Hi , When I run vmstat on my machine, I get output as procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 3 0 0 0 360408 4540 80292 0 0 26 4 161 249 5 1 9 and according to man vmstat swpd: the amount of virtual memory used (kB). free: the amount of idle memory (kB). buff: the amount of memory used as buffers (kB). Here it shows "swpd" as zero , which is not correct . Also how does the summation of all the three account to 3GB ( 4GB - 1GB[ kernel reserved] ) of Virtual memory available ? By saying , how to find out which specific Kernel areas are free , I meant in the 1 GB Kernel reserved space of the Virtual memory , which structures are free . Regards ! --- "Raghu R.
