Hello experts, I have a new logstash cluster running with below versions: - elasticsearch = "0.90.9" - logstash = "1.3.3" - Java version = "1.6.0\_45" - nodes -\> 4 nodes [VM's] [log002(nxlog server, logstash server and elasticsearch node), 003,004,005 (elasticsearch nodes)]. My nxlog conf - [http://pastebin.com/A0H9rwT8](http://pastebin.com/A0H9rwT8) my logstash conf - [http://pastebin.com/UAj1k6K4](http://pastebin.com/UAj1k6K4) There are couple of problems: 1. log002 seems registered as two nodes one is as log002 and other is as Glitch [The name changes everytime I restart logstash server]. There are continuous lines in elasticsearch logs from all the nodes [the below is from log003]: Glitch log002.utils log003.utils log004.utils log005.utils --\> as seen from elasticsearch head [2014-02-12 22:57:14,930][WARN][discovery.zen] [log003.utils] received a join request for an existing node [[Glitch][6Vi1Np4ETXG1GRHIaR0z9A][inet[/10.10.0.3:9300]]{client=true, data=false}] [2014-02-12 22:57:59,961][WARN][discovery.zen] [log003.utils] received a join request for an existing node [[Glitch][6Vi1Np4ETXG1GRHIaR0z9A][inet[/10.10.0.3:9300]]{client=true, data=false}] [2014-02-12 22:58:44,993][WARN][discovery.zen] [log003.utils] received a join request for an existing node [[Glitch][6Vi1Np4ETXG1GRHIaR0z9A][inet[/10.10.0.3:9300]]{client=true, data=false}] [2014-02-12 22:59:30,035][WARN][discovery.zen] [log003.utils] received a join request for an existing node [[Glitch][6Vi1Np4ETXG1GRHIaR0z9A][inet[/10.10.0.3:9300]]{client=true, data=false}] 1. I'm getting a \_jsonparsefailure in all the messages I see in kibana. Can you please suggest what is wrong ? {"@source":"tcp://127.0.0.1:54427/","@tags":["\_jsonparsefailure"],"@fields":{},"@timestamp":"2014-02-12T23:02:47.134Z","@source\_host":"127.0.0.1","@source\_path":"/","@message":"sourceFile\u0002\u0001\u0011\u0000\u0000\u0000/var/log/user.log\u0013\u0000SyslogFacilityValue\u0001\u0001\u0001\u0000\u000... ---
