# SLO CUE

Generate Prometheus alerting & recording rules for SLOs with CUE.

__Highly experimental!__

## Usage

First, a service must be defined with associated SLOs.

```cue

import (

	"github.com/cbrgm/slo-cue/schema"

)

services: schema.#ServiceDefinition

services: "foo_service": [

	{

		name:        "read"

		errorsQuery: "sum(rate(promhttp_metric_handler_requests_total{namespace='default',job='fooapp',code=~'5..'}[$__range]))"

		totalQuery:  "sum(rate(promhttp_metric_handler_requests_total{namespace='default',job='fooapp'}[$__range]))"

		threshold:   0.999

	}

]

```

This service definition must be saved in the `tools` folder (for example as `foo_service.cue`). 

Dump the [Prometheus](https://prometheus.io) Alerting & Recording Rules as JSON.

```

cd tools && cue dumpjson

```

or as yaml

```

cd tools && cue dump

```
