Installing the Image Creation ServicePrevious


Overview

Dundas Dashboard lets you share a completed dashboard as a dashboard image, or attach an image of a dashboard to an email message as part of the notifications feature.

To enable the above features on your Dundas Dashboard server, you must install the Dundas Dashboard Image Creation Service, either on the same Dundas Dashboard server, or a separate server computer.

This article shows how to perform manual configuration of both the Image Creation Service and Dundas Dashboard after completing the installation of the service. The basic idea here is that the Image Creation Service must be able to reference the Dundas Dashboard instance, and vice-versa.

Tip: You can skip this step if you installed the Image Creation Service on the same computer where Dundas Dashboard is installed, and you did not choose the manual option for specifying the Dundas Dashboard instance. The ImageCreationWin.exe.config file needs to be updated only when the manual selection of the instance is done. On automatic selection of the instance, the ICS gets installed and after the website restart, it gets reflected in the application, but this file is not updated with the details. However, the ICS can still be used even without seeing any changes in this file.

Configuring the Image Creation Service

Configuration of the Image Creation Service is controlled via an XML file located on the image creation server (which may be the same computer where Dundas Dashboard is installed). The default path of this configuration file is:

C:\Program Files (x86)\Dundas Data Visualization Inc\Dundas Dashboard\Image Creation Service\{InstanceName}\ImageCreationWin\Dundas.Dashboard.ImageCreationWin.exe.config

An example configuration file is listed below. In this particular case, the Image Creation Service is installed on the Dundas Dashboard server computer.









The relevant keys in this configuration file are described as follows:

  • dundasDashboardUrl - The URL of the Dundas Dashboard instance that will be linked to this image creation service.
  • imageCreationHostUrl - The URL of the Image Creation web service (on the image creation server).

If you modify any of the key values in the configuration file, you must restart the Dundas Dashboard Image Creation service for the changes to take effect.

Configuring Dundas Dashboard

The Dundas Dashboard Configuration File (located on the Dundas Dashboard server) has a block of settings dedicated to the configuration of the image creation functionality. The default path of this configuration file is:

C:\Program Files\Dundas Data Visualization Inc\Dundas Dashboard\{InstanceName}\www\Dundas.Dashboard.config

The relevant portion of an example configuration file is listed below.

The relevant keys in this configuration file are described as follows:

  • imageCreationServiceUrl - The URL of the Image Creation web service (on the image creation server).

If you modify any of the key values in the configuration file, you must restart the Dundas Dashboard website for the changes to take effect.

FAQs and troubleshooting

Logging

Q: Where can I find the Image Creation Service Log?

A: The Dundas Dashboard Image Creation Service logs directly to the Event Viewer.

To go to the Event Viewer, click Start, point to Control Panel, open Administrative Tools, then open Event Viewer.

Option to share as dashboard image is not present

Q: Why can't I see the “Share this dashboard or a single dashblock as a dashboard image” option in the Share dialog?

A: You must restart the Dundas Dashboard website after installing the image creation service.

Run the image creation service as a different user

Q: Can I run this service as a different user?

A: You can, but in order for it to work correctly we recommend the following settings:

  • User should be a member of the administrators group.
  • User should be granted the “Log on as a service right”
  • User needs to have isolated storage to the service address.

To grant this storage, do either of the following:

  • Run the following application as the user that will run the service: Dundas.Dashboard.ImageCreationWin.exe /RequestIncreaseQuota
  • Log into your server using the user which is configured to run the Image Creation Services, view a dashboard, and this will prompt you to increase storage space.

Q: Why am I receiving a blank image when sharing an image of the dashboard?

A: Silverlight is running out of storage to display the image (error code is -10 in Windows Application Event Log). You will need to increase the storage space.

Timestamps

Q: Why are the timestamps on my shared images displayed in a different format than other dates and times shown on my dashboard?

A: The timestamps are displayed using the region and language settings as specified by the ddimage user account that runs the image creation service. These settings may be different than those on your Dundas Dashboard server.
