Publisher

The publisher subsystem is a pluggable interface for outbound messages, structured following the OpenConfig / IETF YANG models. The messages can be published over a variety of services – see Available publishers and their options. From the command line, the publisher module can be selected using the --publisher option, e.g.:

$ napalm-logs --publisher kafka

From the configuration file, the publisher can be specified using the publisher option, eventually with several options. The options depend on the nature of the publisher.

Example: publisher configuration using the default configuration

publisher: zmq

Example: publisher configuration using custom options

publisher:
  kafka:
    topic: napalm-logs-out

Note

The IP Address / port for the publisher be specified using the publish-address and publish-port configuration options.

Available publishers and their options

• CLI
• Kafka
• Log
• ZeroMQ

Additionally, the user can configure the following options, available to all publishers:

send_raw

If this option is set, all processed syslog messages, even ones that have not matched a configured error, will be published over the specified transport. This can be used to forward to log server for storage.

Example:

publisher:
  zmq:
    send_raw: true

send_unknown

If this option is set, all processed syslog messages, even ones that have not matched a certain operating system, will be published over the specified transport. This can be used to forward to log server for storage.

Example:

publisher:
  kafka:
    send_unknown: true
