A hybrid reliability model based on log analyzer is designed to evaluate the reliability of composite web services. Based on dependability, atomic web services are composed with a central co-ordination function (Broker). Real time server log files are fed as input to the system. Log analyzer reads the log entries and separates the individual response of the server along with the time stamps. Base on the frequency of the service response are classified and the error rate is calculated by the difference in the uptime and downtime stamps.
