Cloud Meta Element
The cloud meta element is used to change the meta information of a device on Atmosphere, such as a device’s geolocation or status. Device status is based on the following priority order, listed from highest to lowest:
Status can either be manually set or escalated using the above priority order. For status escalation, the status will increase to a specified state if it’s a higher priority than the device’s current status; otherwise the status will remain in its current state.
The cloud meta element is located in the Element Toolbox within Studio’s Cloud tab.
The following properties can be changed for the cloud meta element:
The name of the element.
The following triggers are available to execute events from within the cloud meta element:
Execute an event when the source element connected to the cloud meta triggers.
The following abilities are available for the cloud meta element when its source element triggers:
Trigger the element(s) that follow the cloud meta element.
Set the value of a custom meta tag.
|Set Value Arguments|
|Tag||String||Name of the meta tag.|
|Value||Object||Value to assign.|
Set the status tag for the device to be in an alarming state: alarming or not.
|Set Alarming Arguments|
|Value||Boolean||The argument will be true or false.|
Set Status to None
Set the device’s status to “none.”
Set Status to Good
Set the device’s status to “good.”
Set Status to Info
Set the device’s status to a user-selected input.
Set Status to Warning
Set the device’s status to “warning.”
Set Status to Critical
Set the device’s status to “critical.”
Set Status to Missing
Set the device’s status to “missing.”
Escalate Status to Good
Increase the device’s status to “good” if the current status is a lower priority level.
Escalate Status to Info
Increase the device’s status to “info” if the current status is a lower priority level.
Escalate Status to Warning
Increase the device’s status to “warning” if the current status is a lower priority level.
Escalate Status to Critical
Increase the device’s status to “critical” if the current status is a lower priority level.
Escalate Status to Missing
Increase the device’s status to “missing.”
Set Geolocation Position
Set the latitude and longitude of the device.
|Set Geolocation Arguments|
|Latitude||Float||The latitude of the device.|
|Longitude||Float||The longitude of the device.|
Atmosphere includes a selection of resources for users of all levels that demonstrate using the cloud meta element.
