 We need just few things! 
 
-Central **Galaxy Job Radar** instance is running on the server at CESNET in Czech Republic. It takes data from each connected **Galaxy Server**. Each Galaxy server has its own **Galaxy database** and they also have their own **InfluxDB** database. GJR goes over InfluxDBs of connected Galaxy servers and requests them for new data periodically. Because of this, we need every Galaxy admin to set up his InfluxDB, fill it periodically with new data with [gxadmin scripts](https://github.com/usegalaxy-eu/infrastructure-playbook/tree/master/roles/usegalaxy-eu.job-radar-stats-influxdb/files) and give us credentials to this database.

On how to setup InfluxDB and Telegraf app for your Galaxy server you can follow up here: [https://training.galaxyproject.org/training-material/topics/admin/tutorials/monitoring/slides-plain.html](https://training.galaxyproject.org/training-material/topics/admin/tutorials/monitoring/slides-plain.html). Telegraf is the tool, which can run your gxadmin scripts periodically and fill the Influx DB with obtained data. Gxadmin scripts that you will need you can find [here](https://github.com/usegalaxy-eu/infrastructure-playbook/tree/master/roles/usegalaxy-eu.job-radar-stats-influxdb/files). With the tutorial mentioned above you can learn how to setup Telegraf so it will use mentioned gxadmin scripts.
