This repository contains custom Nagios plugins developed by the BlueGrid Platform Engineering Team to extend monitoring capabilities for various infrastructure components.
A Nagios-compatible plugin that checks the operational status of critical services on CDN servers.
It verifies dependencies between services to ensure that:
- The server is fully ready for production, with all required services running, or
- The server is safely out of production, with critical services stopped as expected.
Specifically, it monitors:
- Host reachability (ping)
- MySQL database status (active flag)
- Routing service (Bird) status
- HTTP services (Nginx, Varnish)
- DNS resolver (Unbound) for DNS servers
Based on the combination of these checks, it reports an OK, Warning, or Critical state and returns the appropriate Nagios exit code.
