Install the Collector for Windows using the installer script 🔗
The installer script is available for Windows 64-bit environments, and deploys and configures the Splunk Distribution of the OpenTelemetry Collector for Windows.
To install the package using the installer script, follow these steps:
Ensure that you have Administrator access on your host.
Run the following PowerShell command on your host, replacing the following variables for your environment:
SPLUNK_REALM: This is the realm to send data to. The default isus0. See realms .SPLUNK_ACCESS_TOKEN: This is the base64-encoded access token for authenticating data ingest requests. Your access token needs to have the ingest authorization scope. See Create and manage organization access tokens using Splunk Observability Cloud.
& {Set-ExecutionPolicy Bypass -Scope Process -Force; $script = ((New-Object System.Net.WebClient).DownloadString('https://dl.signalfx.com/splunk-otel-collector.ps1')); $params = @{access_token = "SPLUNK_ACCESS_TOKEN"; realm = "SPLUNK_REALM"}; Invoke-Command -ScriptBlock ([scriptblock]::Create(". {$script} $(&{$args} @params)"))}
If you need to activate TLS in PowerShell, use the command:
[Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12
Caution
Starting from version 0.89, the installer for the Splunk Distribution of the OpenTelemetry Collector for Windows sets its configuration using environment variables at service level instead of global level. To configure additional settings use service, process, or terminal scopes.
Start the Collector executable manually 🔗
If you experience unexpected start failures, try to start the Collector executable manually.
To do so, run the following PowerShell command as an Admin:
& 'C:\Program Files\Splunk\OpenTelemetry Collector\otelcol.exe' --config 'C:\ProgramData\Splunk\OpenTelemetry Collector\agent_config.yaml'
