I use input file to get logs like this:
input {
file {
path => "/home/ec2-user/*.log"
}
}
In one of the log files some events are loging with 1 line:
2018-12-10 10:01:30.1097|0|Services.Services|INFO| Message: test
Another are multilines like this one :
2018-12-10 10:01:30.1097|0|Services.Services|INFO| Message: {
"account_id": "ec812648-3857-4625-9d9a-fc8ce1835493",
"name": "Player_539017",
"creation_time": "10/12/2018 10:52:52",
"hq_level": 2,
"force": 2570
} successfully dequeued |url: |action:
How can I capture both of the messages with logstash filter:
Below is an example from this page which uses the multiline codec to capture log lines starting with a date timestamp as single event. This will work for both of the log events mentioned above.
file {
path => "/home/ec2-user/*.log"
codec => multiline {
# Grok pattern names are valid
pattern => "^%{TIMESTAMP_ISO8601} "
negate => true
what => "previous"
}
}

I'd need to collect metrics from an URL. The format of the metrics is like that:
# HELP base:classloader_total_loaded_class_count Displays the total number of classes that have been loaded since the Java virtual machine has started execution.
# TYPE base:classloader_total_loaded_class_count counter
base:classloader_total_loaded_class_count 23003.0
I'd need to exclude, from the events collected, all lines which begin with a '#' character.
So I have arranged for the following configuration file:
input {
http_poller {
urls => {
pool_metrics => {
method => "get"
url => "http://localhost:10090/metrics"
headers => {
"Content-Type" => "text/plain"
}
}
}
request_timeout => 30
schedule => { cron => "* * * * * UTC"}
codec => multiline {
pattern => "^#"
negate => "true"
what => previous
}
type => "server_metrics"
}
}
output {
elasticsearch {
# An index is created for each type of metrics inpout
index => "logstash-%{type}"
}
}
Unfortunately, when I check through elastic search the data collected, I see it's not really what I was expecting. For example:
{
"_index" : "logstash-server_metrics",
"_type" : "doc",
"_id" : "2egAvWcBwbQ9kTetvX2o",
"_score" : 1.0,
"_source" : {
"type" : "server_metrics",
"tags" : [
"multiline"
],
"message" : "# TYPE base:gc_ps_scavenge_count counter\nbase:gc_ps_scavenge_count 24.0",
"#version" : "1",
"#timestamp" : "2018-12-17T16:30:01.009Z"
}
},
So it seems that the lines with '#' aren't skipped but appended to the next line from the metrics.
Can you recommend any way to fix it?
The multiline codec doesn't work this way. It merges the events into a single event, appending the lines that don't match ^# as you have observed.
I don't think it's possible to drop messages with a codec, you'll have to use the drop filter instead.
First remove the codec from your input configuration, then add this filter part to your configuration:
filter {
if [message] =~ "^#" {
drop {}
}
}
Using conditionals, if the message matches ^#, the event will be dropped by the drop filter, as you wanted.
I am just new to logstash trying to import apache log file into Elastic - I see the below error:
RROR] 2017-10-28 00:38:51.085 [LogStash::Runner] agent - Cannot create pipeline {:reason=>"Expected one of #, {, } at line 4, column 19 (byte 81) after input {\nfile {\npath =>\"/home/monus/logstash-tutorial-dataset“\nstart_position =>\""}
here is my logstash.conf file
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}" }
}
date {
match => [ "timestamp", "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
That's logstash's way of telling you it found a syntax error on line 4, character 19 of the config-file. As line 4 in your snippet is a close-bracket, and you have no input {} bracket at all in the snippet, I'd look in your input section for the syntax error.
I am pretty new to logstash and I have been trying to convert an existing log into a csv format using the logstash-output-csv plugin.
My input log string looks as follows which is a custom log written in our application.
'128.111.111.11/cpu0/log:5988:W/"00601654e51a15472-76":687358:<9>2015/08/18 21:06:56.05: comp/45 55% of memory in use: 2787115008 bytes (change of 0)'
I wrote a quick regex and added it to the patterns_dir using the grok plugin.
My pattern is as follows :
IP_ADDRESS [0-9,.]+
CPU [0-9]
NSFW \S+
NUMBER [0-9]
DATE [0-9,/]+\s+[0-9]+[:]+[0-9]+[:]+[0-9,.]+
TIME \S+
COMPONENT_ID \S+
LOG_MESSAGE .+
without adding any csv filters I was able to get this output.
{
"message" => "128.111.111.11/cpu0/log:5988:W/"00601654e51a15472-76":687358:<9>2015/08/18 21:06:56.05: comp/45 55% of memory in use: 2787115008 bytes (change of 0)",
"#version" => "1",
"#timestamp" => "2015-08-18T21:06:56.05Z",
"host" => "hostname",
"path" => "/usr/phd/raveesh/sample.log_20150819000609",
"tags" => [
[0] "_grokparsefailure"
]
}
This is my configuration in order to get the csv as an output
input {
file {
path => "/usr/phd/raveesh/temporary.log_20150819000609"
start_position => beginning
}
}
filter {
grok {
patterns_dir => "./patterns"
match =>["message", "%{IP_ADDRESS:ipaddress}/%{CPU:cpu}/%{NSFW:nsfw}<%{NUMBER:number}>%{DATE}:%{SPACE:space}%{COMPONENT_ID:componentId}%{SPACE:space}%{LOG_MESSAGE:logmessage}" ]
break_on_match => false
}
csv {
add_field =>{"ipaddress" => "%{ipaddress}" }
}
}
output {
# Print each event to stdout.
csv {
fields => ["ipaddress"]
path => "./logs/firmwareEvents.log"
}
stdout {
# Enabling 'rubydebug' codec on the stdout output will make logstash
# pretty-print the entire event as something similar to a JSON representation.
codec => rubydebug
}
}
The above configuration does not seem to give the output. I am trying only to print the ipaddress in a csv file but finally I need to print all the captured patterns in a csv file. so I need the output as follows :
128.111.111.111,cpu0,nsfw, ....
Could you please let me know the changes i need to make. ?
Thanks in advance
EDIT:
I fixed the regex as suggested using the tool http://grokconstructor.appspot.com/do/match#result
Now my regex filter looks as follows :
%{IP:client}\/%{WORD:cpu}\/%{NOTSPACE:nsfw}<%{NUMBER:number}>%{YEAR:year}\/%{MONTHNUM:month}\/%{MONTHDAY:day}%{SPACE:space}%{TIME:time}:%{SPACE:space2}%{NOTSPACE:comp}%{SPACE:space3}%{GREEDYDATA:messagetext}
How do I capture the individual splits and save it as a csv ?
Thanks
EDIT:
I finally resolved this using the File plugin .
output {
file{
path => "./logs/sample.log"
message_pattern =>"%{client},%{number}"
}
}
The csv tag in the filter section is for parsing the input and exploding the message to key/value pairs.
In your case you are already parsing the input with the grok, so I bet you don't need the csv filter.
But in the output we can see there is a gorkfailure
{
"message" => "128.111.111.11/cpu0/log:5988:W/"00601654e51a15472-76":687358:<9>2015/08/18 21:06:56.05: comp/45 55% of memory in use: 2787115008 bytes (change of 0)",
"#version" => "1",
"#timestamp" => "2015-08-18T21:06:56.05Z",
"host" => "hostname",
"path" => "/usr/phd/raveesh/sample.log_20150819000609",
"tags" => [
[0] "****_grokparsefailure****"
]
}
That means your grok expression cannot parse the input.
You should fix the expression according to your input and then the csv will output properly.

