The Checkmk Appliance
Monitoring made simple. Avoid spending time on the installation and maintenance of the IT required to operate your monitoring system with the Checkmk Appliance.
Physical appliance device types
The checkmk rack1 and checkmk rack4 series are designed for use in data centers.
You can choose from different maintenance levels of your appliance.
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.
Yes. You can directly import the OVA file we provide into your Citrix Xen Host.
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.
Yes, you can enable access of different users via SSH. You can find more details in the chapter Remote access via SSH.
Not generally. For the subscription level the number of monitored services is relevant.
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.
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.
No, the appliance cluster can only have two devices.
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.
No, this is currently not possible.
As of firmware version 1.3.5 is is possible to configure VLANs using the advanced network configuration.
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.
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.
