For some reason filebeat is not sending the correct logs while using the multiline filter in the filebeat.yml file. The log file im reading has some multiline logs, and some single lines. However, they all follow the same format by starting with a date. For an example, here is a couple lines:
2017-Aug-23 10:33:43: OutputFile: This is a sample message
2017-Aug-23 10:34:23: MainClass: Starting connection:
http.InputProcess: 0
http.OutPutProcess: 1
2017-Aug-23 10:35:21: OutputFile: This is a sample message 2
My Filebeat yml is:
- input_type: log
paths:
- /home/user/logfile.log
document_type: chatapp
multiline:
pattern: "^%{YYYY-MMM-dd HH:mm:ss}"
negate: true
match: before
For some reason when i see the filebeat logs hit elasticsearch, all of the logs will be aggragated into one log line, so it does not seem to be actually reading the file date by date. Can Anyone help? Thanks!
Use
pattern: "^%{YEAR}-%{MONTH}-%{MONTHDAY}"
The pattern you are currently using there is not a validly defined regex given the grok patterns.
You can test multiline patterns using the grokconstructor. I constructed this pattern from the grok-patterns predefined in logstash.

I use Filebeat6x to ship my logs to logstash.
Some of my logs may be a multiline thats why I use Filebeat to Manage multiline messages
Now I want to add filter in logstash to do something like
if the message is multiline then add tag.
If the parsing of those multilines was from logstash I will use multliline_tag.
But how can I tag those multilines when the parsing is done in filebeat?
The following is a log sample I need to parse using logstash and the logstash grok filter:
2018-02-12 15:17:39.216 [DEBUG] [ 60] [CashTransactionReportCommand] [4564 456] - Xml of valid cash: <NewDataSet>
<Table>
<transaction_id>546464</transaction_id>
<device_trans_id>24</device_trans_id>
<value>3.5000</value>
<product_code>40</product_code>
<product_pa_code>E1</product_pa_code>
<catalog_number />
<decimal_place>2</decimal_place>
<site_id>2</site_id>
<machineSeTime>2018-02-12T17:17:39.273+00:00</machineSeTime>
<payment_method_id>3</payment_method_id>
<actor_id>4566</actor_id>
<operator_id>55</operator_id>
</Table>
</NewDataSet>
I almost have everything I need:
%{TIMESTAMP_ISO8601:log_timestamp} \[%{LOGLEVEL:loglevel}\] \[%{DATA:snId}\] \[%{WORD:snName}\] (?<test>\[\d+ \d+\]) %{GREEDYDATA:logmessage}
My only problem with the "logmessage". I need it to contain everything passed "[4564 456]" until the end of the example.
In order to be able to parse the message, including the XML, you'll have to group all the lines in the same logstash event, so that when using the grok filter, the message field contains the whole message. This can be done:
in logstash with the multiline codec
Multiline in logstash
Multiline codec documentation
in filebeat with the multiline option
Multiline in filebeat
Documentation of multiline option in filebeat configuration
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:
Hello and thank you for your time.
I need to create configuration file that this is the input:
2017-02-14T13:39:33+02:00 PulseSecure: 2017-02-14 13:39:33 - ive -
[10.16.4.225] dpnini(Users)[] - Testing Password realm restrictions
failed for dpnini/Users
and this is the required text file output:
{"timestamp":"2017-02-14T13:39:33+02:00
","vendor":"PulseSecure","localEventTime":"2017-02-14
13:39:33","userIP":"10.16.4.225","username":"dpnini","group":"Users","vpnMsg":"Testing
Password realm restrictions failed for dpnini/Users\r"}
All i know is that i start the logstash with "bin/logstash -f logstash-simple.conf"
also i know that the file that i need to change is YML file inside the config folder.
Thank you!
Logstash conf file (your logstash-simple.conf) is composed of three parts: input, filter, output. Input/output is source/destination of your data, while filter defines data transformation.
Check elastic page for samples:
https://www.elastic.co/guide/en/logstash/current/config-examples.html
What you actually need to do, is to write grok pattern inside filter to split your text into tokens/fields that you have in your json. Simple description of grok:

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:
