The "Objects" column (2nd column) shows the total number of instances for that class/package, and the retained size shows the size of that class and all of its members. There are thus 70,000 `TransportReplicationAction$ReroutePhase` , and their total size is ~15.6 GB. ![48%20PM](https://us1.discourse-cdn.com/elastic/original/3X/7/e/7e6da558531102e2a97663e1664a43d4fa4e6d02.png) There are also 22,000 bulk requests: ![53%20PM](https://us1.discourse-cdn.com/elastic/original/3X/a/0/a0b0ccba2d3fe1abb240b74088278b7b107fb78d.png) 3.8 million index requests: ![08%20PM](https://us1.discourse-cdn.com/elastic/original/3X/e/b/eb5ef45b995337dbb9d2f89d1b5a5352317208f0.png) Here is an example document: ![16%20PM](https://us1.discourse-cdn.com/elastic/original/3X/2/6/26926c38c23e2dfa53b421a7bb58421788d9b3b9.png) However, my `thread_pool.bulk.queue_size` is only 50 for that node. Additional info: 46 ingest/hot nodes 46 Logstash instances `thread_pool.bulk.queue_size: 50` `thread_pool.bulk.size: 17` batch size for ES publish is 200 documents per request. Each Logstash has 72 threads available for publishing. ---
