hi all,
have got a ksh script which tries to monitor memory usage of app servers. i do a
ps -0 rss -p <PID>
to get the memory size in KB but when i divide by 1024 to convert to MB i dont know how to round it up ??
thanks in advance.
add 512 to the KB size then divide by 1024....
i get a value of '1274496' from the
ps -o rss -p <pid>
command and when i add 512 to this and divide by 1024 it comes to '1245.125'
is there a function in ksh to round this up so the value returned is '1245' ??
ta.
use expr to add 512 and again to divide by 1024
X=`expr val_in_kilobytes + 512`
MB=`expr $X / 1024`
