Nagios Core is the industry-leading open source monitoring solution trusted by IT teams worldwide.

Why This AMI Over a Vanilla Nagios Install?
Deploying Nagios Core from scratch requires installing dependencies, configuring Apache, setting up CGI permissions, and tuning check intervals - a process that can take hours. This AMI eliminates that setup burden with a production-ready configuration that includes the Nagios web interface accessible via your browser, core monitoring plugins pre-installed, and service definitions ready for customization. You go from AMI launch to your first monitoring check in minutes, not hours.
Who This Is For
This AMI is built for sysadmins, NOC engineers, and DevOps teams who need reliable infrastructure visibility - whether you are a small team monitoring50 EC2 instances or a managed service provider tracking uptime SLAs across multiple client environments. It suits hybrid AWS environments where you need to monitor both cloud resources and on-premises legacy servers from a single dashboard.
Network and Infrastructure Monitoring
Monitor routers, switches, firewalls, and network services using SNMP and ICMP checks via plugins. Track bandwidth, port availability, and link status across your entire network topology. For servers, monitor CPU usage, memory consumption, disk space, load averages, and process health - gaining visibility into resource utilization before problems escalate into outages.
Alerting and Notifications
Configure multi-channel alerting through email, SMS, and custom notification scripts. Define escalation policies so the right team members are contacted at the right time. Set alert thresholds, schedule maintenance downtime windows, and use contact groups to route notifications by severity and responsibility. The result: faster incident response and fewer missed outages.
Plugin Ecosystem
Nagios supports over 4,000 community and custom plugins available through Nagios Exchange. Monitor HTTP, HTTPS, FTP, SSH, databases, mail servers, DNS, and virtually any service with a network endpoint. Develop custom plugins using standard interfaces, or leverage NRPE for agent-based checks on remote hosts.
Web Interface and Performance Data
Access a full web-based dashboard showing real-time host and service status, status maps, alert history, and notification logs. Performance graphing provides historical metrics, trend analysis, and capacity planning data - helping you make informed decisions about scaling your infrastructure.
Distributed Monitoring
Scale beyond a single server with distributed monitoring architecture. Use NRPE agents for remote active checks, NSCA for passive check submission, and SSH-based checks for secure remote monitoring. Monitor thousands of hosts across multiple locations from a central interface.
Example Use Case
A DevOps team of three engineers monitors 50 EC2 instances running a microservices application. They configure Nagios to check HTTP endpoints every 60 seconds, monitor RDS database connections, and track EBS disk utilization. When CPU on any instance exceeds 85% for five minutes, Nagios sends a Slack notification via webhook. The team catches capacity issues before customers experience slowdowns, maintaining their99.9% uptime SLA.
