Example: Loki

Loki Logging

paStash can be used to easily ship logs to Grafana Loki or cLoki

Setup

Install paStash next-gen and the Loki output plugin globally using npm:

# npm install -g @pastash/pastash @pastash/output_loki

Recipe

In this super simple recipe we'll use the file input and loki output

input {
  file {
    path => "/var/log/*.log"
  }
}

output {
  loki {
    host => localhost
    port => 3100
    path => "/loki/api/v1/push"
  }
}

Grafana Hosted

When using the Grafana Hosted Loki, use this format as template:

input {
  file {
    path => "/var/log/*.log"
  }
}

output {
  loki {
    basic_auth_password => "some_very_secure_password_hash_here"
    basic_auth_user => "1234"
    host => "logs-us-west1.grafana.net"
    port => 80
    path => "/api/prom/push"
  }
}

Once ready, save to your preferred location (ie: /etc/pastash_loki.json)

Usage

./bin/pastash --config_file=/etc/pastash_loki.json

Docker

For those using Docker there's a ready to go container for Loki output

pastash:
    image: qxip/pastash-loki
    container_name: pastash
    volumes:
      - ./conf/pastash_loki.json:/pastash.conf
      - /var/log:/var/log:ro
