Graylog master is down because of heap reached 8GB , only data node is running with same heap size 8GB . Output buffer is reached 100% datanote processing 109 messages in past 5 minutes. I am using 1master and 2 datanode in my elastic setup .
Below is my elastic config:
2 master nodes with 2GB memory, i core cpu, 2 data nodes with 4GB memory and 1 core CPU.
Below is last 1 hr elasticsearch status.
