Script: Enable and collect ExTRA tracing across all Exchange servers


Here is a PowerShell script that can be used to kick off an ExTRA trace on every Exchange server in the org and collect the traces into a single location. I’ve highlighted in red the variables you’ll likely want to edit prior to running the script.

# Description:
#   Initiates an ExTRA trace on all the Exchange 2013 servers
#   in an environment and collects the results into a single location.
# Use:
#   In an Exchange Management Shell (EMS), run either of these commands:
#     .\extraTrace.ps1 -Start
#     .\extraTrace.ps1 -Stop

 [switch]$Start,
 [switch]$Stop
)

# check that user ran with either Start or Stop switch params
if (($Start -and $Stop) -or (-not $Start -and -not $Stop)) {
 Write-Error "Please specify only 1 parameter: -Start or -Stop."
 exit
}

$traceConfigFilepath = "C:\EnabledTraces.Config"
$script:nl = "`r`n"
# network path to save the resulting traces (default is local c:\temp\extra)
$TRACES_FILEPATH = "\\" + (hostname) + "\c$\temp\extra"
