I want to use this filter to math first line in my follow log
grok {
match => {
#"message" => '^(?<test>\d{4}[-]\d{2}[-]\d{2}[ ]\d{2}[:]\d{2}[:]\d{2}).*$'
"message" => "(?<log_date>\d{4}[-]\d{2}[-]\d{2}[ ]\d{2}[:]\d{2}[:]\d{2})([ ].+[ ])(%{LOGLEVEL:log_level})(?<log_header>[ ]+.+[M][s][g][=])(%{GREEDYDATA:log_info})"
}
}

This regex works well in grok debugger,but has different output in logstash.
I want result like this
{
"log_date": [
[
"2021-10-22 08:34:12"
]
],
"log_level": [
[
"ERROR"
]
],
"log_header": [
[
" com.winning.ias.fhir.inpat.service.win60.impl.WinFhirServiceImpl - Msg="
]
],
"log_info": [
[
"{"msgId":"3935de4a-6d5a-411a-860a-729eea0f263c","msgType":"BusinessException","eventDesc":"","info":""}"
]
]
}
but actually result is this
{
"log_date": [
[
"2021-10-22 08:34:12"
]
],
"log_level": [
[
"ERROR"
]
],
"log_header": [
[
" com.winning.ias.fhir.inpat.service.win60.impl.WinFhirServiceImpl - Msg="
]
],
"log_info": [
[

]
]
}
The actually output just like (?m)%{GREEDYDATA:log_info},but there is no "?m" in my regex

