 GrimoireELK is the component of [GrimoireLab](https://github.com/chaoss/grimoirelab) that interacts with the ElasticSearch database. Its goal is two-fold, first it aims at offering a convenient
 way to store the data coming from Perceval, second it processes and enriches the data in a format that can be consumed by Kibiter.

 In order to run them, you need to have in your machine instances (or Docker containers) of ElasticSearch and MySQL

   - in case you are using non-default credentials for your SortingHat database, you will need to include the `[Database]` section of the file with both `user` and `password` parameters
 - create the databases `test_sh` and `test_projects` in your MySQL instance (e.g., `mysql -u root -e "create database test_sh"`, if you are running mysql in a container use `docker exec -i <container id> mysql -u root -e "create database test_sh"`)
-- populate the database `test_projects` with the SQL file [test_projects.sql](https://github.com/chaoss/grimoirelab-elk/blob/master/tests/test_projects.sql) (e.g., `mysql -u root test_projects < tests/test_projects.sql`)
