The new check {mem.linux} replaces {mem.used} and {mem.vmalloc} for Linux hosts. It takes core of almost every aspect of the Linux memory management, such as page tables, shared memory, overcommitting, disk writeback areas and much more. It outputs lots of performance data. Depending on the kernel version and of which memory areas are present you will see up to ten predefined PNP graphs for a single host!

Please note that this is an incompatible change since the new check's performance data is not compatible with that one from the superseeded checks. The new check will be selected as soon as you redo the service discovery for your Linux hosts.
