# System Tags
# Concept
To help distinguish between high level groups of usage data, Cloud Ctrl 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 Ctrl including reports, filters, and the tag hierarchy.
The current available system tags are
- $ResourceGroup (Azure & Rhipe only)
- $Customer (Rhipe only)
- $AzureSubscriptionName (Azure only)
- $AzureSubscriptionId (Azure only)
