recently elasticsearch stops sending data to kibana as the disk space is exceeded.per day i can see 5 M documents are flowing from other server to Elasticsearch.Please find the error am getting
[2017-08-31T01:21:49,851][WARN ][o.e.c.r.a.DiskThresholdMonitor] [production] high disk watermark [90%] exceeded on [8klVIR6LQfOxAUcELG3wtA][production][/var/lib/elasticsearch/nodes/0] free: 20kb[2.8E-5%], shards will be relocated away from this node
could any one please suggest how can i avoid this issue?
I have tried to update the heap memory form xms2g to xms16g. still elasticsearch is not working.
Can anyone tell me where json documents actually stored?
Thanks in Advance !!!!!
