Thanks. If folks have ideas on things to add to it, let me know and I can work them in and share the script.

This looks like some great stuff, however I am new to powershell. Do you have any step by step instructions for running the scripts? I would like to try it out in my test servers.

Thanks,

David

I don't have anything step by step - but I could easily create a step by step article or a set of blog posts that cover it. Is that something people would like to see? It could be articles or I could just blog it in small bites.

The script I uploaded should be able to be run as long as you have Powershell 2 installed without any issues. (you shouldn't need any experience) Just give it a server name and a few hours and let it run.

nice article, going to have to look at it. right now i have perfmon running on a server dumping data to a central database where i run reports from. this is a lot lighter, but i was going to use the perfmon data for historical baselines as well. one thing i don't like about powershell is that you can't seem to dump the data into SQL

You can dump directly to SQL, I do that for gathering stats for our VM admins. I don't like looking at csvs or text files anymore than the next DBA.

Once you have a list of counters (note I have some extra properties in my object collection) - you could simply call a proc (or just directly insert them)

$CounterCollection | Where-Object{$_.Path -ne $null} | ForEach-Object{

$qry = "EXEC .dbo.pr_Add_Perf_Collection "

$qry = $qry + " @server='" + [string]$_.Server + "'"

$qry = $qry + ", @performance_metric='" + [string]$_.Path + "'"

$qry = $qry + ", @performance_value=" + [decimal]$_.CookedValue

$qry = $qry + ", @date_sampled='"+ $_.Timestamp + "'"

$qry = $qry + ", @samples_taken=" + $_.Samples

$qry = $qry + ", @sample_interval=" + [int]$_.SampleInterval

Invoke-SqlNonQuery -ServerInstance $SQLServerToStore -Query $qry

}

function Invoke-SqlNonQuery{

param(

[string]$ServerInstance,

[string]$Query

)

$QueryTimeout=30

$conn=new-object System.Data.SqlClient.SQLConnection

$constring = "Server=" + $ServerInstance + ";Integrated Security=True"

$conn.ConnectionString=$constring

$conn.Open()

if($conn){

$cmd=new-object system.Data.SqlClient.SqlCommand($Query,$conn)

$cmd.CommandTimeout=$QueryTimeout

$cmd.ExecuteNonQuery() | out-null

$conn.Close()

}

Hope this helps. I will see about writing a perfmon metric gather/storage article if SSC wants to publish it.

Examples would be helpful how to pipe data directly to sql server database.

This is probably what you are looking for http://gallery.technet.microsoft.com/scriptcenter/2fdeaf8d-b164-411c-9483-99413d6053ae

Note it uses bulkcopy and there are some restrictions with that.

How could you exclude certain error codes in array string?

The below example does not seem to filter errors from my array.

Ex.

$IgnoreErrorCode=@(

'1608',

'17832',

'17824',

'18456';

)

# Write-Host "Reading SQL Log for $sqlServerName"

try{

$sqlServer.ReadErrorLog() | Where{$_.LogDate -is [datetime] } |

Where-Object{$_.LogDate -gt $DatetoCheck } |

Where-Object{$_.Text -like "*Error*" -or $_.Text -like "*Fail*"} -and ($_.Text -notcontains $IgnoreErrorCode) |

Select-Object LogDate,Text |

Out-GridView -Title "$sqlServerName Log Errors"

} catch {

Write-Host "Error Reading $sqlServer.Name"

}

As a norm, I only use double quotes when I intend the string to be interpolated. When I want to use the string as it is, I use single quotes. It's not much, but why waste CPU and time for nothing?

You can filter the WMI instances in the query:

Get-WmiObject -Class Win32_Service -Filter 'Name like "%SQL%"'
