Created attachment 225717 [details] Potential Fix vmstat -z currently has: - a missing space in the column header between SIZE and LIMIT - a missing space in the column header between FAIL and SLEEP - inconsistent column spacing between header and values for REQ, FAIL, SLEEP, and XDOMAIN columns The included diff uses the following column sizes: - REQ is 8 bytes (could also be 4 bytes if libxo doesn't mind having values sized differently than 'requests' field name) - SLEEP is 5 bytes (to fit column name) - XDOMAIN is 7 bytes (to fit column name) N.B. Could also make SLEEP and XDOMAIN column sizes be 6 and 8, but then the default length would exceed 80 characters. Current output: # vmstat -z ITEM SIZE LIMIT USED FREE REQ FAILSLEEP XDOMAIN <SNIP> mbuf_packet: 256, 0, 0, 0, 0, 0, 0, 0 mbuf: 256, 4946937, 1, 14, 1, 0, 0, 0 mbuf_cluster: 2048, 772959, 0, 0, 0, 0, 0, 0 mbuf_jumbo_page: 4096, 386479, 0, 0, 0, 0, 0, 0 mbuf_jumbo_9k: 9216, 114512, 0, 0, 0, 0, 0, 0 mbuf_jumbo_16k: 16384, 64413, 0, 0, 0, 0, 0, 0 <SNIP> Output with diff applied: # vmstat -z ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP XDOMAIN <SNIP> mbuf_packet: 256, 0, 0, 0, 0, 0, 0, 0 mbuf: 256,4946937, 1, 14, 1, 0, 0, 0 mbuf_cluster: 2048,772959, 0, 0, 0, 0, 0, 0 mbuf_jumbo_page: 4096,386479, 0, 0, 0, 0, 0, 0 mbuf_jumbo_9k: 9216,114512, 0, 0, 0, 0, 0, 0 mbuf_jumbo_16k: 16384, 64413, 0, 0, 0, 0, 0, 0 <SNIP>
