetBEUI, SQL, Oracle and 802.11 Experts.
Viewing errors by time periods will show whether a problem is sporadic
or consistent throughout the day.
Why can't I log in?
Packet Capture can display login negotiations, retransmissions and
response times to determine where the problem is.
Implementing VoIP, and need a tool to verify performance and check
compliance?
Expert Observer's complete decode of H.323, including VoIP, insures
you will have the tools you need when voice and data problems arise.
At what point will the added VoIP traffic critically impact the quality
of network communication?
VoIP Expert displays jitter and percentage of lost packets for each
VoIP pair, and both the amount of network utilization the conversation
is consuming and the total VoIP utilization on the network. With both
utilization and jitter data, problems can be easily pinpointed, and predictions
of future capacity can be made.
Can I get more detail about a particular conversation?
Expert Observer's connection Dynamics allows you to analyze and graphically
view any conversation's behavior displaying inter-packet timing between
stations (who is waiting on who) and conversational events, highlighting
retransmissions and lost packets in red.
