The amount of memory reserved for the appliance services has been increased to ensure problemfree cluster operation. The reservation limits the amount available for checkmk sites on an appliance. In case of a virtual appliance please make sure you assign sufficient memory (at least 4GB) to the virtual machine.
Details:
Apache2 und webconfd are required for user interaction through the webinterface. corosync and pacemaker are required for cluster operation.
The memory reserved for these services has been increased based on current measurements from life environments to the following values: * Solo operation mode: 1152MB * Cluster operation mode: 1888MB
The reservation is made in order to guarantee the operation of the appliance and support the survival of the required servies even in situations where free memory might run short and the Linux kernel OOM killer is activated.
The metric for system usage has been removed from the check User_Memory. Please use the standard memory check for this.
