💖 NAME 💖

tsung — a distributed multi-protocol load testing tool. bestie. she stresses servers so you don't have to 🫶

✨ SYNOPSIS ✨

tsung [ -f configuration file ]  [ -l log dir ]  [ -m filename ]  [ -r
command ]  [ -X directory ]  [ -w delay ]  [ -L lifetime ]  [ -s ]  [ -n
]  [ -k ]  [ -v ]  [ -6 ]  [ -h ]  [ start|stop|debug|status ]

🌸 DESCRIPTION 🌸

okay so. tsung is a distributed load testing tool — like, it throws a whole party of fake users at your servers to see if they survive 💅. It's protocol-independent, and right now it can stress and benchmark HTTP, WebDAV, LDAP, PostgreSQL, MySQL and Jabber/XMPP servers. no cap.

It simulates user behaviour using an XML description file, and it reports, like, so many measurements in real time (statistics can be customized with transactions, and the graphics get generated using gnuplot). literally main character energy.

For HTTP, she supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET and POST methods, Cookies, and Basic WWW-authentication. She also has support for SSL. obsessed.

Several config examples can be found in /usr/share/doc/tsung/examples/. 🎀

• start — start tsung load testing
• debug — start tsung with an interactive erlang shell
• stop — stop tsung
• status — print current status of a running instance of tsung (must be run on the controller host)
