Before you can use the Fleet Monitoring
plugin to monitor and offload from your vehicle system, you must define
your default, general, and automatic offload settings.
What you should know
You can choose the default type of information to offload: all data, or a subset to
reduce the bandwidth and storage needed by your offload archivers.
To handle the video
load in a large system deployment, multiple archiver roles can be used to offload
data. To avoid overloading a single server, AVL units need to point to specific
archiver roles on a per unit basis.
Procedure
-
From the Config
Tool home page, open the
Plugins task.
-
In the Plugins task, select the plugin role from the
entity browser, and click the Properties tab.
-
In the Default offload settings section, configure the
following:
- Destination archiver
- Default archiver for video archiver transfer. This should be dedicated for long-term
video storage.
- Offload video data on
- Offload video for all events, or for specific types of events. You can also specify
the duration, in seconds, of video preceding and following the events to offload.
- Automatic offload on
- Enable automatic offloads for the following:
- WiFi connected: If your vehicle system uses an embedded
WiFi adapter, start an automatic offload when your vehicle system connects to
WiFi.
- GPS unit online: Start an automatic offload when a GPS unit
goes online.
- Areas of interest: If you are using geofences to offload,
select the geofenced areas that you want to trigger automatic offloads when a
vehicle enters the area.
- Event on
- Trigger an event on the following:
- Automatic offload started: Receive events when automatic
offloads start.
- Automatic offload finished: Receive events when automatic
offloads finish.
- Offload failure: Receive events when automatic offloads
fail.
- Offload gap: Receive events when there is a gap between
automatic offloads.
- Require WiFi connection
- If your vehicle system uses an embedded WiFi adapter, only offload data using
WiFi.
- Require recent location data
- Only offload data if the location data of the AVL unit is recent.
-
In the General offload settings section, configure the
following:
- Prioritize manual offloads
- Send manual data offloads to the top of the queue.
- Chunk size
- Maximum video duration, in hours, that can be transferred before dividing it into
smaller chunks to optimize transfers.
- Maximum AVL units in progress
- Number of active transfers allowed simultaneously.
- Maximum items in progress per AVL unit
- Maximum number of items that can offload data at the same time during a transfer,
depending on the bandwidth available for offloading.
- Offload monitoring interval
- The update interval for data offloads in the AVL data offload
status task.
- Status page update interval
- The refresh interval, in seconds, for the AVL data offload status
task.
- Completed status timeout
- The duration, in minutes, before completed offloads are cleared from the AVL
data offload status task.
- Video offload pending timeout
- The duration, in minutes, before a pending video offload is canceled.
- Video offload in progress timeout
- The duration, in seconds, before an in-progress offload that is not sending status
updates is canceled.
- Offload incident titles
- You can define Security Center incidents that
are automatically generated during offload. This can make it easier to search and
investigate offloaded data.
-
In the Automatic offload settings section, configure the
following:
- Look back time
- Sets how far back to search for video to offload
- Maximum offload
- Maximum duration of data to offload
- Minimum offload
- Minimum duration of data to offload
- Overlap
- Ensures that there are no gaps between offloaded video.
- Offload order
- Set the order in which data is offloaded.
- Create incident
- Create an incident on automatic data offloads. If selected, set an Incident
title.
-
In the Map settings section, set the Stale data
threshold. The stale data threshold is the duration, in seconds,
before the icon of an inactive AVL unit changes to stale.
-
Click Apply.
