Thanks Ellie! The information is very helpful ;)
I have identified at least, in stack.cpp as well as in
stateful_proxy.cpp, both files have the data structure, pjsip_rx_data*
rdata, which contains the SIP messages sprout receives.
Next I'm about to decide where to implement the feature of recording the
start/completion timestamp of a call session and the RTP endpoints of
both sides.
In the meantime, I also want to know if there exists a script that can
do stress testing, i.e., establishing a few hundred simultaneous SIP
requests to the bono proxy.
I understand that the existing test suite, clearwater-live-test,
provides an option of repeating the call operation for a specified
number of times. But these SIP requests are sent sequentially. Please
advise a way of stress testing. Thanks!

Lilin

Hi Lilin,
You can find the details for building/installing each clearwater component in
the docs section of the repos - e.g. for sprout/bono this is
https://github.com/Metaswitch/sprout/blob/dev/docs/Development.md.
The stable branch in each repo marks the latest release (currently Final
Fantasy), I recommend this branch unless you need the very latest code (which
is in the master branch).
The 'stateful_proxy' module registers for receiving requests and responses; it
is responsible for handling requests and setting up the necessary transactions.
A description of the different modules, their functions and their structure is
at:
https://github.com/Metaswitch/sprout/blob/dev/docs/Bono%20Sprout%20Architecture.md
Hope this helps!
Ellie

Thanks Ellie,
I plan to modify the source code to implement this feature (automated script
that records the start and completion time-stamp of a call session, as well as
the RTP endpoints of both sides.)
If you could provide the information on the following, I'd be very
appreciated:
(1) Would you please provide me the instructions of installing clearwater ims
from source code, and/or the instructions of re-compiling clearwater ims?
(2) I need to know which branch is stable that I shall use (master, dev,
stable, rtr_cache, etc?)
(3) Which cpp file/functioin in sprout that handles the incoming call session (
it would save me some time, if you could point it out ) Thanks!
Regards,
Lilin

Hi Lilin,
We don't have a tool as you describe.
Have you looked at our call latency stats though - this will give you average
call latency over a 5 second period. Details of our stats are at
https://github.com/Metaswitch/clearwater-docs/wiki/Clearwater-SNMP-Statistics,
and there are some scripts at
https://github.com/Metaswitch/cpp-common/blob/master/scripts/stats.
If you need more fine grained results, then our logging code is in
https://github.com/Metaswitch/cpp-common/blob/master/src/logger.cpp. This
calculates the current timestamp every time it makes a log. If you do add this,
please do consider contributing this back to Clearwater!

Hello,
I see that clearwater-live-test suite provides only binary outputs,
such like PASS or FAIL for each scenario (Basic Registration, Basic
Call, and
etc.) But I want to see a way so that the performance can be measured
numerically, and done for each two-party call session (i.e., the
measurement needs to be taken at the IMS server side, not merely at
the testnode side.)
I'm writing to see if there is already an automated testing script that records
the start and completion time-stamp of a call session, as well as the RTP
endpoints of both sides.
I see that these time-related information (time-stamp for the sip messages -
INVITE, 200 OK, BYE) and RTP endpoints already exist in sprout's log file.
Hence there must be a function does this log-writing job. Which function is it?
I'm thinking about to modify this function such that each time when it
is about to write a log line (for the particular SIP messages -
INVITE,
200 OK, BYE), the function will also invoke a separate script (my
implementation) and record the time-stamps and RTP endpoints to another
numerical measurement result file. Please let me know you opinion about this
modification. Thanks!
Regards,
Lilin
