Checkmk virt1 is a virtual appliance available in formats that can be read by all common virtualization platforms. Checkmk virt1 is delivered fully pre-installed as an image with operating system and is ready to operate. It can be set-up using dialogues and can be configured using its own web UI. You do not require any Linux know-how to do this.
A highlight: Its firmware and operating system are identical to those of the hardware appliances and it is thus 100% compatible. This allows a simple management of all appliance types also in a mixed environment, for example, across multiple sites.
|Number of Hosts1||1,500|
|Number of Services1||30,000|
|Data-Volume2||4.0 - 100.0 GB|
|Price3||Starting from €300 per year|
Our physical appliance comes as a ready-to-use device and is operational after only a few minutes. A web UI is available to configure the operating system. The innovative storage concept of the appliance enables a quick hardware replacement. All settings, user data, and installed Checkmk versions are stored in the external storage (RAID 1 or SD card) and can thus be easily transferred from one appliance to another. This enables easy hardware maintenance without the requirement to have a linux expert in site.
Physical appliance device types
The checkmk rack1 and checkmk rack4 use the classical 19-inch format and come with redundant power supplies. They are designed for use in datacenters.

In case of hardware faults, please contact us via email to firstname.lastname@example.org or by phone +49 89 9982 097-20.
In case of software faults, independent of whether they related to the firmware or the Checkmk Monitoring software, please contact us by email to your company's specific support address. We will provide support based on the conditions of your purchased support agreement.
1 This is only a recommendation. The appliance is not limited in the number of hosts or services which can be monitored with this device. The number of hosts depends on a powerful virtualization environment and is only valid if enough CPU, memory and disk IO bandwidth is available. In larger environments we suggest using the Checkmk rack1, rack4 or a dedicated server.
2 The data volume of the virtual appliance has been created with a dynamic size of up to 100 GB. This is usually enough for about 30,000 monitored services.
3 The usage of the Checkmk Appliances requires a subscription of the Checkmk Monitoring System for at least one year. The services that you monitor with your appliances are charged to your normal subscription. You have access to the appliance firmware updates as long as the appliance is under warranty or maintenance contract.
4 This is only a recommendation. The precise number of monitored hosts and services is, for example, dependent on the type of device and the check frequency. The appliance is not limited per se in the number of hosts or services which it can monitor.
5 Outside of Germany additional shipment cost will occur and outside the EU prices can differ.
6 Shipment times are valid for Germany and begin with the ending of the response time. The service hours are: Mon-Fri, 7am-6pm CET, with the exception of bank holidays. Upon request, we are happy to provide you with potential differences for you preferred location.
7 Upon request, we are happy to provide you with the pricing for your preferred location.
How can I clear the mail queue?
It might happen that there are several mails in the local queue on the appliance - mails which have been created due to a misconfiguration. In this case it might be useful to be able to clear the queue.
The mail queue can be deleted via the page Manage email in the Web Configuration. On this page you can delete the emails one by one if you like.
Additionally, you can delete the emails using SSH. You need to enable root access via SSH and to connect to the device as root user. After login you can execute the mailq command to take a look at the mail queue, and rm /var/spool/nullmailer/queue/* to delete all mails from the queue.
Can the checkmk virt1 be used with Citrix Xen?
Yes. You can directly import the OVA file we provide into your Citrix Xen Host.
Can the checkmk virt1 be used with Microsoft Hyper-V?
It is possible, but not officially supported. However, it is possible to convert the OVA file we provide to a format which can be imported to your Hyper-V server.
Is it possible to access the appliance via SSH?
Yes, you can enable access of different users via SSH. You can find more details in the chapter Remote access via SSH.
Is a dedicated subscription needed for each device?
Not generally. For the subscription level the number of monitored services is relevant.
Where can I find the documentation for the appliance?
When you buy a device you will receive a printed manual with your device. The up-to-date documentation can also be found on our website in the User Manual.
Is the cluster active/passive or is it active/active?
A cluster of two devices is always an active/passive cluster. The active device is holding all of the resources, and the passive device is ready to take over the resources, if the active device fails.
Is it possible to create clusters of more than two devices?
No, the appliance cluster can only have two devices.
Is it possible to extend the RAM of the checkmk rack?
The checkmk rack1 Mark IV and checkmk rack1 Mark V have 4 DIMM sockets for DDR3 RAM. Both can handle up to 32GB ECC unbuffered DDR3-1600MHz RAM.
The checkmk rack4 Mark II and rack4 Mark III have 16 DIMM sockets for DDR4 modules. The device can work with up to 1TB DDR4-2400 ECC RAM.
So technically it is possible to extend the RAM. You are allowed to exchange the built-in memory modules to extend the memory of the devices on your own.
Please ensure that you know what you are doing. We are not responsible for any damage done to the hardware. Please also note that using memory that is not authorized by the vendor may forfeit your warranty.
Is it possible to configure the IP address via DHCP?
No, this is currently not possible.
Can the appliance support VLANs (IEEE 802.1q)?
As of firmware version 1.3.5 is is possible to configure VLANs using the advanced network configuration.
Is it possible to extend the HDDs of the checkmk rack?
The checkmk rack1 Mark I has two 2.5" front mount slots.
The checkmk rack1 Mark II has 4x 3.5" front mount slots. With the current firmware you can use the first two mount slots.
The checkmk rack4 Mark I has 4x 3.5" front mount slots. With the current firmware you can use the first two mount slots.
You can use custom SSDs instead of the delivered ones. The drives are always configured as RAID-1.
Can the checkmk virt1 be used with KVM?
Yes. You basically need to download the OVA file we provide, unpack it and convert the shipped virtual HDDs from the VMDK format to, e.g., the QCOW2 format. You can then copy these virtual hard disk files to the paths where your VM images are stored. Finally, create a VM with the parameters of your choice and use the just converted QCOW2 disk images as harddisks.
You may want to take a look at the "virt1.ovf" file to see which parameters to use for the VM you create in the next steps. Some things are mandatory:
- You need to give the VM at least 2 GB of memory.
- You need to use the BOTH of the hard disks you just converted.
- Use virtio for the disks for best performance.
