Question RAM Usage Discrepancy - Health Monitor vs Server Information

[pointblank]

Hi Everyone,

Not sure If I am reading this correctly but when I check my RAM usage using Health Monitor, I see:
12.3% usage and 480 MB used of out 3.8 GB.

But when I go check the RAM usage under Server Information, I see:
22% usage and 3.0 GB used out of 3.8 GB

Which number should I rely on?

both are correct,

The second includes buffers and cache.
There are lots of memory types in use. If you really want the details, you need to go via the command line.

"cat /proc/meminfo" or "free" are both memory info commands

example output of "free" command

             total       used       free     shared    buffers     cached
Mem:      49550936   48891024     659912     328240    6405796   33922588

Swap:     10485756          0   10485756

example output of cat /proc/meminfo command
