The Power of the SeeShell – PowerShell

I’m having the opportunity to test the SeeShell , a tool from Code Owls LLC (read Jim Christopher (@beefarino), created. I can say that so far I’m impressed. I will do some posts but for now I want to show a bit about the power of this tool (guys,you did not see the real-time display counters. it is AMAZING !!! I will show that in our PASS VC PowerShell meeting tomorrow )

I have a module to gathering the performance counters,it is easy to use and scale to n servers , in asynchronous mode using background jobs, with a command line .

In this module I have the option to store into a SQL Server table :



You can see that just for some test, I am using the counters Buffer Cache Hit Ratio and % Processor Time.

Obvious that is not the case in here, but we know that on SQL Server mostly  counters cannot be checked alone. So let´s say, just for test, that I need to check out this 2 counters, in a graphical mode.

First I need to aggregate my data by date :

   1: $ServerName = "Obiwan"                

   2: $Query = "

   3: with CTEPerfCounters_$($ServerName) ([date] ,[Buffer cache hit ratio],[%_Processor_Time])

   4: as

   5: (

   6:     select    substring(convert(varchar(10),[datetime],111),1,10) as Date,

   7:             avg([$($ServerName)_SQLServer:Buffer Manager_Single Instance_Buffer cache hit ratio]) ,

   8:             avg([$($ServerName)_Process_sqlservr_% Processor Time])

   9:     from    PerfCounters_$($ServerName)

  10:     group by substring(convert(varchar(10),[datetime],111),1,10)



  13: )

  14: select * from CTEPerfCounters_$($ServerName);"

  15: $Data = Invoke-Sqlcmd2 -Query $Query -Database SQLServerRepository    

Then  with a command line I can See..Shell Alegre

   1: $Data | out-chart -name 'SQL Server Counters - ObiWan' -type column -plot '%_Processor_time','Buffer cache hit ratio' -by date




Or If I want just the CPU History :

   1: $Data | out-chart -name 'CPU History - ObiWan' -type column -plot '%_Processor_time' -by date




What AWESOMESAUCE tool !!!! (that is a bit that we can do with SeeShell)

As Jim says….SeeShell….Show, Don’t Tell  Alegre
