I dont have any experience with it besides homelab but Nagios Log Server is a virtual appliance built on ELK and has support for an arguably affordable price.

All the benefits of someone else building the ELK stack that everyone seems to love so all you see is 1 service instead of 3. Problem with the "service"? Call nagios etc.
They have a free version up to 500MB/day you can try out too.
