# Monitorar com Grafana Cloud

Este guia ajudará você a configurar o monitoramento para seus clientes Wingbits usando o Grafana Cloud.

## Pré-requisitos

* Uma conta Grafana Cloud (camada gratuita disponível em [grafana.com](https://grafana.com))

## Passo 1: Instalar o Grafana Alloy

O Grafana Alloy é um coletor que reunirá métricas dos seus clientes Wingbits.

1. Vá para https\://{sua-conta-grafana}.grafana.net/a/grafana-collector-app/alloy
2. Siga as instruções de instalação
3. Habilite Configuração Remota durante a configuração

## Passo 2: Configurar Coleta de Métricas

1. Aguarde alguns minutos para o seu servidor aparecer em *Collector->Fleet Management*
2. Selecione *Configuração Remota* e clique *Criar Pipeline de Configuração*
3. Escolha *Configuração Personalizada*
4. Cole esta configuração (substitua os IPs pelos seus clientes Wingbits):

```yaml
prometheus.scrape "wingbits_hosts" {
    targets = [
        {__address__ = "192.168.10.1:8088", alias = "station1"},
        {__address__ = "192.168.10.2:8088", alias = "station2"},
    ]
    forward_to = [prometheus.remote_write.default.receiver]
}

prometheus.remote_write "default" {
    endpoint {
        url = sys.env("GCLOUD_HOSTED_METRICS_URL")
        basic_auth {
            username = sys.env("GCLOUD_HOSTED_METRICS_ID")
            password = sys.env("GCLOUD_RW_API_KEY")
        }
    }
}
```

5. Clique *Testar Pipeline de Configuração*
6. Selecione atributos correspondentes (por exemplo, os=linux)
7. Salve a configuração

## Passo 3: Criar Dashboard

1. Vá para Dashboards → *Novo → Importar*
2. Cole o JSON do dashboard abaixo
3. Salve e visualize suas métricas

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.wingbits.com/wingbits/wingbits-english-pt-br/comece-aqui/monitor-with-grafana-cloud.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
