Documentation Grafana Agent Static mode Cookbook Dynamic Configuration Structure

01 Structure

Dynamic Configuration uses a series of files to load templates. This example will show how they all combine together. Running the below command will combine all the templates into the final.yml. Any failure while loading the config will revert to the original config, or if this is the initial load Grafana Agent will quit.

docker run -v ${PWD}/:/etc/grafana grafana/agentctl:latest template-parse file:///etc/grafana/01_config.yml

Dynamic Configuration

config.yml

yaml Copy

template_paths:
  - "file:///etc/grafana/01_assets"

Tells the Grafana Agent where to load files from. It is important to note that dynamic configuration does NOT traverse directories. It will look at the directory specified only, if you need more directories then add them to the template_paths array. NOTE, if no protocol specified ie file:// above, then file access will be assumed. file:///etc/grafana/01_assets is equivalent to //etc/grafana/01_assets

Agent

Dynamic Configuration will find the first file matching pattern agent-*.yml and load that as the base. You can only have one agent template. If multiple matching templates are found then the configuration will fail to load.

agent-1.yml

yaml Copy

server:
  log_level: debug
metrics:
  wal_directory: /tmp/grafana-agent-normal
  global:
    scrape_interval: 60s
    remote_write:
      - url: https://prometheus-us-central1.grafana.net/api/prom/push
        basic_auth:
          username: xyz
          password: secretpassword
integrations:
  node_exporter:
    enabled: true
  agent:
    enabled: true

Server

Dynamic configuration will find the first file matching pattern server-*.yml and replace the Server config block in the Agent Configuration. Note that you do NOT include the server: tag, dynamic configuration knows by the name that it is a configuration block.

You can only have 1 server template.

server-1.yml

yaml Copy

log_level: info

Final

final.yml

In the above example the log_level: debug block will be replaced with log_level: info from the server-1.yml
