# System Tags
# Concept
To help distinguish between high level groups of usage data, Cloud View - Data#3 injects (for certain vendors) some additional tags with each row of usage data. These system tags can be used in a number of places within Cloud View - Data#3 including reports, filters, and the tag hierarchy.
The current available system tags are
- $ResourceGroup (Azure only)
- $AzureSubscriptionName (Azure only)
- $AzureSubscriptionId (Azure only)
