|Title||mem_linux: switch to mem_used to monitor memory statistics via SNMP|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
Memory statistics from an SNMP data source were monitored by the mem_linux check, which caused it to crash as it is not suitable to evaluate SNMP data (KeyError). With this fix, SNMP data is monitored by the mem_used check.
