机器开机和关机时写在eventlog中的第一条日志和最后一条日志分别为:6005和6006。
timecreated id leveldisplayname message ----------- -- ---------------- ------- 8/18/2014 9:23:04 am 6005 information the event log service was started. 8/15/2014 7:03:48 pm 6006 information the event log service was stopped.
所以根据上面的信息很容易得出机器的开机,关机,在线时间,代码为:
function get-computeruptimehistory { $q=' <querylist> <query id="0" path="system"> <select path="system">*[system[(eventid=6005 or eventid=6006)]]</select> </query> </querylist>' $events = get-winevent -filterxml $q $i=-1 while ( $i+1 -lt $events.length ) { if($i -eq -1) { [pscustomobject]@{ starttime = $events[0].timecreated; stoptime = $null ; uptime = [datetime]::now - $events[0].timecreated } } else{ [pscustomobject]@{ starttime = $events[$i+1].timecreated; stoptime = $events[$i].timecreated ; uptime = $events[$i].timecreated - $events[$i+1].timecreated } } $i += 2 } }
输出为:
ps> get-computeruptimehistory | ft -autosize starttime stoptime uptime --------- -------- ------ 8/18/2014 9:23:04 am 2.05:00:22.5891685 8/13/2014 9:30:42 am 8/15/2014 7:03:48 pm 2.09:33:06 7/22/2014 12:16:09 pm 8/13/2014 9:29:09 am 21.21:13:00 7/22/2014 9:23:08 am 7/22/2014 11:26:08 am 02:03:00 7/17/2014 11:08:57 am 7/21/2014 6:20:28 pm 4.07:11:31 7/14/2014 9:35:11 am 7/17/2014 11:07:25 am 3.01:32:14 7/10/2014 3:01:53 pm 7/14/2014 9:21:48 am 3.18:19:55 7/8/2014 5:04:02 pm 7/10/2014 2:58:36 pm 1.21:54:34 6/30/2014 9:17:28 am 7/8/2014 5:01:24 pm 8.07:43:56 6/29/2014 10:24:50 am 6/29/2014 6:04:09 pm 07:39:19 6/20/2014 9:33:08 am 6/27/2014 6:18:34 pm 7.08:45:26 6/16/2014 3:05:45 pm 6/20/2014 9:31:16 am 3.18:25:31 6/12/2014 9:40:05 am 6/16/2014 3:04:02 pm 4.05:23:57 6/6/2014 2:52:11 pm 6/12/2014 9:37:46 am 5.18:45:35 6/5/2014 10:55:20 am 6/6/2014 2:51:09 pm 1.03:55:49 6/5/2014 9:19:38 am 6/5/2014 10:54:04 am 01:34:26 6/3/2014 1:33:24 pm 6/4/2014 7:58:58 pm 1.06:25:34 5/30/2014 10:07:06 am 6/3/2014 1:31:24 pm 4.03:24:18 5/29/2014 5:30:33 pm 5/30/2014 9:41:41 am 16:11:08 5/29/2014 5:28:57 pm 5/29/2014 5:29:43 pm 00:00:46 5/29/2014 2:52:58 pm 5/29/2014 5:26:57 pm 02:33:59 5/29/2014 2:50:31 pm 5/29/2014 2:51:06 pm 00:00:35 5/27/2014 11:54:43 am 5/29/2014 2:47:29 pm 2.02:52:46 5/23/2014 5:31:18 pm 5/26/2014 9:16:33 am 2.15:45:15 5/22/2014 6:00:29 pm 5/23/2014 9:16:45 am 15:16:16 5/21/2014 4:38:22 pm 5/21/2014 4:40:07 pm 00:01:45 5/21/2014 9:43:59 am 5/21/2014 4:36:34 pm 06:52:35 5/19/2014 11:27:28 am 5/21/2014 9:42:32 am 1.22:15:04 5/19/2014 9:25:56 am 5/19/2014 9:27:00 am 00:01:04 5/15/2014 9:23:15 am 5/15/2014 9:24:16 am 00:01:01 5/15/2014 11:18:45 am 5/15/2014 11:19:49 am 00:01:04
