Nagios has experimented with promotional keys for its Core Services Platform (CSP) bundle. For a time, a promotional license key "CSP50" provided a personal version of a 50‑node XI with Enterprise features. However, these promotional keys appear to have limited lifespans. As one Nagios support team member noted, "The CSP50 license is entering an expired state". Users of newer builds (R2 or later) were directed to a "CSP10" license with more limited host capacity.
