 # Using netdata with Prometheus
 
+> IMPORTANT: the format netdata sends metrics to prometheus has changed since netdata v1.7. The new prometheus backend for netdata supports a lot more features and is aligned to the development of the rest of the netdata backends.

 Prometheus is a distributed monitoring system which offers a very simple setup along with a robust data model. Recently netdata added support for Prometheus. I'm going to quickly show you how to install both netdata and prometheus on the same server. We can then use grafana pointed at Prometheus to obtain long term metrics netdata offers. I'm assuming we are starting at a fresh ubuntu shell (whether you'd like to follow along in a VM or a cloud instance is up to you).

 ### Installing Prometheus
+
 In order to install prometheus we are going to introduce our own systemd startup script along with an example of prometheus.yaml configuration. Prometheus needs to be pointed to your server at a specific target url for it to scrape netdata's api. Prometheus is always a pull model meaning netdata is the passive client within this architecture. Prometheus always initiates the connection with netdata.

 The following is completely optional, it will enable Prometheus to generate alerts from some NetData sources. Tweak the values to your own needs. We will use the following `nodes.yml` file below.

This is the most preferred method by prometheus, but it is also the harder to work with. To work with this data source, you will need to understand how to get meaningful values out of them.

+### Accuracy of `average` and `sum` data sources
 
 When the data source is set to `average` or `sum`, netdata remembers the last access of each client accessing prometheus metrics and uses this last access time to respond with the `average` or `sum` of all the entries in the database since that. This means that prometheus servers are not losing data when they access netdata with data source = `average` or `sum`.
