Use this page to define gates.
A gate allows you to have only one device
that specifically monitors the entry to or exit from a zone.
When monitoring zones in areas, define the gate twice: once for the zone
and once for the area. Otherwise, Location Awareness Services for WebSphere® Premises Server cannot
correctly monitor tag counts for the zone and area.
Click Add to define a new gate, click an existing gate to edit it,
or select a gate and click Delete to delete it.
Add new gate
Complete
the following fields to create a gate:
Note: Before you can add a new gate,
you must have defined all devices for the associated event provider
from the Topology > Devices page.
- Name*: Enter a unique, meaningful name for the gate.
- Description: Enter a description of the gate.
- Area*: Select the area to associate with the gate.
Note: For scenarios
where proximity data (p-data) is used for tag positions, be sure that the
gate you define belongs to the area itself, and not to a zone within the area.
Otherwise, the tags may not be visible in the Spatial Management Client.
- Zone: Select the zone to associate with the gate. If no zone is
selected, the definition applies to the whole area.
- Hub*: Select the event provider to associate with the
gate.
- Device*: Select the name of the device you have already defined
using the Devices portlet.
- Role*: Select the role of the gate.
- Select IN to specify that the associated device monitors tags entering
the gate. When the device sees a tag in the associated zone, it considers
the tag to be inside the zone. The coordinates of the tag are those reported
by the location event provider. An event or alert is logged to indicate that
the tag left the zone.
- Select OUT to specify that the associated device monitors
tags exiting the gate. When the device sees a tag, it considers the tag to
be outside of the zone being monitored. An event or alert is logged to report
that the tag left the zone.
- Select IN/OUT to specify that a tag is:
- Logged in to the zone associated with the device as long as it is "seen"
by this device only
- Logged out if it is not seen by the device anymore (after some delay)
or if it is seen by any other devices
