  • DeveloperGuidelines/Testing/Load

    v1 v2  
    55
    66Testing should normally be done from a separate machine. [InstallationGuidelines/Amazon Amazon] is great as a platform for accessing a lof of resources for a short period of time.
     7 * A 'Micro' instance is sufficient for testing 100 concurrent users (the dynamic parts of the site)
     8 * A 'High CPU' instance is required for testing 6,500 concurrent users (the static parts of the site)
     9
     10== Server Setup ==
     11Tsung can include results on Server Load if SNMP is enabled:
     12{{{
     13apt-get install -y snmpd
     14vim /etc/snmp/snmpd.conf
     15#agentAddress  udp:127.0.0.1:161
     16agentAddress udp:161,udp6:[::1]:161
     17#rocommunity public  default    -V systemonly       
     18rocommunity public 0.0.0.0/0
     19
     20/etc/init.d/snmpd restart
     21}}}
     22
     23Notes:
     24 * Log files can fill-up quickly, especially when testing a large number of users for the static parts of the site
     25 * Database will need resetting to clear any transactions made
     26 * Reboot between tests to reset the RAM/Swap
     27
     28== Client Setup ==
     29
     30=== Installation ===
     31{{{
     32apt-get install -y erlang gnuplot libtemplate-perl make lrzsz vim
     33wget http://tsung.erlang-projects.org/dist/tsung-1.4.1.tar.gz
     34tar zxvf tsung-1.4.1.tar.gz
     35cd tsung-1.4.1
     36./configure
     37make
     38make install
     39ssh localhost
     40yes to accept hostkey
     41exit
     42}}}
     43
     44=== Static Tests ===
     45It is recommended to make the homepage of the site static. The performance of this page can be tested using {{{~/.tsung/tsung.xml}}}:
