I am using below query to check health of ES cluster.
name version port load ram.max ram.current ram.percent heap.max heap.current heap.percent uptime file_desc.max file_desc.percent refresh.time segments.count data-node-1 1.5.2 9300 0.70 31.5gb 31.1gb 61 15.9gb 8.9gb 55 9.7d 65535 86 7.2h 28012 data-node-3 1.5.2 9300 1.14 31.3gb 31gb 60 15.9gb 6.9gb 43 6.1d 65535 86 4.9h 27998 data-node-2 1.5.2 9300 0.52 31.3gb 30.9gb 60 15.9gb 10.7gb 67 6.1d 65535 86 4h 28062
Can you please let u know, what parameter should I improve and how?
- I frequently get too many open files error and cluster shuts down after that.
Now there are 86 percent open files? I fear this figure will increase and it will go down,
- Heap allocated is 16 GB. Why does it shows ram.percent as 61? it should be 50%
- What is segment count? Does it matter for the performance? how to improve this factor?
