How do I configure Loki for my logging needs?

To configure Loki, you'll need to set up a configuration file. Do you have a specific environment in mind?

Yes, I'm using Docker for deployment.

Great! You can use the following configuration in your loki-config.yaml file for Docker:

server:
  http:
    port: 3100

positions:
  filename: /tmp/loki-positions.yaml

clients:
  - url: http://<your-promtail>:3101/loki/api/v1/push

scrape_configs:
  - job_name: syslog
    static_configs:
      - targets:
          - localhost
        labels:
          job: syslog
          __path__: /var/log/syslog

Make sure to replace <your-promtail> with the actual address of your Promtail instance.

What about the Promtail configuration?

For Promtail, you can use a similar configuration. Here's an example:

server:
  http:
    port: 9080

positions:
  filename: /tmp/positions.yaml

clients:
  - url: http://<your-loki>:3100/loki/api/v1/push

scrape_configs:
  - job_name: varlogs
    static_configs:
      - targets:
          - localhost
        labels:
          job: varlogs
          __path__: /var/log/*log

Again, replace <your-loki> with your Loki instance address.

Thanks! How do I verify that Loki is receiving logs?

You can verify that Loki is receiving logs by querying it through Grafana or using the Loki API. Would you like to know how to set that up?
