Isac is a Scenario Architecture for Clif
Presentation
ISAC is a Scenario Architecture for CLIF, which makes it possible to
define load scenarios for any kind of target system/protocols in a
graphical
manner. The main idea of ISAC is to have a formal representation of
user behaviors, combined with a load profile specifying the number of
emulated users acting according to such behaviors. An ISAC scenario
consist in composed of three sections:
- declaration of "plug-ins" providing the necessary
conditions, actions (or samples in ISAC terminology), timers and
session objects (keeping the emulated user state)
- definition of a set of sequential behaviors, with basic
constructs like loop, conditions (if-then-else), preemption, delays
(timers), and of course actions (samples)
- specification of a load profile for each behaviors
#emulated_user
(behaviori) = fi(time)
This editor can edit ISAC scenario in graphic mode or XML mode. Graphic
mode permit definition of plug-ins, behaviors and load profiles, while
XML mode permit
content assist edition and error detection.
It's also possible to make HTTP captures with integrated
MaxQ open source software. This feature will automatically generate
an ISAC scenario (see dedicated part in this help).
NB : In this help you will only find
a description of the graphic mode edition.
