The monitoring platform for every need

Checkmk is a comprehensive platform for monitoring of applications, servers, and networks on-premises or in the cloud. Thanks to its wide range of features, Checkmk effortlessly monitors both the simplest IT operations and complex IT environments.

Automation

Automate monitoring to save time

  • Add new components with less effort using automatic detection and configuration: Checkmk will recognize it and provide monitoring for all relevant components, along with their metrics and thresholds.
  • Features such as host lifecycle management and auto-registration of hosts help you automate monitoring of dynamic, ephemeral infrastructure: Containers, pods, VMs and more can be added and removed from monitoring automatically.
  • Use modern rule-based 1-to-N configuration, which remains intuitive even in complex environments and results in lower configuration effort than other monitoring solutions.
  • Automate the configuration and operation with the Checkmk REST API.
  • Centrally manage your agents and automate agent updating with the Agent Bakery.
  • Integrate other systems using powerful APIs to automate almost anything imaginable.

Configuration

From zero to monitoring in ten minutes

  • Fast installation from a single integrated package, without the need to separately install and maintain databases and web servers.
  • Available for various Linux platforms, as a Marketplace image for AWS and Azure, as a container image for Docker, and as a virtual or physical appliance.
  • Checkmk's auto-discovery detects your hosts and services for you – effortlessly configure your monitoring with all relevant metrics and thresholds.
  • Integrate your data: Combine the benefits of agent-based monitoring with those of agentless monitoring via HTTP or SNMP – or connect Checkmk to different applications via APIs.
  • Configure everything in a web interface. Fast, easy, and less prone to error.
  • Apply your existing role-based access controls (LDAP, AD) to a fine-grained permission model for user and group actions.

Plug-ins

Ready for powerful hybrid IT monitoring

  • Over 2,000+ maintained plug-ins collect metrics from your systems across heterogeneous IT infrastructures.
  • Checkmk covers not only the most important use cases in the cloud, but also most on-premises systems thanks to its unique plug-in collection – for powerful hybrid IT monitoring.
  • Benefit from actively maintained, regularly updated plug-ins that keep up with your software and hardware changes.
  • There are additional plug-ins shared by our community in the Checkmk Exchange to complement our native plug-ins.

Performance

Scale monitoring with a performance-optimized, distributed architecture

  • Easily monitor thousands of services with one monitoring instance, eliminating the need to maintain and synchronize multiple monitoring instances in a single data center.
  • Scale across hundreds of sites and millions of devices. Build a world-wide distributed monitoring network, achieving a scale that is hard to find in monitoring systems.
  • Leverage highly efficient, self-contained agents with minimal CPU, RAM and storage utilization. They run on even the smallest servers, without the need for DLLs or libraries.

Hybrid Infrastructure Monitoring

Modern monitoring concepts for cloud and on-premises

  • Ingest data with high enough granularity to handle IT architectures of all kinds – traditional environments and container orchestration platforms included.
  • Sample in real-time, with measurement intervals as short as 1 second.
  • Take advantage of special features such as host lifecycle management and auto-registration to automatically map ephemeral hosts and workloads in dynamic cloud and microservice environments in monitoring.
  • Identify problems in your IT with a meaningful status ("OK", "WARN", "CRIT") for each monitored component or system – including deeper analysis with one click.
  • Analyze the state of your IT systems with just a few clicks and view the health of your IT in the right context with Checkmk.
  • Map application dependencies in an overview and monitor complex systems at a glance.
  • Tag your data by hand or auto-discover tags and labels to provide relevant context to help you filter – labels offer full flexibility and tags ensure consistency.
  • Store metrics in disk-space-efficient long-term storage.

Network Flow Monitoring

Get detailed insights into your network

  • In-depth analysis of your network traffic with the integration of network flows into Checkmk via ntop
  • Traffic dashboards for your network
  • View alerts, characterized by duration, severity and alert type
  • Filter flows in many dimensions to analyze your networks
  • Detailed views for your hosts: traffic, packets, ports, peers

Customization

Easily customize or extend to meet your needs

  • Customize or extend the Checkmk source code, written in easy-to-read Python.
  • Rely on us and our broad network of partners to customize Checkmk or its plug-ins.

Visualization

Visualize your data with modern, customizable dashboards

  • Get full visibility on the state of your IT, thanks to Checkmk's modern and customizable dashboards.
  • Out-of-the-box dashboards provide key metrics for AWS and Azure cloud environments, Linux and Windows servers, and Kubernetes clusters.
  • Leverage graphic maps and diagrams with live monitoring data.
  • Analyze time-series metrics over long time horizons with interactive HTML5 graphs.
  • Customize dashboards and views to your specific needs with different dashboard elements to visualize your most important metrics.
  • Compare metrics across multiple graphs at a glance.
  • Custom dashboards and views for users or user groups, e.g. vSphere specific views for VMware admins.
  • Customize the side menu according to your preferences: add snap-ins for your most important monitoring information, as well as links to access to your most relevant functions or reports.
  • Alternatively, visualize your data in Grafana using the Grafana Checkmk datasource plug-in or using Checkmk's Graphite exporter for InfluxDB.

Alerting

Avoid notification overload with smart and granular alerting

  • Notify the responsible team quickly – e.g., notify the storage admins for a failing disk – and escalate problems if they are not handled in time.
  • Automatically send notifications via email, SMS, Slack or MS Teams.
  • Generate tickets automatically for incident handling through integrations with ITSM systems, such as ServiceNow, Jira, PagerDuty, or VictorOps.
  • Configure additional alerts or cancel an alert in specific situations.
  • Handle alerts centrally – even in distributed environments.
  • Use the alert handler to automatically trigger actions upon detection of new problems – e.g., for self-healing.

Log Monitoring

Combine metrics and log data for fast problem identification and root cause analysis

  • Monitor events from sources such as syslog, SNMP traps, Windows event logs, log files, and other applications.
  • Filter and forward events, triggering scripts or generating notifications.
  • Collapse duplicate entries into a single event (e.g. several failed user logins) to prevent operator overload.
  • Filter incoming messages to only show important events – no more manual filtering and information overload.

Advanced Analytics

Predict trends and resource utilization with advanced analytics

  • Analyze historical data to identify trends or forecast future resource consumption.
  • Use sophisticated predictive monitoring algorithms to dynamically adapt thresholds based on historical events.
  • Rely on capacity management that incorporates one-time or seasonal factors in its forecasts.
