I am trying to send information from a logfile to elasticsearch using logstash. I cant seem to find the solution to this error. Any help would be greatly appreciated.

The following is my config file:

input {  
file {  
path =\> "/omt/opp/logstash-5.6.1/processingP123.log"  
type =\> "OldLog"  
start\_position =\> "beginning"  
}  
}

filter{  
if [type] == "OldLog" {  
grok {  
match =\> ["message", "(?%{MONTHNUM}.%{MONTHDAY}.%{YEAR} %{TIME})%{SPACE}(?\<P.23.P24.ABK\>%{DATA:StatusEvent}:%{SPACE}BkgLeg:?%{SPACE}%{BASE16NUM:BkgLegs})?%{GREEDYDATA:message}"]  
}  
}  
}

output {  
if [type] == "OldLog" {  
elasticsearch {  
index =\> "testing"  
hosts =\> "[http://mon.bev.tuesdcorp.com/elasticsearch](http://mon.bev.tuesdcorp.com/elasticsearch)"  
}  
}  
}

the config file works when I try to run it locally on my windows computer and the output is localhost:9200 but not when I try to do it on our linux environment. So the grok filter is working. The pipeline also succeeds in starting but no information is sent.

The error I receive is:

:WARN No appenders could be found for logger (org.apache.http.client.protocol.RequestAuthCache).  
log4j:WARN Please initialize the log4j system properly.
