I'm new in ELK. In fact, I already installed Logstash, elasticsearch, and kibana on ubuntu 14.04. when I try to test ELK with an existing log file on my ubuntu, the logstash didn't load log into elasticsearch and showing nothing. This is my logstash config file : sudo gedit /etc/logstash/conf.d/logstash.conf
input {
file {
path => "/home/chayma/logs/catalina.2016-02-02.log"
start_position => "beginning"
}
}
filter {
grok {
match => { "message" => "%{COMMONAPACHELOG}" }
}
}
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
}
stdout
{
codec => rubydebug
}
}
However, my elasticsearch.yml contains:
cluster.name: my-application
node.name: node-1
node.master: true
node.data: true
index.number_of_shards: 1
index.number_of_replicas: 0
network.host: localhost
http.port: 9200
Please help
I presume Logstash and Elasticsearch are installed on same machine and Logstash is running?
sudo service logstash status
Try checking the Logstash log file to see if it's a connection issue or a syntax error (config looks OK, so probably the former):
tail -f /var/log/logstash/logstash.log
Does your COOMONAPACHELOG matches the log pattern that you are trying to parse using GROK ?
By default from the path on Ubuntu 14.04
/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-2.0.5/patterns/grok-patterns
You can verify the same here
https://grokdebug.herokuapp.com/
The GROK in our case is applying the following regex:
COMMONAPACHELOG %{IPORHOST:clientip} %{HTTPDUSER:ident} %{USER:auth} \[%{HTTPDATE:timestamp}\] "(?:%{WORD:verb} %{NOTSPACE:request}(?: HTTP/%{NUMBER:httpversion})?|%{DATA:rawrequest})" %{NUMBER:response} (?:%{NUMBER:bytes}|-)
Please provide with the log entries.
change your elasticsearch output by adding index name to it and try
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
index => "testindex-%{+YYYY.MM.dd}"
}
stdout
{
codec => rubydebug
}
}
You're missing input {}. input{} and output{} are necessary in logstash pipeline.
input {
file {
path => "/home/chayma/logs/catalina.2016-02-02.log"
start_position => "beginning"
}
}
}
Or you can check simple way whether text can forward to elasticsearch.
Just test with using stdin and stdout in terminal. Be sure local elasticsearch service is running.
input {
stdin {
type => "true"
}
}
filter {
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
}
stdout {
codec => rubydebug
}
}

I am new to logstash and filebeat. I am trying to set up multiple config files for my logstash instance.
Using filebeat to send data to logstash. Even if I have filters created for both the logstash config files, I am getting duplicate data.
Logstash config file - 1:
input {
beats {
port => 5045
}
}
filter {
if [fields][env] == "prod" {
grok { match => { "message" => "%{LOGLEVEL:loglevel}] %{GREEDYDATA:message}$" }
overwrite => [ "message" ]
}
}
}
output {
stdout {
codec => rubydebug
}
elasticsearch {
hosts => ["https://172.17.0.2:9200"]
index => "logstash-myapp-%{+YYYY.MM.dd}"
user => "elastic"
password => "password"
ssl => true
cacert => "/usr/share/logstash/certs/http_ca.crt"
}
}
logstash config file-2
input {
beats {
port => 5044
}
}
filter {
if [fields][env] == "dev" {
grok { match => { "message" => "%{LOGLEVEL:loglevel}] %{GREEDYDATA:message}$" }
overwrite => [ "message" ]
}
}
}
output {
stdout {
codec => rubydebug
}
elasticsearch {
hosts => ["https://172.17.0.2:9200"]
index => "logstash-myapp-%{+YYYY.MM.dd}"
user => "elastic"
password => "password"
ssl => true
cacert => "/usr/share/logstash/certs/http_ca.crt"
}
}
Logfile Content:
[INFO] First Line
[INFO] Second Line
[INFO] Third Line
Filebeat config:
filebeat.inputs:
- type: filestream
enabled: true
paths:
- /root/data/logs/*.log
fields:
app: test
env: dev
output.logstash:
# The Logstash hosts
hosts: ["172.17.0.4:5044"]
I know that even if we have multiple files for config, logstash processes each and every line of the data against all the filters present in all the config files. Hence we have put filters in each of the config files for "fields.env".
I am expecting 3 lines to be sent to Elasticsearch because "fields.env" is "dev", but it is sending 6 lines to Elasticsearch and duplicate data.
Pleas help.
The problem is that your two configuration files get merged, not only the filters but also the outputs.
So each log line making it into the pipeline through any of the input, will go through all filters (bearing any conditions of course) and all outputs (no conditions possible in output).
So the first log line [INFO] First Line coming in from port 5044, will only go through the filter guarded by [fields][env] == "dev", but then will go through each of the two outputs, hence why it ends up twice in your ES.
So the easy solution is to remove the output section from one of the configuration file, so that log lines only go through a single output.
The better solution is to create separate pipelines.
I have ELK 5.5.1 running in a Docker container, and it'll parse most of my logs, except for ones that originate from my Spring application. Kinda running out of ideas.
I've traced it down to the logstash->elasticsearch pipeline. Filebeat is doing its job, and Logstash is receiving logs from the application in question, based on tailing lostash's stdout log.
