Curlloader queries

[Sridhar G. <sri...@re...>]

Hi All,

When i was doing some research on open source projects that could replace Ixload to generate and simulate HTTP traffic on the client machine to connect to Apache webserver and report the results

I found curl-loader an interesting tool to start and explore to replicate my test scenario what i was trying to do on Ixiaload. Im interested in using this tool so I played around config file to generate Http traffic to test number of connections to fetch couple of urls from Webserver which resulted me in posing few questions in mind towards its operation with my conf file below:

########### GENERAL SECTION ################################

BATCH_NAME= http

CLIENTS_NUM_MAX=1000 # Same as CLIENTS_NUM

#CLIENTS_NUM_START=1

#CLIENTS_RAMPUP_INC=1

INTERFACE=eth2a

NETMASK=24

IP_ADDR_MIN= 10.10.1.101

IP_ADDR_MAX= 10.10.1.101 #Actually - this is for self-control

CYCLES_NUM=1

URLS_NUM=1

########### URL SECTION ####################################

URL=http://192.168.10.x/4k.html

#URL=http://192.168.10.y/index1.html

#URL=https://localhost/apache2-default/ACE-INSTALL.html

#URL=https://localhost/ACE-INSTALL.html

URL_SHORT_NAME="url-http"

REQUEST_TYPE=GET

TIMER_URL_COMPLETION =0 # In msec. When positive, Now it is enforced by cancelli

ng url fetch on timeout

1. Can I make 1000 connections/sec with one client ?

So am I following the right way inorder to achieve what im trying to accomplish as defined with question 1.

2. what are the factors or criteria that lets curl-loader knows when to stop the test.?

The reason I asked above question is trying to uderstand whether curl-loader could successfully establish 1000 connections in a second if not how to varies it connection rate?

What is the role of interval option -i in determining the connection rate.

3. when i look at the results what does Success really indicates from left and right column?

For example, what does 151 1000 means under the Sucess column in results file.

 

I appreciate answers for the above questions that will help me in making progress towards using this tool and making enhancements that fits to my test requirements. Please let me know if any additional details are required that would help me in assisting.

 

Thanks

Sridhar
