Why switch
Common Checkmk Challenges
Manual Configuration
Checkmk requires every host to be registered explicitly, organized into folders, and assigned the correct check plugins. Automation rules can help, but writing and maintaining those rules demands deep knowledge of the Checkmk rule engine. Teams spend significant time configuring service discovery rules rather than actually monitoring their infrastructure.
On-Premise Overhead
Running Checkmk means provisioning and maintaining a dedicated monitoring server — handling OS updates, disk space management, database backups, and performance tuning. As your infrastructure grows, you also need to plan for distributed monitoring with remote sites, adding even more servers to maintain. Every version upgrade requires careful planning and testing to avoid downtime in your monitoring stack itself.
Legacy Architecture
Built on Nagios foundations, Checkmk inherits a check-interval polling model that struggles with the ephemeral nature of containers and Kubernetes pods. Native container and cloud-native support is limited, often requiring third-party plugins or custom local checks. Modern infrastructure demands real-time streaming metrics, not periodic poll cycles designed for static server fleets.
Plugin Ecosystem Complexity
With hundreds of check plugins available, teams must research, select, and configure the right ones for each host and service. The Agent Bakery simplifies agent deployment but introduces its own configuration layer with baking rules and plugin assignments. Additionally, features like the Agent Bakery and reporting are reserved for the paid editions (Pro, Ultimate, Cloud), creating confusion about what is available in each tier.
What teams say after replacing Checkmk
We deployed Bleemeo across our server infrastructure in only a few hours. Uptime monitoring now alerts us instantly whenever a service encounters an issue.

Advantages
Why Teams Choose Bleemeo
Zero Configuration
No hosts to register into folders, no check plugins to select and configure, no discovery rules to write. Install the Bleemeo agent and monitoring starts automatically within seconds. Unlike Checkmk's manual workflow, you skip the entire WATO/Setup configuration process entirely.
Cloud-Native Architecture
Built for containers, Kubernetes, and modern ephemeral infrastructure from day one — not bolted on through special agents and plugins. Bleemeo natively understands pod lifecycles, container orchestration, and dynamic scaling without the check-interval limitations inherited from Nagios-era designs.
No Server to Maintain
Fully managed SaaS means no monitoring server to provision, update, backup, or scale. Eliminate the overhead of managing Checkmk sites, distributed monitoring setups, and the version upgrade planning that comes with every on-premise installation.
Instant Dashboards
Pre-built dashboards activate automatically for every auto-discovered service, giving you immediate visibility without manual graph creation. Compare that to Checkmk where custom views and dashboard elements need to be configured individually for each host and service group.
Open Source Agent
Glouton, our monitoring agent, is Apache 2.0 licensed and fully open source. You get complete transparency into what data is collected and how, with no vendor lock-in. Audit the code, contribute improvements, or fork it — the choice is yours.
European Data Residency
Metrics and logs are stored in the EU, in the Paris region (France), with GDPR compliance built into the platform. For organizations with strict data sovereignty requirements, Bleemeo provides the regulatory certainty that self-hosted Checkmk offers but without the operational burden of running it yourself.
Features
Feature Parity Where It Matters
Infrastructure Monitoring
Comprehensive CPU, memory, disk, and network metrics with automatic service discovery for over 50 service types. Unlike Checkmk where you select check plugins per host, Bleemeo detects and monitors everything running on your servers without any configuration.
Container & Kubernetes
Native monitoring for Docker containers and Kubernetes clusters, including pods, deployments, services, and node-level metrics. Ephemeral containers are tracked seamlessly as they scale up and down — no manual host registration required for each new pod.
Log Management
Centralized log collection, indexing, and full-text search built into the platform. No separate log server or paid Checkmk edition needed. Correlate logs with metrics on the same timeline for faster root-cause analysis.
Smart Alerting
Threshold alerts with sensible defaults for every discovered service, plus machine-learning anomaly detection that adds context without paging anyone. Multi-channel notifications via email, Slack, PagerDuty, and webhooks — without the complex notification rule chains that Checkmk requires.
Real-time Dashboards
Metrics at 10-second resolution with pre-built dashboards for every discovered service. Includes a custom dashboard builder for tailored views. No manual graph creation or view configuration needed — dashboards appear as soon as services are detected.
Uptime Monitoring
HTTP, TCP, and ICMP availability checks from 7 global probe locations, providing external perspective on service health. Monitor websites, APIs, and network endpoints with detailed response time metrics and SSL certificate expiration tracking.
Migration
Migrating from Checkmk
Most teams run Bleemeo alongside Checkmk for a few weeks before fully switching. The Bleemeo agent runs independently from the Checkmk agent, so there is no conflict during the transition period. Our team is available to help with migration planning and validation at every step.
Deploy Bleemeo Agents
Install the Bleemeo agent on your servers with a single command. The lightweight agent runs alongside the existing Checkmk agent without interference, so your current monitoring remains fully operational during the migration.
wget -qO- 'https://get.bleemeo.com?accountId=...'Verify Auto-Discovery
Within seconds of installation, Bleemeo automatically discovers all running services on each host. Compare the auto-discovered service list with your Checkmk host and service inventory to confirm full coverage. No check plugins to select or configure — everything is detected out of the box.
Review Dashboards
Bleemeo pre-builds dashboards for every discovered service, giving you immediate visibility. Compare these auto-generated dashboards with your existing Checkmk views and custom graphs. Most teams find that Bleemeo provides equivalent or better visibility without any manual dashboard configuration.
Configure Notifications
Set up your preferred notification channels — Slack, PagerDuty, email, or webhooks — in a straightforward interface. Unlike Checkmk's complex notification rules system with its cascading rule evaluation, Bleemeo makes alert routing simple and intuitive to configure in minutes.
Parallel Validation
Run both monitoring systems side by side for one to two weeks. Compare alert accuracy, metric coverage, and dashboard usefulness between the two platforms. This validation period lets your team build confidence in Bleemeo before making the final switch, with no risk to your existing monitoring.
Decommission Checkmk
Once validation is complete, remove the Checkmk agents from your hosts and decommission the Checkmk monitoring server. Reclaim the server infrastructure, storage, and the ongoing administrative time that was spent on updates, backups, and plugin maintenance.
