We are running es 1.2.1 cluster on 4 nodes: 4 cores, 14 GB RAM, 1.5 TB disk
space, swap disabled.
Our application creates daily indexes 2 up to 12 GB in size. No sharding, 1
replica. Currently 200+ indexes (~1.2 TB data). Heap size is set to 6 GB.
The main problem is that elastic nodes frequentely (once a day or two) eats
up whole system memory and dies. Now it is monitored with monit with
setting to restart node on 90% memory usage. It still fails from time to
Adding new nodes is currently very difficult, so I'm looking for a way to
optimize my current setup. Any suggestions?
