Configure Grafana

Please take these steps to create an API key with your Grafana instance:

• Go to https://daq.example.org/grafana/org/apikeys.
• Choose "New API Key".
  • Key name: grafana-wtf
  • Role: Admin
• From the output curl -H "Authorization: Bearer eyJrIjoiWHg...dGJpZCI6MX0=" ..., please take note of the Bearer token. This is your Grafana API key.

Configuration

Grafana connection

To configure to which Grafana instance to connect to, and how to authenticate, use the --grafana-url and --grafana-token command line options.

Alternatively, before running grafana-wtf, you can define URL and access token of your Grafana instance by using environment variables:

export GRAFANA_URL=https://daq.example.org/grafana/
export GRAFANA_TOKEN=eyJrIjoiWHg...dGJpZCI6MX0=

In order to accept untrusted SSL certificates, append the ?verify=no query string to the GRAFANA_URL:

export GRAFANA_URL=https://daq.example.org/grafana/?verify=no

Caching

grafana-wtf will cache HTTP responses for 60 minutes by default, in order to save resources, by not hitting the server each server. You can configure that setting by using the --cache-ttl option, or the CACHE_TTL environment variable.

When invoking the program with the --drop-cache option, it will drop its cache upfront.

How to find dashboards using specific data sources?

# Display all dashboards which use a specific data source, filtered by data source name.
grafana-wtf explore dashboards --format=json | jq '.[] | select(.datasources | .[].type=="<datasource_name>")'

# Display all dashboards using data sources with a specific type. Here: InfluxDB.
grafana-wtf explore dashboards --format=json | jq '.[] | select(.datasources | .[].type=="influxdb")'

How to list all queries used in all dashboards?
