Based on 4fcd56bf582ee2ef5b205625ca3d1bfed90364e9 Mon Sep 17 00:00:00 2001 From: Jaromir Capik Date: Tue, 4 Feb 2014 19:10:42 +0100 Subject: [PATCH] vmstat: Support for timestamps with '-t' & fix for '-wd' From now the vmstat can append a timestamp to each line in the VMSTAT and DISKSTAT mode. You can achieve that with the '-t' switch. The '-w' switch now works in the DISKSTAT mode too. --- vmstat.8 | 3 + vmstat.c | 197 +++++++++++++++++++++++++++++++++++++++++++++++++++----------- 2 files changed, 167 insertions(+), 33 deletions(-) diff --git vmstat.8 vmstat.8 index ef6cbe9..420d9f3 100644 --- vmstat.8 +++ vmstat.8 @@ -74,6 +74,9 @@ or 1048576 bytes.
