Administrating Check_Mk Versions - CheckMK Rail2 Mark I Manual

Check_MK rail2 Mark I - Manual 13 / 57

4. Administrating Check_MK versions

It is possible to install several Check_MK versions on the device at the same time. This allows several
instances to be run in different versions and individual instances to be changed to newer or older versions
independently of one another. Meaning you can install a new version for example, and try it out in a test
instance initially in order to then update your productive instance if testing is successful.
To administrate the Check_MK versions, select the item Check_MK versions in the main menu of the
web interface.
The dialogue box that then appears will list all Check_MK versions installed. If a version is not being
used by any instance and is not the last installed version, you have the option to delete it from the
appliance.
Using this dialogue box, you can also upload new Check_MK versions onto the device in order to use
them in new instances or to update existing instances.

To do this, download the desired Check_MK version from our website onto your computer (search for
Check_MK appliance in the Distribution column). Then select the file from your hard drive using the file
selection dialogue and confirm your selection by clicking on Upload & install.
The Check_MK version will now be uploaded onto the device. Depending on the network connection
between your computer and the ESX server, this may take a few minutes. Once uploading is complete,
you will see the new version in the table of installed versions.
