|Title||ucd_mem: count buffered and cached memory as free|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
For memory checks based on the output of a UCD SNMP deamon (check ucd_mem), cached and buffered memory are now counted as free memory. This is consistent with the behaviour of the agent for Linux systems. As a result, the memory usage displayed by checkmk for hosts with this service might decrease if buffered and cashed memory are part of the SNMP information given to checkmk.
