Eliminate the complexity of manual Nagios® Core™ deployment. This pre-configured AMI from Cloud Infrastructure Services delivers a production-ready Nagios Core monitoring server on Ubuntu 22.04, letting DevOps teams and IT operations managers begin monitoring AWS infrastructure within minutes rather than hours of manual setup.
