Abstract
In the age of Information and
communication technology (ICT), web and internet
have brought significant changes in Information
technology. The dramatic change in website
development and their relative usage has led to the need
of web based metrics .These metrics will accurately
assess the efforts in the web based applications .So the
basic idea is to identify the web metrics for evaluating
reliability and maintainability of Hypermedia
applications where we characterize usage and problems
for web applications, evaluate their reliability and also
the potential aspects for reliability assessment and
improvement . Based on the characteristics of web
applications and the overall web environment, we
classify web problems and focus on the subset of source
content problems. Using information about web
accesses, we drive various measurements that can
characterize web site workload at different levels of
granularity .These workload measurements , together
with failure information extracted from recorded errors
are used to evaluate the operational reliability for
source events at a given website and the potential for
reliability improvement. As a result , to support this
strategy or methodology we extract web usage and
failure information from existing web logs. This failure
information is used to measure the reliability of web
applications. Hence these results obtained from the web
based metrics can help us analytically identically
identify the effort assessment and failure points in web
based systems and make evaluation of reliability of
these systems simple.
