Look at major cloud providers and what they offer in monitoring such AWS CloudWatch, etc.

Be warned though there are a ton of monitoring solutions already. Hopefully yours has something special to bring to the table.

Be careful with hosted services like Amazon CloudWatch. They can get quite expensive if you log too many details. I think you can really save a lot of money with your own solution, eg using Prometheus / Grafana.
