Hi All  
I would like to separate my Prometheus data source into different distinct data sources based on the metrics in Prometheus for example:  
Prometheus-RabbirMQ --\> will filter only metrics starting with RabbitMQ  
Prometheus-Elasticsearch --\> will filter only metrics starting with Elasticsearch

Is it possible to reach such granularity ?

Hi @mormor83,

any particular reason why you want to do that split at data source level? I have usually wanted to include more data per data source instead of sharding it there.  
Just curious 🙂

Hi,

I would like this aswell. My reason for this is, that we have multible HAProxy Clusters. I would like to seperate does in grafana.

I am a new user and I dont know prometheus and grafana that well. So if there is another way, I would love to hear this.

Hi @b0b  
This is to separate it to different users using the grafana enterprise license ( datasource permission) Not all teams uses Elastic and i would like to “give” the ones that do that datasource.  
Is it possible?

With PromQL you can easily filter on any tags and make them variables for a dashboard.

For the OT  
How to split a data source, now that is something else. It _might_ be possible using _Custom Query Parameters_ but I have not tried doing anything like that.
