Тестирование скорости диска
15 Mar 2017Есть задумка выполнять проверку текущей скорости диска из системы мониторинга Icinga2. На данный момент разбираюсь с консольной утилитой diskspd. В дальнейшем планирую написать скрипт на powershell для выполнения проверки агентом Icinga2.
В процессе ...
Примеры использования:
#Создание файла размером 50MB
$f = new-object System.IO.FileStream c:\temp\io.dat, Create, ReadWrite
$f.SetLength(50MB)
$f.Close()
cd "C:\temp\Diskspd-v2.0.17\amd64fre"
.\diskspd -d60 -F1 -r -w50 -b4k -o10 -Rxml -D -L c:\temp\io.dat | Add-Content c:\temp\result_c.xml
.\diskspd -d60 -F1 -r -w50 -b4k -o10 -Rxml -D -L d:\temp\io.dat | Add-Content c:\temp\result_d.xml
.\diskspd -d60 -F1 -r -w50 -b4k -o10 -Rxml -D -L e:\temp\io.dat | Add-Content c:\temp\result_e.xml
..\process-diskspd.ps1 c:\Temp c:\temp\result.csv
