Redis® is an in-memory database that provides blazingly fast performance. This makes it a compelling alternative to disk-based databases when performance is a concern. Redis returns a big list of database metrics when you run the info command on the Redis shell. This blog post lists the important database metrics to monitor.

Compared to intrusion detection systems (IDS/IPS), WAFs are focused on the application traffic. For most enterprises, using a RASP solution would mean running multiple agents on their production systems, potentially creating risk due to incompatibilities. WAFs protect the network perimeter and monitor, filter, or block HTTP traffic.
