Syslog (RFC5424) output

The syslog output sends log records over a socket using the Syslog protocol (RFC 5424).

  spec:
    syslog:
      host: 10.12.34.56
      transport: tls
      tls:
        ca_file:
          mountFrom:
            secretKeyRef:
              name: tls-secret
              key: ca.crt
        cert_file:
          mountFrom:
            secretKeyRef:
              name: tls-secret
              key: tls.crt
        key_file:
          mountFrom:
            secretKeyRef:
              name: tls-secret
              key: tls.key

The following example also configures disk-based buffering for the output. For details, see the Syslog-ng DiskBuffer options.

For details on the available options of the output, see the syslog-ng documentation.

host (string, required)

Address of the destination host

Default: -

port (int, optional)

The port number to connect to. more information

Default: -

transport (string, optional)

Specifies the protocol used to send messages to the destination server. more information more information

Default: -

close_on_input (*bool, optional)

By default, syslog-ng OSE closes destination sockets if it receives any input from the socket (for example, a reply). If this option is set to no, syslog-ng OSE just ignores the input, but does not close the socket. more information

Default: -

flags ([]string, optional)

Flags influence the behavior of the destination driver. more information

Default: -

flush_lines (int, optional)

Specifies how many lines are flushed to a destination at a time. more information

Default: -

so_keepalive (*bool, optional)

Enables keep-alive messages, keeping the socket open. more information

Default: -

suppress (int, optional)

Specifies the number of seconds syslog-ng waits for identical messages. more information

Default: -

template (string, optional)

Specifies a template defining the logformat to be used in the destination. more information

Default: 0

template_escape (*bool, optional)

Turns on escaping for the ‘, “, and backspace characters in templated output files. more information

Default: -

tls (*TLS, optional)

Sets various options related to TLS encryption, for example, key/certificate files and trusted CA locations. more information

Default: -

ts_format (string, optional)

Override the global timestamp format (set in the global ts-format() parameter) for the specific destination. more information

Default: -

disk_buffer (*DiskBuffer, optional)

Enables putting outgoing messages into the disk buffer of the destination to avoid message loss in case of a system failure on the destination side. For details, see the Syslog-ng DiskBuffer options.

Default: -

persist_name (string, optional)

Unique name for the syslog-ng driver more information

Default: -
