Bonjour,

Je cherche à faire un split d'un document Json sur le premier champ.  
J'essaie d'utiliser le filtre "alter" mais j'obtiens l'erreur suivante:

```auto
Cannot create pipeline {:reason=>"Couldn't find any filter plugin named 'alter'. Are you sure this is correct? Trying to load the alter filter plugin resulted in this error: Problems loading the requested plugin named alter of type filter. Error: NameError NameError"}

```

Est-ce que "alter" existe encore ou a été fusionné avec "mutate" comme il était prévu que ce soit fait?

Je ne connais pas alter. Mais mutate en effet existe.

[alter filter plugin](https://www.elastic.co/guide/en/logstash/current/plugins-filters-alter.html)

il est pourtant bien présent dans la liste des filtres de Logstash 🤔

J'ai essayé aussi "mutate" avec "split" mais il ne fonctionne pas.

```auto
	mutate {	convert => { "[message]" => "string" } }
	split { field => "message" }

```

Je n'arrive toujours pas à diviser mon document JSON en plusieurs éléments (array ou autre)

Dans la doc, il est décrit comment l'installer. Tu l'as fait ?

J'ai un doute avec le message de succès vu le message juste avant...

@colinsurprenant ton avis ?

quand j'affiche la liste des filtres avec la commande: bin/logstash-plugin list, il s'affiche bien

 ![alter](https://us1.discourse-cdn.com/elastic/original/3X/d/9/d9e7b6664d49b39249579dfb9575f61dd46d99af.png)
