Nagios Core is a host, service, and network monitoring program written in C, with CGI-based web interface for viewing status and history. It supports plugin-based monitoring methods, host hierarchy definitions, and alert notifications via email, pager, or custom methods.

Use cases

• monitor network services like SMTP, HTTP, and PING
• watch server resources such as CPU load and disk usage
• get alerted when hosts go down or recover
• set up a self-hosted infrastructure monitoring dashboard
• extend monitoring with custom plugins
• track notification and problem history over time

When to choose

• you need a battle-tested, self-hosted monitoring solution with a large plugin ecosystem
• you want fine-grained control over host/service checks and alerting
• you prefer a lightweight C-based core without heavy runtime dependencies

When to avoid

• you want modern dashboards and metrics out of the box (consider Prometheus/Grafana)
• you need agent-based auto-discovery and cloud-native integrations
• you prefer not to maintain CGI web interfaces and config-file-heavy setups