Consider the below string
date 00:00 1.1.1.1 POST test.com hello-world
How could I print only the date totaltime and URL(test.com) using grok?
Given the sample above
^%{DATA:date} %{DATA:time} %{IP:ip} %{DATA:method} %{DATA:url} %{GREEDYDATA:path}$
would generate:
{
"date": [
[
"date"
]
],
"time": [
[
"00:00"
]
],
"ip": [
[
"1.1.1.1"
]
],
"method": [
[
"POST"
]
],
"url": [
[
"test.com"
]
],
"path": [
[
"hello-world"
]
]
}
Afterwards you can mutate it whichever form you want
Here is my sample URL
http://localhost:8080/abc2/query/errorLogs
was trying to extract only query/errorLogs. For this i have tried below GROK patten
(%{URIPROTO}://%{URIHOST}(?<path>/[^/]+/[^/]+/[^/]+))
Below output i am getting
{
"URIPROTO": [
[
"http"
]
],
"URIHOST": [
[
"localhost:8080"
]
],
"IPORHOST": [
[
"localhost"
]
],
"HOSTNAME": [
[
"localhost"
]
],
"IP": [
[
null
]
],
"IPV6": [
[
null
]
],
"IPV4": [
[
null
]
],
"port": [
[
"8080"
]
],
"path": [
[
"/abc2/query/errorLogs"
]
]
}
but i was expecting path should be "/query/errorLogs".
try this :
(%{URIPROTO}://%{URIHOST}(?<first_path>/[^/]+)%{GREEDYDATA:path})
result:
port 8080
first_path /abc2
path /query/errorLogs
This is the sample log pattern I'm parsing. I'm using grok but it's not exactly as what I expected
180528 8:46:26 2 Query SELECT 1
To parse this log my grok pattern is
%{NUMBER:date} %{NOTSPACE:time}%{INT:pid}%{GREEDYDATA:message}
and output for this in grok debugger is
> { "date": [
> [
> "180528"
> ] ], "time": [
> [
> "8:46:2"
> ] ], "pid": [
> [
> "6"
> ] ], "message": [
> [
> " 2 Query\tSELECT 1"
> ] ] }
If you observe in the output, pid is being extracted from time and actual pid which is 2 is being merged in the message. Not sure what went wrong here.
Why can't you just match your time with TIME pattern instead? it doesn't make sense to match it with NOTSPACE which equals to \S+, and matches any non-whitespace character (equal to [^\r\n\t\f\v ])
You can use TIME pattern for your time value and INT for pid as follows,
%{NUMBER:date}\s%{TIME:time}\s%{INT:pid}\s%{GREEDYDATA:message}
This will give you,
{
"date": [
[
"180528"
]
],
"BASE10NUM": [
[
"180528"
]
],
"time": [
[
"8:46:26"
]
],
"HOUR": [
[
"8"
]
],
"MINUTE": [
[
"46"
]
],
"SECOND": [
[
"26"
]
],
"pid": [
[
"2"
]
],
"message": [
[
"Query SELECT 1"
]
]
}
I have been trying to parse a sample log file using logstash grok filter but was unable to output the distinguish fields.
my sample logs look like following-
INFO [2016-05-26 11:54:57,741] [main]: org.eclipse.jetty.util.log:?:?- Logging initialized #5776ms`enter code here`
what i want to separate out is INFO, timestamp ,[main] and the message in two parts from from ?:?.
what pattern i have tried in grok filter is ->
match => { "message" => "%{WORD:severity}
%{CISCOTIMESTAMP:timestamp} %{NOTSPACE} %{GREEDYDATA:logmsg}" }
but its not correctly output the pattern.
can please someone provide me the correct grok pattern match!!
Any related help would be useful!!
As it is not clear what exact format do you want to get, I provide you with following filter:
match => { "message" => "%{LOGLEVEL:severity} *\[%{TIMESTAMP_ISO8601:timestamp}\] *\[%{WORD:tread}\]\: *%{NOTSPACE:file} *%{GREEDYDATA:msg}" }
This will effectively split your example to:
{
"severity": [
[
"INFO"
]
],
"timestamp": [
[
"2016-05-26 11:54:57,741"
]
],
"YEAR": [
[
"2016"
]
],
"MONTHNUM": [
[
"05"
]
],
"MONTHDAY": [
[
"26"
]
],
"HOUR": [
[
"11",
null
]
],
"MINUTE": [
[
"54",
null
]
],
"SECOND": [
[
"57,741"
]
],
"ISO8601_TIMEZONE": [
[
null
]
],
"tread": [
[
"main"
]
],
"file": [
[
"org.eclipse.jetty.util.log:?:?-"
]
],
"msg": [
[
"Logging initialized #5776ms`enter code here`"
]
]
}
This doesn't gracefully parse :?:?- part, so adjust it if needed.
Take a look at Grokdebug which is great for on-the-fly filter testing.
My logs look as such
00009139 2015-03-03 00:00:20.142 5254 11607 "HTTP First Line: GET /?main&legacy HTTP/1.1"
I tried using grok debugger to get this information formatted with no success. Is there any way to get this format using grok? The quoted string would be the message
So I used the following formatting simply by using the grok patterns page.
%{NUMBER:Sequence} %{YEAR}-%{MONTHNUM}-%{MONTHDAY}[T ]%{HOUR}:?%{MINUTE}(?::?%{SECOND})?%{ISO8601_TIMEZONE}? %{NUMBER:Process}%{NUMBER:Process2}%{WORD:Message}
This is the closest I could get with the current info.
%{INT}%{SPACE}%{TIMESTAMP_ISO8601}%{SPACE}%{INT:pid1}%{SPACE}%{INT:pid2}%{SPACE}%{GREEDYDATA:message}
With the above grok pattern, this is what the grokdebugger "catches":
{
"INT": [
[
"00009139"
]
],
"SPACE": [
[
" ",
" ",
" ",
" "
]
],
"TIMESTAMP_ISO8601": [
[
"2015-03-03 00:00:20.142"
]
],
"YEAR": [
[
"2015"
]
],
"MONTHNUM": [
[
"03"
]
],
"MONTHDAY": [
[
"03"
]
],
"HOUR": [
[
"00",
null
]
],
"MINUTE": [
[
"00",
null
]
],
"SECOND": [
[
"20.142"
]
],
"ISO8601_TIMEZONE": [
[
null
]
],
"pid1": [
[
"5254"
]
],
"pid2": [
[
"11607"
]
],
"message": [
[
""HTTP First Line: GET /?main&legacy HTTP/1.1""
]
]
}
Hope I was of some help.
Try to replace %{WORD:Message} at the end of your grok with %{QS:message}.
hope this helps :)
