The response time of a web application is one of the most important factors to create a convenient user experience. Nobody spends much time exploring a site with a sluggish response time. So you need to understand where the time is spent to improve the response time of your web application. This article is about the response time log of the Apache HTTP Server. It seems to be mostly unknown that the Apache HTTP Server can write the response time for each request into a logfile. All you need is a custom log with the specific log directive. In this article, we shall look at some of the best IDEs or code editors you can find on the Linux platform for CC or any other programming. This article aims at building your personalprivate cloud storage using ownCloud 9 application. Zabbix is an enterprise open source monitoring software for networks and applications, created by Alexei Vladishev. It is designed to monitor and track the status of. Panasonic CFS9ZABBIX3.

Since Apache is capable of writing to multiple log files, there is no need to change the format of the common log. You can simply create an additional log for the response time analysis and continue to use the common log for other web analytics software. I am using the following configuration to generate a logfile with some useful details to investigate the response times of my web server Define logfile format used for response time analysis.

The final item of every log entry is the interesting part. This is the response time in microseconds 1 second 1. The time not only contains CPU time spent by different software components webserver, server side scripting languages, databases,. IO waits, database lock waits, network latencies in n tier environments, A couple of things I would like to mention though The time is measured on the webserver and reflects the time spent to generate a single response. The server obviously doesnt know about dependencies between content items. The time needed on the client to fetch everything and render the page is definitely higher. Large documents like digital images or videos probably show large response times when the client uses an internet connection with a low bandwidth. This is caused by the way TCPIP uses output buffers to keep data until it has been acknowledged. The throughput of the connection depends on the slowest link and the sender has to wait until it knows that everything arrived at the receiver. At first this approach may look more clumsy than the typical web analytics software Analog, AWStats, Piwik, Webalizer, But in my opinion the real power is revealed when this data is used to perform statistical analysis.
