 ## Can I disable a monitor during scheduled maintenance or upgrade window?
 
 Yes. See [Muting Schedules](/docs/alerts/monitors/muting-schedules) to learn how to pause alert notifications from monitors according to a schedule defined by you.
+
+## Why does a disabled monitor generate scan usage when I view or edit it?
+
+When you open or edit a monitor, even if it’s disabled, the system needs to evaluate its query and thresholds to display accurate information. This includes loading preview charts, validating configuration details, or updating threshold visuals. These actions require running the underlying query, which triggers scan events and therefore consumes credits. The scans may also occur when you use the **View in Metrics Search** feature, as it executes the monitor’s query against your data to display results.
+
+### How can I avoid unexpected scan charges for disabled monitors?
+
+- Limit opening or editing monitors unless necessary.
+- Avoid using preview or **View in Metrics Search** features if you want to minimize scans.
+- Copy the query into a separate environment (like Metrics Search directly) if you only need to inspect it without refreshing UI previews.
