I am just a newbie to the ELK and trying some testing on this, i'm able to run some tests but while i'm trying a filter with grok & mutate to remoev & replace some feilds from my syslog output i'm getting into below error..
21:58:47.976 [LogStash::Runner] ERROR logstash.agent - Cannot create pipeline {:reason=>"Expected one of #, {, ,, ] at line 21, column 9 (byte 496) after filter {\n if [type] == \"syslog\" {\n grok {\n match => { \"message\" => \"%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:hostname} %{DATA:program}(?:\\[%{POSINT:pid}\\])?: %{GREEDYDATA:syslog_message}\" }\n }\n date {\n match => [ \"syslog_timestamp\", \"MMM d HH:mm:ss\", \"MMM dd HH:mm:ss\" ]\n }\n mutate {\n remove_field => [\n \"message\",\n \"pid\",\n \"port\"\n "}
Below is my config file ....

please suggest what i'm doing wrong and help to understand the remove & replace functions for the lagstash..
PS: my ELK version is 5.4
The Config you posted have lot of syntactical errors , the logsatsh has it's own config language and expects the config file to abide by the rule.
This link has complete logstash config language reference.
I made some corrections to your config file and posted here , Have added my comments and explanation of what was wrong in the config file itself

You can test whether the config file is syntactically correct by using logstash command line option -t this option will test and report the config file is syntactically correct
bin\logstash -f 'path-to-your-config-file' -t
Please let me know for any clarification
You have to add a comma after "port" in your logstash configuration file.
mutate {
remove_field => [
"message",
"pid",
"port",
"_grokparsefailure"
]

This is my logstash.conf:
input {
http {
host => "127.0.0.1"
port => 31311
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200"]
}
stdout {
codec => "rubydebug"
}
}
As a test, I ran this command in PowerShell:
C:\Users\Me\Downloads\curl-7.64.1-win64-mingw\bin> .\curl.exe -XPUT
'http://127.0.0.1:31311/twitter'
The following output was displayed inside my Logstash terminal:
{
"#timestamp" => 2019-04-09T08:32:09.250Z,
"message" => "",
"#version" => "1",
"headers" => {
"request_path" => "/twitter",
"http_version" => "HTTP/1.1",
"http_user_agent" => "curl/7.64.1",
"request_method" => "PUT",
"http_accept" => "*/*",
"content_length" => "0",
"http_host" => "127.0.0.1:31311"
},
"host" => "127.0.0.1"
}
When I then ran
C:\Users\Me\Downloads\curl-7.64.1-win64-mingw\bin> .\curl.exe -XGET
"http://127.0.0.1:9200/_cat/indices"
inside PowerShell, I saw
yellow open logstash-2019.04.09 1THStdPfQySWl1WPNeiwPQ 5 1 0 0 401b 401b
An index named logstash-2019.04.09 has been created in response to my PUT request, following the ElasticSearch convention.
My question is: If I want the index to have the same value as the {index_name} parameter I pass inside the the command .\curl.exe -XPUT 'http://127.0.0.1:31311/{index_name}', how should I configure the ElasticSearch output inside my logstash.conf file?
EDIT: Just to clarify, I want {index_name} to be read dynamically every single time I make a PUT request to create a new index. Is that even possible?
It is possible with the index output configuration option.
This configuration can be dynamic using the %{foo} syntax. Since you want the value of [headers][request_path] to be in the index configuration, you can do something like this:
output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "%{[headers][request_path]}"
}
}
For this to work the value [headers][request_path] field must not contain any of these characters: [ , \", *, \\, <, |, ,, >, /, ?].
I recommend that you use the gsub configuration option of the mutate filter. So, to remove all the forward slashes, you should have something like this:
filter{
mutate{
gsub => ["[headers][request_path]","/",""]
}
}
If the request path has several forward slashes, you could replace them with some character that will be accepted by elasticsearch.
So, your final logstash.conf file should look like this:
input {
http {
host => "127.0.0.1"
port => 31311
}
}
filter{
mutate{
gsub => ["[headers][request_path]","/",""]
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "%{[headers][request_path]}"
}
stdout {
codec => "rubydebug"
}
}
You can do so by adding an index configuration setting to your elasticsearch output section. e.g.
output {
elasticsearch {
hosts => ["http://localhost:9200"]
index => "yourindexnamehere"
}
stdout {
codec => "rubydebug"
}
}
I have Complete database in one index and daily bases i need to create or fetch 3 days records and store in CSV Format. Target is daily it take 3 days back records and store in CSV File. How To set start from Current date to Last 3 Days using only logstash.config?
My Logstash Config File
input {
elasticsearch {

gte start from current date and lt to last 3 days.
Working Logstash.config File Code
input {

