My first PowerShell script that I knocked together to do one thing. Can I admit that I kinda liked PowerShell?

Perf2CSV.ps1

# Quick & dirty PowerShell script for polling Windows PerfMon counters and dumping into a CSV file 

# setup PowerShell internals
$1GBInBytes = 1GB
$Computer = $env:COMPUTERNAME

# Set the log destination directory
$LogDir="C:\MTGLogs\" 

# Set the performance counters below
# customize as needed
$perfcounters = @("\Memory\Available Bytes",
        "\Memory\Committed Bytes",
        "\Memory\Pages/sec",
        "\PhysicalDisk(_Total)\Current Disk Queue Length",
        "\PhysicalDisk(_Total)\% Disk Time",
        "\Processor(_Total)\% Processor Time"
        "\Processor(_Total)\Interrupts/sec",
        "\System\Processor Queue Length",
        "\Network Interface(dw1520 wireless-n wlan half-mini card)\Output Queue Length",
        "\Network Interface(dw1520 wireless-n wlan half-mini card)\Bytes Received/sec",
        "\Network Interface(dw1520 wireless-n wlan half-mini card)\Bytes Sent/sec");

# set up the file names and paths for logs
$date = Get-Date -Format 'yyyy_MM_dd-HH_mm_ss'
$LogFile = "$LogDir\Perfs_log_$date.csv"
# create the log directory if missing
if( !(test-path $LogDir)) {New-Item $LogDir -type directory}
#
# get the performance counters. 
#  Set -SampleInterval in seconds (currently every 10 sec.)
#  Set -MaxSamples in number of samples (e.g. for 5 minutes of samples set to 30)
#   can also use -continous instead of -MaxSampes n to run until stopped
Get-Counter -counter $perfcounters -SampleInterval 10 -MaxSamples 60 | export-counter -Path $LogFile -FileFormat CSV
