My logstash.conf is

codec => json_lines
}
}
filter {
grok {
patterns_dir => ["./patterns"]
match => {
'message' => '%{TIMESTAMP_ISO8601} %{LOGLEVEL:level} %{STRING} - \"log message \"Service Name=\"%{STRING} \"Content ID=\"%{STRING} \"Category=\"%{STRING} \"Timestamp=\"%{TIMESTAMP_ISO8601} \"Message=\"%{STRING} \"Unit Name=\"%{STRING}'

I know that STRING is not in grok-filters that's why I have defined a customer filter.
STRING ^[a-zA-Z0-9 !##$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]{1,}$
I am assuming that wherever I have used STRING that could include special characters ,spaces, numbers . Just like string in Java.
But still I am unable to filter my logs through this. Any help ?
You have anchored STRING to the start and end of line using ^ and $. It is never going to match in the way you are using it. Remove the ^ and $
Instead of custom patter STRING, you can simply use %{GREEDYDATA}. This will solve your problem.

I'm learning how to use the grok plugin. I have a message string like so
"type=CRYPTO_SESSION msg=audit(111111.111:111111): pid=22730 uid=0 auid=123 ses=123 subj=system_u:system_r:sshd_t:a1-a1:a1.a1234 msg='op=xx=xx cipher=xx ksize=111 mac=xx pfs=xxx spid=111 suid=000 rport=000 laddr=11.11.111.111 lport=123 exe=\"/usr/sbin/sshd\" hostname=? addr=11.111.111.11 terminal=? res=success'"
I'd like to extract the fields laddr, addr, and lport. I created a patterns directory with the following structure
patterns
|
-- laddr
|
-- addr
My filter is written like so
filter {
grok {
patterns_dir => ["./patterns"]
match => { "messaage" => "%{LADDR:laddr} %{ADDR:addr}"}
}
}
I was expecting to extract at least laddr and addr. I get matches using https://grokdebug.herokuapp.com/. With these patterns
(?<laddr>\b(laddr=\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})\b)
(?<addr>\b(addr=\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})\b)
but the configuration fails to compile. I'm just going off of these docs: https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html. I've also tried using a kv filter the issue that I run into when I try to use something like
filter{
kv {
value_split => "="
}
}
I end up with msg field showing up twice. I'd really like to figure out how to get the properties from this string. Any help would be greatly appreciated.
I think its field split :
filter {
kv {
field_split => "&?"
}
}
Did you try this, are you getting any error messages?
Logstash multiline codec ignore my last event (line) until send next package of logs.
My logstash.conf:
input {
}
http {
port => "5001"
codec => multiline {
pattern => "^\[%{TIMESTAMP_ISO8601}\]"
negate => true
what => previous
auto_flush_interval => 15
}
}
}
filter{
grok {
match => { "message" => "(?m)\[%{TIMESTAMP_ISO8601:timestamp}\]\s\<%{LOGLEVEL:log-level}\>\s\[%{WORD:component}\]\s%{GREEDYDATA:log-message}"
}
}
output {
elasticsearch {
hosts => "elasticsearch:9200"
index => "%{+YYYY-MM-dd}"
}
}
Moreover solution with auto_flush_interval don't work.
For example:
input using Postman:
[2017-07-11 22:32:12.345] [KCU] Component initializing
Exception in thread "main" java.lang.NullPointerException
at com.example.myproject.Book.getTitle(Book.java:16)
[2017-07-11 22:32:16.345] [KCU] Return with status 1
output - only one event (should be two):
[2017-07-11 22:32:12.345] [KCU] Component initializing
Exception in thread "main" java.lang.NullPointerException
at com.example.myproject.Book.getTitle(Book.java:16)
I need this last line.
Question:
Am I doing something wrong or there are problems with multiline codec? - How to fix this?
I'm afraid you're using the multiline codec wrong. Let's take a look at your configuration:
codec => multiline {
pattern => "^\[%{TIMESTAMP_ISO8601}\]"
negate => true
what => previous
}
It says if a logline does not (negate => true) start with a ISO timestamp (pattern) append it to the previous log line (what => previous).
But the logline you're missing starts with a ISO timestamp:
[2017-07-11 22:32:16.345] [KCU] Return with status 1
So it will not be appended to the previous log lines but instead create a new document in Elasticsearch.
I have configured ELK successfully for Laravel app, But we are facing issue with Laravel log. I have configured logstash template with below code. but I am receiving Break line in Kibana. I have tried two different configuration code as per below details.
