Ingest syslog data
The following configuration example shows how to configure a Collector instance to receive data from syslog and send it to the Dynatrace backend.
Prerequisites
- One of the following Collector distributions with the Syslog receiver
- The Dynatrace Collector
- OpenTelemetry Contrib
- A custom Builder version
- The API URL of your Dynatrace environment
- An API token with the relevant access scope

Components
For our configuration, we use the following components.
Receiver
Under receivers, we specify two instances of the syslog receiver as active receiver components for our Collector instance.
The Syslog receiver supports a number of configuration parameters, which enable you to customize its behavior. For our example, we use the following:
tcp—Specifies a TCP listener for the receiver and configures ports 54526 and 54527protocol—Specifies the RFC 5424 implementation for our receiver (alternatively, RFC 3164 is also supported)operators—Configures the operators we apply to each log entry. For our example, we use the add operator to add additional information.field—Specifies the name of value we are addingvalue—Specifies the content of the value we are adding
Exporter
Under exporters, we specify the default otlphttp exporter and configure it with our Dynatrace API URL and the required authentication token.
For this purpose, we set the following two environment variables and reference them in the configuration values for endpoint and Authorization.
DT_ENDPOINTcontains the base URL of your ActiveGate (for example,https://{your-environment-id}.live.dynatrace.com/api/v2/otlp)DT_API_TOKENcontains the API token
Service pipeline
Under service, we eventually assemble our receiver and exporter objects into a traces pipeline, which uses the receiver instances to obtain syslog data and ingest it into Dynatrace using OTLP.
Limits and limitations
Logs are ingested using the OpenTelemetry protocol (OTLP) via the Dynatrace OTLP API and are subject to the API's limits and restrictions. For more information see:
