Your environment has a limited data consumption tier depending on your subscription tier.
Important: Tier options do not have unlimited processing power, memory allotment, or disk input/output (I/O) speeds. In addition to storage per month, your deployment size's impact on any of these factors will influence which tier option is right for your environment. AT&T Cybersecurity recommends pre-deployment sizing discussions with your sales representative to help select the right tier for you.
Note: If the events per second (EPS) threatens to impact your sensor's capacity. USM Anywhere may engage EPS Adaptive Response. EPS Adaptive Response enables your system to take more time to process events coming in by throttling your EPS, which keeps your system running without risking event loss. See Protecting Your Sensor's Performance with EPS Adaptive Response to read more about EPS Adaptive Response.
If your environment is going to exceed your data consumption tier, a yellow announcement displays in your USM Anywhere to warn you about it. All users can see this yellow announcement in your environment, and you can close it by clicking the icon in the upper-right side of the page.

To refrain from reaching your monthly limit, AT&T Cybersecurity recommends that you create filtering rules to restrict data collection. If you've reached the monthly limit, you can purge your earliest seven days of data from the current month through the My Subscription page. This can be done twice a month. The button to purge data will only be active after you have reached your limit and your system is operating in transient mode. If you purge data to go back under your data limit, the transient mode will end as of the date that you enacted the purge. The purge won't retroactively remove transient mode for the days that the limit had been exceeded.
To purge seven days of event data
- Go to Settings > My Subscription.
Click Purge 7 Days of Event Data.
The purge event data dialog box opens.
- Click Purge.
Note: The 7 days of event data refer to the first 7 days of the current month. If you choose to purge again in the same month, then the second 7 days will be purged (the 8th of the month through the 14th).
