I have some notification rules configured that take advantage of the ability to add a screenshot of a pi vision display into the email. However, I've been having some issues with the performance of these screenshots.
To preface, I've already done a bit of troubleshooting to get the notifications working. I've created an identity called "Notifications" that is handling the PI Vision Display security. I've added the PI Vision server as a trusted site on the PI AF Configuration.
With this, the notification sometimes works:
However it often doesn't work, and returns the display with little or no data shown:
I've been trying to figure out why it doesn't work more often than not, I thought maybe it's timing out on the data retrieval, but I've tried adjusting the timeout setting on the page render attribute, and after testing that doesn't seem to have made any difference (using the test send button on system explorer).
This is the question response that I was trying to use to help troubleshoot: https://pisquare.osisoft.com/thread/35461-trend-in-pi-notification-2017-r2
Are there any other troubleshooting tips anyone can recommend? I'm thinking it's probably not a permissions issue if it sometimes works. Any help would be appreciated.
