Hey, Scripting Guy! I have recently inherited a Microsoft SQL Server 2008 R2 box, and I am concerned about the thing. I am not a DBA, and to be honest the server sort of frightens me a bit. When I look into the Application log, there is lots of information about SQL, but it all seems to be SPAM, and it does not really seem to tell me much useful information. I am wondering if Windows PowerShell can help me with this server, and if so, where is the re

When server numbers get large, the traditional Windows GUI approach breaks down, and the PoSH DBA reaches for a sqlpsx PowerShell script to do the leg-work. 18 10 Laerte Junior "I know I'm searching for something Something so undefined that it can only be seen by the eyes of the blind in the middle https://blogs.technet.microsoft.com/heyscriptingguy/2011/05/31/use-powershell-to-get-the-sql-server-error-log/ of the night."

With SQL Server, we have two major sources of information for doing this: the SQL Server Error Log and the Event Viewer. When a problem occurs in SQL Server, ranging from a logon failure to a severe error in database mirroring, the first place to look for more information is the SQL Server Error Log. Similarly, if we have a problem related to physical hardware, the disk for example, we will look in the Event Viewer. Both the SQL Server Error Log and the Event Viewer are designed to be used via their respehere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the http://stackoverflow.com/questions/32698690/how-to-get-powershell-to-read-a-sql-server-error-log workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs http://www.mikefal.net/2016/01/26/managing-sql-error-logs-with-powershell/ Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 6.2 million programmers, just like you, helping each other.

I have a SQL Server instance (on a server named VMDEV-APP11) configured as a Central Management Server (CMS) in which I have registered all my Dev/Test/Prod SQL instances windows event log and I want to use PowerShell to read the SQL Server error logs from all my servers. I have a query which retrieves all my SQL Server instances but when I pipe the output of this into a call to ReadErrorLog, I get an error. This is the code that retrieves my list of the SQL Server instances which are registered on my CMS (note that I exclude my SQL Server 2000 instances): Set-Location D:\MSSQL11.MSSQLSERVER\CMS # Define functions to query SQL Server and write data to a SQL table . ./invoke-sqlcmd2.ps1 . ./write-datatable.ps1 Invoke-sqlcmd2 -ServerInstance "VMDEV-APP11" -Database dba -Query "select s.server_name from msdb.dbo.sysmanagement_shared_registered_servers s, msdb.dbo.sysmanagement_shared_server_groups g where s.server_group_id = g.server_group_id and g.name not like '2000%'" server_name ----------- INF-SRV14 VMDEV-APP15 NEX-SRV48 ... And this is what I thought would work and the error I actually get: Invoke-sqlcmd2 -ServerInstance "VMDEV-APP11" -Database dba -Query "select s.server_name from msdb.dbo.sysmanagement_shared_registered_servers s, msdb.dbo.sysmanagement_shared_server_groups g where s.server_group_id = g.server_group_id and g.name not like '2000%'" | foreach-object { $_.server_name.ReadErrorLog() } Error: Method invocation failed because [System.String] does not contain a method named 'ReadErrorLog'.

I will ask is “what’s the error message?” Error logs and messages are extremely helpful, even if they feel vague. Because of this, it is vital to know how to leverage the error logs in SQL Server whenever you are troubleshooting an issue. The challenge is managing these logs efficiently and parsing them in a effective way. Powershell can offer some useful tools for reading and manipulating your logs, especially if you want to collect information across multiple SQL Server instances. I’m not the first person to write about these methods. Buck Woody(@BuckWoodyMSFT) covers the basic method well and Allen White(@SqlRunr) has his own post that goes into more detail. I want to provide a little more information and expand on how it can be useful to you. Getting Started Reading SQL Server error logs is pretty simple, but requires us to make use of the SMO objects and the .ReadErrorLog() method to get the data from the log. Let’s start by simply reading the SQL Server error log and see what the output looks like (I’ll be using the SQL Server provider for this): (Get-Item SQLSERVER:\SQL\localhost\DEFAULT).ReadErrorLog() Nothing too surprising here, so let’s dig a little deeper. As I reiterate whenever I talk to folks about Powershell, everything is a .Net object. With this in mind, let’s see what we’re dealing with: $log = (Get-Item SQLSERVER:\SQL\localhost\DEFAULT).ReadErrorLog() $log | Get-Member Look at the output’s data type, which is a System.Data.DataRow object. This is useful to us because it is a strongly typed object, not just a collection of strings, giving us better access to the data within the log. Now we can access the properties of the output and our data directly. Notice the highlighted properties, which are the output columns. Let’s leverage these properties to filter our data: $log | Where-Object {$_.Text -like '*Startup*'} | Sort-Object LogDate | Format-List Text What’s going on here? First off, we take the object and filter out only rows where the Text column/property value is like ‘Startup’. Next we sort by the LogDate column/property to make sure the data displays oldest to newest. Finally, the output is formatted to show only
