## Prérequis {#prerequisites}

* Installer [`etcd` et `etcdctl`](/fr/docs/etcd/install/)

## Vérifier l'état global {#check-overall-status}

`endpoint status` pour vérifier l'état global de chaque point de terminaison spécifié dans le drapeau `--endpoints` :

```bash
etcdctl endpoint status (--endpoints=$ENDPOINTS|--cluster)
```

### Options {#options}

```bash
--cluster[=false]: use all endpoints from the cluster member list
```

## Vérifier l'état de santé {#check-health}

`endpoint health` pour vérifier l'état de santé de chaque point de terminaison spécifié dans le drapeau `--endpoints` :

```bash
etcdctl endpoint health (--endpoints=$ENDPOINTS|--cluster)
```

### Options {#options-1}

```bash
--cluster[=false]: use all endpoints from the cluster member list
```

## Vérifier le hachage KV {#check-kv-hash}

`endpoint hashkv` pour vérifier le hachage de l'historique des paires clé-valeur de chaque point de terminaison spécifié dans le drapeau `--endpoints` :

```bash
etcdctl endpoint hashkv (--endpoints=$ENDPOINTS|--cluster) [rev=$REV]
```

### Options {#options-2}

```bash
--cluster[=false]: use all endpoints from the cluster member list
--rev=0: maximum revision to hash (default: latest revision)
```

## Options héritées des commandes parentes {#options-inherited-from-parent-commands}

```bash
--endpoints="127.0.0.1:2379": gRPC endpoints
-w, --write-out="simple": set the output format (fields, json, protobuf, simple, table)
```

### Exemples {#examples}

```shell
etcdctl --write-out=table --endpoints=$ENDPOINTS endpoint status
