Solution Type Technical Instruction Sure Solution 1001953.1 : Sun Blade[TM] 100 Workstation: sar -v Output for file-sz Format
PreviouslyPublishedAs 202720 Description sar -v doesn't seem to working correctly, given the data collected from kstat. Steps to Follow Since the Solaris 2.6 Operating System, sar -v appears to have a discrepancy. However, sar is working as designed. #kstat -n file_cache | egrep "(buf_avail|buf_total)" buf_avail 620 buf_total 3045 The preceding example of output shows a current buf_total of 3045 and a buf_avail of 620, which means the difference is 2425 file table entries (3045 minus 620). This is the value you see in the sar -v output: #sar -v 1 2 proc-sz ov inod-sz ov file-sz ov lock-sz 13:19:38 243/30000 0 823/128512 0 2425/2425 0 0/0 13:19:39 243/30000 0 823/128512 0 2425/2425 0 0/0 In the example, there are 2425 file table entries. The format of the sar output is a holdover from the early days of static tables, which is why the display is 2425/2425. Originally, the value on the left represented the current number of occupied table slots, and the value on the right represented the maximum number of slots. Because the file table is completely dynamic in nature, both values will always be the same. Note: The Solaris 9 Operating System currently has a bug 4998015 where the file-sz reports 0/0.
