Assess peak log events per minute requirements

The performance tests/assessments have been based on staging environments so far and the production load is going to be significantly higher - to ensure the system can cope, the production peak log events per minute should be known to allow for appropriate test scenarios.

While inquiring the operations team is in progress already via @mrdavidlaing, an alternative approach would be to deduce this from a relevant log dataset - however, given this sensitive data can't leave the firewall,  a respective analysis script for BTF usage is required.
