How is Lucene instances determined?

[YuWatanabe]

Hello

I have a question with monitoring. How are number of Lucene instances determined? I only have 1 node but I see 3 in my case.

My environment is elasticsearch 5.3.0 and basic information is below.

curl -XGET 127.0.0.1:9200/_cat/health?v
epoch      timestamp cluster       status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
1491884683 13:24:43  elasticsearch yellow          1         1     84  84    0    0       84             0                  -                 50.0%

Hi @YuWatanabe,

if you look at the legend of the three charts, you can see that they each displays a different set of memory metrics about the same index. Those are not meant to show three distinct indices.

Your right . My apology for asking you a silly question and wasting your time.

All the legends are different.
