Check_MK - Nagios at a new level

Check_MK - Screenshots:





Check_MK and the Check_MK Monitoring System

The Check_MK Project

Check_MK is a comprehensive addon for the famous Open Source monitoring software Nagios. You can integrate Check_MK into your existing Nagios/Icinga environment.



Check_MK simplifies the configuration and makes monitoring with Nagios much more efficient.



Check_MK is 100% Open Source and available under the terms of the GNU GPL.

The Check_MK Monitoring System

The Check_MK Monitoring System is a complete IT monitoring solution. It's based on Check_MK, Nagios and many other modules. It is optimized for enterprise usage.



You get access to the Check_MK Monitoring System via a subscription, optionally including professional support. Also available are real and virtual Appliances.
There are three different ways of how to use Check_MK:
  1. Manual installation: you integrate Check_MK into an existing Nagios- or Icinga environment. This is done with a setup script contained in the source codes of Check_MK. You are responsible for the correct integration of all components.
  2. Utilisation of the RPM/DEB-packages of the Check_MK Monitoring Systems which we make available under asubscription.
  3. You use the The Check_MK Appliance - either in its 19-inch rack version (Check_MK rack1), with DIN rail mount (Check_MK rail1) or as a virtual appliance (Check_MK virt1).

Screenshots - The Check_MK Status GUI

Login



The login dialog, new sites are created with the useromdadmin and the password omd.
The Main Dashboard



Dashboards combine several elements into one view. The dynamic layout algorithm automatically adapts the dashbaord to all possible screen sizes and formats.
Current Problems



The default problems view displays all or just the unhandled problems, grouped by their state. Views can be customized.
Service Details



All details about one service
Flexible Filtering



Views offer flexible filtering mechanism for hosts and services
List of Services



This screenshot shows the list of services of a host. Performance values are graphically visualized.
Example: Search for CPU serives



A simple search for CPU in the Quicksearch snapin shows all relevant CPU services. This allows an easy comparison of the current performance of verious hosts.
Network Topology



By use of the integrated NagVis, network dependencies are visualized automatically.
Multicolumn Views



Views can make use of large screens by displaying multiple columns of data instead of just one.
Executing Commands



All Monitoring commands can be issued not only on a single object, but also on several at once.
Customizable Views



All views can be customized. You can define your own filters, columns, grouping, layout and other aspects.
Business Intelligence



The BI Module allows you to compute the state of an application or a business process by combining thestate of hosts and services, while taking redundancies into account.
Performance Historization



All performance values are kept for several years. This allows not only a conveniant error diagnosis but also capacity planning.
Networking Performance



A detailed statistics of all packets, bytes and errors are stored separately for each switch port and each network device of a server
Alert statistics



This builtin view shows report of the most frequent problems among all hosts and services. The time frame for this is selectable by the user.
Customizable Sidebar



Each user can have his or her individual sidebar. Many snapins are available.
History of Events



This example shows the global history of events.
Availability Monitoring



From the historic states you can compute an availability for each host, service or BI aggregation.
Timeline



This shows the time line of a services with respect to its historic states and availability.
NagVis Integration



The graphing tool NagVis is seamlessly integrated into the Check_MK GUI. A dedicated Snapin gives quick access to all maps.
Event Console



The Event Console processes messages from syslog, SNMP traps, Windows event logs or text files. Via flexible rules you can specify how to handle each event.
Monitoring of VMWare ESX



Check_MK has its own plugin for monitoring VMWare ESX via vSphere. You can either connect to the host systems or to the vCenter.

Screenshots - The Configuration GUI (WATO)

WATO - Main Menu



WATO is the Web Administration Tool for Check_MK. The complete monitoring system can be configured via the Web. For experienced users an administration via config files is also possible.
Hosts and Folders



The monitored hosts are organized in Folders. Attributes can be configured on a folder-level and inherited to the hosts.
Details of one Host



Each attribute can either be set explicitely or is inherited by one of its parents folders. That way most stettings are chosen correctly just be adding a host to the correct folder.
Global settings



This screens shows some of the global settings.
Rule based configuration



The configuration of host- and service-parameters is based on rules like "Use a warning level of 90% on all filesystems on productive Linux systems that begin with/oracle."
Check parameters



The check plugins that come with Check_MK can be configured with full GUI support. Every parameter is validated and a help text is available.
User, Contactgroups aand Roles



All users and permissions are configured via WATO.
LDAP-Integration



Check_MK allows to connect to an existing LDAP user database (like Active Directory).
Roles and Permissions



Via configurable roles you can specify which user should be able to perform which actions.
Timeperiods



Custom timeperiod definitions allow to restrict checks or notifications to certain times.
BI-Module



In the current version also the BI aggregations can be configured via WATO.
Logfile patterns



The pattern editor for the intergrated logfile monitoring
Distributed Setup



Check_MK allows to build one centrally administered large monitoring system by connecting several remote Check_MK instances. No monitoring data needs to be centralized. This saves network bandwidth and scales well.
