Configuring Inventory Processor

Settings Description

Inventory Processor is the executable module file responsible for populating the asset database. The standard executable file name is: moduleInventory-<version>.

Configuration File

To run Inventory Processor, a configuration file named config.yml must be present in the module folder. It contains the following parameters:

Parameter	Description	Required
opensearch	List of OpenSearch cluster servers.	Yes
username	Username for connection.	Yes
password	Password for connection.	Yes
cert	CA certificate for authentication verification.	Yes
join_events_with_null_value	Skip empty keys during the aggregation stage.	No
include_assets	List of asset configurations requiring processing. If not specified, all configurations will be processed.	No

Example config.yml content:

opensearch: ['https://172.16.0.60:9200']
username: 'admin'
password: 'pass'
cert: 'root-ca.pem'
join_events_with_null_value: false
include_assets:
  - asset_name: 'Hosts'
    search_fields: ['hostname']

danger

If you need to hide the password from the Inventory configuration file, the username and password parameters can be omitted from the configuration file and specified via environment variables instead: SM_INV_USERNAME and SM_INV_PASSWORD.

Environment variable values override parameters set in the configuration file. To pass environment variables to a cron job, define them in the /home/opensearch/.profile file and run the cron job via bash. Access to the /home/opensearch/.profile file should be strictly limited, allowing only the root user and the user running the service to read it.

Example crontab for the opensearch user:

* * * * * bash -l -c "cd /app/inventory; ./moduleInventory"

Example /home/opensearch/.profile:

export SM_INV_USERNAME=admin
export SM_INV_PASSWORD=VeryStrongPassword