20-laravel.conf
input {
stdin{
codec => multiline {
pattern => "^\["
what => "previous"
negate => true
}
}
}
filter {
grok {
match => { "message" => "\[%{TIMESTAMP_ISO8601:timestamp}\] %{DATA:env}\.%{DATA:severity}: %{DATA:message}" }
}
}
output {
elasticsearch {
document_type => "logs"
hosts => ["127.0.0.1"]
index => "laravel_logs"
}
}
filter {
# Laravel log files
if [type] == "laravel" {
grok {
match => { "message" => "\[%{TIMESTAMP_ISO8601:timestamp}\] %{DATA:env}\.%{DATA:severity}: %{DATA:message} \[" }
}
}
}
laravel sample log is :
[2017-09-13 16:19:28] production.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Parse error: syntax error, unexpected identifier (T_STRING), expecting ',' or ')' in /var/www/app/Http/Controllers/BrandsController.php:57
Stack trace:
#0 /var/www/vendor/composer/ClassLoader.php(322):
Composer\Autoload\includeFile('/var/www/vendor...')
#1 [internal function]: Composer\Autoload\ClassLoader-
>loadClass('App\\Http\\Contro...')
#2 [internal function]: spl_autoload_call('App\\Http\\Contro...')
So my main issue is we are reciveing this log in kibana in single line. for example above log code is a divided in different line message and we can't figure out that which line message is from which error?
Kibana log output for single laravel log is displayed in below image.kibana log-output
An easy alternative is to use Laralog.
With Laralog it is possible to Laravel logs directly to Elastic Search without install all the full Logstash stack, so it is suitable for small and container environments.
Example of usage:
laralog https://elasticsearch:9200 --input=laravel.log
Laralog will parse and send the logs automatically.
You should create a new provider to setup monolog properly, try the following setup:
class LogstashProvider extends ServiceProvider
{
public function boot(): void
{
$stream = storage_path('logs/laravel.log');
$name = env('APP_NAME');
$formatter = new LogstashFormatter($name, null, null, 'ctxt_', LogstashFormatter::V1);
$streamHandler = new StreamHandler($stream, Logger::DEBUG, false);
$streamHandler->setFormatter($formatter);
Log::getMonolog()->pushHandler(
$streamHandler
);
}
}
You also should configure your logstash to parse json instead
I try to match the loglevel of a log file with a grok filter, but still getting a _grokparsefailure. The problem is maybe with the space between [ and the log level.
example of log: 2017-04-21 10:12:03,004 [ INFO] Message
my filter:
filter {
grok {
match => {
"log.level" => "\[ %{LOGLEVEL:loglevel}\]"
}
}
}
I also tried some other solutions without success:
"\[ *%{LOGLEVEL:loglevel}\]"
"\[%{SPACE}%{LOGLEVEL:loglevel}\]"
Thanks in advance for your help
The issue is with the option match in your filter: this option is a hash that tells the filter which field to look at and which field to look at.
Your regex is fine (you can check with http://grokconstructor.appspot.com/do/match), the issue is with the field name; it should be message.
So in your case, your filter should look like this:
grok {
match => {
"message" => "\[ %{LOGLEVEL:loglevel}\]"
}
}
The point is the default field is message and you need to match all the string
filter {
grok {
match => {
"message" => "%{TIMESTAMP_ISO8601:logDate} \[ %{LOGLEVEL:loglevel}\]%{GREEDYDATA:messages}"
}
}
}
After parsing logs I am find there are some new lines at the end of the message
Sample message
ts:2016-04-26 05-02-16-018
CDT|ll:TRACE|tid:10000.140|scf:xxxxxxxxxxxxxxxxxxxxxxxxxxx.pc|mn:null|fn:xxxxxxxxxxxxxxxxxxxxxxxxxxx|ln:749|auid:xxxxxxxxxxxxxxxxxxxxxxxxxxx|eid:xxx.xxx.xxx.xxx-58261618-1-1461664935955-139|cid:900009865|ml:null|mid:-99|uip:xxx.xxx.xxx.xxx|hip:xxx.xxx.xxx.xxx|pli:null|msg:
xxxxxxxxxxxxxxxxxxxxxxxxxxx|pl: xxxxxxxxxxxxxxxxxxxxxxxxxxx
TAKE 1 xxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxx
I am using the regex pattern below as suggested below as answers
ts:(?(([0-9]+)-)+ ([0-9]+-)+ [A-Z]+)\|ll:%{WORD:ll}\|tid:%{NUMBER:tid}\|scf:%{DATA:scf}\|mn:%{WORD:mn}\|fn:%{WORD:fn}\|ln:%{WORD:ln}\|auid:%{WORD:auid}\|eid:%{DATA:eid}\|cid:%{WORD:cid}\|ml:%{WORD:ml}\|mid:%{NUMBER:mid}\|uip:%{DATA:uip}\|hip:%{DATA:hip}\|pli:%{WORD:pli}\|\smsg:%{GREEDYDATA:msg}(\|pl:(?(.|\r|\n)))
But unfortunately it is not working properly when the last part of the log is not present
ts:2016-04-26 05-02-16-018
CDT|ll:TRACE|tid:10000.140|scf:xxxxxxxxxxxxxxxxxxxxxxxxxxx.pc|mn:null|fn:xxxxxxxxxxxxxxxxxxxxxxxxxxx|ln:749|auid:xxxxxxxxxxxxxxxxxxxxxxxxxxx|eid:xxx.xxx.xxx.xxx-58261618-1-1461664935955-139|cid:900009865|ml:null|mid:-99|uip:xxx.xxx.xxx.xxx|hip:xxx.xxx.xxx.xxx
What should be the correct pattern?
