Group Member Context Masks

If is often necessary to select all group members for some kind of processing using a context mask. Here are some examples:

  • Making an alert that applies to the group members
  • Executing a query to fetch some data from group member contexts
  • Configuring an event filter to show only events that was generated by Devices participating in a certain group

To construct a mask that will match all group members, take group's context path and append a wildcard section (".*") in the end, e.g.: users.admin.alerts_groups.snmpAlerts.*

Example: If default administrator owns a device group called environment that includes all datacenter environment monitoring devices, use the following mask to match all group member Devices:

users.admin.devgroups.environment.*

This mask will be resolved to the list of member devices, e.g.:

users.admin.devices.temperature_sensor

users.admin.devices.humidity_sensor

users.ny_datacenter_operator.devices.smoke_sensor

users.ny_datacenter_operator.devices.spill_detector
