Logstash could not be started because there is already another instance using the configured data directory - Windows7

Hi,

How do i kill multiple instances, i do not wish to run multiple instances of logstash, but however, it is getting created in the background!

How do i kill it in windows 7.

However, on changing the path.data in YML file, i get this below error:

[2018-06-26T09:23:55,708][ERROR][org.logstash.Logstash ] java.lang.IllegalStateException: Logstash stopped processing because of an error: (SystemExit) exit

Config file :

input {
file {
path => "D:\Temp\KT\TraceLog-2018-06-12T15-28-22.528.log"
}
}

output {
stdout {
codec => rubydebug
}
}

logstash YML

path.data:"C: \ELK\logstash-6.3.0\data1"

Logstash doesn't start by itself on Windows so this is something you need to dig into on your side.

path.data:"C: \ELK\logstash-6.3.0\data1"

Not sure if it matters but there should be a space after "path.data:". If that doesn't help, post the non-comment lines of your logstash.yml formatted as preformatted text using markdown notation or the </> toolbar button.

i solved it by copying the folder to a different location and installing again ! plus running it using the below command ,

D:\logstash-6.3.0\bin>logstash -f logS.config < "D:\Temp\KT\TraceLog-2018-06-12T
15-47-31.830.log

Config file :

**input {
stdin{

}

}

filter {
grok {
match => {"message" => "<%{WORD:loglevel}>%{TIMESTAMP_ISO8601:timestamp}%{GREEDYDATA:logmessage}'%{PATH:path}'%{WORD:category}%{WORD:user}%{NUMBER:threadid}%{BASE16NUM:errorcode}%{WORD:application}%{WORD:machine}"}
}
}
output {
file {
path => "D:\logstash-6.3.0\data1\output8.csv"
}
}

I don't know for some reason, it isnt working if i pass path in the input {} , the command line keeps executing and nothing happens.

input {
file{
path => "D:\Temp\KT\TraceLog-2018-06-12T15-28-22.528.log"
}

}

the above input {} doesnt work.

What if you append a line to the file with

echo whatever >> D:\logstash-6.3.0\data1\output8.csv

?

@magnusbaeck

echo whatever >> D:\logstash-6.3.0\data1\output8.csv

I have no problem in getting the output but the input {} component is where im facing issue ! it doesnt work if i add path to the input{}

[magnusbaeck (Magnus Bäck)]

Sorry, that was the wrong path. This is what I meant:

echo whatever >> D:\Temp\KT\TraceLog-2018-06-12T15-28-22.528.log

[thoppaen (rakesh)]

The compiler gets stuck there for good ! it doesnt respond.

That's expected with your configuration, but does the "whatever" line end up in output8.csv?
