28: Event system
_______________________________________________________________________________________________________
28 Event system
Virtual Access routers feature an event system.
The event system allows you to configure the router’s information for efficient
control and management of devices.
This section explains how the event system works and how to configure it using
via UCI.
28.1 Implementation of the event system
The event system is implemented by the va_eventd application.
The va_eventd application defines three types of object:
Forwardings
Rules that define what kind of events should be generated. For
example you might want an event to be created when an IPSec
tunnel comes up or down.
Targets
Define the targets to send the event to. The event may be sent
to a target via a syslog message, a snmp trap or email.
Connection
testers
Define methods to test the target is reachable. IP connectivity
to a server and link state may be checked prior to sending
events.
For example, if you want to configure a snmp trap to be sent when an IPSec
tunnel comes up, you will need to:
• Define a forwarding rule for IPSec tunnel up events
• Set an SNMP manager as the target
• Optionally using a connection tester to ensure the SNMP manager is
reachable
28.2 Supported events
Events have a class, a name and a severity. These three properties are used to
fine tune which events to report.
28.3 Supported targets
The table below describes the targets currently supported.
Target Description
Syslog Event sent to syslog server
