ITRS Geneos Forwarder (via OTel)

This guide explains how to forward logs from Apica Ascent / Flow to Geneos using the OpenTelemetry (OTLP) Logs Forwarder over HTTPS.

The OpenTelemetry Logs Forwarder converts logs ingested into Apica into OTLP-compliant log data and forwards them to a remote OTLP/HTTP endpoint.

---

Prerequisites

Before configuring the forwarder, ensure the following:

• Logs are already being ingested into Apica Ascent

• You have access to the Ascent UI with permissions to create forwarders

• You have a Geneos deployment with OpenTelemetry ingestion enabled

• You have a valid Geneos API token or credentials for OTLP ingestion

---

Geneos OpenTelemetry Support

Geneos supports OpenTelemetry ingestion via OTLP over HTTP. OTLP endpoints and authentication details are deployment-specific and may vary depending on whether Geneos is deployed on-premises, in the cloud, or as part of a managed service.

Note: Confirm the exact OTLP logs endpoint and authentication requirements with your Geneos administrator or Geneos documentation before proceeding.

Geneos OTLP Logs Endpoint

Endpoint format (example):

https://<GENEOS_HOST>/otlp/v1/logs

Authentication is typically performed using an API token or bearer token passed via HTTP headers.

---

Create an OpenTelemetry Logs Forwarder

1. In the Ascent UI, navigate to Forwarders

2. Select Create Forwarder

3. Choose OpenTelemetry Logs as the forwarder type

---

Configuration Fields

Field	Description
Name	A descriptive name for the forwarder (for example, geneos-otlp-logs)
Endpoint	The Geneos OTLP logs endpoint
Headers	HTTP headers to include with each request
Output Format	OTLP payload format

---

Example Configuration

Endpoint

https://<GENEOS_HOST>/otlp/v1/logs

Headers

Authorization=Bearer <GENEOS_API_TOKEN>

Output Format

proto

Note: The OpenTelemetry Logs Forwarder sends OTLP payloads over HTTP. Geneos supports OTLP/HTTP and recommends using the proto format for efficient ingestion.

---

Map the Forwarder to Log Sources

Creating a forwarder does not automatically forward logs. You must map the forwarder to the applications or namespaces whose logs you want to forward.

Map via Explore

1. Navigate to Explore

2. Select the application or namespace receiving logs

3. Open the Actions (⋯) menu

4. Select Map Forwarder

5. Choose the Geneos OTLP logs forwarder

6. Save the mapping

Once mapped, all logs for the selected application or namespace will be forwarded to Geneos.
