I have the following logstash grok statements that should run if the field contains a string "Caused" in which case a different pattern is applied to it and it is overwritten but for some reason it does work. The regex patterns definitely work individually and the issue is in the the logic below. Any help appreciated, thanks
grok {
patterns_dir => ["./patterns"]
match => ["message", "%{GREEDYDATA}\n%{JAVA_EXCEPTION_SHORT:exception}"]
}
if [exception] =~ "Caused" {
grok {
patterns_dir => ["./patterns"]
match => ["exception", "{JAVA_EXCEPTION_LONG:exception}"]
overwrite => ["exception"]
}
}
Custom Patterns:
JAVA_EXCEPTION_LONG (?<=^Caused by: ).*?Exception
JAVA_EXCEPTION_SHORT ^.+Exception

The grok filter fails because you're missing a % in this line:
match => ["exception", "{JAVA_EXCEPTION_LONG:exception}"]
It should look like this:
match => ["exception", "%{JAVA_EXCEPTION_LONG:exception}"]
Since the parsing failed, the field exception was not overwritten.

I´m trying to extract the number of ms in this logline
20190726160424 [INFO]
[concurrent/forasdfMES-managedThreadFactory-Thread-10] -
Metricsdceptor: ## End of call: Historirrtory.getHistrrOrder took 2979
ms
The problem is, that not all loglines contain that string
Now I want to extract it optionally into a duration field. I tried this, but nothing happend .... no error, but also no result.
grok
{
match => ["message", "(took (?<duration>[\d]+) ms)?"]
}
What I´m I doing wrong ?
Thanks guys !
A solution would be to only apply the grok filter on the log lines ending with ms. It can be done using conditionals in your configuration.
if [message] =~ /took \d+ ms$/ {
grok {
match => ["message", "took %{NUMBER:duration} ms"]
}
}
I cannot explain why, but it works if you anchor it
grok { match => { "message" => "(took (?<duration>\d+) ms)?$" } }
Here is my log
INLFCW1MQ2.enterprisenet.org 11:55:57.818 [main] INFO GeneratorApplication - application 1 sample log
And here is the grok pattern in logstash
filter {
grok {
match => { "message" => "%{SYSLOGHOST:hostname}\s+%{TIME}\s+\[(?<threadname>[^\]]+)\]\s+%{LOGLEVEL:loglevel}\s+%{GREEDYDATA:message}" }
}
}
Pattern passed in grok debugger but fails in logstash. I have added white space after seeing this thread,
Grok pattern works in Grok Debugger but not in logstash
try this:
%{SYSLOGHOST:hostname} %{TIME:time} \[%{WORD:threadname}\] %{LOGLEVEL:loglevel} %{GREEDYDATA:message}
sometimes I got errors due to the (?
So here is a sample of my log:

I have to parse this logs into following fields: timestamp, log-level, logger, msg, stacktrace.
i have used the multiline filter:
multiline {
pattern => "%{TIME:timestamp}"
negate => true
what => “previous”
}
and the pattern i used in grok filter:
match=>{"message"=>"%{TIME:timestamp} %{LOGLEVEL:loglevel} \s*\[%{DATA:logger}\]\s*%{GREEDYDATA:msg}\n*(?<stacktrace>(.|\r|\n)*)"}
i have checked it with http://grokconstructor.appspot.com/do/match. but got this matching error for stacktrace field.
please do suggest some suggestions.
thanks in advance.
You will need a multiline filter if you want to match the whole stacktrace. This multiline filter should work for you:
codec => multiline {
pattern => "^%{TIME} "
negate => true
what => previous
}
Explanation: Every line not starting with a timestamp (like 23:28:32.226) will be regocnized as part of the previous line. See also the docs on dealing with multilines.
Now to your pattern. Following works for me:
%{TIME:timestamp} %{LOGLEVEL:loglevel} \[%{DATA:logger}\] %{GREEDYDATA:message}\n(?<stacktrace>(.|\r|\n)*)
Pretty self explaining, I hope:
Escaping braces like [ and ] with \[ and \], \n to match the newline. Also note the spaces between the entries.
For the last part (stacktrace) also see this question on how to match everything including newlines.
A full configuration could look something like this:
input {
file {
path => "/var/log/yourlog.log"
start_position => "beginning"
codec => multiline {
pattern => "^%{TIME} "
negate => true
what => previous
}
}
}
filter {
grok {
match => [ "message", "%{TIME:timestamp} %{LOGLEVEL:loglevel} \[%{DATA:logger}\] %{GREEDYDATA:message}\n(?<stacktrace>(.|\r|\n)*)" ]
}
}
Results on http://grokconstructor.appspot.com:
2017-08-09T12:01:43.049963+05:30 55.3.244.1 11235 GET
This is my log data.
I am trying to filter this data using custom patterns. I am getting "_grokparsefailure" error.
my pattern file data isTIMESTAMP_LOG [0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{6}\+[0-9]{2}:[0-9]{2}
my filter is:
filter {
grok {
patterns_dir => ["./patterns"]
match => { "message" => "%{TIMESTAMP_LOG:time} %{IP:client} %{NUMBER:bytes} %{WORD:method}" }
} }
can anyone help me where i am done wrong.Thanks.
Your timestamp is actually of a standard format - ISO8601. So instead of having your custom pattern for timestamp, you can use one built into Logstash instead. I tested this grok pattern and it worked with your sample log:
%{TIMESTAMP_ISO8601:time} %{IP:client} %{NUMBER:bytes} %{WORD:method}
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"
}
}
