Monitor performance counter with WMI and SQL Server.

WMI is very important to use as central monitoring task. I have created performance monitoring which checks Disk Queue Legth, Disk Read/Sec, Disk Write/Sec, CPU Usage, Memory Usage, Disk Read Bytes/Sec, Disk Write Bytes/Sec, ASP Request/Sec. Create a table “PerformanceCounter” to store all information.

USE [Adventureworks2012]
GO

/****** Object: Table [dbo].[PerformanceCounter] Script Date: 05/27/2013 12:35:07 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

SET ANSI_PADDING ON
GO

CREATE TABLE [dbo].[PerformanceCounter](
 [ServerName] [varchar](20) NULL,
 [CounterName] [varchar](100) NULL,
 [CounterValue] [varchar](100) NULL,
 [CreatedDate] [datetime] NULL
) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

ALTER TABLE [dbo].[PerformanceCounter] ADD DEFAULT (getdate()) FOR [CreatedDate]
GO

Open Notepad and save below code with “PerformanceCount.vbs”.
