How I can use GROK in this case?
It seems like it's not possible to apply grok to this

I need to find grok pattern for files where the lines are of the format :
3 dbm.kfa 0 340220 7766754 93.9
3 swapper/3 0 340220 7766754 93.9
This is the grok pattern that I have done so far.
\s*%{INT:no1}\s*%{USERNAME:name}\s*%{INT:no2}\s*%{INT:no3}\s*%{INT:no4}\s*%{GREEDYDATA:ans}
The field USERNAME works for dbm.kfa but not for swapper/3 as USERNAME does not include \ character. I would like to create some custom filter for this purpose, but have no idea how to create one.
Any help would be really appreciated. Thanks a lot !
To create a custom pattern you need to use an external file in the following format and put that file in a directory the will be used only for pattern files.
PATTERN_NAME [regex for your pattern]
Then you will need to change your grok config to point to the pattern files directory.
grok {
patterns_dir => ["/path/to/patterns/dir"]
match => { "message" => "%{PATTERN_NAME:fieldName}" }
}
But in your specific case if you change %{USERNAME:name} to %{DATA:name} it should work.
For a better explanation about the custom patterns you should read this part of the documentation.
You also can find all the core grok patterns that ships with logstash in this github repository, the most used are in the grok-patterns file.
Basically I was setting up an Elasticsearch-Logstash-Kibana (elk) stack for monitoring syslogs. Now I have to write the grok pattern for logstash.
Here's an example of my log:
May 8 15:14:50 tileserver systemd[25780]: Startup finished in 29ms.
And that's my pattern (yet):
%{SYSLOGTIMESTAMP:zeit} %{HOSTNAME:host} %{SYSLOGPROG:program}
Usually I'm also using %{DATA:text} for the message but it just works on the link below.
I'm using Test grok patterns to test my patterns and these 3 work fine but there's the colon (from after PID) in front of the message and I don't want it to be there.
How do I get rid of it?
try this:
%{SYSLOGTIMESTAMP:zeit} %{HOSTNAME:host} %{GREEDYDATA:syslog_process}(:) %{GREEDYDATA:message}
Can anyone give the logstash grok pattern for below lines. I want to take only timestamp alone.
[2017-08-19T12:47:43,822][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600}
[2017-08-19T12:49:47,213][WARN][logstash.agent] stopping pipeline {:id=>"main"}
I'm not sure to understand what you want but here are two possible solutions:
[%{GREEDYDATA:date1}][%{LOGLEVEL:debugLevel}][%{USERNAME:agentName}] %{GREEDYDATA:message} [%{TIMESTAMP_ISO8601:date2}][%{LOGLEVEL:debugLevel2}][%{USERNAME:agentName2}] %{GREEDYDATA:message}
This grok pattern will extract all information that you have in your log, then you decide if you want to use date1 or date2 field
%{GREEDYDATA:trash}[%{TIMESTAMP_ISO8601:date}]%{GREEDYDATA:trash}
This one will only return the second date of your log
Hope it helped !
If you only need the timestamp, this should do:
\[%{TIMESTAMP_ISO8601:date}\]
Results for your two loglines on https://grokconstructor.appspot.com:
If you want to match the whole pattern something like this may fit your needs:
\[%{TIMESTAMP_ISO8601:date}\]\[%{LOGLEVEL:loglevel}\]\[%{GREEDYDATA:agent}\] %{GREEDYDATA:message}
Results:
I'm trying to figure out how it works logstash and grok to parse messages. I have found that example ftp://ftp.linux-magazine.com/pub/listings/magazine/185/ELKstack/configfiles/etc_logstash/conf.d/5003-postfix-filter.conf
which start like this:
filter {
# grok log lines by program name (listed alpabetically)
if [program] =~ /^postfix.*\/anvil$/ {
grok{...
But don't understand where [program] is parsed. I'm using logstash 2.2
That example are not working in my logstash installation, nothing is parsed.
I answer myself.
The example assumes that the events come from syslog (in that case the field "program" are present), instead filebeats which is what I'm using to send the events to logstash.
To fix-it:

We are in the process of capturing the logstash

we are having logs like this,We want how to match the messages .Once matched we want to remove 82745269 and [http-nio-10180-exec-609].Pls help
How do you match them? With the grok filter.
How do you make a grok pattern? Slowly, using the debugger.
Maybe an introduction would help.
