Authentication for syslog-ng outputs
Overview
GRPC-based outputs use this configuration instead of the simple tls field found at most HTTP based destinations. For details, see the documentation of a related syslog-ng destination, for example, Grafana Loki.
Configuration
Auth
Authentication settings. Only one authentication method can be set. Default: Insecure
adc (*ADC, optional)
Application Default Credentials (ADC).
alts (*ALTS, optional)
Application Layer Transport Security (ALTS) is a simple to use authentication, only available within Google’s infrastructure.
insecure (*Insecure, optional)
This is the default method, authentication is disabled (auth(insecure())).
tls (*GrpcTLS, optional)
This option sets various options related to TLS encryption, for example, key/certificate files and trusted CA locations. TLS can be used only with tcp-based transport protocols. For details, see TLS for syslog-ng outputs and the documentation of the AxoSyslog syslog-ng distribution.
