Creating and Managing Alerts Alerts are generated for network events, and they may be triggered by the simple occurrence of an event or by the crossing of a threshold value for a monitored Interface, Volume, or Node. Alerts can be set to notify different people on different days, different times of the day, different people for different events, or any combination of times, events, and people. Alerts may be configured to notify the people who need to know about the emergent event by several mediums, including: • Sending an e-mail or page • Playing a sound on the Orion Network Performance Monitor server • Logging the alert details to a file • Logging the alert details to the Windows Event Log • Sending a Syslog message • Executing an external program • Executing a Visual Basic script • E-mailing a web page • Changing the value of a interface or node property • Playing a text to speech output • Sending a Windows Net Message • Dialing a paging or SMS service • Sending an SNMP trap • Posting a URL to a web server
