They differ on breadth, pricing, and what an operator has to configure. Last verified: 2026-06-25. Glassmkr is not affiliated with Checkmk GmbH. > Checkmk is a long-established enterprise monitoring platform (Munich-based, Nagios lineage). Editions as of 2026-03-17 are Community (free, self-hosted, ~100 hosts) [1](#fn1), Pro (from EUR 190/month annual), Ultimate (from EUR 275/month annual), Cloud SaaS (EUR 240/month), and Ultimate with Multi-Tenancy [3](#fn3) [4](#fn4). Pricing is service-based (~30 services per host typical) [1](#fn1). Glassmkr is opinionated bare-metal monitoring at $3/node/month with 3 free nodes [G](#fn-glassmkr). 65 alert rules ship enabled and tuned. Checkmk wins on breadth (2000+ official plugins [8](#fn8)), distributed monitoring across regions, and enterprise features (RBAC, audit logs, LDAP/SAML). Glassmkr wins on time-to-value for focused bare-metal monitoring without the operational footprint. ## What’s the same Both monitor Linux servers, route alerts, and have free tiers. Both cover SMART, IPMI, and common RAID controllers on bare metal. Both have multi-channel notifications. ## What’s different | Dimension | Checkmk | Glassmkr | | --- | --- | --- | | Vendor | Checkmk GmbH (Munich, DE) | Glassmkr (Prague-based EU sole-trader) | | Editions (current) | Community / Pro / Ultimate / Cloud / Ultimate w/ Multi-Tenancy [3](#fn3) | One product, two tiers (Free, Pro) | | Community license | Free / open-source (GPL via Nagios lineage) [1](#fn1) | Agent MIT; dashboard proprietary (SaaS) | | Pro pricing | From EUR 190/month annual; ~EUR 1.90/host equivalent at 100 services [1](#fn1) | $3/node/month after 3 free [G](#fn-glassmkr) | | Cloud SaaS pricing | EUR 240/month base; ~EUR 7.20/host at 30 services [1](#fn1) | $3/node/month (same product, no separate SaaS tier) | | Pricing unit | Service-based (~30 services per host typical) [1](#fn1) | Per node | | Plugin / integration count | 2000+ [8](#fn8) | Bare-metal focused; ~10 integration surfaces | | Auto-discovery | Yes, services and network devices [5](#fn5) | Agent reports what it finds on the host | | Distributed monitoring | Central + hundreds of remote sites [5](#fn5) | Single dashboard; all agents report to it | | RBAC / audit / LDAP / SAML | RBAC in all editions; LDAP/AD from Pro; SAML SSO Ultimate/Cloud only [9](#fn9) | Not currently surfaced as a feature | | SMART / IPMI | Built-in plugins (`smart`, `freeipmi`) [6](#fn6) [7](#fn7) | Built-in via Crucible agent | | Opinionated bare-metal rules | No "best-practice rule pack"; thresholds operator-tuned | 65 rules tuned out of the box | ### Bare-metal coverage Checkmk Community covers SMART (`smart` plugin via smartctl) and IPMI (via the `freeipmi`/`ipmi-sensors` integration), plus vendor-specific RAID controllers, PSU, and memory plugins [6](#fn6) [7](#fn7). The coverage is broad but unopinionated: defaults are generic, and operators tune thresholds and rules to fit their fleet. ECC and ZFS specifics typically combine the generic Linux agent with hardware-vendor plugins or Checkmk Exchange contributions. Glassmkr ships 65 rules with pre-tuned thresholds and per-alert remediation guidance built into the dashboard. Coverage is narrower than Checkmk’s 2000+ plugins but tuned for "this is genuinely a problem worth waking someone up about." ### Operational profile Checkmk Community installs on Linux (RHEL/SLES/Debian/Ubuntu), as a virtual appliance, or in Docker. Setup is six steps per the docs [2](#fn2); an experienced operator can complete the install in under an hour. Real-world deployments add agent rollout, host inventory, rule tuning, and notification configuration on top. The SaaS Cloud edition removes server install but still requires agent deployment and rule configuration. Glassmkr removes all of the dashboard-side setup (no install) and the rule-authoring work (65 rules ship enabled). Agent install is one bash command. ## When Checkmk is the right choice ### You run a heterogeneous enterprise fleet. Switches, storage arrays, hypervisors, network devices, application servers, databases. 2000+ plugins covers the vendor matrix Glassmkr doesn’t reach. ### You need distributed monitoring across regions. Checkmk supports central + hundreds of remote sites; basic distributed monitoring (Livestatus) is available in all editions including the free Raw edition, with the optimized Livestatus proxy commercial-only [5](#fn5). Glassmkr has a single dashboard model. ### You have RBAC / audit / SSO requirements. Compliance contexts that require role-based access, audit trails, LDAP/SAML integration. Checkmk ships role-based access in every edition, LDAP/AD from Pro up, and SAML SSO in the Ultimate and Cloud editions [9](#fn9). Glassmkr doesn’t currently. ### You prefer broad coverage over opinionated defaults. If your monitoring philosophy is "monitor everything and tune from there," Checkmk’s breadth fits. Glassmkr’s philosophy is the opposite. ## When Glassmkr is the right choice ### You want focused bare-metal monitoring without the operational footprint. No Checkmk site to install, configure, version-upgrade, and TLS-secure. One agent, one hosted dashboard. ### You want SaaS-style per-node pricing. $3/node is flat and predictable. Checkmk’s service-based pricing is more complex (and reasonable for what it covers); Glassmkr is the simpler shape if your needs fit it. ### You don’t need 2000+ plugins. If your fleet is Linux bare-metal servers (not network devices, storage arrays, vSphere clusters), the breadth advantage doesn’t apply. ### You want a modern UI without Nagios-era ergonomics. Checkmk has modernized significantly but its lineage is visible. Glassmkr was built recently with no legacy. See it on real infrastructure.

One server is one node. **Checkmk Services → individual alert-rule subjects.** A Checkmk host’s ~30 services map to multiple Glassmkr alert rules (each with its own threshold). The mapping is many-to-many; not 1:1. **Checkmk Views / Dashboards → Glassmkr server detail pages.** Per-server, with metrics and alert state. **Checkmk Notifications → Glassmkr notification channels.** Reconfigure routing once. **Checkmk Host Groups → Glassmkr node tags (loosely).** The grouping model differs; Glassmkr is per-node with tag-based labels rather than Checkmk’s hierarchical groups. The honest trade-off: you give up integration breadth, distributed monitoring across sites, and enterprise features (RBAC, audit, LDAP/SAML). You gain a simpler operational footprint and opinionated bare-metal defaults. > Last verified: 2026-06-25. Sources cited inline. Glassmkr is not affiliated with Checkmk GmbH.
