I don't know why the Elasticsearch is not healthy, i've recently created this VM to install as a new cluster node, but can't install. Can anyone help me?

Hi @Pedroka 

May be curl <ip_address>:9200/_cluster/health and the information from ElasticSearch documentation will help you to solve your question.

But before operate any fixing to the ELK I would consult first with support

Hi @Pedroka 

  • Make sure you have su or sudo permissions to execute the fetched commands from the cmc.
  • check the below concerns are met.
  • revisit the created log files "/var/log/dynatrace/install.log", "/opt/dynatrace-managed/installer/" after the unsuccessful installation to pinpoint to the main root cause.
  • make sure that NTP synchronization is configured properly on the target cluster nodes, latency is less 10 ms, and these cluster nodes are in the same data center.
