I have grok filter for apache logs as follows :
if [type] == "apachelogs" {
grok {
break_on_match => false
match => { "message" => "\[%{HTTPDATE:apachetime}\]%{SPACE}%{NOTSPACE:verb}%{SPACE}/%{NOTSPACE:ApacheRequested}" }
match=> { "message" => "\*\*%{NUMBER:seconds}/%{NUMBER:microseconds}" }
add_tag => "%{apachetime}"
add_tag => "%{verb}"
add_tag => "%{ApacheRequested}"
add_tag => "%{seconds}"
add_tag => "%{microseconds}"
I want to create a visualisation in kibana for search type="apachelogs". O am using filebeat.So my search query is
filebeat*type="apachelogs"
I want apachetime in X-axis and microseconds in Y-axis.But in Y
-axis, I am not getting any fields except default ones (sum,count,aggregation).
Please help.I dont know what I am doing wrong.

I use filebeat to fetch log files into my logstash and then filter unnecessary fields. Everything works fine and I output these into elasticsearch but there is a field which I use for elasticsearch index name, I define this variable in my grok match but I couldn't find a way to remove that variable once it serves its purpose. I'll share my logstash config below
input {
beats {
port => "5044"
}
}
filter {
grok {
match => { "[log][file][path]" => ".*(\\|\/)(?<myIndex>.*)(\\|\/).*.*(\\|\/).*(\\|\/).*(\\|\/).*(\\|\/)" }
}
json {
source => message
}
mutate {
remove_field => ["agent"]
remove_field => ["input"]
remove_field => ["#metadata"]
remove_field => ["log"]
remove_field => ["tags"]
remove_field => ["host"]
remove_field => ["#version"]
remove_field => ["message"]
remove_field => ["event"]
remove_field => ["ecs"]
}
date {
match => ["t","yyyy-MM-dd HH:mm:ss.SSS"]
remove_field => ["t"]
}
mutate {
rename => ["l","log_level"]
rename => ["mt","msg_template"]
rename => ["p","log_props"]
}
}
output {
elasticsearch {
hosts => [ "localhost:9222" ]
index => "%{myIndex}"
}
stdout { codec => rubydebug { metadata => true } }
}
I just want to remove the "myIndex" field from my index. With this config file, I see this field in elasticsearch if possible I want to remove it. I've tried to remove it with other fields altogether but it gave an error. I guess it's because I removed it before logstash could give it to elasticsearch.
Create the field under [#metadata]. Those fields are available to use in logstash but are ignored by outputs unless they use a rubydebug codec.
Adjust your grok filter
match => { "[log][file][path]" => ".*(\\|\/)(?<[#metadata][myIndex]>.*)(\\|\/).*.*(\\|\/).*(\\|\/).*(\\|\/).*(\\|\/)" }
Delete [#metadata] from the mutate+remove_field and change the output configuration to have
index => "%{[#metadata][myIndex]}"
i could see some events are missing while reporting logs to elastic search. Take an example i am sending 5 logs event only 4 or 3 are reporting.
Basically i am using logstash 7.4 to read my log messages and store the information on elastic search 7.4. below is my logstash configuration
input {
file {
type => "web"
path => ["/Users/a0053/Downloads/logs/**/*-web.log"]
start_position => "beginning"
sincedb_path => "/tmp/sincedb_file"
codec => multiline {
pattern => "^(%{MONTHDAY}-%{MONTHNUM}-%{YEAR} %{TIME}) "
negate => true
what => previous
}
}
}
filter {
if [type] == "web" {
grok {
match => [ "message","(?<frontendDateTime>%{MONTHDAY}-%{MONTHNUM}-%{YEAR} %{TIME})%{SPACE}(\[%{DATA:thread}\])?( )?%{LOGLEVEL:level}%{SPACE}%{USERNAME:zhost}%{SPACE}%{JAVAFILE:javaClass} %{USERNAME:orgId} (?<loginId>[\w.+=:-]+#[0-9A-Za-z][0-9A-Za-z-]{0,62}(?:[.](?:[0-9A-Za-z][0-9A-Za-z-]{0,62}))*) %{GREEDYDATA:jsonstring}"]
}
json {
source => "jsonstring"
target => "parsedJson"
remove_field=>["jsonstring"]
}
mutate {
add_field => {
"actionType" => "%{[parsedJson][actionType]}"
"errorMessage" => "%{[parsedJson][errorMessage]}"
"actionName" => "%{[parsedJson][actionName]}"
"Payload" => "%{[parsedJson][Payload]}"
"pageInfo" => "%{[parsedJson][pageInfo]}"
"browserInfo" => "%{[parsedJson][browserInfo]}"
"dateTime" => "%{[parsedJson][dateTime]}"
}
}
}
}
output{
if "_grokparsefailure" in [tags]
{
elasticsearch
{
hosts => "localhost:9200"
index => "grokparsefailure-%{+YYYY.MM.dd}"
}
}
else {
elasticsearch
{
hosts => "localhost:9200"
index => "zindex"
}
}
stdout{codec => rubydebug}
}
As keep on new logs are writing to log files, i could see a difference of log counts.
