21 Mar 2006 Examine how to determine the root cause of Web performance problems. Without proper measurement, how do you know whether your Web application is performing well? By using open source tools such as the RRDtool, you can graph the key performance measurements of any Web application, use these graphs to determine the impact of changes in the environment, or point to changes that need addressing.
In this tutorial
- Explaining Web performance
- RRDtool
- RRDtool graph
- Putting it all together
- Interpreting the results
Prerequisites
This tutorial is written for users who have a basic understanding of the UNIX® command line, some basic shell scripting knowledge, and a basic understanding of statistics (averages, minimum, maximum).
System requirements
To follow this tutorial, you need a computer running UNIX and a Web server. (The two can reside on the same computer.) In addition, you must have the following tools installed: Both of these programs follow the standard compilation and installation procedure:
- From the UNIX command line, run
tar -xzf filename.tar.gz.
- The last command creates a directory as part of the extraction process. Switch to this directory with
cd dirname
.
- Run
./configure to create the build instructions.
- Run the
make command to compile the source.
- Run the
make install command to install the software.
You might also find binaries for these programs provided by your vendor or third parties. You don't need to have the absolute latest versions of the software for this tutorial.
