Integration for only one application

ChirpStack Application Server
#1

Hi. How to enable integration for only one application?
Example
application_1 = [‘mqtt’]
application_2 = [‘postgresql’]

#2

this is not application integrations, this is whole chirpstack backend integration.
each app has own integration(s), which you can configure via web UI or REST API

#3

I do not see mqtt and postgresql integration via API or web interface. How can I connect them exactly?

#4

MQTT and PostgreSQL integration available in chirpstack-application-server.toml configuration file

# Enabled integrations.
  #
  # Enabled integrations are enabled for all applications. Multiple
  # integrations can be configured.
  # Do not forget to configure the related configuration section below for
  # the enabled integrations. Integrations that can be enabled are:
  # * mqtt              - MQTT broker
  # * amqp              - AMQP / RabbitMQ
  # * aws_sns           - AWS Simple Notification Service (SNS)
  # * azure_service_bus - Azure Service-Bus
  # * gcp_pub_sub       - Google Cloud Pub/Sub
  # * kafka             - Kafka distributed streaming platform
  # * postgresql        - PostgreSQL database
  enabled=["mqtt"]


  # MQTT integration backend.
  [application_server.integration.mqtt]
  # Event topic template.
  event_topic_template="application/{{ .ApplicationID }}/device/{{ .DevEUI }}/event/{{ .EventType }}"

  # Command topic template.
  command_topic_template="application/{{ .ApplicationID }}/device/{{ .DevEUI }}/command/{{ .CommandType }}"

  # Retain events.
  #
  # The MQTT broker will store the last publised message, when retain events is set
  # to true. When a MQTT client connects and subscribes, it will always receive the
  # last published message.
  retain_events=false

  # MQTT server (e.g. scheme://host:port where scheme is tcp, ssl or ws)
  server="tcp://localhost:1883"

  # Connect with the given username (optional)
  username=""

  # Connect with the given password (optional)
  password=""

  # Maximum interval that will be waited between reconnection attempts when connection is lost.
  # Valid units are 'ms', 's', 'm', 'h'. Note that these values can be combined, e.g. '24h30m15s'.
  max_reconnect_interval="1m0s"

PostgreSQL integration

# PostgreSQL database integration.
  [application_server.integration.postgresql]
  # PostgreSQL dsn (e.g.: postgres://user:password@hostname/database?sslmode=disable).
  dsn=""

  # This sets the max. number of open connections that are allowed in the
  # PostgreSQL connection pool (0 = unlimited).
  max_open_connections=0

  # Max idle connections.
  #
  # This sets the max. number of idle connections in the PostgreSQL connection
  # pool (0 = no idle connections are retained).
  max_idle_connections=2
#5

This will set up for all mqtt and postgresql.
