Hello, I have a question. I have installed elasticsearch on azure. OS is Ubuntu. And look up the cpu usage. I ran '\_cat/nodes?format=json' , and the cpu value is -1. can not understand. I browsed the documentation ([Get node statistics | Elasticsearch API documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-stats.html)) ## (integer) Recent CPU usage for the whole system, or -1 if not supported. In what cases is this not supported? please answer about my question. thank you. ---

I'll document how I solved it. It was resolved by changing AdoptOpenJDK to MS OpenJDK and restarting elasticsearch. My guess is that it's an issue with using azure and AdoptOpenJDK. ---