Any suggestions would be appreciated.
I have logstash with ElasticSearch & Kibana 7.6.2
I connect logstash to Kafka as follows:
input {
kafka {
bootstrap_servers => "******"
topics_pattern => [".*"]
decorate_events => true
add_field => { "[topic_name]" => "%{[#metadata][kafka][topic]}"}
}
}
filter {
date {
match => [ "timestamp", "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "logstash"
document_type => "logs"
}
}
It's OK and work. But I field topic_name show as %{[#metadata][kafka][topic]}
How can I fix it?
The syntax of the sprintf format you are using ( %{[#metadata][kafka][topic]} ) to get the value of that field is correct.
Allegedly there is no such field #metadata.kafka.topic in your document. Therefore the sprintf can't obtain the field value and as a result, the newly created field contains the sprintf call as a string.
However, since you set decorate_events => true, the metadata fields should be available as stated in the documentation (https://www.elastic.co/guide/en/logstash/current/plugins-inputs-kafka.html):
Metadata is only added to the event if the decorate_events option is set to true (it defaults to false).
I can imagine that the add_field action set in the input plugin causes the issue. Since the decorate_events option first enables the addition of the metadata fields, the add_field action should come at second place after the input plugin.
Your configuration would then look like this:
input {
kafka {
bootstrap_servers => "******"
topics_pattern => [".*"]
decorate_events => true
}
}
filter {
mutate{
add_field => { "[topic_name]" => "%{[#metadata][kafka][topic]}"}
}
date {
match => [ "timestamp", "dd/MMM/yyyy:HH:mm:ss Z" ]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "logstash"
document_type => "logs"
}
}
How about
add_field => { "topic_name" => "%{[#metadata][kafka][topic]}"}
i.e. [topic_name] -> topic_name
The input is comma separated values:
"2010-08-19","09:12:55","56095675"
I created the custom date_time field which appears to right format 2010-08-19;09:12:55 but not matching.
filter {
grok {
match => { "message" => '"(%{GREEDYDATA:cust_date})","(%{TIME:cust_time})","(%{NUMBER:author})"'}
add_field => {
"date_time" => "%{cust_date};%{cust_time}"
}
}
date {
match => ["date_time", "yyyy-MM-dd;hh:mm:ss"]
target => "#timestamp"
add_field => { "debug" => "timestampMatched"}
}
Output on Kibana:
cust_date August 18th 2010, 20:00:00.000
cust_time 09:12:55
date_time 2010-08-19;09:12:55
message "2010-08-19","09:12:55","56095675"
tags beats_input_codec_plain_applied, _dateparsefailure
It gives _dateparsefailure. The fields appear to be same as match pattern.
I tried different time format like YYYY-MM-dd;hh:mm:ss and YYYY-MM-dd;HH:mm:ss
What am I doing wrong?
Help!
You should put the date plugin inside the filter section, right under grok.
filter {
grok {
match => { "message" => '"(%{GREEDYDATA:cust_date})","(%{TIME:cust_time})","(%{NUMBER:author})"'}
add_field => {
"date_time" => "%{cust_date};%{cust_time}"
}
date {
match => ["date_time", "yyyy-MM-dd;hh:mm:ss"]
target => "#timestamp"
add_field => { "debug" => "timestampMatched"}
}
}
I have the following configuration for logstash.
There are 3 parts to this one is a generallog which we use for all applications they land in here.
second part is the application stats where in which we have a specific logger which will be configured to push the application statistics
third we have is the click stats when ever an event occurs on client side we may want to push it to the logstash on the upd address.
all 3 are udp based, we also use log4net to to send the logs to the logstash.
the base install did not have a GeoIP.dat file so got the file downloaded from the https://dev.maxmind.com/geoip/legacy/geolite/
have put the file in the /opt/logstash/GeoIPDataFile with a 777 permissions on the file and folder.
second thing is i have a country name and i need a way to show how many users form each country are viewing the application in last 24 hours.
so for that reason we also capture the country name as its in their profile in the application.
now i need a way to get the geo co-ordinates to use the tilemap in kibana.
What am i doing wrong.
if i take the geoIP { source -=> "country" section the logstash works fine.
when i check the
/opt/logstash/bin/logstash -t -f /etc/logstash/conf.d/logstash.conf
The configuration file is ok is what i receive. where am i going worng?
Any help would be great.

As per the error message, the mutation which you're trying to do could be wrong. Could you please change your mutate as below:
mutate {
convert => { "geoip" => "float" }
convert => { "coordinates" => "float" }
}
I guess you've given the mutate as an array, and it's a hash type by origin. Try converting both the values individually. Your database path for geoip seems to be fine in your filter. Is that the whole error which you've mentioned in the question? If not update the question with the whole error if possible.
Refer here, for in depth explanations.