-------------------Previous Question --------------------------------------
I am trying to parse log line such as this one.
ts:2016-04-26 05-02-16-018 CDT|ll:TRACE|tid:10000.140|scf:xxxxxxxxxxxxxxxxxxxxxxxxxxx.pc|mn:null|fn:xxxxxxxxxxxxxxxxxxxxxxxxxxx|ln:749|auid:xxxxxxxxxxxxxxxxxxxxxxxxxxx|eid:xxx.xxx.xxx.xxx-58261618-1-1461664935955-139|cid:900009865|ml:null|mid:-99|uip:xxx.xxx.xxx.xxx|hip:xxx.xxx.xxx.xxx|pli:null|msg: xxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxx
Below is my logstash filter
filter {
grok {
match => ["mesage", "ts:(?<date>(([0-9]+)-*)+ ([0-9]+-*)+ [A-Z]+)\|ll:%{WORD:ll}\|tid:%{WORD:tid}\|scf:%{WORD:scf}\|mn:%{WORD:mn}\|fn:%{WORD:fn}\|ln:%{WORD:ln}\|auid:%{WORD:auid}\|eid:%{WORD:eid}\|cid:%{WORD:cid}\|ml:%{WORD:ml}\|mid:%{WORD:mid}\|uip:%{WORD:uip}\|hip:%{WORD:hip}\|pli:%{WORD:pli}\|msg:%{WORD:msg}"]
}
date {
match => ["ts","yyyy-MM-dd HH-mm-ss-SSS ZZZ"]
target => "#timestamp"
}
}
I am getting "_grokparsefailure"
I have tested the configuration from #HAL, there was a few things to change:
In the grok filter mesage => message
In the date filter ts => date so the date parsing is on the right field
The CDT is a time zone name, it is captured by z in the date syntax.
So the right configuration would look like this :
filter{
grok {
match => ["message", "ts:(?<date>(([0-9]+)-*)+ ([0-9]+-*)+ [A-Z]+)\|ll:%{WORD:ll}\|tid:%{NUMBER:tid}\|scf:%{DATA:scf}\|mn:%{WORD:mn}\|fn:%{WORD:fn}\|ln:%{WORD:ln}\|auid:%{WORD:auid}\|eid:%{DATA:eid}\|cid:%{WORD:cid}\|ml:%{WORD:ml}\|mid:%{NUMBER:mid}\|uip:%{DATA:uip}\|hip:%{DATA:hip}\|pli:%{WORD:pli}\|\s*msg:%{GREEDYDATA:msg}"]
}
date {
match => ["date","yyyy-MM-dd HH-mm-ss-SSS z"]
target => "#timestamp"
}
}
Tried to parse your input via grokdebug with your expression but it failed to read out any fields. Managed to get it to work by changing the expression to:
ts:(?<date>(([0-9]+)-*)+ ([0-9]+-*)+ [A-Z]+)\|ll:%{WORD:ll}\|tid:%{NUMBER:tid}\|scf:%{DATA:scf}\|mn:%{WORD:mn}\|fn:%{WORD:fn}\|ln:%{WORD:ln}\|auid:%{WORD:auid}\|eid:%{DATA:eid}\|cid:%{WORD:cid}\|ml:%{WORD:ml}\|mid:%{NUMBER:mid}\|uip:%{DATA:uip}\|hip:%{DATA:hip}\|pli:%{WORD:pli}\|\s*msg:%{GREEDYDATA:msg}
I also think that you need to change the name of the column that logstash shall parse from mesage to message.
Also, the date parsing pattern should match the format of the date in the input. There is no timezone identity (ZZZ) in your input data (at least not in the example).
Something like this should work better (not tested though):
filter {
grok {
match => ["mesage", "ts:(?<date>(([0-9]+)-*)+ ([0-9]+-*)+ [A-Z]+)\|ll:%{WORD:ll}\|tid:%{NUMBER:tid}\|scf:%{DATA:scf}\|mn:%{WORD:mn}\|fn:%{WORD:fn}\|ln:%{WORD:ln}\|auid:%{WORD:auid}\|eid:%{DATA:eid}\|cid:%{WORD:cid}\|ml:%{WORD:ml}\|mid:%{NUMBER:mid}\|uip:%{DATA:uip}\|hip:%{DATA:hip}\|pli:%{WORD:pli}\|\s*msg:%{GREEDYDATA:msg}"]
}
date {
match => ["ts","yyyy-MM-dd HH-mm-ss-SSS"]
target => "#timestamp"
}
}