BTW, are you sure the patterns NSFW, CPU, COMPONENT_ID, ... are defined somewhere ?

I'm trying with logstash to collect data from a log file for a version of NETASQ Firewall which contains a lot of lines , but i can not collect correctly my data , I don't know if there is a standard to follow, but I started like this:
input {
stdin { }
file {
type => "FireWall"
path => "/var/log/file.log"
start_position => 'beginning'
}
}
filter {
grok {
match => [ "message", "%{SYSLOGTIMESTAMP:date} %{WORD:id}"]
}
}
output {
stdout { }
elasticsearch {
cluster => "logstash"
}
}
The first line of my file.log looks like this :
Feb 27 04:02:23 id=firewall time="2015-02-27 04:02:23" fw="GVGM-NEWYORK"
tz=+0200 startime="2015-02-27 04:02:22" pri=5 confid=01 slotlevel=2 ruleid=57

dstportname=teredo dstname=teredo.ipv6.microsoft.com.nsatc.net

And finally How can I collect data from the others lines. Please give me a topic just to start. Thanks All.
I am receiving Log4j generated log files from remote servers using Logstash forwarder. The log event has fields including a field named "file" in the format /tomcat/logs/app.log, /tomcat/logs/app.log.1, etc. Of course file path /tomcat/logs is on the remote machine and I would like Logstash to create files on the local file system using only the file name and not use the remote file path.
Locally, I would like to create a file based on file name app.log, app.log.1, etc. How can one accomplish this?
I am unable to use grok since it appears to work only with "message" field and not others.
Example Log Event:
{"message":["11 Sep 2014 16:29:04,934 INFO LOG MESSAGE DETAILS HERE "],"#version":"1","#timestamp":"2014-09-15T05:44:43.472Z","file":["/tomcat/logs/app.log.1"],"host":"aus-002157","offset":"3116","type":"app.log"}
Logstash configuration - what do I use to write the filter section?
input {
lumberjack {
port => 48080
ssl_certificate => "/tools/LogStash/logstash-1.4.2/ssl/logstash.crt"
ssl_key => "/tools/LogStash/logstash-1.4.2/ssl/logstash.key"
}
}
filter{
}
output {
file{
#message_format => "%{message}"
flush_interval => 0
path => "/tmp/%{host}.%{type}.%{filename}"
max_size => "4M"
}
}
Figured out the pattern to be as follows:
grok{
match => [ "file", "^(/.*/)(?<filename>(.*))$" ]
}
Thanks for the help!
Logstash Grok can parse all the fields in a log event, not only message field.
For example, you want to extract the file field,
you can do like this
filter {
grok {
match => [ "file", "your pattern" ]
}
}
