Three different questions, answered in three different places: is it connected, is it showing the right content, and is the hardware in trouble.
Monitoring
Knowing that a screen is up, that it is showing the right thing, and that the device behind it is healthy.
In this section
Status and sync
How often a screen checks in, what online and pending sync actually mean, and why a command sometimes takes a few minutes to land.
Screenshots
Seeing what a screen is actually showing, why a screenshot is sometimes unavailable, and how to turn capture off entirely.
Health and diagnostics
The Details tab turns a device report into a ranked list of problems, each with what caused it and what to do. What it checks and what the thresholds are.
Alerts
Getting told when a screen goes offline, by email, Slack, or PagerDuty, and how to keep the alerts worth reading.
