Memory usage value in OBAS under Top > Service Director > Virtuozzo Manager > Containers > Container_name > Resources does not match the output of free utility launched on the same Container:

#free -m

             total       used       free     shared    buffers     cached
Mem:          1024        312        711        153          0        123
-/+ buffers/cache:        188        835
Swap:          256         53        202


The container in question is CentOS7-based. In CenOS7 free utility output Cached is split to shared and cached. It is a feature of CentOS 7 free utility.


Memory Usage in OBAS is displayed correctly as well as measured by pvaaagent. To compare it with free output please subtract shared value from -/+ buffers/cache value.
