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.

Sample log
{datetime":"2021-08-10 04:11:37,825","servername":"VM-0001","serverip":"(null)","process":"2404","thread":"4","level":"DEBUG","appname":"Dev-Email","page":"Program.cs"}
Given the sample document your shared, your elasticsearch output needs to look like this:
elasticsearch {
hosts => ["localhost:9200"]
index => "%{appname}-logs"
}
Also know that index names are not allowed to contain uppercase letters, so Dev-Email will need to be lowercased (using the mutate/lowercase filter) before being used as the index name.
My question is related to logstash grok pattern. I created below pattern that's working fine but the big problem is not string values. Sometimes; "Y" and "age" can be null so my grok pattern not create any log in elasticseach. It is not working properly. I need to tell my grok pattern :
if(age is null || age i empty){
updatefield["age",0]
}
but I don't know how to make it. by the way; I checked many solutions by googling but it is directly related to my problem.

You can check if your fields exists or are empty using conditionals with your filter,
filter {
if ![age] or [age] == "" {
mutate {
update => { "age" => "0" }
}
}
}
I am trying to use file as an input to logstash.Here is my logstash.conf
input {
file {
path => "/home/dxp/elb.log"
type => "elb"
start_position => "beginning"
sincedb_path => "/home/dxp/log.db"
}
}
filter {
if [type] == "elb" {

}
}
}

manage_template => false
index => "elblog-%{+YYYY.MM.dd}"

}
}
My logs show this:
[2017-10-27T13:11:31,164][DEBUG][logstash.inputs.file ]_globbed_files: /home/dxp/elb.log: glob is []: I guess my file has not been read by logstash, so a new index is not formed in elasticsearch.
Please help me with what i am missing in this.
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.
i have duplicate data in Logstash
how could i remove this duplication?
my input is:
input
input {
file {
path => "/var/log/flask/access*"
type => "flask_access"
max_open_files => 409599
}
stdin{}
}
filter
filter of files is :
filter {
mutate { replace => { "type" => "flask_access" } }
grok {
match => { "message" => "%{FLASKACCESS}" }
}
mutate {
add_field => {
"temp" => "%{uniqueid} %{method}"
}
}
if "Entering" in [api_status] {
aggregate {
task_id => "%{temp}"
code => "map['blockedprocess'] = 2"
map_action => "create"
}
}
if "Entering" in [api_status] or "Leaving" in [api_status]{
aggregate {
task_id => "%{temp}"
code => "map['blockedprocess'] -= 1"
map_action => "update"
}
}
if "End Task" in [api_status] {
aggregate {
task_id => "%{temp}"
code => "event['blockedprocess'] = map['blockedprocess']"
map_action => "update"
end_of_task => true
timeout => 120
}
}
}
Take a look at the image, the same data log, at the same time, and I just sent one log request.
i solve it
i create a unique id by ('document_id') in output section
document_id point to my temp and temp is my unique id in my project
my output changed to:
output {
elasticsearch {
hosts => ["localhost:9200"]
document_id => "%{temp}"
# sniffing => true
# manage_template => false
# index => "%{[#metadata][beat]}-%{+YYYY.MM.dd}"
# document_type => "%{[#metadata][type]}"
}
stdout { codec => rubydebug }
}
Executing tests in my local lab, I've just found out that logstash is sensitive to the number of its config files that are kept in /etc/logstash/conf.d directory.
If config files are more than 1, then we can see duplicates for the same record.
So, try to remove all backup configs from /etc/logstash/conf.d directory and perform logstash restart.
