Data missed a lot in logstash version 5.0,
is it a serous bug ,when a config the config file so many times ,it useless,data lost happen again and agin, how to use logstash to collect log event property ?
any reply will thankness
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'm trying to collect logs using Logstash where I have different kinds of logs in the same file.
I want to extract certain fields if they exist in the log, and otherwise do something else.
input{
file {
path => ["/home/ubuntu/XXX/XXX/results/**/log_file.txt"]
start_position => "beginning"
}
}
filter {
grok{
match => { "message" => ["%{WORD:logger} %{SPACE}\-%{SPACE} %{LOGLEVEL:level} %{SPACE}\-%{SPACE} %{DATA:message} %{NUMBER:score:float}",
"%{WORD:logger} %{SPACE}\-%{SPACE} %{LOGLEVEL:level} %{SPACE}\-%{SPACE} %{DATA:message}"]}
}
}
output{
elasticsearch {
hosts => ["X.X.X.X:9200"]
}
stdout { codec => rubydebug }
}
for example, log type 1 is:
root - INFO - Best score yet: 35.732
and type 2 is:
root - INFO - Starting an experiment
One of the problems I face is that when a message doesn't contain a number, the field still exists as null in the JSON created which prevents me from using desired functionalities in Kibana.
One option, is just to add a tag on logstash when field is not defined to be able to have a way to filter easily on kibana side. The null value is only set during the insertion in elasticsearch (on logstash side, the field is not defined)
This solution looks like this in you case :
filter {
grok{
match => { "message" => ["%{WORD:logger} %{SPACE}\-%{SPACE} %{LOGLEVEL:level} %{SPACE}\-%{SPACE} %{DATA:message} %{NUMBER:score:float}",
"%{WORD:logger} %{SPACE}\-%{SPACE} %{LOGLEVEL:level} %{SPACE}\-%{SPACE} %{DATA:message}"]}
}
if ![score] {
mutate { add_tag => [ "score_not_set" ] }
}
}
Here is an exmple of event message:
{
"timestamp":"2016-03-29T22:35:44.770750-0400",
"flow_id":45385792,

"dest_ip":"2.2.2.2",
"dest_port":52934,
"proto":"TCP",
"alert":{
"action":"allowed",
"gid":1,
"signature_id":4027,
"rev":0,
"signature":"FTP Successful Login",
"category":"",

}
input
beats
port => 5044
codec => json
type => "SuricataIDPS"
My Logstash config file is the following:
output
elasticsearch
hosts => ["localhost:9200"]
sniffing => true
manage_template => false
index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
#document_type => "%{[#metadata][type]}"
I'd like to be able to rename the field alert.signature,
How can I do so?... Seems that it does not recognize that field...
Thanks for your help!

You have to define mutate filter within filter stanza:
filter {
mutate {
rename => [ "[alert][signature]", "[alert][signature_renamed]" ]
}
}
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 trying to get logstash to parse key-value pairs in an HTTP get request from my ELB log files.
the request field looks like
http://aaa.bbb/get?a=1&b=2
I'd like there to be a field for a and b in the log line above, and I am having trouble figuring it out.
My logstash conf (formatted for clarity) is below which does not load any additional key fields. I assume that I need to split off the address portion of the URI, but have not figured that out.
input {
file {
path => "/home/ubuntu/logs/**/*.log"
type => "elb"
start_position => "beginning"
sincedb_path => "log_sincedb"
}
}
filter {
if [type] == "elb" {
grok {
match => [ "message", "%{TIMESTAMP_ISO8601:timestamp}
%{NOTSPACE:loadbalancer} %{IP:client_ip}:%{NUMBER:client_port:int}
%{IP:backend_ip}:%{NUMBER:backend_port:int}
%{NUMBER:request_processing_time:float}
%{NUMBER:backend_processing_time:float}
%{NUMBER:response_processing_time:float}
%{NUMBER:elb_status_code:int}
%{NUMBER:backend_status_code:int}
%{NUMBER:received_bytes:int} %{NUMBER:sent_bytes:int}
%{QS:request}" ]
}
date {
match => [ "timestamp", "ISO8601" ]
}
kv {
field_split => "&?"
source => "request"
exclude_keys => ["callback"]
}
}
}
output {
elasticsearch { host => localhost }
}
kv will take a URL and split out the params. This config works:
input {
stdin { }
}
filter {
mutate {
add_field => { "request" => "http://aaa.bbb/get?a=1&b=2" }
}
kv {
field_split => "&?"
source => "request"
}
}
output {
stdout {
codec => rubydebug
}
}
stdout shows:
{
"request" => "http://aaa.bbb/get?a=1&b=2",
"a" => "1",
"b" => "2"
}
That said, I would encourage you to create your own versions of the default URI patterns so that they set fields. You can then pass the querystring field off to kv. It's cleaner that way.
UPDATE:
For "make your own patterns", I meant to take the existing ones and modify them as needed. In logstash 1.4, installing them was as easy as putting them in a new file the 'patterns' directory; I don't know about patterns for >1.4 yet.
MY_URIPATHPARAM %{URIPATH}(?:%{URIPARAM:myuriparams})?
MY_URI %{URIPROTO}://(?:%{USER}(?::[^#]*)?#)?(?:%{URIHOST})?(?:%{MY_URIPATHPARAM})?
Then you could use MY_URI in your grok{} pattern and it would create a field called myuriparams that you could feed to kv{}.
