Currently, I have a program that writes a json array into a json file. The json file is initially blank. I also have an instance of logstash running with the following config file.
input{
file{
path => "/Users/CP4/Downloads/gs-accessing-data-mysql-master/complete/example.json"
codec => "json"
start_position => "beginning"
ignore_older => 0
}
}
filter {
mutate {
gsub => [ "message","\[",""]
gsub => [ "message","\n",""]
gsub => [ "event","\},\{",","]
}
json { source => message }
}
output{
elasticsearch{
hosts => "localhost:9200"
index => "test123"
}
stdout { codec => rubydebug }
}
For some reason, logstash will only read the file once I go in and make some changes manually, rather than when my program writes json to it. What could be causing this? Is the way my config file is set up wrong? Thanks.

Logstash is all about reading logs from specific location and based on you interested information you can create index in elastic search or other output also possible.
Example of logstash conf
input {
file {
# PLEASE SET APPROPRIATE PATH WHERE LOG FILE AVAILABLE
#type => "java"
type => "json-log"
path => "d:/vox/logs/logs/vox.json"
start_position => "beginning"
codec => json
}
}
filter {
if [type] == "json-log" {
grok {
match => { "message" => "UserName:%{JAVALOGMESSAGE:UserName} -DL_JobID:%{JAVALOGMESSAGE:DL_JobID} -DL_EntityID:%{JAVALOGMESSAGE:DL_EntityID} -BatchesPerJob:%{JAVALOGMESSAGE:BatchesPerJob} -RecordsInInputFile:%{JAVALOGMESSAGE:RecordsInInputFile} -TimeTakenToProcess:%{JAVALOGMESSAGE:TimeTakenToProcess} -DocsUpdatedInSOLR:%{JAVALOGMESSAGE:DocsUpdatedInSOLR} -Failed:%{JAVALOGMESSAGE:Failed} -RecordsSavedInDSE:%{JAVALOGMESSAGE:RecordsSavedInDSE} -FileLoadStartTime:%{JAVALOGMESSAGE:FileLoadStartTime} -FileLoadEndTime:%{JAVALOGMESSAGE:FileLoadEndTime}" }
add_field => ["STATS_TYPE", "FILE_LOADED"]
}
}
}
filter {
mutate {
# here converting data type
convert => { "FileLoadStartTime" => "integer" }
convert => { "RecordsInInputFile" => "integer" }
}
}
output {
elasticsearch {
# PLEASE CONFIGURE ES IP AND PORT WHERE LOG DOCs HAS TO PUSH
document_type => "json-log"
hosts => ["localhost:9200"]
# action => "index"
# host => "localhost"
index => "locallogstashdx_new"
# workers => 1
}
stdout { codec => rubydebug }
#stdout { debug => true }
}

I've config like this
input {
file {
path => "/opt/data/user-*.json"
type => "json"
start_position => "beginning"
sincedb_path => "/dev/null"
tags => ["user"]
}
}
filter {
json {
source => "message"
}
}
output {
stdout { codec => rubydebug }
}
When I run logstash with --debug, it shows the message without any output, seems it keep waiting for new content to be consumed (but I've set sincedb_path => "/dev/null" already)
_globbed_files: /opt/data/user-*.json: glob is: ["/opt/data/user-2016-08-08.json"] {:level=>:debug, :file=>"filewatch/watch.rb", :line=>"346", :method=>"_globbed_files"}
Pushing flush onto pipeline {:level=>:debug, :file=>"logstash/pipeline.rb", :line=>"458", :method=>"flush"}
Pushing flush onto pipeline {:level=>:debug, :file=>"logstash/pipeline.rb", :line=>"458", :method=>"flush"}
When I change the input to stdin and paste the json in my data file, then it is ok.
input {
stdin{}
}
I had been using the multline codec of logstash for my java exceptions. However, recently I wanted to capture more things and hence used another pattern. This causes my logstash not to read file even though I am using sincedb_path attribute.
My configurations file -
input {
file {
type => "pa"
path => "/home/jigar/POC/Docs/smalllogs/test"
codec => multiline {
pattern => "^%{DATESTAMP}"
negate => true
what => "previous"
}
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
grok {
match => [ "message", "%{DATESTAMP:actualTimeStamp}%{SPACE}%{LOGLEVEL:level}%{SPACE}%{GREEDYDATA:identifier}%{SYSLOG5424SD:Id}%{SPACE}%{JAVACLASS:package}:%{INT:lineNum}%{SPACE}-%{SPACE}%{DATA:mydata}\n(\t)?%{GREEDYDATA:stack}" ]
}
}
output {
elasticsearch {
cluster => "smartdebugger"
protocol => "http"
host => "localhost"
}
stdout { codec =>rubydebug }
}
Can somebody please help me why logstash is not able to read the file.
I am using logstash for the first time and trying to setup a simple pipeline for just printing the nginx logs. Below is my config file
input {
file {
path => "/var/log/nginx/*access*"
}
}
output {
stdout { codec => rubydebug }
}
I have saved the file as /opt/logstash/nginx_simple.conf
And trying to execute the following command
sudo /opt/logstash/bin/logstash -f /opt/logstash/nginx_simple.conf
However the only output I can see is:
Logstash startup completed
Logstash shutdown completed
The file is not empty for sure. As per my understanding I should be seeing the output on my console. What am I doing wrong ?
Make sure that the character encoding of your logfile is UTF-8. If it is not, try to change it and restart the Logstash.
Please try this code as your Logstash configuration, in order to setup a simple pipeline for just printing the nginx logs.
input {
file {
path => "/var/log/nginx/*.log"
type => "nginx"
start_position => "beginning"
sincedb_path=> "/dev/null"
}
}
filter {
if [type] == "nginx" {
grok {
patterns_dir => "/home/krishna/Downloads/logstash-2.1.0/pattern"
match => {
"message" => "%{NGINX_LOGPATTERN:data}"
}
}
}
date {
match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
}
stdout { codec => rubydebug }
}

I am not able to load all files into elastic search , I didn't understand the problem here. can any body help to to how to parse multiple files into logstash config files ???
