Keyword Definition Keyword is a set of attributes, which signifies the behavior of NetStorm or Test Scenario. Syntax and semantics of value(s) depend upon the keyword. Default values of the keywords are used when a keyword is missing from configuration file. Most keywords have default values

Keyword Format <Keyword> <value1> <value2> …. <valueN> For examples: G_PAGE_THINK_TIME Static1kGrp ALL 0 G_SESSION_PACING Static1kGrp 2 0 1000

How Keyword Value are taken from different files? Setting for scenario are taken from the following files in this priority: Scenario file All keyword values are first taken from this file sys/site_keywords.default All keywords values in this file which are NOT present in the scenario file are taken from this file include/VendorData.default All keywords from this file which are NOT present in above files are taken from this file etc/KeywordDefinition.dat All keywords from this file which are NOT present in above files are taken from this file. These are default values.

Example: >> Scenario will have G_IDLE_MSECS 120000 Scenario file No G_ IDLE_MSECS sys/site_keywords.default G_IDLE_MSECS ALL 12000 include/VendorData.default etc/KeywordDefinition.dat G_IDLE_MSECS default value is 60000 >> Scenario will have G_IDLE_MSECS 120000

How to verify what value is taken?: TRXXXX Sorted_username_scenarioname.conf Grep G_IDLE_MSECS sorted* >> Scenario will have G_IDLE_MSECS ALL 120000

Keyword Types Keywords are on following types: Schedule Setting Global Setting Group Based Settings Server Mapping User Profile

Schedule Settings – Add Groups Make sure Schedule Type is ‘Simple’ and Schedule By ‘Group’ Add groups by clicking on add button as per the requirement

Schedule Settings Start Phase Use to give some delay before starting virtual user generations. Useful if you want to collect monitor data before actual load starts Options: Immediate – No delay (Default) Time mode – Specified delay Start when Group finishes After Group + Delay

Scenario requirements - Groups Scenario Type: FCU scenario Keyword Used <STYPE FIX_CONCURRENT_USER> Scenario Groups Total Users - 300 Number Mode Two groups with Number as shown G1 for Script HPDTours –100 G2 for Script static1K –200

Scenario requirements - Schedule Schedule consists of following phases for group G1: Start phase – IMMEDIATELY Ramp Up – 10 Min LINEARLY Stabilization – 0 seconds Duration – 5 Minutes Ramp Down – 1 Minutes

Scenario requirements - Schedule Schedule consists of following phases for group G2: Start phase – 1 Min Ramp Up – 5 Min LINEARLY Stabilization – 0 seconds Duration – 10Minutes Ramp Down – 2 Minutes

Expected Result Start phase G1 will start immediate G2 will start after 1 minute

RampUp Phase Group Name Ramped Up users After 1 min Ramped Up After 6 min Ramped Up After10 min G1 10 10+50 10+50+40 G2 200

Total Connections After 1 min total users are in the system are 10 from G1 we are using hpd_tours script in group G1 then only 40 connections will be after 1 min. After 6 min total users are in the system are 260 From group G1 -60 users, then total connections are 240 due to hpd_tours. From group G2-200 users, then total connections are 200 due to Static1K. Then total connections after 6 minutes are 440. After 10 minute total users are in the system are 300 users From group G1-100 users, then total connections are 400 due to hpd_tours. Total connections after 10 minutes are 600.

Stabilization Phase Stabilize 0 second for both the groups.

Duration Phase G1 will run for 5 minutes G2 will run for 10 minutes In Duration phase no. of connections of both group remain fixed until duration time for both group i.e.600 connections After completing 5 minute, G1 will start RampDown, so established connection going to be decrease and after 10 minute of duration all established connection should be closed.

RampDown Phase G1 will be ramped down in 1 minute.

Total time taken in the execution of the scenario. Group Name Start phase(in min) Ramp Up(in min) Stabilize Duration(in minute) Ramp Down(in minute) Total time(in minute) G1 10 5 1 16 G2 2 18 Total time taken in scenario execution = 18 minutes(expected)
