Which licensing aspect is managed by the Event Collector in QRadar?

The Event Collector in QRadar plays a vital role in managing licensing aspects related to the number of events processed. Specifically, EPS, or Events Per Second limits, are crucial for determining how many events the system can handle within a given timeframe. This limit directly affects the system's ability to scale and manage the data influx from various sources.

By monitoring EPS limits, the Event Collector ensures that the organization remains compliant with its licensing agreements while optimizing performance. This is important because exceeding the EPS limit can lead to issues such as dropped events or degraded system performance, ultimately affecting the effectiveness of the SIEM solution in detecting and responding to security incidents.

In contrast, aspects like storage limits refer to how much data can be retained on the system, while event processing limits encompass the overall capabilities of the system regarding how it processes data—factors that are generally managed by other components in the QRadar ecosystem. Performance limits typically refer to the system's operational efficiency rather than a specific licensing measurement, which is why these options are not the best fit for this particular function of the Event Collector.
