1 Monitoring Applications on Pramati Server 28 Overview The Console monitors all the *.ear, *.war, and *.jar applications that have been deployed on it. To do so, select Monitor > (type of) Application you wish to monitor. All the application statistics can also be accessed using the Home page > Applications section. Note: For being able to monitor an application, make sure that you have deployed it on the Pramati Server first, and completed all the required mappings etc. Monitoring Enterprise Applications To monitor a *.ear application on the Console, select Monitor > Enterprise Applications under the section titled Applications. The following details are displayed for the deployed applications: Table 1: Monitoring a deployed Enterprise Application Name Name Context Root Start Time Sessions Hits Transactions Statistics Description Refers to the name of the deployed application Refers to the context root of the deployed application Displays the Date and time the application was deployed Refers to the number of sessions running in the application Refers to the number of times the application was accessed Refers to the number of times the application was accessed Displays the statistics for the deployed application, when clicked
