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 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 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'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'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}' ] }
I followed the steps in this document and I was able to do get some reports on the Shakespeare data.
I want to do the same thing with elastic search remotely installed.I tried configuring the "host" in config file but the queries still run on host as opposed to remote .This is my config file
input {
stdin{
type => "stdin-type" }
file {
type => "accessLog"
path => [ "/Users/akushe/Downloads/requests.log" ]
}
}
filter {
grok {
match => ["message","%{COMMONAPACHELOG} (?:%{INT:responseTime}|-)"]
}
kv {
source => "request"
field_split => "&?"
}
if [lng] {
kv {
add_field => [ "location" , ["%{lng}","%{lat}"]]
}
}else if [lon] {
kv {
add_field => [ "location" , ["%{lon}","%{lat}"]]
}
}
}
output {
elasticsearch {
host => "slc-places-qa-es3001.slc.where.com"
port => 9200
}
}
You need to add protocol => http in to make it use HTTP transport rather than joining the cluster using multicast.
