Hello,
I'm running sipp v3.4.0-RTPSTREAM.
I found that I am not able to start a registration script when the
registration rate is greater than 1000 reg/sec. I'm using options -r
1047 -rp 1000.
If the registration rate is less than or equal 1000, the script works
fine. Otherwise, it starts but does not generate any load.
Here is a screenshot for a working case:
------------------------------ Scenario Screen -------- [1-9]: Change
Screen --
Call-rate(length) Port Total-time Total-calls Remote-host
1000.0(0 ms)/1.000s 5500 6.00 s 5982 135.1.216.65:5060(UDP)
998 new calls during 1.001 s period 0 ms scheduler resolution
0 calls (limit 3000) Peak was 5 calls, after 0 s
0 Running, 5983 Paused, 473 Woken up
0 dead call msg (discarded) 0 out-of-call msg (discarded)
3 open sockets
Messages Retrans Timeout Unexpected-Msg
REGISTER ----------> 5982 0 0
200 <---------- E-RTD1 5982 0 0 0
------ [+|-|*|/]: Adjust rate ---- [q]: Soft exit ---- [p]: Pause
traffic -----
And here is a screenshot for a non-working case:
------------------------------ Scenario Screen -------- [1-9]: Change
Screen --
Call-rate(length) Port Total-time Total-calls Remote-host
1047.0(0 ms)/1.000s 5500 2.00 s 0 135.1.216.65:5060(UDP)
0 new calls during 1.002 s period 1 ms scheduler resolution
0 calls (limit 3141) Peak was 0 calls, after 0 s
0 Running, 2 Paused, 3 Woken up
0 dead call msg (discarded) 0 out-of-call msg (discarded)
3 open sockets
Messages Retrans Timeout Unexpected-Msg
REGISTER ----------> 0 0 0
200 <---------- E-RTD1 0 0 0 0
------ [+|-|*|/]: Adjust rate ---- [q]: Soft exit ---- [p]: Pause
traffic -----
Note that if I start the script with less than 1000 reg/sec and then I
increase them manually, everything works just fine.
Here is a screen shot showing that:
------------------------------ Scenario Screen -------- [1-9]: Change
Screen --
Call-rate(length) Port Total-time Total-calls Remote-host
1030.0(0 ms)/1.000s 5500 10.01 s 10208 135.1.216.65:5060(UDP)
1033 new calls during 1.002 s period 0 ms scheduler resolution
0 calls (limit 3090) Peak was 5 calls, after 2 s
0 Running, 10209 Paused, 481 Woken up
0 dead call msg (discarded) 0 out-of-call msg (discarded)
3 open sockets
Messages Retrans Timeout Unexpected-Msg
REGISTER ----------> 10208 0 0
200 <---------- E-RTD1 10208 0 0 0
------ [+|-|*|/]: Adjust rate ---- [q]: Soft exit ---- [p]: Pause
traffic -----
So, it seems that sipp is capable of handling a rate greater than 1000,
but not if starting the script with that value.
I need to start several scripts like this from a shell script, for lab
automation registration and call load testing. Is there a way to
overcome this limitation?
Thanks in advance for any help you can give,
Carlo
