Setup

Install grafana-wtf

::

pip install grafana-wtf

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.

Usage

::

# Display a bunch of meta information and statistics.
grafana-wtf info --format=yaml

# Display Grafana version.
grafana-wtf info --format=json | jq -r '.grafana.version'

Explore data sources

How to find unused data sources? ::

# Display all data sources and the dashboards using them, as well as unused data sources.
grafana-wtf explore datasources --format=yaml

# Display names of unused datasources as a flat list.
grafana-wtf explore datasources --format=json | jq -r '.unused[].datasource.name'

Explore dashboards

How to find dashboards which use non-existing data sources? ::

# Display some details of all dashboards, including names of missing data sources.
grafana-wtf explore dashboards --format=yaml

# Display only dashboards which have missing data sources, along with their names.
grafana-wtf explore dashboards --format=json | \
    jq '.[] | select(.datasources_missing) | .dashboard + {ds_missing: .datasources_missing[] | [.name]}'

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? ::

grafana-wtf explore dashboards --data-details --queries-only --format=json | \
    jq '.[].details | values[] | .[] | .expr,.jql,.query,.rawSql | select( . != null and . != "" )'

Searching for strings

Find the string weatherbase throughout all dashboards and data sources::

grafana-wtf find weatherbase

Replacing strings

Replace all occurrences of ldi_v2 with ldi_v3 within dashboard with UID _JJ22OZZk::

grafana-wtf --select-dashboard=_JJ22OZZk replace ldi_v2 ldi_v3

In order to preview the changes, you should use the --dry-run option beforehand::

grafana-wtf --select-dashboard=_JJ22OZZk replace ldi_v2 ldi_v3 --dry-run
