Analysis of /proc/meminfo

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi , 

  I have the output of /proc/meminfo , but how to 
analyze the individual fields , 
like 

SwapCached:
Active:
ActiveAnon:
ActiveCache:
Inact_dirty:
Inact_laundry:
Inact_clean:
Inact_target:

   Is there any formula by which I can co-relate
the data obtained with the memory usage of the 
processes running ?

   I was unable to get man meminfo 
( like man slabinfo )        

   Looking forward to your response .

Cheers !
