Getting Started

The purpose of this guide is to quickly bring you up to speed with the Advanced Device Management extension. To do so, we will cover four key sections:

Section 1: Understanding Tasks

A device task represents a specific action to be performed on the device and the resulting response from executing the task. Every command executed on the device via the ADM extension is considered a task. These tasks are defined through the ADM extension and are downloaded to the device for execution. The following tasks can be executed.

Monitoring Tasks

Monitoring tasks are used to regularly query device attributes to effectively provide you with consistant periodic information about the device. Listed below are a few samples of monitoring tasks:

  • Get CPU Load
  • Get Memory Usage
  • Get Storage Usage
  • Get Total Uptime
  • Get Display Resolution

While the ADM extension provides you a flexible framework to execute commands across a wide range of protocols, the command will need to exist on the device itself in order for it to be usable.

Advanced Tasks

An advanced tasks represents a specific action (e.g. reboot device) to be performed on the device while having the ADM extension display all resulting responses from the deployed task. Listed below are a few samples of advanced tasks:

  • Install Font Pack
  • Install/Update Device Driver
  • Deploy Firmware Update
  • Retrieve Logs
  • Reboot Device

Device Configuration Tasks

Device configuration tasks allow you to apply configuration parameters and/or settings to a single device or group of devices within a network. Listed below are a few samples of device configuration tasks:

  • Set NTP Server Address
  • Set Proxy Server Address
  • Set Download Speed
  • Set Display Resolution
  • Set Display Orientation

Section 2: Task Templates

Task templates are user-defined templates that contains commands to be executed on a device. Templates simplify the process of sharing complex commands, parameters or transform combinations as data can be easily migrated out of one Appspace instance and into another. You have the option of using the pre-configured task templates or importing your own.

Using the Pre-Configured Task Templates

Out of the box, the ADM extension does not contain any task templates. However, there’s a collection of pre-configured task templates aimed to quickly help you configure and monitor your devices. Listed below are some selected task templates.

Monitoring Tasks

Note

To download the collection of pre-configured task templates, click here. The task templates will be downloaded as adm_task_templates.admpkg.

Importing a Task Template

After you’ve downloaded the collection of pre-configured task templates shown in the previous section, you can proceed to import them into the ADM extension.

Step 1

From the Task Templates tab, click the Import button.


Step 2

Click the browse button and browse for the task templates. Click Upload to upload the task templates.

Note

When importing, always ensure that the package is a valid .admpkg file generated by the extension and not an externally modified file.

Section 3: Task Examples

While new users are encouraged to use the pre-configured task templates, advanced users can choose to write their own tasks to achieve certain outcomes. This section covers a few advanced, monitoring and device configuration task examples.

Monitoring Tasks

Example 1: Get Memory Usage

This task retrieves the current memory usage of the target device.



Type: HTTP/S
Method: Get
URL: http://127.0.0.1:7777/get_param?p=sinfo.memory
Parameters: None

Note

  • A full list of available DMP 4310/4400 MIBs parameters can be obtained from http://{DMP IP}/get_param?p=*.
  • The URL used in this task definition points to localhost (127.0.0.1) as the task is executed on the device itself.

Example 2: Retrieve Download Manager Log

This task uploads the downloadmanagerlog.txt to a handler in Appspace. The user is able to download that log file for troubleshooting purposes.


Type: Shell
Device: Edge 340
Command:
  curl --upload-file /apps/nexus2/Logs/downloadmanager/txt -X POST"{{ENV-APPSPACE_URL}}/api/v1/core/tasks/payload/stream/upload?
  filename=downloadmanagerlog.txt&clientguid={{ENV_PLAYER_GUID}}&deployedtaskid={{ENV_TASK_ID}}"
Parameters: None

Note

All ENV parameters defined in the example shown are environment-defined parameters that will be evaluated during task execution and finally replaced with device-dependent values

Advanced Tasks

Example 1: Switch between Player and Desktop mode

This task switches the device’s mode between player and desktop.


Type: Shell
Device: Edge 340
Command: ./apps/nexus2/switchmode.sh {{mode}} && reboot
Parameters: mode (user defines player or desktop mode during deployment)

Example 2: Replace a file on Device (using nexusmediaplayer.swf)

This task can be divided into two parts:

The first part copies/backs-up the original nexusmediaplayer.swf and uploads it to Appspace. You will be able to retrieve the file when this task is deployed.

The second part replaces the backed-up nexusmediaplayer.swf file with another nexusmediaplayer.swf file that’s located on a local server with a local IP. The parameter defined is local_ip and upon deploying this task, the user will be asked to set the IP of the local server.


Type: Shell
Device: Edge 340
Command:
  curl --upload-file /apps/nexus2/nexusmediaplayer.swf -X POST"{{ENV-APPSPACE_URL}}/api/v1/core/tasks/payload/stream/upload?
  filename=downloadmanagerlog.txt&clientguid={{ENV_PLAYER_GUID}}&deployedtaskid={{ENV_TASK_ID}}"

  wget -O /apps/nexus2/nexusmediaplayer.swf http://{{local_ip}}/nexusmediaplayer.swf
Parameters: local_ip (user defined during deployment)

Device Configuration Tasks

Example 1: Set Log Size

This task sets the log size on the device.


Type: HTTP/S
Method: Put
URL: http://127.0.0.1/api/sys/log/size
Header: Content-Type=application/json;password={{ENV_DEVICE_PASSWORD}}
Body: {"size":"{{size}}"}
Parameters: size

Note

Example 2: Set NTP Server

This task sets the NTP server of the device.


Type: HTTP/S
Method: Get
URL: http://127.0.0.1/api/sys/ntpServer
Header: Content-Type=application/json;password={{ENV_DEVICE_PASSWORD}}
Body: {"ntpServer":"{{server}}"}
Parameters: server

Note

Checklist

At this stage, you would have already:

  • Understood the concepts of tasks
  • Imported the collection of pre-configured task templates
  • Seen a few examples of custom written templates

The next thing you’ll want to do is to deploy your task to your device.

Section 4: Deployment and Response

A task is deployed when the device receives and executes it. Upon executing a task on a device, the advanced device management extension will feed back all responses from the device through the extension’s interface.

After you’ve selected your desired task template, you’ll now want to deploy that task to your Appspace registered device.

Deploying your Task and Getting a Response

Step 1

From the Advanced Tasks tab, click on the + button to deploy a task.


Step 2

Select one of the task templates from the list in the overlay window and click select.


Step 3

Under the Deploy To section, click the + button to select a location/device to deploy to.


Step 4

From the network tree, select the network, player group or specific device you would like to deploy the task to. Click Select to confirm your selection.


Note

An application needs to be assigned to the device before you are able to deploy a task.

Step 5

Select your deployment schedule and click save.


Step 6

To display the output of the task, click the response of the deployed task.


Step 7

A pop-up will display the raw and transformed (if any) response.
