| (or the container has an invalid configuration). |
| .IP \fBCurrent\fR 4 |
| shows the amount of the resources consumed by the container at a given time. |
| .IP \fBPromised\fR 4 |
| shows the resources soft limit values "promised" for a given container. |
| .IP \fBMax\ \fR 4 |
| shows the resources hard limit values "promised" for a given container. |
| .P |
| If the \fB-v\fR option is specified, the additional information is displayed. |
| .IP \fBLow\ Mem\fR 4 |
| the part of memory residing at lower addresses and directly accessed by the kernel. |
| .IP \fBTotal\ Ram\fR 4 |

| .IP \fBMem+Swap\fR 4 |
| amount of memory available for applications (both RAM and swap space). |
| .IP \fBAlloc\ Mem\fR 4 |
| standard memory allocations made for applications in a container. |
