check_expiration_rdap

Project Notes

Checks how far a domain is from expiring. Uses Registration Data Access Protocol (RDAP, supporting IANA DNS bootstrap) as the primary source.

Version 0.2 adds a fallback for .ar domains: when RDAP transport, HTTP, JSON, or expiration-event lookup fails, the plugin queries NIC Argentina WHOIS with whois -h whois.nic.ar and parses the expire: field.

Existing Nagios output and warning/critical threshold behavior are preserved. When the fallback is used, output includes: via WHOIS whois.nic.ar

Installation dependencies:
pip3 install requests nagiosplugin

Example Nagios command:
define command{
command_name check_rdap_expire
command_line /usr/local/bin/check_rdap_expire $ARG1$
}

Recommended service interval remains conservative to avoid excessive RDAP or WHOIS calls.
