# group
## Description
-
+A list of sensor object names to include in determining trust of their values based on the configured [`class`](class.md). These sensors are what's included in the group that then has all of their current values trusted or not for monitoring based on algorithm of the [`class`](class.md).
## Attribute Value(s)
-
+* `name` - string
+ * The name of the fan tach sensor located under the `/xyz/openbmc_project/sensros/fan_tach` D-Bus path.
+* `in_trust` - boolean (Optional)
+ * By default, the sensor is included in determining trust of the group.
+ However this can be used to cancel/restart monitoring of a fan tach sensor
+ but not have it included in the determination of trust.