I am trying to input a timestamp field in Logstash and i am getting dateparsefailure message.
My Message -
2014-08-01;11:00:22.123
Pipeline file
input {
stdin{}
#beats {
# port => "5043"
# }
}
# optional.
filter {
date {
locale => "en"
match => ["message", "YYYY-MM-dd;HH:mm:ss.SSS"]
target => "#timestamp"
add_field => { "debug" => "timestampMatched"}
}
}
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
}
stdout { codec => rubydebug }
}
Can someone tell me what i am missing ?
Update 1
I referred to the link - How to remove trailing newline from message field and now it works.
But, in my log message, i have multiple values other than timestamp
<B 2014-08-01;11:00:22.123 Field1=Value1 Field2=Value2
When i give this as input, it is not working. How to read a part of the log and make it as timestamp ?
Update 2
it works now.
Changed the config file as below
filter {
kv
{
}
mutate {
strip => "message"
}
date {
locale => "en"
match => ["timestamp1", "YYYY-MM-dd;HH:mm:ss.SSS"]
target => "#timestamp"
add_field => { "debug" => "timestampMatched"}
}
}
I am posting the answer below and steps i used to solve the issue so that i can help people like me.
Step 1 - I read the message in the form of key and value pair
Step 2 - I trimmed off the extra space that leads to parse exception
Step 3 - I read the timestamp value and other fields in respective fields.
input {
beats {
port => "5043"
}
}
# optional.
filter {
kv { }
date {
match => [ "timestamp", "yyyy-MM-dd HH:mm:ss,SSS" ]
remove_field => [ "timestamp" ]
}
}
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
}
}
ELK stack version
Logstash: 5.1.2
Kibana: 5.1.2
Elasticsearch:5.1.2
I have the below logstash configuration to send my router syslog events to elastic search.
My router is configured to send events to port 5514 and I can see the logs in Kibana.
BUT, I would like to to ensure all events send to port 5514 are given the type of syslog-network, which is then filtered by 11-network-filter.conf and send to Elasticsearch logstash-syslog-% index.
At present all the syslog events are falling under the logstash index.
Any ideas why?
03-network-input.conf
input {
syslog {
port => 5514
type => "syslog-network"
tags => "syslog-network"
}
}
11-network-filter.conf
filter {
if [type] == "syslog-network" {
grok {
match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp}%{GREEDYDATA:syslog_message}" }
add_field => [ "received_at", "%{#timestamp}" ]
add_field => [ "received_from", "%{host}" ]
}
syslog_pri { }
date {
match => [ "syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss" ]
}
}
}
30-elasticsearch-output.conf
output {
if "file-beats" in [tags] {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
document_type => "%{[#metadata][type]}"
}
}
else if "syslog-network" in [tags] {
elasticsearch {
hosts => ["localhost:9200"]
index => "logstash-syslog-%{+YYYY.MM.dd}"
}
}
else {
elasticsearch {
hosts => ["localhost:9200"]
index => "logstash-%{+YYYY.MM.dd}"
}
}
}
I want to convert logstash date type to this type 2015-12-03 03:01:00 and [message][3] - [message][1]
Date match doesn't work, how can I do?
Or %{[message][0]} expression is right or not.
filter {
multiline {
.............
}
grok {
match => { "message" => "%{GREEDYDATA:message}" }
overwrite => ["message"]
}
mutate {
gsub => ["message", "\n", " "]
split => ["message", " "]
}
date {
match => [ "%{[message][0]}","ISO8601"} ]
}
}
Message output like this:
"message" => [
[0] "2015-12-03T01:33:22+00:00"
[1]
[2]
[3] "2015-12-03T01:33:24+00:00"
]
Assuming your input is:
2015-12-03T01:33:22+00:00\n\n2015-12-03T01:33:24+00:00
You can grok that without split:
match => { message, "%{TIMESTAMP_ISO8601:string1}\\n\\n%{TIMESTAMP_ISO8601:string2}" }
You can then use the date{} filter with string1 or string2 as input.
