Hi Team, Kindly suggest any solutions for below errors. Our cluster is in Red state due to this: 2018-10-05T01:30:58,403][WARN][o.e.m.j.JvmGcMonitorService] [Node\_ELK] [gc][young][1301721][238872] duration [2.2s], collections [1]/[2.4s], total [2.2s]/[2.5h], memory [8.8gb]-\>[8.7gb]/[11.9gb], all\_pools {[young] [182.3mb]-\>[6.3mb]/[266.2mb]}{[survivor] [33.2mb]-\>[28mb]/[33.2mb]}{[old] [8.6gb]-\>[8.6gb]/[11.6gb]} Thanks, Gayathri T R ---

It looks like you either need to reduce heap usage or scale up/out the cluster to increase the amount of available heap. ---

Can you please suggest any method for that. We have already deleted many of the old indices also added below entry in jvm.options file: -Xms12g -Xmx12g Still the cluster is in RED state. ---

What is the full output of the [cluster stats API](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-stats.html)? ---
