Hi Sudharshan,
The SOAP service mentioned by Hareesh, is used to consume already generated alerts. As indicated by him, once consumed using that SOAP service, the alert will not be available anymore (it will be deleted from the alert queue).
If you need to browse alerts, and not consume them, you may want to look into respective JMS queues, which are registered in JMS Provider of AS Java of PO, and are filled with messages corresponding to produced alerts.
JMS queue name is: jmsqueues/alertingVP/jms/queue/xi/monitoring/alert/<alert consumer>, for example, jmsqueues/alertingVP/jms/queue/xi/monitoring/alert/ALERT-TO-MAIL for the mail consumer ALERT-TO-MAIL.
Please also have a look at Tihomir Stoyanov's blog PI Alerting on AAE/AEX to get some more details on this topic.
Following this approach, you can browse (not consume) alerts for specific alert consumers. Please note that if there are several consumers for the produced alert, you will find the same alert produced, replicated and persisted in several corresponding JMS queues. If there are no consumers for the alert rule, runtime will not produce any alerts and you will see no JMS entries there.

Vadim
