ES version: 6.3.0 My ES cluster block sometimes when perform search and bulk operations, but the cluster status is green, it is strange. The `cat.thread_pool` api can output some related info, but i do not know how to determine the abnormal status. ```auto node_name name active queue rejected m-21-63 analyze 0 0 0 m-21-63 fetch_shard_started 0 0 0 m-21-63 fetch_shard_store 0 0 0 m-21-63 flush 0 0 0 m-21-63 force_merge 0 0 0 m-21-63 generic 1 0 0 m-21-63 get 0 0 0 m-21-63 index 0 0 0 m-21-63 listener 0 0 0 m-21-63 management 1 0 0 m-21-63 ml_autodetect 0 0 0 m-21-63 ml_datafeed 0 0 0 m-21-63 ml_utility 0 0 0 m-21-63 refresh 0 0 0 m-21-63 rollup_indexing 0 0 0 m-21-63 search 1 0 1946236 m-21-63 security-token-key 0 0 0 m-21-63 snapshot 0 0 0 m-21-63 warmer 0 0 0 m-21-63 watcher 0 0 0 m-21-63 write 0 0 12383 ``` Is there a proper way to get or compute the performance information? ---

Do you have Monitoring enabled? ---

Yes, i can see the monitor page. ---

What does it show when this behaviour happens? High GC, threadpool use, memory/CPU use? ---

I just can see the cup/memory/disk and search/index rate. ![image](https://us1.discourse-cdn.com/elastic/original/3X/3/c/3c570b4b72eb30564f7eefced162b1f25861f306.png) Where is the GC and thread pool info? ---

Maybe I can not see these info because the basic license? ---

My ES and Kibana version is 6.3.0, and I do not use metric beat. I have two cluster, and I have compare the two versions, 6.3 and 7.11, there is no GC and thread pool info both of them. Did I miss anything? ---

6.3 has been [EOL](https://www.elastic.co/support/eol) for quite some time, you should upgrade ASAP. In 7.11 you need to go to Stack Monitoring \> choose your cluster \> Nodes \> pick your node, then you will see GC. ---

Thanks a lot. I find the GC graph. And how do I get the thread pool info and something else about performance...by an API? ---
