openITCOCKPIT Community Edition, an open source monitoring platform with a Naemon core and a rich web UI for hosts, services, dashboards and maps, with a unique login generated on first boot.
openITCOCKPIT is an open source monitoring platform. It combines the Naemon monitoring core with the Statusengine processing worker and a modern web interface for hosts, services, dashboards, maps, graphs and notifications, so teams can watch their infrastructure and applications and be alerted when something needs attention, all from one console.
cloudimg ships openITCOCKPIT hardened and fully patched, with the full monitoring stack live on first boot and the server already monitoring itself so the dashboards are populated the moment you log in. The admin login, database and every internal secret are generated uniquely on first boot with no default login, and 24/7 support backs the image.
