Configuring components

Select a node on the canvas to open its configuration panel on the right. Each component type has a form with the fields that component supports, such as endpoints, protocols, intervals, and attribute rules.

Edit a component

1. Select the node on the canvas.
2. Edit the fields in the configuration panel. Changes are reflected in the generated YAML immediately.
3. Telflo validates the configuration as you edit and reports problems in the validation status. See Validation.

Forms are specific to each component. For example, an OTLP exporter has endpoint and TLS fields, a batch processor has size and timeout fields, and a transform processor has its OTTL statements.

The OTLP/HTTP exporter's form includes a Quick Setup dropdown that pre-fills the endpoint and authentication header for a chosen destination, with a placeholder credential to replace. Every component has an Instance Name field that creates a named instance in the YAML, such as otlphttp/staging, so the same component type can appear more than once.

Anything not exposed by a form can be edited directly in the YAML view. The canvas and the YAML stay in sync.

Reference a variable

Reference a value stored in the vault instead of typing the same value into many fields.

• Type @ to reference an organization variable. Selecting one inserts a $orgvar: token, such as $orgvar:PROD_API_URL, which stays in the YAML and is resolved for each collector when it checks in. Update the value in the vault, and collectors receive it on their next check-in.
• Type # to insert a user variable. Selecting one inserts the variable's value into the field, so the generated YAML contains the literal value.

For credentials such as API keys and tokens, reference an environment variable with ${env:NAME} so the value comes from the host environment and is not stored in the configuration.

Next steps

• Review the generated configuration. See YAML editor.
• Resolve issues reported by validation. See Validation.
