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!

I have configured my logstash file like this
input {
kafka {
topics => [
...
]
bootstrap_servers => "${KAFKA_URL}"
codec => "json"
}
}
filter {
...
}
output {
elasticsearch {
index => "logstash-%{organizationId}"
hosts => ["${ELASTICSEARCH_URL}"]
codec => "json"
}
stdout { codec => json }
}
the elasticsearch output url is coming from the environment variable.
I want to improve the behavior of logstash and change dynamically the output server url based on the some info that came in the kafka message
It is possible to do it?
thanks in advance
Im having a problem with ELK Stack + Filebeat.
Filebeat is sending apache-like logs to Logstash, which should be parsing the lines. Elasticsearch should be storing the split data in fields so i can visualize them using Kibana.
Problem:
Elasticsearch recieves the logs but stores them in a single "message" field.
Desired solution:
Input:
10.0.0.1 some.hostname.at - [27/Jun/2017:23:59:59 +0200]
ES:
"ip":"10.0.0.1"
"hostname":"some.hostname.at"
"timestamp":"27/Jun/2017:23:59:59 +0200"
My logstash configuration:
input {
beats {
port => 5044
}
}
filter {
if [type] == "web-apache" {
grok {
patterns_dir => ["./patterns"]
match => { "message" => "IP: %{IPV4:client_ip}, Hostname: %{HOSTNAME:hostname}, - \[timestamp: %{HTTPDATE:timestamp}\]" }
break_on_match => false
remove_field => [ "message" ]
}
date {
locale => "en"
timezone => "Europe/Vienna"
match => [ "timestamp", "dd/MMM/yyyy:HH:mm:ss Z" ]
}
useragent {
source => "agent"
prefix => "browser_"
}
}
}
output {
stdout {
codec => rubydebug
}
elasticsearch {
hosts => ["localhost:9200"]
index => "test1"
document_type => "accessAPI"
}
}
My Elasticsearch discover output:
I hope there are any ELK experts around that can help me.
Thank you in advance,
Matthias
The grok filter you stated will not work here.
Try using:
%{IPV4:client_ip} %{HOSTNAME:hostname} - \[%{HTTPDATE:timestamp}\]
There is no need to specify desired names seperately in front of the field names (you're not trying to format the message here, but to extract seperate fields), just stating the field name in brackets after the ':' will lead to the result you want.
Also, use the overwrite-function instead of remove_field for message.
More information here:
https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html#plugins-filters-grok-options
It will look similar to that in the end:
filter {
grok {
match => { "message" => "%{IPV4:client_ip} %{HOSTNAME:hostname} - \[%{HTTPDATE:timestamp}\]" }
overwrite => [ "message" ]
}
}
You can test grok filters here:
http://grokconstructor.appspot.com/do/match
I copied
{"name":"myapp","hostname":"banana.local","pid":40161,"level":30,"msg":"hi","time":"2013-01-04T18:46:23.851Z","v":0}
from https://github.com/trentm/node-bunyan and save it as my logs.json. I am trying to import only two fields (name and msg) to ElasticSearch via LogStash. The problem is that I depend on a sort of filter that I am not able to accomplish. Well I have successfully imported such line as a single message but certainly it is not worth in my real case.
That said, how can I import only name and msg to ElasticSearch? I tested several alternatives using http://grokdebug.herokuapp.com/ to reach an useful filter with no success at all.
For instance, %{GREEDYDATA:message} will bring the entire line as an unique message but how to split it and ignore all other than name and msg fields?
At the end, I am planing to use here:
input {
file {
type => "my_type"
path => [ "/home/logs/logs.log" ]
codec => "json"
}
}
filter {
grok {
match => { "message" => "data=%{GREEDYDATA:request}"}
}
#### some extra lines here probably
}
output
{
elasticsearch {
codec => json
hosts => "http://127.0.0.1:9200"
index => "indextest"
}
stdout { codec => rubydebug }
}
I have just gone through the list of available Logstash filters. The prune filter should match your need.
Assume you have installed the prune filter, your config file should look like:
input {
file {
type => "my_type"
path => [ "/home/logs/logs.log" ]
codec => "json"
}
}
filter {
prune {
whitelist_names => [
"#timestamp",
"type",
"name",
"msg"
]
}
}
output {
elasticsearch {
codec => json
hosts => "http://127.0.0.1:9200"
index => "indextest"
}
stdout { codec => rubydebug }
}
Please be noted that you will want to keep type for Elasticsearch to index it into a correct type. #timestamp is required if you will view the data on Kibana.
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 trying to set long and lat for the Kibana Bettermap using Geoip. I'm using Logstash 1.4.2 and Elasticsearch 1.1.1 and the following is my configuration file:
input
{
stdin { }
}
filter
{
geoip
{
source => "ip"
}
}
output
{
elasticsearch { host => localhost }
stdout { codec => rubydebug }
}
When I send the following example ip address:
"ip":"00.00.00.00"
The result is as follows:
{
"message" => "\"ip\":\"00.000.00.00\"",
"#version" => "1",
"#timestamp" => "2014-10-20T22:23:12.334Z",
}
As you can see, no geoip coordinates, and nothing on my Kibana Bettermap. What can I do to get this Bettermap to work?
You aren't parsing the message... Either add codec => json to your stdin and send in {"ip":"8.8.8.8"} or use a grok filter to parse your input:
grok { match => ['message', '%{IP:ip}' ] }
