"The view snapshot in this email could not be properly rendered."If you receive a subscription with this error message, there could be several reasons: Show
Can't see images in emailFor images of content to display in a subscription email, users subscribed to views, in addition to View permissions, must also have Download Image/PDF permissions. For more information, see Permissions. Can't subscribeIf you can see a view on Tableau Server and it has a subscription icon ( ) in the upper right corner, you can subscribe to it.To subscribe to a view, Tableau Server needs to be correctly configured (described in Manage Subscriptions(Link opens in a new window)) and the view you're subscribing to must either have embedded credentials for its data source or not rely on credentials at all. Examples of the latter include a workbook that connects to an extract that isn't being refreshed, or a workbook whose data is in a file that was included with the workbook at the time of publishing. Embedding credentials is a step that happens in Tableau Desktop (see the Tableau Help(Link opens in a new window) for details). No subscription iconIt's possible to see a view but be unable to subscribe to it. This can happen for several reasons:
Receiving invalid or "broken" subscriptionsIf you configured subscriptions on test or development instances of Tableau Server in addition to your in-production instance, disable subscriptions on your non-production instances. Keeping subscriptions enabled on all instances can result in your users receiving subscriptions that appear to be valid, but that don't work, or receiving subscriptions even though they've unsubscribed from the view or workbook. Missing PDF attachmentYou can add a PDF attachment to your subscription if your administrator has it enabled. If the PDF attachment is missing from your subscription, it might be because the size of the PDF exceeds either the email server size limit or the maximum size limit set by server administrators. In Tableau Server, the maximum size limit for PDF attachments to subscriptions can be adjusted through the tsm configuration option subscriptions.max_attachment_size_megabytes. For more information, see Configure Server Event Notification and Set Up a Site for Subscriptions. Suspended SubscriptionsBy default, a subscription is suspended after 5 consecutive subscription failures. To change the threshold number of subscription failures that can occur before they are suspended, use the tsm configuration set option, backgrounder.subscription_failure_threshold_for_run_prevention. This sets the threshold for the number of consecutive failed subscriptions necessary before suspending the subscription. This is a server-wide setting. Only Server administrators can configure the threshold number of subscription failures before a subscription is suspended. For information on setting this threshold, see Set up a Server for Subscriptions. By default, administrators are not emailed when a subscription is suspended, but can opt-in to suspension emails per site through My Account Settings. Resume suspended subscriptionsAdministrators and subscription owners can resume subscriptions in several ways:
When a subscription is resumed, the alert failing count goes back to zero. The next evaluation of the subscription will occur at the next scheduled evaluation time. Can't set subscription frequency to "When Data Refreshes"You can set subscriptions to run when an extract refreshes if the workbook uses a connection to a published extract. When creating or modifying a subscription, you might not see a Frequency option if the workbook uses:
Subscriptions not arriving ("Error sending email. Can't send command to SMTP host.")You may see the above error in Windows Event Viewer if subscriptions aren't arriving and your SMTP server is using encrypted (TLS) sessions. To send subscriptions to an SMTP server that is configured with TLS, you must configure secure SMTP on Tableau Server. See Configure SMTP Setup. (If you're experiencing this error, note that Tableau Server will still indicate that subscriptions are being sent in the Background Tasks for Non Extracts(Link opens in a new window) admin view.) Missing data quality warningsData quality warnings are included in subscription emails when:
Custom scripts not working after upgrade to 8.1To support better session management, starting with version 8.1, a hash tag (#) was added to the end of view URLs. If you had custom subscriptions scripting that generated views as PDFs or PNGs you may need to update your scripts to allow for the hash tag. For example, prior to version 8.1, view URLs use this syntax: http://tableauserver/views/SuperStore/sheet1. To generate a view as a PNG, .png could be added to the end of the URL. For example, http://tableauserver/views/SuperStore/sheet1.png. In versions 8.1, 8.2, or 8.3, view URLs use this syntax: http://tableauserver/views/SuperStore/sheet1#1. To generate a PNG, add .png before the hash tag. For example: http://tableauserver/views/SuperStore/sheet1.png#1 Custom scripts not working after upgrade to 9.0In version 9.0, the session ID at the end of server URLs is indicated by an "iid" parameter, :iid=<n>. For example, http://localhost/#/views/Sales2015/SalesMarginsByAreaCode?:iid=1. This parameter replaces the hash tag "#<n>" used for the session ID in 8.x versions of Tableau Server. If you use custom subscriptions scripts that generate views as PDFs or PNGs, you may need to update your scripts by removing the hash tag and number (#<n>), and inserting the ?:iid= session ID parameter before the number. Starting in version 9.0, view URLs use this syntax: http://tableauserver/views/SuperStore/sheet1?:iid=2. To generate a PNG in version 9.0 and later, add .png before the session ID: http://tableauserver/views/SuperStore/sheet1.png?:iid=2 Which Windows system recovery options attempts to automatically fix problems?If Windows won't boot, you can use the Startup Repair option to automatically fix problems.
How do I restore a previous version of Windows?Right-click the file or folder, and then click Restore previous versions. You'll see a list of available previous versions of the file or folder. The list will include files saved on a backup (if you're using Windows Backup to back up your files) as well as restore points.
What is Windows 10 Restore?System Restore is a Microsoft® Windows® tool designed to protect and repair the computer software. System Restore takes a "snapshot" of the some system files and the Windows registry and saves them as Restore Points.
How can you enter the Windows Recovery Environment to recover from the Update?Entry points into WinRE. From the login screen, click Shutdown, then hold down the Shift key while selecting Restart.. Click Start > Settings > Update & security > Recovery > under Advanced Startup, click Restart now.. Boot to recovery media.. Use a hardware recovery button (or button combination) configured by the OEM.. |
