2.autobench

The httperf is encapsulated to not only test the results of one condition, but can continuously increase the amount of test to test the bottleneck of performance.
: http://www.xenoclast.org/autobench/

The default configuration file is as follows:
More autobench.conf

Note : Be sure to copy the configuration file to the user's home directory, so program execution needs to read this file; after installation, the default is/usr/local/etc/autobench.conf

  
 

   
  

  
# Autobench Configuration File
   
  

  

   
  

  
# host1, host2 
   
  

  
# The hostnames of the servers under test
   
  

  
# Eg. host1 = iis.test.com 
   
  

  
# host2 = apache.test.com
   
  

  

   
  

  
host1 = testhost1 
   
  

  
host2 = testhost2
   
  

  

   
  

  
# uri1, uri2
   
  

  
# The URI to test (relative to the document root). For a fair comparison
   
  

  
# the files should be identical (although the paths to them may differ on the 
   
  

  
# different hosts)
   
  

  

   
  

  
uri1 = /
   
  

  
uri2 = /
   
  

  

   
  

  
# port1, port2
   
  

  
# The port number on which the servers are listening
   
  

  

   
  

  
port1 = 80
   
  

  
port2 = 80
   
  

  

   
  

  
# low_rate, high_rate, rate_step
   
  

  
# The ‘rate‘ is the number of number of connections to open per second.
   
  

  
# A series of tests will be conducted, starting at low rate,
   
  

  
# increasing by rate step, and finishing at high_rate.
   
  

  
# The default settings test at rates of 20,30,40,50...180,190,200
   
  

  

   
  

  
low_rate = 20
   
  

  
high_rate = 200
   
  

  
rate_step = 10
   
  

  

   
  

  
# num_conn, num_call
   
  

  
# num_conn is the total number of connections to make during a test
   
  

  
# num_call is the number of requests per connection
   
  

  
# The product of num_call and rate is the the approximate number of
   
  

  
# requests per second that will be attempted.
   
  

  

   
  

  
num_conn = 5000
   
  

  
num_call = 10
   
  

  

   
  

  
# timeout sets the maximimum time (in seconds) that httperf will wait
   
  

  
# for replies from the web server. If the timeout is exceeded, the
   
  

  
# reply concerned is counted as an error.
   
  

  

   
  

  
timeout = 5
   
  

  

   
  

  
# output_fmt
   
  

  
# sets the output type - may be either "csv", or "tsv";
   
  

  

   
  

  
output_fmt = tsv
   
  

  

   
  

  
## Config for distributed autobench (autobench_admin)
   
  

  
# clients 
   
  

  
# comma separated list of the hostnames and portnumbers for the
   
  

  
# autobench clients. No whitespace can appear before or after the commas.
   
  

  
# clients = bench1.foo.com:4600,bench2.foo.com:4600,bench3.foo.com:4600
   
  

  

   
  

  
clients = localhost:4600
  
 

Execute Test Command
./autobench–single_host–host1 192.168.210.155–port1 10002–uri1/index.html–quiet–low_rate 20–high_rate 200–rate_st EP 20–num_call 10–num_conn 5000–timeout 5–file RESULTS.TSV

Httperf:warning:open file limit > fd_setsize; limiting Max. # of open files to Fd_setsize

If you do not add parameters, the parameters in the configuration file are used by default

The final result is a TSV-formatted file, which can be drawn using the tool that comes with the 1.10 release, drawing results from gnuplot

Bench2graph takes a TSV format autobench results file, and uses gnuplot to graph the results, producing output in POSTSCRI Pt.
Note the resulting picture format is PostScript

./bench2graph RESULTS-1.TSV Results-1.ps

using Ghostview to open a picture is recommended under Windows
