# PrometheusPhoenix [](https://hex.pm/packages/prometheus_phoenix) [](https://travis-ci.org/deadtrickster/prometheus-phoenix)
## Metrics
- `phoenix_controller_call_duration_microseconds` - Whole controller pipeline execution time.
Labels:
- `:controller`
- `:action`
- `:method`
- `:scheme`
- `:host`
- `:port`
## Configuration
This integartion is configured via PhoenixInstrumenter :prometheus app env key
Default configuration:
``` elixir
config :prometheus, PhoenixInstrumenter,
labels: [:controller, :action],
duration_buckets: [10, 100, 1_000, 10_000, 100_000, 300_000,
500_000, 750_000, 1_000_000, 1_500_000,
2_000_000, 3_000_000]
```
Duration units are microseconds. You can find more on what stages are available and their description [here](https://hexdocs.pm/ecto/Ecto.LogEntry.html).
With this configuration scrape will look like this:
```

## Installation
[Available in Hex](https://hex.pm/packages/prometheus_phoenix/), the package can be installed as:
1. Add `prometheus_phoenix` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:prometheus_phoenix, "~> 0.0.4"}]
end
```
2. Ensure `prometheus_phoenix` is started before your application:
```elixir
def application do
[applications: [:prometheus_phoenix]]
end
```
