I'm new with ELK stack. I need to parse my customlogs using Grok and then analyze them.
[11/Oct/2018 09:51:47] INFO [serviceManager.management.commands.serviceManagerMonitor:serviceManagerMonitor.py:114] [2018-10-11 07:51:47.527997+00:00] SmMonitoring Module : Launching action info over the service sysstat is delayed
with this grok pattern:
\[(?<timestamp>%{MONTHDAY}\/%{MONTH}\/%{YEAR} %{TIME})\] %{LOGLEVEL:loglevel} \[%{GREEDYDATA:messagel}\] \[%{GREEDYDATA:message2}\] %{GREEDYDATA:message3}
i tried a grok debugger and it's matched
here is the configuration of logstash for the input:
input {
beats {
port => 5044
}
}
and here is the output configuration:
output {
elasticsearch {
hosts => ["localhost:9200"]
sniffing => true
manage_template => false
index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
document_type => "%{[#metadata][type]}"
}
}
and here is the whole filter:
filter {
grok {
match => { "message" => "\[(?<timestamp>%{MONTHDAY}\/%{MONTH}\/%{YEAR} %{TIME})\] %{LOGLEVEL:loglevel} \[%{GREEDYDATA:messagel}\] \[%{GREEDYDATA:message2}\] %{GREEDYDATA:message3}" }
}
date {
match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
but i don't get any result with elasticsearch.
Thank you for helping me.

I am trying to config a filebeat with logstash. At the moment I managed to successfully config filebeat with logstash and I am running into same issues when creating multiple conf files in the logstash.
So currently I have one filebeats input which is something like :
input {
beats {
port => 5044
}
}
filter {
}
output {
if [#metadata][pipeline] {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "systemsyslogs"
pipeline => "%{[#metadata][pipeline]}"
}}
else {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "systemsyslogs"
}
}}
And a file Logstash config which is like :
input {
file {
path => "/var/log/foldername/number.log"
start_position => "beginning"
}
}
filter {
grok {
match => { "message" => "%{WORD:username} %{INT:number} %{TIMESTAMP_ISO8601:timestamp}" }
}
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
index => "numberlogtest"
}
}
The grok filter is working as I successfully managed to create 2 index patterns in kibana and view the data correctly.
The problem is that when I am running logstash with both configs applied, logstash is fetching the data from number.log multiple times and logstash plain logs are getting lots of warning, therefore using a lot of computing resources and CPU is going over 80% ( this is an oracle instance ). If I remove the file config from logstash the system is running properly.
I managed to run logstash with each one of these config files applied individually, but not both at once.
I already added an exception in the filebeats config :
exclude_files:
- /var/log/foldername/*.log
Logstash plain logs when running both config files:
[2023-02-15T12:42:41,077][WARN ][logstash.outputs.elasticsearch][main][39aca10fa204f31879ff2b20d5b917784a083f91c2eda205baefa6e05c748820] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"numberlogtest", :routing=>nil}, {"service"=>{"type"=>"system"}
"caused_by"=>{"type"=>"illegal_state_exception", "reason"=>"Can't get text on a START_OBJECT at 1:607"}}}}}
I already added an exception in the filebeat config :
exclude_files:
- /var/log/foldername/*.log
Fixed by creating a single logstash config with both inputs :
input {
beats {
port => 5044
}
file {
path => "**path**"
start_position => "beginning"
}
}
filter {
if [path] == "**path**" {
grok {
match => { "message" => "%{WORD:username} %{INT:number} %{TIMESTAMP_ISO8601:timestamp}" }
}
}
}
output {
if [#metadata][pipeline] {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "index1"
pipeline => "%{[#metadata][pipeline]}"
}
} else {
if [path] == "**path**" {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "index2"
}
} else {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "index1"
}
}
}
}
I am absolutely new to Logstash and I am trying to parse my multiline logentries, that are in the following format
<log level="INFO" time="Wed May 03 08:25:03 CEST 2017" timel="1493792703368" host="host">
<msg><![CDATA[Method=GET URL=http://localhost (Vers=[Version], Param1=[param1], Param2=[param1]) Result(Content-Length=[22222], Content-Type=[text/xml; charset=utf-8]) Status=200 Times=TISP:1098/CSI:-/Me:1/Total:1099]]>
</msg>
</log>
Do you know how to implement the filter in logstash config to be able to index the following fields in elasticsearch
time, host, Vers, Param1, Param2, TISP
Thank you very much
OK, I found out how to do it. This is my pipeline.conf file and it works
input {
beats {
port => 5044
}
}
filter {
xml {
store_xml => false
source => "message"
xpath => [
"/log/#level", "level",
"/log/#time", "time",
"/log/#timel", "unixtime",
"/log/#host", "host_org",
"/log/#msg", "msg",
"/log/msg/text()","msg_txt"
]
}
grok {
break_on_match => false
match => ["msg_txt", "Param1=\[(?<param1>-?\w+)\]"]
match => ["msg_txt", "Param2=\[(?<param2>-?\w+)\]"]
match => ["msg_txt", "Vers=\[(?<vers>-?\d+\.\d+)\]"]
match => ["msg_txt", "TISP:(?<tisp>-?\d+)"]
match => [unixtime, "(?<customTime>-?\d+)"]
}
if "_grokparsefailure" in [tags] {
drop { }
}
mutate {
convert => { "tisp" => "integer" }
}
date {
match => [ "customTime", "UNIX_MS"]
target => "#timestamp"
}
if "_dateparsefailure" in [tags] {
drop { }
}
}
output {
elasticsearch {
hosts => "elasticsearch:9200"
user => user
password => passwd
}
}
How to create a grok custom pattern filter in logstash?
