Hi all,

I have successfully installed Erlang(otp_src_18.1) and Tsung(tsung-1.6.0).on Linux(Centos)
Creating a XML basic.file:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE tsung SYSTEM "/usr/local/share/tsung/tsung-1.0.dtd" []>
<tsung loglevel="warning">
<clients>
    <client host="localhost" cpu="2" maxusers="800"/>
  </clients>
  <servers>
    <server host="tuoitrenews.vn" port="80" type="tcp"></server>
  </servers>
  <load>
    <arrivalphase phase="1" duration="1" unit="minute">
      <users arrivalrate="5" unit="second"/>
    </arrivalphase>
  </load>
  <sessions>
    <session name="http://tuoitrenews.vn/" probability="100" weight="1" type="ts_http">
      <request><http url="/charity" method="GET"></http></request>
    </session>
  </sessions>
</tsung>

Running the tsung is: tsung -f basic.xml start

Tsung finish running, I genearate a report using:
/usr/local/lib/tsung/bin/tsung_stats.pl --stats /root/.tsung/log/20151118-1510/tsung.log

It show error:
