Puppet for Windows 🔗

Use this module to install and configure the Collector on Windows. Download and install the module from Puppet Forge. After downloading the module, you can add customizations using the class parameter.

Currently, we support the following Windows versions. All versions require using PowerShell 3.0 or newer.

  • Windows Server 2012 64-bit

  • Windows Server 2016 64-bit

  • Windows Server 2019 64-bit

On Windows systems, the puppetlabs/registry module is required to set the registry key/values, and the puppetlabs/powershell module is required to execute Powershell commands.

Using the module 🔗

To use this module, include the splunk_otel_collector class in your manifests with the supported parameters (see Modify the class parameters for descriptions of the available parameters). For example, the following deployment definition is the simplest deployment definition with the default parameters (replace VERSION with the desired Collector version, SPLUNK_ACCESS_TOKEN with your Splunk access token to authenticate requests, and SPLUNK_REALM for the realm to send the data to):

class { splunk_otel_collector:
  collector_version => 'VERSION'
  splunk_access_token => 'SPLUNK_ACCESS_TOKEN',
  splunk_realm => 'SPLUNK_REALM',
}

Modify the class parameters 🔗

The class accepts the parameters described in the following table:

Name

Description

Default value

collector_version

Version of the Collector package to install, for example, 0.25.0. The version should correspond to Github Releases without the preceding v. This attribute is required.

None

splunk_access_token

The Splunk access token to authenticate requests. This attribute is required.

None

splunk_realm

Which realm to send the data to, for example, us0. The Splunk ingest and API URLs are inferred by this value. The SPLUNK_REALM environment variable is set with this value for the collector service. This attribute is required.

None

splunk_ingest_url

Sets the Splunk ingest URL explicitly instead of the URL inferred by the $splunk_realm parameter. The SPLUNK_INGEST_URL environment variable is set with this value for the Collector service.

https://ingest.${splunk_realm}.signalfx.com

splunk_api_url

Sets the Splunk API URL explicitly instead of the URL inferred by the $splunk_realm parameter. The SPLUNK_API_URL environment variable is set with this value for the Collector service.

https://api.${splunk_realm}.signalfx.com

splunk_trace_url

Sets the Splunk trace endpoint URL explicitly instead of the URL inferred by the $splunk_ingest_url parameter. The SPLUNK_TRACE_URL environment variable is set with this value for the Collector service.

${splunk_ingest_url}/v2/trace

splunk_hec_url

Sets the Splunk HEC endpoint URL explicitly instead of the URL inferred by the $splunk_ingest_url parameter. The SPLUNK_HEC_URL environment variable is set with this value for the Collector service.

${splunk_ingest_url}/v1/log

splunk_hec_token

Sets the Splunk HEC authentication token if different than $splunk_access_token. The SPLUNK_HEC_TOKEN environment variable is set with this value for the Collector service.

$splunk_access_token

splunk_bundle_dir

The path to the Smart Agent bundle directory. The default path is provided by the Collector package. If the specified path is changed from the default value, the path should be an existing directory on the node. The SPLUNK_BUNDLE_DIR environment variable is set to this value for the Collector service.

%PROGRAMFILES%\Splunk\OpenTelemetry Collector\agent-bundle

splunk_collectd_dir

The path to the collectd configuration directory for the Smart Agent bundle. The default path is provided by the Collector package. If the specified path is changed from the default value, the path should be an existing directory on the node. The SPLUNK_COLLECTD_DIR environment variable is set to this value for the Collector service.

${splunk_bundle_dir}\run\collectd

splunk_memory_total_mib

Total memory in MIB to allocate to the Collector; automatically calculates the ballast size. The SPLUNK_MEMORY_TOTAL_MIB environment variable is set to this value for the Collector service.

512

splunk_ballast_size_mib

Sets the ballast size for the Collector explicitly instead of the value calculated from the $splunk_memory_total_mib parameter. This should be set to 1/3 to 1/2 of the configured memory. The SPLUNK_BALLAST_SIZE_MIB environment variable is set to this value for the Collector service.

None

collector_config_source

The source path to the Collector configuration YAML file. This file is copied to the $collector_config_dest path on the node. See the source attribute of the file resource for the supported value types. The default source file is provided by the Collector package.

%PROGRAMFILES\Splunk\OpenTelemetry Collector\agent_config.yaml

collector_config_dest

Destination path of the Collector configuration file on the node. The SPLUNK_CONFIG environment variable is set with this value for the Collector service.

%PROGRAMDATA%\Splunk\OpenTelemetry Collector\agent_config.yaml

with_fluentd

Whether to install or manage Fluentd and dependencies for log collection.

true

fluentd_config_source

Source path to the Fluentd configuration file. This file is copied to the $fluentd_config_dest path on the node. See the source attribute of the file resource for the supported value types. The default source file is provided by the Collector package. Only applicable if $with_fluentd is set to true.
