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® Sensor Events 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 event provider. An event or alert
is logged to indicate that the tag entered 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
