On the Settings > My Subscription page, USM Anywhere displays the total data you have consumed for the month, the remaining data to be consumed, and the projected data you will consume based on your current usage. The service tier specified on your license determines the amount of data you're allowed to consume each month.
The Projected Data Consumption field is calculated using the following formula:
projectedMonthlyConsumption = (currentMonthDataConsumption / totalDaysOfDataConsumption) * DaysInMonth
- currentMonthDataConsumption = total data consumed in the current month.
- totalDaysOfDataConsumption = the number of days passed in the current month (includes days with no recorded data).
- DaysInMonth = total number of days in the month.
For example, in a 30-day month, if at the end of the 15th day the instance has received 10 TB of data, the projected data consumption will be (10 TB / 15) * 30 = 20 TB.
The Projected Data Consumption field is crucial because it provides an estimate on how much data you will consume by the end of the month. This number should never exceed your allocated monthly usage. Exceeding the monthly limit turns USM Anywhere into transient mode, where incoming events are no longer searchable. More importantly, USM Anywhere's performance deteriorates. System process time increases, causing the sensor cache to fill up and the sensor to disconnect.
AT&T Cybersecurity recommends that you monitor your projected data consumption early and constantly, so that you can perform countermeasures when you're to exceed your monthly limit. You can reduce consumption by monitoring fewer networks, cutting down the number of data sources, or creating filtering rules to restrict data collection.
On the same My Subscription page, there is a Total Event Data chart that displays the data collected during the current period. When you click View Data Consumption by Data Source, a chart displays showing the breakdown of how much data is being used by each data source. You can click the Export to CSV button beneath the chart to create a comma-separated value (CSV) file detailing the data consumption in a spreadsheet.