I want to create a pattern for http response status code
here is my pattern code
STATUS_CODE __ %{NONNEGINT} __
what I reaaly want to do is to have all of my web server hits with user IP and request http headers and payload and also web servers's response.
and here is my logstash.conf
input {
file {
type => "kpi-success"
path => "/var/log/kpi_success.log"
start_position => beginning
}
}
filter {
if [type] == "kpi-success" {
grok {
patterns_dir => ["./patterns"]
match => { "message" => "%{TIMESTAMP_ISO8601:timestamp} %{GREEDYDATA:message} "}
}
multiline {
pattern => "^\["
what => "previous"
negate => true
}
mutate{
add_field => {
"statusCode" => "[STATUS_CODE]"
}
}
}
}
output {
if [type] == "kpi-success" {
elasticsearch {
hosts => "elasticsearch:9200"
index => "kpi-success-%{+YYYY.MM.dd}"
}
}
}
You don't have to use a custom pattern file, you can define a new one directly in the filter.
grok {
match => { "message" => "(?<STATUS_CODE>__ %{NONNEGINT} __)"}
}
My logstash filter correct in debugger but doesn't show the fields when searching the exact message I tested with in kibana. Here is my filter:
filter {
if [type] == "syslog" {
grok {
match => { 'message' => '%{SYSLOG5424LINE}' }
}
syslog_pri {
syslog_pri_field_name => 'syslog5424_pri'
}
date {
match => [ 'syslog5424_ts', 'ISO8601' ]
}
}
and here is an example of my log message:
<134>1 2017-01-23T10:54:44.587136-08:00 mcmp mapp - - close ('xxx', 32415)
It seems like the filter isn't applying, I restarted my logstash service and tested in the grok debugger. Any idea whats wrong?
It looks like it works correctly to me.
I created test.conf with:
input {
stdin {}
}
filter {
grok {
match => { 'message' => '%{SYSLOG5424LINE}' }
}
syslog_pri {
syslog_pri_field_name => 'syslog5424_pri'
}
date {
match => [ 'syslog5424_ts', 'ISO8601' ]
}
}
output {
stdout { codec => "rubydebug" }
}
and then tested like this:
echo "<134>1 2017-01-23T10:54:44.587136-08:00 mcmp mapp - - close ('xxx', 32415)" | bin/logstash -f test.conf
And the event it gives as output:
{
"syslog_severity_code" => 6,
"syslog_facility" => "local0",
"syslog_facility_code" => 16,
"syslog5424_ver" => "1",
"message" => "<134>1 2017-01-23T10:54:44.587136-08:00 mcmp mapp - - close ('xxx', 32415)",
"syslog5424_app" => "mapp",
"syslog5424_msg" => "close ('xxx', 32415)",
"syslog_severity" => "informational",
"tags" => [],
"#timestamp" => 2017-01-23T18:54:44.587Z,
"syslog5424_ts" => "2017-01-23T10:54:44.587136-08:00",
"syslog5424_pri" => "134",
"#version" => "1",
"host" => "xxxx",
"syslog5424_host" => "mcmp"
}
which has all of the fields that the SYSLOG5424LINE pattern contains.
I have a syslog server and the ELK stack on the same server. I have a directory for each syslog source.
I'm trying to parse syslog files with Logstash, and I'd like to keep the ip adress or the hostname of the syslog source in the "host" field. At the moment I have the 0.0.0.0 source after Logstash parsing.
My logstash.conf :
input {
file {
path => ["path/to/file.log"]
start_position => "beginning"
type => "linux-syslog"
ignore_older => 0
}
}
filter {
if [type] == "linux-syslog" {
grok {
match => {"message" => "<%{POSINT:syslog_pri}>%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:[%{POSINT:syslog_pid}])?: %{GREEDYDATA:syslog_message}" }
}
}
}
output {
elasticsearch {
hosts => ["#IP_Elastic:Port_Elastic"]
}
stdout { codec => rubydebug }
}
you can overwrite your host with your ip variable once you have parsed it. Consider this example:
Pipeline main started
{"ip":"1.2.3.4"}
{
"message" => "{\"ip\":\"1.2.3.4\"}",
"#version" => "1",
"#timestamp" => "2016-08-10T13:36:18.875Z",
"host" => "pandaadb",
"ip" => "1.2.3.4",
"#host" => "1.2.3.4"
}
I am parsing json to get the IP. Then I write the IP field into the host.
The filter:
filter {
# this parses the ip json
json {
source => "message"
}
mutate {
add_field => { "#host" => "%{ip}" }
}
}
replace %{ip} with whatever field contains your ip address.
Cheers,
