Monitoring tool functionality

Checkmk is a comprehensive Solution for IT Monitoring of applications, servers, and networks.
Checkmk is available as a Raw Edition, which is 100% open-source, and as an Enterprise Edition with a newly developed, high performance core, many additional enterprise features and professional support.

checkmk features

State-based monitoring

State-based monitoring
  • Monitor everything using 1700 included 'smart plugins' to collect data from all kinds of hard- and software
  • Quickly identify problems in your IT environment through a differentiated 'state' (OK, WARN, CRIT) of each monitored component or system - drill down with one click
  • Benefit from regularly updated plugins. Your software and hardware contantly changes, so you need plugins which are maintained
  • Use both a powerful agent-based monitoring and an agentless monitoring via HTTP, SNMP or by connecting directly to the APIs of many applications

Log- and event-based monitoring

Log- and event-based monitoring
  • Monitor logs for the analysis of error messages via syslog, SNMP-traps and other arbitrary log files
  • Forward events to trigger scripts or generate notifications
  • Summarize equal entries to one single event (e.g. several failed logons) to stay on top of your events
  • Filter incoming messages to only see important events. No more manual filtering and information overload

Graphing and analytics

Graphing and analytics
  • Analyze time-series metrics over long time horizons with interactive HTML5 graphs
  • Leverage graphic maps and diagrams with live-monitoring data to get a better view on the heath of your IT
  • Compare metrics across multiple graphs at one glance
  • Integrate data from a wide range of data sources and formats for metrics (JSON, XML, SNMP data etc.)
  • Store metrics in disk-space-efficient long-term storage
  • Alternatively use exporters for Graphite / InfluxDB
  • Sample in real-time with measurement intervals of 1 sec

Customizable GUI

Customizable GUI
  • Use a web interface for visualizations and operations
  • Customize dashboards and views to your specific needs
  • Differentiate dashboards and views among users or user groups, e.g. vSphere specific views for VMware admins
  • Bookmark views so that key views are only a click away
  • Customize the side menu e.g. monitoring admins need various statistics while network admins might only need reporting
  • Use the German or English versions of the GUI
  • Adapt the GUI towards your corporate identity within a few clicks

Reporting

Reporting
  • Review the history of states in one click over any desirable timeframe with computation of availability in real time
  • Deaverage availability data. Exclude non-monitored times, change the resolution, ignore short intervals
  • Get notified before you break your SLA contracts by monitoring the compliance of your complex SLAs. Even if the SLA definition contains only working hours
  • Generate PDF reports with your corporate identity containing all the views you build - ad-hoc or automated at regular intervals

Business Intelligence

Business Intelligence
  • Monitor business processes by mapping dependencies of your application into a single view
  • See the availability and performance of complex systems at a glance
  • Aggregate various services and hosts into a single state
  • Review historical states of an aggregation to understand root causes for degraded performances in the past
  • Deliver more reliable services to customers through a completely transparent view, which is easy to understand
  • Configure all possible setups such as HA with two or more nodes, HPC etc. with maximum and unique freedom
  • Simulate worst case scenarios in real time. See the impact of failing components before they become real

Hardware and software inventory

Hardware and software inventory
  • Identify the inventory of all hard- and software installed on devices and systems
  • Monitor changes in hard- and software - use this unique feature to control the access to your hardware and servers and never miss installing a security update again
  • Benefit from integration of regularly updated dynamic parameters such as disk space utilization that are updated via monitoring data
  • Interface to standard off-the-shelf Configuration Management Databases (CMDB) (e.g. i-doit interface from Sep. 2018)

Notifications and alert handler

Notifications and alert handler
  • Notify the responsible team quickly e.g. notify only the storage admins for a failing disk, but not the email admins
  • Notify via email, SMS and 3rd party tools such as Slack, PagerDuty and VictorOps - use your established tools for handling incidents
  • Leverage comprehensive, rule-based notifications to fulfill complex custom requirements regarding time periods, service levels etc.
  • Configure additional alerts or cancel an alert for specific cases. Escalate problems if they are not handled in time
  • Handle alerts centrally also in distributed environments
  • Automatically trigger actions as reaction to detected problems (alert handler) e.g. via scripts

Rule-based configuration, auto-discovery and agent deployment

Rule-based configuration, auto-discovery and agent deployment
  • Use the modern rule-based 1-to-N configuration, which remains intuitive even in complex environments, resulting in lower configuration effort than comparable products
  • Monitor with less effort thanks to automatic detection & configuration of the components. You don't need to configure 'this is a firewall' - all relevant components, their metrics and thresholds will be suggested
  • Centrally automate agent updating ('agent backery')
  • Configure everything in a web interface. No skills in YAML, JSON or other serialization language are needed
  • Feed the monitoring directly via a HTTP-API with already existing information from Configurable Management Databases (CMDB). If you already have automation tools (Ansible, i-doit CMDB etc.) you should use them
  • Use your existing role-based access controls (LDAP, AD) with a fine-grained permission model for users and groups

High-performace core

High-performace core
  • Benefit from Checkmk's own high-performace code 'CMC' (the 'core' is the heart of every monitoring system - it queries the plugins, collects their results, provides states to the GUI etc.)
  • Monitor thousands of services on one single monitoring server. No need to maintain and synchronize several monitoring instances in a single data center
  • Scale across hundreds of sites and millions of devices. Checkmk can support a world-wide distributed setup - hardly any other monitoring system can scale as well
  • Leverage highly efficient monitoring agents with minimal CPU, RAM and storage utilization. No need for DLLs, libraries etc. - runs even on the smallest servers
  • Benefit from a highly secure design incl. the option to encrypt communication between agents and servers
  • Activate changes in fractions of a second, allowing frequent configuration changes, e.g. for container monitoring

Nagios alternative – Nagios compatibility for easy migration

Nagios alternative – Nagios compatibility for easy migration
  • Can use Nagios as the monitoring core (or use Checkmk’s own high performance micro core — CMC)
  • Checkmk Microcore supports existing Nagios checks
  • BUT: no need to live with any of the Nagios deficiencies — the Checkmk Enterprise Edition works 100% stand-alone
