Introdução
Para quem não conhece, o Elasticsearch é um “servidor de buscas distribuído baseado no Apache Lucene”. Em outras palavras, pode-se dizer que o Elasticsearch é um banco de dados NoSQL, porém com esteroides, uma série de plugins e ferramentas auxiliares. E o melhor, opensource.
Abaixo está uma lista de comandos que podem ajudar na execução de solução de problemas do seu cluster elasticsearch.
substitua localhost pelo endereço IP de seus hosts elasticsearch se não estiver escutando em localhost.
