The Service Monitoring Agent is designed to manage applications such as database, web server, mail server etc. Agents manages applications through a number of entry points including "online", "offline" and "monitor". The "online" entry point will start the application. The "offline" entry point will stop the applications. Other entry points such as "init", "clean" and "shutdown" will also be performed depending on the applications managed. The Agent integrate seamlessly with SIC or offer much flexibility in monitoring the managed applications. An agent can communicate in SMTP with a mail server and query a database server using SQL. SMAs allow precise efficient application availability control and monitor with vendor level certification. The use of SMA can maximize the availability of the target application and thus miminize unplanned downtime.
