Lmanage can be found on pypi.

pip install lmanage

How do I Use it.

Commands

LManage will ultimately will have many different commands as development continues

Status	Command	Rationale
Live	mapview	Find the LookML fields and tables that are associated with a piece of Looker content
Planned	removeuser	Based on last time logged in, prune Looker users to ensure a performant, compliant Looker instance
Planned	dcontent	Iterate through an input of content, delete content and back it up using gzr for easy restoration
Planned	bcontent	Iterate through all broken content (using content validator) and email a customized message to each dashboard owner
Planned	scoper	Takes in a model file, elminates the * includes, iterate through the explores and joins and creates a fully scoped model include list for validation performance and best practice code organization

help and version

Usage: lmanage [OPTIONS] COMMAND [ARGS]...

Commands:
  mapview

mapview

The mapview command will find the etymology of the content on your dashboard, exporting a CSV that looks like this.

example usage

lmanage mapview --path ./output/my_output.csv --ini-file ~/py/projects/ini/k8.ini --project /test_lookml_files/the_look -table "order_items"

flags

• path (--path, -fp) This is the path where you would like the outputfile for your returned dataset to be.
• ini-file (--ini-file, -i) This is the file path to the ini file that you've created to use the Looker SDK

#example Ini file
[Looker_Instance]
base_url=https://looker-dev.company.com:19999 (or 443 if hosted in GCP)
client_id=abc
client_secret=xyz
verify_ssl=True

• project (--project, -p) This is the file path to your local project of LookML files that lmanage will scan to associate connections between your Looker content and LookML Lmanage can either return a full dataset of all content mapping, or a prefiltered dataset with all content associated with a specific table or field.
• table (--table, -t) Optional Expecting input of lookml view name
• field (--field, -f) Optional Expecting input of fully scoped LookML field name e.g. viewname.fieldname

Fields Returneds

• dashboard_id: the id of the looker dashboard
• element_id: the id of the visualization element on the looker dashboard
• sql_joins: the joins used in a query grouped by element id
• fields_used: the fields used by the query grouped by element id
• sql_table_name: the underlying sql value being referenced at the view level of the lookml (assuming the view is standard)
• potential_join: for the explore that powers the element query: what are all the potential joins available
• used_joins: joins used by the underlying queries obtained by parsing sql of query
• used_view_names: views that are used by each query grouped by element_id
• unused_joins: views that are unused by the specific query of the dashboard element

n.b.

Multi Project Usage Dashboards can hold tiles from multiple projects, in this case if you create one local folder of lookml see example below, then pass the value of that one meta folder the the --project flag. Doing this will enable the underlying LookML parsing engine driven by pyLookML to iterate over all the relevant files and find the appropriate cross project matches.
