Event Policy Overview

In response to events, event policies can execute the following actions:

• Ignore the event—Do not generate a system log message for this event and do not process any further policy instructions for this event.
• Raise a trap—Initiate an SNMP trap to notify SNMP trap-based applications when the event occurs.
• Upload a file—Upload a file to a specified destination. You can specify a transfer delay, so that, on receipt of an event, the upload process begins after the configured transfer delay. For example, a transfer delay can ensure that a core file has been completely generated before being uploaded.
• Execute CLI operational mode commands—Execute commands when an event occurs. The output of these commands is stored in a file, which is then uploaded to a specified URL.
• Execute operation scripts—Execute operation scripts when an event occurs. The output of the operation scripts is stored in a file, which is then uploaded to a specified URL. For information about operation scripts, see Automating Network Management and Troubleshooting with Operation Scripts.
