Deploy the Collector for Linux with Chef 🔗
Chef is a configuration management technology used to manage infrastructure on physical or virtual machines. Chef uses cookbooks to define a scenario.
Cookbooks are fundamental working units of Chef, which consists of all the details related to working units, having the capability to modify configuration and the state of any system configured as a node on Chef infrastructure. Cookbooks can run multiple tasks.
Prerequisites 🔗
You need the following resources to use Chef:
Double-check exposed ports to make sure your environment doesn’t have conflicts. You can change ports in the Collector configuration. See Exposed ports and endpoints for more information.
Linux 🔗
The Collector supports the following Linux distributions and versions:
Amazon Linux: 2, 2023.
CentOS: 7, 8, 9
Red Hat: 7, 8, 9
Oracle: 8, 9
Debian: 11, 12
SUSE: 12, 15 for version 0.34.0 or higher.
Ubuntu: 16.04, 18.04, 20.04, 22.04, and 24.04
Rocky Linux: 8, 9
Install and use the Collector with Chef 🔗
Download the Chef cookbook from the Chef Supermarket , which is the site for community cookbooks.
To install the Collector, include the splunk_otel_collector::default recipe in the run_list, and set the attributes on the node’s run_state. The following is an example configuration that shows how to configure the required splunk_access_token attribute and some optional attributes:
{
"splunk-otel-collector": {
"splunk_access_token": "<SPLUNK_ACCESS_TOKEN>",
"splunk_realm": "<SPLUNK_REALM>",
}
}
Attributes for Linux 🔗
For Linux, the cookbook accepts the attributes described in the following table:

Configure automatic discovery for back-end applications (Linux only) 🔗
You can automatically instrument your back-end applications applications along with the Collector installation using automatic discovery. Automatic discovery removes the need to install and configure OpenTelemetry agents separately. See Automatic discovery of apps and services for more information. The applications to be instrumented on the node need to be started or restarted separately after installation or any configuration changes for automatic discovery to take effect.
The following table shows the variables that can be configured with this Chef cookbook:
