Quotas
The Quotas UI feature provides an overview of your current usage of resources within the respective Rollouts subscription, in particular those which are subject to quota.
For a detailed description of the general resource constraints and those specific to each service plan, please check here.
If you cannot find this UI feature on the left navigation, search for Quotas in Services and features, and then use the star icon to pin it to the main menu.
The different resource elements which are subject to quota are reported with their:
Name - the name of the resource which is subject to quota
Limit - the maximum number of such elements allowed for your service plan
Used - the number of such elements already used
Left - the number of such elements which are still available for use
Usage - a percentage report of the above
By default, the reported results are sorted by Usage in descending order. However, you can sort the results by each column in ascending or descending order.
In addition, you can adjust the columns displayed through the configuration icon 
in the top right area.
The Refresh icon 
in the top right area allows you to reload the quota report.