I wiped the docker volume that stores my ELK data clean, and started fresh with filebeat just forwarding the logs in question.
Take a log line like this:
FINEST|8384/0|Service tsoft_spring|17-08-31 14:12:01|2017-08-31 14:12:01.260 INFO 8384 --- [ taskExecutor-2] c.t.s.c.s.a.ConfirmationService : Will not persist empty response notes
Using a very minimal logstash configuration, it'll wind up being persisted in elasticsearch:
input {
beats {
port => 5044
ssl => false
}
}
filter {
if [message] =~ /tsoft_spring/ {
grok {
match => [ "message", "%{GREEDYDATA:logmessage}" ]
}
}
}
output {
stdout { }
elasticsearch { hosts => ["localhost:9200"] }
}
Using a more complete configuration, the log is just ignored by elastic, no grokparsefailure, no dateparsefailure:
input {
beats {
port => 5044
ssl => false
}
}
filter {
if [message] =~ /tsoft_spring/ {
grok {
match => [ "message", "%{WORD}\|%{NUMBER}/%{NUMBER}\|%{WORD}%{SPACE}%{WORD}\|%{TIMESTAMP_ISO8601:timestamp}\|%{TIMESTAMP_ISO8601}%{SPACE}%{LOGLEVEL:loglevel}%{SPACE}%{NUMBER:pid}%{SPACE}---%{SPACE}%{SYSLOG5424SD:threadname}%{SPACE}%{JAVACLASS:classname}%{SPACE}:%{SPACE}%{GREEDYDATA:logmessage}" ]
}
date {
match => [ "timestamp" , "yyyy-MM-dd HH:mm:ss" ]
}
}
}
output {
stdout { }
elasticsearch { hosts => ["localhost:9200"] }
}
I've checked that this pattern will parse that line, using http://grokconstructor.appspot.com/do/match#result, and I could've sworn it was working last weekend, but could be my imagination.
Maybe the problem here is not in your grok filter, but in the date match. Resulting year is 0017, instead of 2017. Maybe that's why you can't find the event in ES? Can you try this:
date {
match => [ "timestamp" , "yy-MM-dd HH:mm:ss" ]
}
I have Nginx logs being sent from Filebeat to Logstash which is indexing them into Elasticsearch.
Every entry gets indexed twice. Once with the correct grok filter and then again with no fields found except for the "message" field.
This is the logstash configuration.
02-beats-input.conf
input {
beats {
port => 5044
ssl => false
}
}
11-nginx-filter.conf
filter {
if [type] == "nginx-access" {
grok {
patterns_dir => ['/etc/logstash/patterns']
match => {"message" => "%{NGINXACCESS}"
}
date {
match => [ "timestamp", "dd/MMM/YYYY:HH:mm:ss Z", "d/MMM/YYYY:HH:mm:ss Z" ]
}
}
}

Check your filebeat configuration!
During setup I had accidentally un-commented and configured the output.elasticsearch section of the filebeat.yml.
I then also configured the output.logstash section of the configuration but forgot to comment out the elasticsearch output section.
This caused one entry to be sent to logstash where it was grok'd and another one to be sent directly to elasticsearch.
I have setup local ELK. All works fine, but before trying to write my own GROK pattern I wonder is there already one for Winston style logs?
That works great for Apache style log.
I would need something that works for Winston style. I think JSON filter would do the trick, but I am not sure.
This is my Winston JSON:
{"level":"warn","message":"my message","timestamp":"2017-03-31T11:00:27.347Z"}
This is my Logstash configuration file example:
input {
beats {
port => "5043"
}
}
filter {
json {
source => "message"
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
}
}
For some reason it is not getting parsed. No error.
Try like this instead:
input {
beats {
port => "5043"
codec => json
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
}
}
I'm sending data in a url to logstash 5.2 and I would like to parse it in logstash, so every url parameter becomes a variable in logstash and I can visualize it properly in kibana.
http://127.0.0.1:31311/?id=ID-XXXXXXXX&uid=1-37zbcuvs-izotbvbe&ev=pageload&ed=&v=1&dl=http://127.0.0.1/openpixel/&rl=&ts=1488314512294&de=windows-1252&sr=1600x900&vp=1600x303&cd=24&dt=&bn=Chrome%2056&md=false&ua=Mozilla/5.0%20(Macintosh;%20Intel%20Mac%20OS%20X%2010_11_3)%20AppleWebKit/537.36%20(KHTML,%20like%20Gecko)%20Chrome/56.0.2924.87%20Safari/537.36&utm_source=&utm_medium=&utm_term=&utm_content=&utm_campaign=
This is my logstash conf file:
input
{
http
{
host => "127.0.0.1"
port => 31311
}
}
output
{
elasticsearch
{
hosts => ["localhost:9200"]
}
stdout
{
codec => rubydebug
}
}
You could use the grok filter to match your params in your url as such:
filter {
grok {
match => [ "message", "%{URIPARAM:url}" ]
}
And then you might have to use kv filter in order to split your data:
kv {
source => "url"
field_split => "&"
}
This SO might become handy. Hope this helps!
