openITCOCKPIT

openITCOCKPIT is an open-source monitoring platform for servers, virtual machines, network devices, applications, containers, cloud environments and IoT. Its web frontend and JSON API configure and visualize Nagios, Naemon and Prometheus monitoring, with user permissions; Naemon is the monitoring engine, and the platform is described as compatible with Nagios. Prometheus integration includes exporter management, alert rules and graphical configuration. A cross-platform agent monitors CPU, memory, disks, network interfaces, services, processes, temperature sensors, QEMU and Docker containers on Windows, Linux and macOS. Users can build and share dashboards, and create availability and SLA reports manually or on a schedule in PDF, HTML and CSV formats. Listed integrations include Grafana, Prometheus, PagerDuty, Mattermost, Rocket.Chat, ServiceNow, Slack, i-doit, Checkmk and Nagios Core. The Community Edition is free, while paid subscriptions are also listed. Ubuntu and Debian server support is available in both Community and Enterprise editions; Red Hat/Enterprise Linux support is an Enterprise subscription feature. The platform and agent use TLS/SSL by default, with HTTPS and TLS client authentication listed. The maker is based in Fulda, Germany.

openITCOCKPIT combines infrastructure monitoring with dashboards, scheduled reports and a broad integration list. The free Community Edition is an option, while some server platform support and subscription limits depend on edition.

openITCOCKPIT suits teams monitoring mixed infrastructure and applications that want dashboards, reports and integrations. Organizations requiring Red Hat/Enterprise Linux server support need an Enterprise subscription.

openITCOCKPIT is a self-hosted monitoring platform for infrastructure and applications, best suited to teams overseeing mixed server, network and container environments. Its breadth of monitoring, reporting and integrations is a strong draw; edition-dependent platform support and subscription limits matter when planning an Enterprise deployment.

Overview

A web frontend and JSON API let teams configure and visualize monitoring for Nagios, Naemon and Prometheus, with user permissions. Naemon is the monitoring engine and is described as 100% compatible with Nagios, which makes openITCOCKPIT a practical fit for organizations already using Nagios-style monitoring. Prometheus integration adds exporter management, alert rules and graphical configuration, combining metrics monitoring with conventional service checks.

The platform covers servers, virtual machines, network devices, applications, containers, cloud environments and IoT. That range can support a common monitoring approach across varied infrastructure, but is less persuasive for teams seeking only a narrowly focused monitor.

Key features

The cross-platform agent monitors CPU, memory, disks, network interfaces, services, processes and temperature sensors, along with QEMU and Docker containers on Windows, Linux and macOS. Server auto-discovery, process monitoring and container monitoring help teams cover both hosts and workloads without limiting the system to one infrastructure type.

Users can build and share dashboards, then generate availability and SLA reports manually or on a schedule in PDF, HTML or CSV. Those reporting options suit teams that need to circulate operational or service-level summaries, not just view live monitoring data.

Integrations include Grafana, Prometheus, PagerDuty, Mattermost, Rocket.Chat, ServiceNow, Slack, i-doit, Checkmk and Nagios Core. LDAP/Active Directory, single sign-on, multi-tenancy and role-based access control are included in the editions comparison, giving larger or shared environments relevant access-management options.

The product and agent use TLS/SSL by default; HTTPS and TLS client authentication are also listed. The maker provides an email address for vulnerability reports, and high-impact vulnerabilities are identified for versions before 5.5.2 and 5.4.0. Teams should account for those affected versions when assessing deployments.

Pricing

The Community Edition costs free and provides free infrastructure and application monitoring. It is the clearest starting point for teams that can use its supported server platforms and do not need Enterprise subscription support.

Enterprise subscriptions are priced by year and scale by service count and satellite allowance:

• Bronze: €1 a year; 1,000 services.
• Silver: €3.50 a year; 5,000 services and 2 satellites.
• Gold: €5 a year; 10,000 services and 5 satellites.
• Platin: €10 a year; 30,000 services and 10 satellites.
• Specific: custom pricing for service and satellite needs, with an offer by contact.

The published service and satellite allowances help match a subscription to deployment scale, while the production-system terms constrain how it can be used: Enterprise permits one production master system, and Silver and above allow up to two additional development or test systems. Red Hat/Enterprise Linux support is an Enterprise subscription feature; Community and Enterprise both list Ubuntu/Debian support. Basic subscription support includes up to five requests per contract period, while higher tiers list 25 or 50 cases per year and response times. Teams needing Red Hat support, more support cases or multiple production masters should weigh those terms before choosing a tier.

Platforms

Supported operating systems include Windows, macOS, Debian, Ubuntu, Red Hat Linux, CentOS, SLES and openSUSE. The product is listed for API, iOS, Linux, macOS, self-hosted, web and Windows platforms. The homepage lists an iOS app release dated July 1, 2026. Server support is not uniform across editions: Ubuntu/Debian is listed for Community and Enterprise, while Red Hat/Enterprise Linux requires Enterprise.

Who it's for

openITCOCKPIT is a strong candidate for teams that want self-hosted monitoring across mixed infrastructure, especially those already using Nagios-compatible checks or seeking Prometheus metrics, scheduled reports and broad integrations in one system. It is a weaker fit for organizations that need Red Hat/Enterprise Linux support without an Enterprise subscription, require more than one production master, or want a narrowly scoped monitor rather than a platform spanning many workload types.

Pros and cons

• Pro: Naemon's stated Nagios compatibility and Prometheus integration bring established checks and metrics monitoring together.
• Pro: Dashboards can be shared, and availability and SLA reports can be scheduled in multiple formats, helping teams distribute monitoring results.
• Pro: Agent coverage includes common host metrics, processes, services and QEMU and Docker containers across Windows, Linux and macOS.
• Con: Red Hat/Enterprise Linux support requires Enterprise, so Community is not a fit for every server estate.
• Con: Enterprise subscriptions allow only one production master system; additional development or test systems are permitted only at Silver and above.
• Con: Basic subscription support is capped at five requests per contract period, which may be restrictive for teams needing more assistance.

Alternatives

Infrastructure Monitoring is a useful starting point for comparing the category. Consider Netdata if a free plan with a stated cap of five active connected nodes and one active custom dashboard per room better matches a smaller deployment. Site24x7 Server Monitoring is another freemium option, with a Lite plan at $9 a month billed annually for 2 servers and 5 websites. Netreo is a paid alternative for readers considering a paid monitoring product.

Checkmk may suit teams prioritizing its Community plan, which is forever free and includes 2,000+ pre-built integrations, up to approximately 100 hosts and community support. Icinga is worth considering when an unlimited-host-and-service free edition is the priority. Mackerel offers a free tier with explicit host, metric, retention, rule and dashboard caps, for teams whose needs fit those limits. MetricsHub is an open-source project built around OpenTelemetry. Nagios XI has a free plan capped at 7 nodes or 100 services, whichever comes first, and a paid Standard plan.

Verdict

Choose openITCOCKPIT if your team wants a self-hosted system that combines Nagios-compatible monitoring, Prometheus metrics, broad agent coverage and scheduled reporting. Its strongest advantage is the breadth of infrastructure and workflows it brings together; look elsewhere if Enterprise-only server support, the production-master limit or subscription support terms do not suit your deployment.
