I have all my servers pushing syslog data to 4 logstash servers, the logstash servers are not forwarding syslog information into elasticsearch, here is my conf file

input {  
tcp {  
port =\> 5514  
type =\> syslog  
}  
udp {  
port =\> 5514  
type =\> syslog  
}  
}

filter {  
if ([message] =~ "LTM UDP Check") {  
drop {}  
}  
if ([message] =~ "nrpe") {  
drop {}  
}  
}

filter {  
if [type] == "syslog" {  
grok {  
match =\> { "message" =\> "%{SYSLOGTIMESTAMP:syslog\_timestamp} %{SYSLOGHOST:syslog\_hostname} %{DATA:syslog\_program}(?:[% {POSINT:syslog\_pid}])?: %{GREEDYDATA:syslog\_message}" }  
add\_field =\> ["received\_at", "%{@timestamp}"]  
add\_field =\> ["received\_from", "%{host}"]  
}  
date {  
match =\> ["syslog\_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]  
}  
}  
}

output {  
if [type] == "syslog" {  
elasticsearch { hosts =\> ["us5lpvinfelk001:9200"] }  
stdout { codec =\> rubydebug }  
}  
}
