终端开发文档参考

终端如VT100,VT50，VT220等终端，其相关的文档都汇聚在这个网站上。

http://man.he.net/man4/console_codes【Linux Console Codes】【Linux下的console文档，是vt102的子集】
Vt102是vt100家族的第二代指令，在原有vt100基础上增加了行插入行滚动的几个指令。

sed提取json中有用字符串 


mytest='"summary":{"day":{"burstTotal":0,"dropTotal":135764,"flowTotal":69449},"input":{"spanCount":900,"spanInterval":10},"spanNow":{"burstTotal":0,"dropTotal":1,"flowTotal":4,"now":1548691410},"spans"'
echo $mytest| sed 's/\(.*\)"day":{"burstTotal":\([[:alnum:]]*\),"dropTotal":\([[:alnum:]]*\),"flowTotal":\([[:alnum:]]*\).*/\4/' && echo ":flow121"

解决WIN10显示文字模糊

主要原因是系统允许应的缩放比例生效，按如下修改可解决。
1.桌面右键->显示设置->高级缩放设置如下图：

2.在高级缩放设置中，开启“允许window尝试修复应用，使其不糊模”，及在自定义缩放比例上，填上100%的缩放显示。

etw的信息提取 

https://docs.microsoft.com/en-us/windows-hardware/test/wpt/xperf-actions
xperf -tle –i myetw.etl -o providers.csv -a dumper -provider {CA80A0D7-6CA2-4F62-B22D-D0F88D79AE4B}


https://docs.microsoft.com/en-us/windows-hardware/test/weg/instrumenting-your-code-with-etw

Copy your component to the location that was specified in your manifest by the resourceFileName attribute:

xcopy /y MyProviderBinary.exe %temp%

Register the providers:

wevtutil um etwmanifest.man
wetvutil im etwmanifest.man

Verify that the provider is visible:

logman query providers

Your provider name/GUID will appear in the list.

1.Start tracing:
  xperf -start MySession -on MyEventProvider -f MySession.etl
  # In that command line, -start gives the event collection session a name, and -on tells ETW that you want to collect events from your provider in this session. (There can be multiple -on arguments.)
2.Execute your workload.
3.Stop tracing:
  xperf -stop MySession

@echo off
echo "clean session.."
xperf -stop app_session -d app_tmp.etl
xperf -stop -d base_tmp.etl
if exist app_tmp.etl (del app_tmp.etl)
if exist base_tmp.etl (del base_tmp.etl)

echo "open session.."
set now=%date:~0,4%%date:~5,2%%date:~8,2%_%time:~0,2%%time:~3,2%%time:~6,2%
set now=%now: =0%
echo %now%
xperf -start -on Base
xperf -start app_session -on CA80A0D7-6CA2-4F62-B22D-D0F88D79AE4B

echo "请启动prometheus应用。"

timeout 100

xperf -stop app_session -d  app_tmp.etl
xperf -stop -d base_tmp.etl
xperf -merge base_tmp.etl app_tmp.etl prometheus_%now%.etl

xperf -tle -i abc_%now%.etl -o hardfaults_%now%.csv -a hardfault -file -bytes
xperf -tle -i abc_%now%.etl -o time_%now%.csv -a dumper -provider {CA80A0D7-6CA2-4F62-B22D-D0F88D79AE4B}
