From Florent.Drouin@alcatel.fr:
Please find two new TAP for Camel Statistics.
The first one updates counters related to camel operations. It is located in the GSM submenu. The second one , named Camel Service Response Time, gives the time ellapsed between a couple of camel specifics operations. (For example InitialDP/Continue or InitialDP GPRS/Continue GPRS). With Wireshark, you can have the Min/Max/Mean delay time for your traces files, and with Tshark, you have the additional information for percentile (1%,95% 99% etc )
To enable the use of the Camel statistics, you have 2 new parameters in the preferences,
- SRT, enable the service Response Time calculation.
- persistentSRT, keep the data in a context, even after the camel session has been closed. This is mandatory with Wireshark, to have a clean display of the stats.
Only the new files checked in for now because of include problems.
