Exports data via gRPC using skywalking-data-collect-protocol format. By default, this exporter requires TLS and offers queued retry capabilities.

The following settings are required:

• endpoint (no default): host:port to which the exporter is going to send SkyWalking log data, using the gRPC protocol. The valid syntax is described here. If a scheme of https is used then client transport security is enabled and overrides the insecure setting.

• num_streams (default = 2): the number of grpc streams that send the gRPC requests.

By default, TLS is enabled and must be configured under tls::

• insecure (default = false): whether to enable client transport security for the exporter's connection.

As a result, the following parameters are also required under tls::

• cert_file (no default): path to the TLS cert to use for TLS required connections. Should only be used if insecure is set to false.
• key_file (no default): path to the TLS key to use for TLS required connections. Should only be used if insecure is set to false.

Example:

exporters:
  skywalking:
    endpoint: "192.168.1.5:11800"
    tls:
      insecure: true  
    num_streams: 5  
  skywalking/2:
    endpoint: "10.18.7.4:11800"
    compression: "gzip"
    tls:
      cert_file: file.cert
      key_file: file.key
    timeout: 10s

Several helper files are leveraged to provide additional capabilities automatically:

• gRPC settings
• TLS and mTLS settings
• Queuing, retry and timeout settings
