What happens when you use debug logs?
Most devices will generate an order of magnitude greater log volume when set to the Verbose or Debug logging levels. The result of this is system impacting on multiple fronts with the most critical being processing via the MPE and indexing via the Data Indexer (DX). Specifically, while Verbose and Debug logs will inevitably hit Catch All rules, they will not only cause an immense MPE slow down, but also many stalled/disabled rules, spooling, and overall poor performance as they attempt to process through every rule in the policy. In addition to this, indexing will be impacted, whereas the logs cause a backup of spooled reliable persist files, resulting in poor DX performance.
