A Gleam client library for [Prometheus](https://prometheus.io) with a focus on simplicity. Currently heavily WIP.

```sh
gleam add observatory
```
```gleam
import observatory

const http_status_200_metric = "http_total_status_200"
const search_total_items_returned_metric = "search_total_items_returned"

pub fn main() {
    let observatory = observatory.init()
    |> observatory.counter_init(http_status_200_metric)
    |> observatory.counter_init(search_total_items_returned_metric)
    
    // Some code here...
    
    observatory.counter_inc(http_status_200_metric)
    observatory.counter_inc_by(
      search_total_items_returned_metric, 
      returned_items_count
    )
}
```
