I have been trying to get the Pushover Transport Notification information to show as HTML to match the email layout.
Every time the alert triggers in Pushover I see all the HTML code.
According to the Pushover API documents, pushover support HTML if you specify the html=1 option. I have tried this via the LibreNMS transport gui and also setting via config.php but neither seem to work.
the best way is to make a pull request to add your html support in. Otherwise I think you can add it at the end of .gitignore, or delete it altogether with scripts/github-remove and then re-run daily.
