[Tsung] Recording session using proxy's problem

[Dmitry Mikheev]

Hi there,

I'm experiencing problems with tsung recorder, i can't browse through it's
proxy.
My goal is to test proxy performance, so i use      <option type="ts_http"
name="http_use_server_as_proxy" value="true"></option>

loadgen (tsung), internal cache (squid) and external proxy to internet, and
i'm trying to generate a network load on internal cache using tsung.
I use firefox on loadgen to record a sessions for tsung.

If i connect using internal cache, i can see external internet resources
trough external proxy.
If i connect using tsung recorder, i can't see anything, i can't see any
traffic to external proxy with tcpdump from recorder.

The problem is, recorder tryes to resolve addresses itself, instead of
putting this task on internal cache, am i right?
Is there a way to setup recoder to use parent proxy completely? Is there a
workaround?

tsung version 1.2.1

my tsung.xml:
<?xml version="1.0"?>
<!DOCTYPE tsung SYSTEM "/usr/share/tsung/tsung-1.0.dtd">
<tsung loglevel="notice" version="1.0">

<!-- Server side setup -->

</servers>

<!-- to start os monitoring (cpu, network, memory). Use an erlang
agent on the remote machine or SNMP. erlang is the default --> <monitoring>
 <monitor host="192.168.232.128" type="snmp"></monitor>
</monitoring>

<load>
<!-- several arrival phases can be set: for each phase, you can set

<arrivalphase phase="1" duration="10" unit="minute">
  <users interarrival="2" unit="second"></users>
</arrivalphase>
</load>

<options>
  <option type="ts_http" name="http_use_server_as_proxy"
value="true"></option>
<option type="ts_http" name="user_agent">
 <user_agent probability="80">Mozilla/5.0 (X11; U; Linux i686; en-US; rv:
