Virtual appliance

The virtual appliance Check_MK virt1 is available in formats that can be read by all common virtualization platforms. Check_MK 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.

Physical Appliance

The Check_MK 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 Check_MK 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 on site.

Physical appliance device types

There are several models of the physical appliance available for use in different environments.
The Check_MK rail2 is designed for industrial use. It is optimal in environments where space and power consumption matter. It is fit for mounting on TS 35 DIN rails.
The Check_MK rack1 and Check_MK rack4 use the classical 19-inch format and come with redundant power supplies. They are designed for use in datacenters.

1 Hardware maintenance level dependent on service contract.
2 Update provisioning as along as a Check_MK subscription is active. Provisioned updates can be installed by the user or by us. The latter will be charged.
3 Requires support contract and active Check_MK-subscription.
4 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 Check_MK rack1, rack4 or a dedicated server.
5 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.
6 The usage of the Check_MK Appliances requires a subscription of the Check_MK Monitoring System for at least one year. The services that you monitor with your appliances are charged to your normal subscription. Within the subscription you have access to updates of the appliance firmware and the Check_MK Monitoring System.
7 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
8 Pricing includes 8GB Swissbit Industrial SD Card. 16GB can be purchased as add-on
