I have logs where each event is:
ExitNode FF33F91CC06B6CC5C3EE804E7D8DBE42CB5707F9
Published 2017-11-05 02:55:09
LastStatus 2017-11-05 04:02:27
ExitAddress 66.42.224.235 2017-11-05 04:06:26
I tried to use multiline:
input {
file {
path => "/path/input"
}
}
filter {
multiline {
pattern => "^\b[A-Za-z]{8}\b"
what => "next"
}
}
filter {
multiline {
pattern => "^\b[A-Za-z]{8}\b"
what => "next"
}
}
filter {
multiline {
pattern => "^\b[A-Za-z]{11}\b"
what => "previous"
}
}
output {
file {
codec => rubydebug
path => "/path/output"
}
}
And I get something like this:
{
"path" => "/path/input",
"#timestamp" => 2017-11-05T10:25:34.112Z,
"#version" => "1",
"host" => "HOST",
"message" => "ExitNode FE3CB742E73674F1BC2382723209ECEE44AD4AEC\nPublished 2017-11-04 20:34:55\nLastStatus 2017-11-04 21:03:26\nExitAddress 77.250.227.12 2017-11-04 21:06:45",
"tags" => [
[0] "multiline"
]
}
And I can't grok this message field because I don't know how to remove or replace \n and gsub => ["message", "\n", "Line_Break"] doesn't work properly.
Thanks
From the comment of #baudsp:
mutate {
gsub =>
["message", "[\r\n]","_"]
}

I have a string field called description delimited with _.
I split it as follows:
filter {
mutate {
split => ["description", "_"]
add_field => {"location" => "%{[description][3]}"}
}
How can I check if the split values are empty or not?
I have attempted:
if !["%{[description][3]}"] {
# do something
}
if ![[description][3]] {
# do something
}
if ![description][3] {
# do something
}
None of them work.
The goal is to have the value of the new field location as its actual value or a generic value such as NA.
you made a really simple mistake with your mutate split.
this
mutate {
split => ["description", "_"]
add_field => {"location" => "%{[description][3]}"}
}
should have been
mutate {
split => ["description"=> "_"] <=== see I removed the comma and added =>
add_field => {"location" => "%{[description][3]}"}
}
here is sample I tested out with
filter {
mutate {
remove_field => ["headers", "#version"]
add_field => { "description" => "Python_Java_ruby_perl " }
}
mutate {
split => {"description" => "_"}
}
if [description][4] {
mutate {
add_field => {"result" => "The 4 th field exists"}
}
} else {
mutate {
add_field => {"result" => "The 4 th field DOES NOT exists"}
}
}
and the result on console (since there is no 4 th element, it went to else block
{
"host" => "0:0:0:0:0:0:0:1",
"result" => "The 4 th field DOES NOT exists", <==== from else block
"#timestamp" => 2020-01-14T19:35:41.013Z,
"message" => "hello",
"description" => [
[0] "Python",
[1] "Java",
[2] "ruby",
[3] "perl "
]
}
I'm trying to add LEVEL field (so it shows up in Kibana). My logstash.conf

Output I'm getting. Still missing received_at and level:
In that part of the configuration:
add_field => {
"received_at" => "%{#timestamp}"
"received_from" => "%{host}"
"level" => "levell"
}
When using "level" => "levell", you just put the String levell in the field level. To put the value of the field named levell, you have to use %{levell}. So in you case, it would look like:
add_field => {
"received_at" => "%{#timestamp}"
"received_from" => "%{host}"
"level" => "%{levell}"
}
Also the grok#match, according to the documentation:
A hash that defines the mapping of where to look, and with which patterns.
So trying to match on the levell field won't work, since it look like it doesn't exist yet. And the grok pattern you're using to match the message field don't match the example you provided.
I have a log line like this:
09 Nov 2018 15:51:35 DEBUG api.MapAnythingProvider - Calling API For Client: XXX Number of ELEMENTS Requested YYY
I want to ignore all other log lines and only want those lines that have the words "Calling API For Client" in it. Further, I am only interested in the String XXX and Number YYY.
Thanks for the help.

I have an issue with converting value through logstash, I can't find solution for it. it seems to be linked to the date.

What version of Logstash are you using?
On Logstash 5.2.2 with the following Logstash config:
input {
stdin{}
}
filter {
grok {
match => {"message" => '\[%{TIMESTAMP_ISO8601:timestamp}\] %{WORD:module}.%{WORD:level}: (?<log_message>.*) \[\] \[\]' }
}
json {
source => "log_message"
target => "flightSearchRequest"
remove_field=>["log_message"]
}
date {
match => [ "timestamp", "YYYY-MM-dd HH:mm:ss" ]
timezone => "Asia/Jerusalem"
}
}
output{
stdout {codec => "rubydebug"}
}
I get a perfectly correct result and no errors, when I pass your log line as input:
{
"#timestamp" => 2017-08-15T09:30:17.000Z,
"flightSearchRequest" => {
"action" => "processed",
"sessionId" => "a216925---ff5992be7520924ff25992be75209c7",
"time" => 1502789417,
"page" => "order",
"type" => "bookingProcess"
},
"level" => "INFO",
"module" => "api",
"#version" => "1",
"message" => "[2017-08-15 12:30:17] api.INFO: {\"sessionId\":\"a216925---ff5992be7520924ff25992be75209c7\",\"action\":\"processed\",\"time\":1502789417,\"type\":\"bookingProcess\",\"page\":\"order\"} [] []",
"timestamp" => "2017-08-15 12:30:17"
}
I've removed the check for "type" in the beginning, can you test if that can affect the result?
I'am getting crazy with my logstash configuration.
I can't find a way to replace the #timestamp field with another:
Here is what logstash receive:

I tried :
match => [ "time_req_rcv4c_or_snt4b","dd/MMM/yyyy:HH:mm:ss Z" ]
remove_field => "time_req_rcv4c_or_snt4b"
and
match => [ "[time_req_rcv4c_or_snt4b]","dd/MMM/yyyy:HH:mm:ss Z" ]
remove_field => "[time_req_rcv4c_or_snt4]
Anybody can explain me what i missed. I didn't find anything relevant on google for the moment.
From your output:
"time_req_rcv4c_or_snt4b" => "[14/Feb/2017:14:38:44 +0100]",
Your date field has [] around it, so you need to match those in your date pattern or strip them off when you first match the date.
