How to see the requests sent by LogStash to the elasticsearch output in Fiddler? - logstash

Question

I have LS_JAVA_OPTS = -DproxySet=true -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8888
And yet, I see no traffic to my elasticsearch node from logstash in Fiddler.
I know my elasticsearch is up and running. When I curl it, Fiddler clearly shows the requests, so it is something about jruby that does not route requests through Fiddler.
I am not calling jruby directly. Rather I use the bin\logstash.bat script.
Appendix
My conf file:
input {
file {
path => 'c:/log/bje-Error.log'
sincedb_path => "NUL"
codec => plain {
charset => "ISO-8859-1"
}
codec => multiline {
pattern => "^%{TIMESTAMP_ISO8601} "
negate => true
what => previous
}
start_position => beginning
ignore_older => 0
}
}
filter {
grok {
match => { "message" => "%{TIMESTAMP_ISO8601:timestamp} \[%{BASE10NUM:thread:int}] %{WORD:machine}:%{WORD:service} \[%{BASE10NUM:localId:int}?:%{UUID:logId}?:(?<jobKind>[^:]+)?:%{BASE10NUM:jobDefinitionId:int}? %{WORD:namespace}?:%{WORD:job}?:(?<customCtx>[^\]]*)\] %{LOGLEVEL:level} %{NOTSPACE:logger} - (?<text>(?m:.*))" }
}
}
output {
stdout { codec => rubydebug }
elasticsearch {
document_type => 'logs_bje'
hosts => ["ncesearch01"]
}
}
Testing in powershell:
PS E:\logstash-2.3.2\bin> (ConvertFrom-Json((Invoke-WebRequest "http://ncesearch01:9200/logstash-*/_count").Content)).count
24666
PS E:\logstash-2.3.2\bin> .\logstash.bat -f C:\dayforce\DayforceDEV\elk\logstach.conf
LS_JAVA_OPTS was set to [-DproxySet=true -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8888]. This will be appended to the JAVA_OPTS [ -XX:HeapDumpPath="$LS_HOME/heapdump.hprof"]

PS E:\logstash-2.3.2\bin>
As you can see, http://ncesearch01:9200/logstash-*/_count returns incremented count, hence running logstash did send a request to the elasticsearch. However, it bypassed Fiddler, despite the LS_JAVA_OPTS.

Answer 1

I find some possible reasons for this condition，although I did not try.May this answer should be called "discussion"，I`m sorry.
1.You may need a linux OS instead of windows，for the reason，
I am not sure this question has been deal in the latest logstash version
you may be interested in this,Make JAVA_OPTS and LS_JAVA_OPTS work consistently on Windows
2.As we see，the most possible is that
logstash ES_output plugin use the http way to send message
after logstash-2.0,you may use the old version?

If anyone has any ideas,your share will be expected~
