Related Articles Monitoring agents Automatic agent updates. From the very beginning, monitoring Windows servers has been one of the most important tasks performed by Checkmk. As for all other server operating systems, Checkmk therefore also delivers its own agent for Windows. In the Checkmk version 2. The Agent Controller is upstream of the agent program, queries the agent program and communicates with the Checkmk server in its place. To do this, it registers with the Agent Receiver , which is also a new process running on the Checkmk server.
So, on the one hand, the new Windows Agent is taking over functions from the agent program, and thus its advantages. The registered, encrypted and compressed pull mode with the Agent Controller is available from version 2.
The Agent Controller is only executable on certain newer Windows versions. You can see which versions are supported in the table below. However, the agent also masters a so-called legacy mode to support older Windows versions. In this mode the new agent works like the old one, i. For the legacy mode some special features have to be considered, which are summarized in the installation chapter.
For compatibility reasons, the agent supports only the current versions of the Microsoft Windows NT product line edition. The following table lists them explicitly. In the Version column you will find the beginning of the version number, which can be displayed on the Windows system with the commands ver and systeminfo.
Important : Editions not listed in the table are not officially supported. This also includes Windows Embedded , for example. The installation, registration, and setup of the agent can be accomplished in just a few steps, because the agent does not need any additional libraries for its function, for example. In addition, the agent is shipped with a basic configuration that is sufficient for most use cases. The Checkmk agent consists of the agent program and the Agent Controller, which communicates with the Agent Receiver on the Checkmk server.
See the general article on monitoring agents for details on the common architecture of Linux agent and Windows agent.
This chapter is about the Windows specific implementation. The program is started as a Windows service under the local system account Local System account. It collects data about the local system when called and makes it available to the Agent Controller. The agent program is minimalistic, secure, easily extensible and comprehensive, having access to important data that is not accessible via WMI or SNMP. See the article on monitoring with SNMP for more on this topic.
In addition, the agent program is as transparent as a file delivered as executable can be, because you have access to the source code at any time and thus insight into the functionality and can in principle also compile the agent yourself. The Agent Controller cmk-agent-ctl. It runs as a background process under the local system account of Windows.
Simple installation of a standard agent with manual configuration via configuration files. The package from the agent bakery is installed for the first time by hand or by script and automatically updated from then on.
The installation can be completely automated here using the MSI format. Before installation, you need to get the package and bring it to the host for example with scp or WinSCP on which the agent will run. For example, the supplied MSI package for the Windows agent can be fetched using the following curl command. In newer Windows versions curl is already included, in older versions you will first have to install the curl command environment separately via curl for Windows.
Use the Next buttons to scroll through the pages of the wizard. Then the Setup wizard presents you with the following page:. The choices on this page are relevant to you only if a Windows agent is already installed on the host and it is older than version 1.
In version 1. If you are updating or migrating from a Windows agent before version 1. There you will learn which of the provided options you should select in this particular update case. In all other cases, we recommend selecting the Clean installation.
Confirm the start of the installation and then allow the installation program to make changes in the User Account Control dialog. When finished, you can exit the Setup wizard. After the installation, the agent will immediately start as a Windows service and be ready to monitor the system. Via the command line, Windows provides administrators with msiexec the possibility to install MSI packages automatically without user interaction.
An automated installation can then look like this, for example:. So this method is great for automatically rolling out the agent to many hosts. You can also use this method to select the three options that were offered to you during the manual installation in the Setup wizard.
For each option, there is an identifier that you can use for the installation command:. Remove Legacy Windows Agent pre 1. Migrate from Legacy Windows Agent pre 1. To explicitly disable an option, you must add two more quotation marks following the equal sign:. For a detailed description of this, see the general article on agents. The installation of the baked MSI package is then done again exactly as described above.
If you use the Agent Bakery, you can set up automatic updates of the agent. These are described in their own article. You do not need to customize the program-specific files. The host-specific files are used to store plug-ins, log and configuration files and to configure the behavior of the agent.
If an option has been set in multiple files, then the last file read in determines the content of this option. As you may have already recognized from the file extension of the configuration files, YAML is used as the file format.
After installing the agent including the Agent Controller, the next step is the registration , which sets up TLS encryption so that the encrypted agent output can be decrypted by the Checkmk server and displayed in monitoring.
There is a special feature when the agent was installed with the Agent Controller for the first time. Then the agent switches to the unencrypted legacy pull mode so that the Checkmk server is not cut off from the monitoring data and can continue to display it. This applies to a new installation as well as to an update of an agent of version 2. After registration, only encrypted pull mode is used for communication.
The legacy pull mode is switched off and will remain so. However, it can be switched on again by command if necessary. The case is different if the agent is installed on very old Windows systems.
The installation of the agent may be successful. However, if the Agent Controller cannot be started due to API incompatibilities, the unencrypted transfer is resorted to. Without Agent Controller, registration is not possible and the only communication path remains the legacy mode.
In legacy mode, only the sections in the Registration chapter are relevant for adding the host to the Setup and then to the monitoring.
In the chapter Testing and troubleshooting you must omit the test for calling the Agent Controller, because it is not available in legacy mode. Since there is also no TLS encryption without Agent Controller, you have to use other methods of encryption if required. Note: In the Checkmk Agent installation auditing rule set you will find various settings to check the state of the agent and make it visible in monitoring.
Immediately after the installation of the new agent also as an update of an agent of version 2. An exclusively encrypted data transmission is only active after a trust relationship has been established. This chapter shows how to do this. For this purpose, a good choice is the automation user , which is automatically created with every Checkmk installation and whose password you can randomly generate. Note: Since there is no Agent Controller, and thus no registry and TLS encryption, on very old Windows systems , you have to use other methods of encryption if required.
In this case we recommend using the built-in symmetric encryption with the rule Encryption Linux, Windows or to set up an SSH tunnel. A host must exist in the configuration environment before it can be registered.
The registration is done using the Agent Controller cmk-agent-ctl , which provides a command interface for configuring the connections. You can use the cmk-agent-ctl help command to display help on the options.
Now go to the host that is to be registered. Here you have to make a request to the Checkmk site with administrator rights:. The host name following the –hostname option must be exactly the same as it was when it was created in the Setup. The –server and –site options specify the name of the Checkmk server and the site. The server name may also be the IP address, the site name here mysite corresponds to the one you see in the URL path of the web interface.
The options are completed by the name and password for the automation user. If you omit the –password option, the password will be requested interactively. If the specified values were correct, you will be asked to confirm the identity of the Checkmk site to which you want to connect.
We have shortened the server certificate to be confirmed for clarity:. If no error message is displayed, the encrypted connection has been established. All data will be transmitted in compressed form via this connection.
The cmk-agent-ctl status command now shows exactly one trust relationship with the Checkmk server:. Note: There can only ever be one trust relationship between host and site.
