Use Observability Pipelines’ syslog destinations to send logs to rsyslog or syslog-ng.

Setup

Set up the rsyslog or syslog-ng destination and its environment variables when you set up a pipeline. The information below is configured in the pipelines UI.

Set up the destination

The rsyslog and syslog-ng destinations match these log fields to the following Syslog fields:

The following destination settings are optional:

1. Toggle the switch to enable TLS. If you enable TLS, the following certificate and key files are required:
   • Server Certificate Path: The path to the certificate file that has been signed by your Certificate Authority (CA) Root File in DER or PEM (X.509).
   • CA Certificate Path: The path to the certificate file that is your Certificate Authority (CA) Root File in DER or PEM (X.509).
   • Private Key Path: The path to the .key private key file that belongs to your Server Certificate Path in DER or PEM (PKCS#8) format.
2. Enter the number of seconds to wait before sending TCP keepalive probes on an idle connection.

Set the environment variables

• The rsyslog or syslog-ng endpoint URL. For example, 127.0.0.1:9997.
  • The Observability Pipelines Worker sends logs to this address and port.
  • Stored as the environment variable: DD_OP_DESTINATION_SYSLOG_ENDPOINT_URL.

How the destination works

Event batching

The rsyslog and syslog-ng destinations do not batch events.
