i have my ELK cluster working fine, but i would like to get rid of some error messages found in the log file.
one of them is this one:
2016-06-30 22:21:25,815[INFO ][discovery.zen ] [elastic-node-202-174] master_left [{elastic-node-30-161}{5WrNrcy-VygOw}{192.168.30.161}{192.168.30.161:9300}], reason [failed to ping, tried [3] times, each with maximum [30s] timeout]
i know that my company firewall is blocking icmp reply (we can't ping servers in different networks).
so, what config should i change make this message go away?
The pinging done by ES is not based on ICMP but uses the same protocol as for all other kinds of inter-node communication (TCP). The log warning indicates that the master node was not reachable from this node for 90 seconds. Maybe the master was down for a while or there are connection issues in your network?
