Sumo Logic Forwarder (via OTel)

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

Sumo Logic supports OTLP over HTTP ingestion for logs through an OTLP/HTTP Source that you create in the Sumo Logic UI. Apica’s OpenTelemetry Logs Forwarder can send logs directly to this endpoint without deploying an intermediate OpenTelemetry Collector.

---

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 Sumo Logic account

• You can create or modify Hosted Collectors and Sources in Sumo Logic

How Sumo Logic Ingests OpenTelemetry Logs

Sumo Logic ingests OpenTelemetry data using OTLP/HTTP Sources that are attached to a Hosted Collector.

Key points:

• You must create an OTLP/HTTP Source in Sumo Logic

• Sumo Logic generates a unique source URL

• OpenTelemetry clients send data to this URL using signal-specific paths:

  • /v1/logs for logs

  • /v1/metrics for metrics

  • /v1/traces for traces

• Authentication is handled by the source URL itself (no API token header is required)

Important You cannot use a generic or static Sumo Logic OTLP endpoint. The generated OTLP/HTTP Source URL is required to associate data with your account.

Create an OTLP/HTTP Source in Sumo Logic

1. Log in to Sumo Logic

2. Navigate to Manage Data → Collection

3. Select an existing Hosted Collector (or create one)

4. Click Add Source

5. Choose OTLP/HTTP

6. Enter a Name (for example, Apica OTLP Logs)

7. (Optional) Set metadata such as Source Category

8. Click Save

After saving, click Show URL to copy the OTLP/HTTP Source base URL.

This URL will look similar to:

https://<unique-id>.collection.<region>.sumologic.com/otlp

Configure the OpenTelemetry Logs Forwarder in Apica

In the Ascent UI, create a new forwarder:

1. Navigate to Forwarders

2. Select Create Forwarder

3. Choose OpenTelemetry Logs

---

Forwarder Configuration

Required Fields

Field	Value
Name	sumologic-otlp-logs
Endpoint	<OTLP_HTTP_SOURCE_URL>/v1/logs
Headers	(none required)
Output Format	proto

Example Endpoint

https://abcd1234.collection.us2.sumologic.com/otlp/v1/logs

Notes

• Do not omit /v1/logs

• Do not add authentication headers

• Use proto for optimal compatibility and performance

---

Map the Forwarder to Log Sources

Creating the forwarder does not automatically forward logs.

To enable forwarding:

1. Go to Explore

2. Select the application or namespace receiving logs

3. Open the Actions (⋯) menu

4. Select Map Forwarder

5. Choose sumologic-otlp-logs

6. Save

Only mapped sources will send logs to Sumo Logic.
