I am new to logstash on ubuntu. I am using file plugin in the input where I have given the path for displaying the content of the file on the stdout.This is my configuration file
input{
file{
path =>"/home/om/Desktop/app/logstash/logstash-1.4.22/logs.txt"
start_position => "beginning"
}
}
output{
stdout{}
}
I am not getting any output on the console. I want to dump the data from the .txt file on the console.
Use this configuration:
input {
file {
path => [ "\\IpAddress\logs/filename.*.*_bak"" ]
start_position => "beginning"
}
}
output {
elasticsearch {
bind_host => "127.0.0.1"
port => "9200"
protocol => http
}
stdout { codec => rubydebug }
}
And also checking with below commands:
>logstash --configtest -f logstash.conf --> for configuration testing
>logstash --debug -f logstash.conf --> for debugging

I tried starting the logstash with the below command
logstash-7.10.2\logstash -f logstash.conf
logstash.conf
input{
file{
path => "D://server.log" start_position=> "beginning" type => "logs"
}
}
filter {
grok {
match => {"message" => "%{TIMESTAMP_ISO8601:logtime} \[%{NOTSPACE:thread}\] \[%{LOGLEVEL:loglevel}\] %{GREEDYDATA:line}"
}
}
}
output {
if "ERROR" in [loglevel]
{
elasticsearch {
hosts => ["localhost:9200"]
index => "logstash"
}
}
}
command prompt displayed the below text and did not start logstash.

Have you tried staring logstash in debug mode .
--log.level DEBUG
Pipeline looks okay. Can you try adding below output to see if you the pattern and log data matches. Just to rule out any grokparsefailures.
output {
stdout { codec => rubydebug }
if "ERROR" in [loglevel]
{
elasticsearch {
hosts => ["localhost:9200"]
index => "logstash"
}
}
}
I am trying to set up a very simple logstash config
input {
file {
path => "/path/to/my/log/file"
start_position => "beginning"
ignore_older => 0
}
}
filter {
}
output {
stdout {
codec => rubydebug
}
}
and here is how i start logstash
[logstash-7.1.1]$ bin/logstash -r -f log.conf
but here is all i see on the console
Sending Logstash logs to path/to/logstash-7.1.1/logs which is now configured via log4j2.properties

i can see that
No sincedb_path set, generating one based on the "path" setting {:sincedb_path=>"path/to/logstash-7.1.1/data/plugins/inputs/file/.sincedb_8164b23a475b43f1b0c9aba125f7f5cf", :path=>["/path/to/my/log/file"]}
so the path seems correct. Also, my log file is not empty.
What am i doing wrong? Why cant I see the content of my log file on the console?
input {
file {
path => "/salaries.csv"
start_position => "beginning"
type => "data"
}
}
filter {
csv{
separator => ","
}
}
output {
stdout {
codec => rubydebug
}
}

I am trying to configure my Logstash to read from a specified log file. When I configure it to read from stdin it works as expected, my input results in a message from Logstash and displays in my Kibana UI.
$ cat /tmp/logstash-stdin.conf
input {
stdin {}
}
output {
elasticsearch { hosts => ["localhost:9200"] }
stdout { codec => rubydebug }
}
$./logstash -f /tmp/logstash-stdin.conf
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path //usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console
The stdin plugin is now waiting for input:
hellloooo
{
"#version" => "1",
"host" => "myhost.com",
"#timestamp" => 2017-11-17T16:05:41.595Z,
"message" => "hellloooo"
}
However, when I run Logstash with a file input I get no indication that the file is loaded into Logstash, and it does not show in Kibana.
$ cat /tmp/logstash-simple.conf
input {
file {
path => "/tmp/test_log.txt"
type => "syslog"
}
}
output {
elasticsearch { hosts => ["localhost:9200"] }
stdout { codec => rubydebug }
}
$ ./logstash -f /tmp/logstash-simple.conf
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults

Any suggestions of how I can troubleshoot why my Logstash is not ingesting the configured file?
By default the file input plugin starts reading at the end of the file, so only lines added after Logstash starts will be processed. To read all existing lines upon startup add the option "start_position" => "beginning" to the configuration, as explained in documentation.
I have created a simple json like below
[
{
"Name": "vishnu",
"ID": 1
},
{
"Name": "vishnu",
"ID": 1
}
]
I am holding this values in file named simple.txt . Then i used file beat to listen the file and send the new updates to port 5043,on other side i started the log-stash service which listen to this port in order to parse and pass the json to elastic search.
log-stash is not processing the json values,it hangs in the middle.
logstash
input {
beats {
port => 5043
host => "0.0.0.0"
client_inactivity_timeout => 3600
}
}
filter {
json {
source => "message"
}
}
output {
stdout { codec => rubydebug }
}
filebeat config:
filebeat.prospectors:
- input_type: log
paths:
- filepath
output.logstash:
hosts: ["localhost:5043"]
Logstash output

Every time when i am running log-stash using command
logstash -f logstash.conf
And since there is no processing of json i am stopping that service by pressing ctrl + c .
Please help me in finding the solution.Thanks in advance.
finally i got ended up with config like this.It works for me.
input
{
file
{
codec => multiline
{
pattern => '^\{'
negate => true
what => previous
}
path => "D:\elasticdb\logstash-tutorial.log\Test.txt"
start_position => "beginning"
sincedb_path => "D:\elasticdb\logstash-tutorial.log\null"
exclude => "*.gz"
}
}
filter {
json {
source => "message"
remove_field => ["path","#timestamp","#version","host","message"]
}
}
output {
elasticsearch { hosts => ["localhost"]
index => "logs"
"document_type" => "json_from_logstash_attempt3"
}
stdout{}
}
Json format:
{"name":"sachin","ID":"1","TS":1351146569}
{"name":"sachin","ID":"1","TS":1351146569}
{"name":"sachin","ID":"1","TS":1351146569}
Logstash 5.2.1
I can't read JSON documents from a local file using Logstash. There are no documents in the stdout.
I run Logstash like this:
./logstash-5.2.1/bin/logstash -f logstash-5.2.1/config/shakespeare.conf --config.reload.automatic
Logstash config:
input {
file {
path => "/home/trex/Development/Shipping_Data_To_ES/shakespeare.json"
codec => json {}
start_position => "beginning"
}
}
output {
stdout {
codec => rubydebug
}
}
Also, I tried with charset:
...
codec => json {
charset => "UTF-8"
}
...
Also, I tried with/without json codec in the input and with filter:
...
filter {
json {
source => "message"
}
}
...

Why Logstash doesn't put my JSON documents in stdout?
Did you try including the file type within your file input:
input {
file {
path => "/home/trex/Development/Shipping_Data_To_ES/shakespeare.json"
type => "json" <-- add this
//codec => json {} <-- for the moment i'll comment this
start_position => "beginning"
}
}
And then have your filter as such:
filter{
json{
source => "message"
}
}
OR if you're going with the codec plugin make sure to have the synopsis as such within your input:
codec => "json"
OR you might want to try out json_lines plugin as well. Hope this thread comes in handy.
It appears that sincedb_path is important to read JSON files. I was able to import the JSON only after adding this option. It is needed to maintain the current position in the file to be able to resume from that position in case the import is interrupted. I don't need any position tracking, so I just set this to /dev/null and it works.
The basic working Logstash configuration:
input {
file {
path => ["/home/trex/Development/Shipping_Data_To_ES/shakespeare.json"]
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
output {
stdout {
codec => json_lines
}
elasticsearch {
hosts => ["localhost:9200"]
index => "shakespeare"
}
}
