Segments count и Heap size

[rusty]

Привет, папки с индексами можно не перемещать, достаточно закрыть "ненужные" индексы. Сегментов действительно много, но надо смотреть что показывает статистика по ноде:

ELK suddenly colapsed

You can also can close unused indexes (their data become unavailable, but it would free up the memory) Run curl -XGET "localhost:9200/_stats?pretty" and get a look at all - segments - memory_in_bytes. Divide memory_in_bytes by number of nodes and you'll get rough estimation of memory consumption on each node. For more details, please, follow these links: topic1, topic2

и хороший коммент про минусы закрытия индексов:

Don't do that unless you have to though: closed indices are no longer managed by ES. Meaning if a node dies with closed index shards, they will not be recovered elsewhere. Say you close an index for 2 months and you had 2 node failures in that time .. it could just be that both primary and replica shard X were discarded and never recovered. You try to open the index one day and voila: it's Red and you lost data. Just saying
