OnAttachmentEvent
Summary
Indicates that the attachment status has changed for an
This event is generated whenever a device or router is
attached to the network. Once an AppDevice or Router has
been attached, it is monitored via periodic pinging to ensure
that it remains attached. If the ping fails, indicating that the
device or router is no longer attached, this event will be
generated to indicate this.
Note: OpenLNS will check to make sure that the ping failure
is due to a failure on the device or router being pinged, and
not because of a failure on another router on the
communications path between the OpenLNS Object Server
and the router or device in question. The rate at which a
device or router is pinged is determined by its PingClass
property.
This event is fired when changes are made to the physical
network. The OnChangeEvent is fired when those changes
are made to the OpenLNS database. You can subscribe or
unsubscribe your application to these events using the
object’s BeginAttachmentEvent and
EndAttachmentEvent methods.
For more information on the OnAttachment event, see the
Testing Devices and Detecting Device Failures section in the
OpenLNS Programmer’s Guide.
