| mem.bits |

| mem.resident |
20 |
number of megabytes resident. It is typical over time, on a dedicated database server, for this number to approach the amount of physical ram on the box. |
| mem.virtual |
2502 |
virtual megabytes for the mongod process. Generally virtual should be a little larger than mapped, but if virtual is many gigabytes larger, that could indicate a memory leak - with journalling, virtual is twice mapped |

true |
Whether or not this machine supports extended memory info. If this is false, other values in 'mem' may not be present |
