ThousandEyes customers who use Cloud Agents have a monthly allotment of units to allocate for tests assigned to those agents. The number of Cloud Units per month is specified in the customer's contract. Customers can be kept up to date on current and projected future usage through the Usage tab of the Account Settings page. Additionally, the ThousandEyes platform automatically warns the user through the Notifications menu of the app, as well as emailing the warnings to an organization's billing contact.
Information on units and the formula to calculate the units used by a given configuration of a test can be found in How Unit Consumption Works.
The Usage tab displays the number of Cloud Units used to date in your monthly billing cycle. Additionally, in order to maximize your use of the platform without incurring additional charges or hitting usage limits, ThousandEyes provides a projection of the units which will be used by the end of your billing cycle, based on your unit consumption to date, the rate you are currently using units, and the time remaining in the monthly billing cycle.
In mathematical terms, the projected units, , are calculated by adding the amount of units consumed since the beginning of the cycle,, to the units per month cost of the currently configured tests,, multiplied by the fraction of the rounds remaining in the month divided by total rounds in the month:
Rounds in usage calculation are 15-minute intervals, used as the basic unit of time to handle calculations with fractions of a day. There are 96 rounds in a day (1 round/15 minutes x 1440 minutes/day).
Information on the number of Cloud Units consumed is updated every six hours.
The top panel of the Usage tab displays the date range of your billing cycle. Unit usage is displayed as the actual units used relative to your total monthly unit allotment. Included there is the projection of the units which will be used at the end of the current monthly billing cycle, per the above formula.
In the above example, as of the current date, this organization has used 50% of its total unit monthly allotment for the period April 1st to May 1st (a 30-day billing cycle). At the current rate of unit usage, the organization is projected to use 83% by the end of the billing cycle.
The second panel of the Usage tab contains two tabs: Cloud Unit Breakdown and Enterprise Agents Breakdown. The former displays current usage breakdowns by account group, test type, and test, and optionally breakdowns of the full month's estimated usage.
The Enterprise Agent Breakdown tab shows usage of Enterprise Agents by account group:
The following levels of projected and actual use by the organization will result in an email sent to the organization's billing contact:
Estimated usage is greater than 100%
Actual usage exceeds 90% AND the estimated usage is greater than 100%
Actual usage exceeds 100%
If your projected or actual use exceeds 100%, you may wish to reduce the number of tests, investigate tests that have lower unit costs that can still meet your testing requirements, or have fewer Cloud Agents running the tests. Using the metrics on the Usage tab, admins can locate the largest sources of unit consumption.
NOTE: Only users who have been assigned a role with the View billing permission can view the Billing tab. Only users who have been assigned a role with the View organization usage permission can view the Usage tab.
NOTE: The billing contact Email field can only accommodate a single email address. To distribute billing contact emails from ThousandEyes to multiple recipients within your organization, we recommend creating a distribution list within your organization and entering the distribution list's email address in the Email field of the billing contact information. Make sure that senders outside your organization have permission to send email to the distribution list.
