The FADE (Filtering, Analysis and Data Export) tool allows for the freezing trace files of a particular time frame, selecting trace files, analyzing selected trace files and exporting selected Trace, Index, PCAP (Positioning Calculation Application Part) and QoS (Quality of Service) files via FTP or e-mail.
The FADE tool can be used by end users and administrators when attempting to locate and analyze trace data for a specific issue, problem or error condition. They will hopefully have specific info about the fault, such as time of occurrence, DNs (Directory Numbers) involved, errors observed, etc. which will be used as filtering criteria.
FADE provides a GUI interface to the following functionality:
- Data Filtering:
The subscriber may enter any combination of search criteria and the tool will search the stored index data to locate and identify the trace files associated with the requested data.
- Data Analysis:
The administrator may access basic analysis tools against the selected data. This may include opening the stored PCAP files with Ethereal (if installed) or initiating the SIP analysis of the raw trace data with the DAT tool (if installed).
- Data Exporting:
The administrator may request that the requested trace data be exported to development using e-mail or FTP. Scheduling may be setup to periodically export selected trace data automatically.
System Specific Information
The FADE tool can be instructed to transport selected trace files to another server most likely located at customer service and/or development site by e-mail or FTP/SFTP.
E-mail volume is limited to 4 MB.
FTP transfer rates are possible from 2 Mbit/sec to 400 Mbit/sec. No need for SFTP if using VPN tunnel to SIRA (Secure Infrastructure for Remote Access).
If QoS is wanted, the QoS "performance data" is embedded in the PCAP and the raw trace data files. There are no specific QoS files.
The analyzer tools are enhanced to select trace files using the list created by the trace filter for local analysis preferable via remote desktop.
Functions of the trace analyzer are:
Display summary line for each trace statement in human readable form with time stamp, DN and call ID.
Sort trace statements by DN, calI ID
Find call data of corresponding call legs
Show flag irregularities
Show message flows graphically
The analyzer tools are enhanced to display QoS data from the QoS database or the exported QoS file identified by call ID.
