The CSA Expert Alert function automatically detects communication faults from captured or monitored packets and displays them with color coded icons. The specific application, server, or flow that has a problem can be seen at a glance from the Application Summary Front Page.

Alerts detected by CSA, either in real–time or from a trace file, are classified as issues (faults in the communication sequence) or problems (faults that exceed a threshold value) and are logged. Lists can be sorted by simply clicking on a column header. You can drill down to the associated flow causing the problem by right–clicking on an alert during post–capture analysis. Problems and issues can trigger email, pager, script, or SNMP trap actions.

Analyzing large capture files can be difficult because there is just too much information to sort through. CSA provides a time-based analysis of capture files providing detailed statistics and trending information. You can drill down in time to look at adjacent events during the time of interest. For video and voice traffic running SIP or H.323, the analysis engine can classify the video and voice RTP streams based on their quality score, MOS or VQFactor. It will provide detailed statistics of the SIP or H.323 call status and quality of calls.
You can select one or more of the RTP streams to be extracted for detailed analysis or replay. Additional analysis is available for HTTP, listing tables clients by server or vice–versa along with specifc URLs accessed and error codes. With this analysis, users can identify the problems quickly, without drilling into packet decodes.
