We have a logstash parsing script to parse the logfiles and we have written parsing script for the same. We are facing issue when trying to replace #timestamp with logfile time. Below is the filter that we have used
filter {
json {
source => "message"
target => "doc"
}
mutate {
copy => { "[doc][message]" => "mesg" }
copy => { "[doc][log][file][path]" => "logpath" }
remove_field => [ "[doc]" ]
}
if ( "/prodlogsfs/" not in [logpath] ) {
drop { }
}
if [logpath] {
dissect {
mapping => {
"logpath" => "%{deployment}deployment-%{?id}-%{?extra}"
}
}
}
grok { match => { "mesg" => [ "^\s?\[%{DATA:loglevel}\] %{TIMESTAMP_ISO8601:logts} \[%{DATA:threadname}\] %{DATA:podname} %{DATA:filler1} \[%{DATA:classname}\] %{GREEDYDATA:fullmesg}",
"(\s)+(?<exception>%{DATA}Exception)[:\s]+(?<trace>(%{DATA}at)+)"
]
} }
#Date Filter being used to replace #timestamp with logfile time
if [logts] {
date {
match => [ "logts", "ISO8601" ]
timezone => "Asia/Kolkata"
target => ["#timestamp"]
}
}
With the above code, when we check the value for #timestamp and logts in kibana, #timestamp shows the currenttime. Whereas the logts time seems to be a future time (+5.30) . Need help on how to match the #timestamp with logts.
Anyhelp on this is much appreciated. Thanks in Advance

I would like create a logstash grok pattern to parse the below oracle audit log and extract only the values from "<AuditRecord> to </AuditRecord>"
{"messageType":"DATA_MESSAGE","owner":"656565656566","logGroup":"/aws/rds/instance/stg/audit","logStream":"STG_ora_20067_20210906120520144010741320.xml","subscriptionFilters":["All logs"],"logEvents":[{"id":"36370952585791240628335082776414249187626811417307774976","timestamp":1630929920144,"message":<AuditRecord><Audit_Type>8</Audit_Type><EntryId>1</EntryId><Extended_Timestamp>2021-08-31T13:25:20.140969Z</Extended_Timestamp><DB_User>/</DB_User><OS_User>rdsdb</OS_User><Userhost>ip-172-27-1-72</Userhost><OS_Process>6773</OS_Process><Instance_Number>0</Instance_Number><Returncode>0</Returncode><OSPrivilege>SYSDBA</OSPrivilege><DBID>918393906</DBID> <Sql_Text>CONNECT</Sql_Text> </AuditRecord>"}]}
these logs are stored in s3 and in gz format. I am using below config for Logstash but its not working.
input {
s3 {
bucket => "s3bucket"
type => "oracle-audit-log-xml"
region => "eu-west-1"
}
}
filter {

if [type] == "oracle-audit-log-xml" {
mutate { gsub => [ "message", "[\n]", "" ] }
grok {

mutate {
add_field => { "audit_message" => "<AuditRecord>%{temp_audit_message}</AuditRecord>" }
}

target => "#timestamp"
}
# remove temporary fields
mutate { remove_field => ["message", "audit_message", "temp_audit_message"] }

}
}
it seems to be an issue with the line below
{"messageType":"DATA_MESSAGE","owner":"656565656566","logGroup":"/aws/rds/instance/stg/audit","logStream":"STG_ora_20067_20210906120520144010741320.xml","subscriptionFilters":["All logs"],"logEvents":[{"id":"36370952585791240628335082776414249187626811417307774976","timestamp":1630929920144,"message":
is there any way we can modify this to drop the above line.
Thanks
You don't need a grok pattern as your logs are in JSON format. Install logstash json filter plugin.
$ logstash-plugin install logstash-filter-json
And add filter setting to like below to parse your logs.
filter{
json {
source => "message"
}
}
Can check attached screenshot from my local ELK setup. Tried to parse log line provided by you.
And Thank you in advance for any help!
I'm using Netdata to collect metrics from servers and then send them to Logstash and to Elastic.
My need is to aggregate metrics with same fields and create a single event but in nested format.
This a example of input from Netdata:
{"host":"centosdns","#version":"1","port":52212,"#timestamp":"2019-01-19T16:16:22.117Z","message":"netdata.centosdns.disk_await.centos_swap.reads 0.0000000 1547914548"}
{"host":"centosdns","#version":"1","port":52212,"#timestamp":"2019-01-19T16:16:22.117Z","message":"netdata.centosdns.disk_await.centos_swap.writes 0.0000000 1547914548"}
{"host":"centosdns","#version":"1","port":52212,"#timestamp":"2019-01-19T16:16:22.117Z","message":"netdata.centosdns.disk_await.centos_root.reads 0.0000000 1547914548"}
{"host":"centosdns","#version":"1","port":52212,"#timestamp":"2019-01-19T16:16:22.117Z","message":"netdata.centosdns.disk_await.centos_root.writes 0.0000000 1547914548"}
My config file of logstash looks like:
input {
tcp {
port => 1234
}
}
filter {
# I take 'message' field and separate in different fields
grok {
named_captures_only => "true"
pattern_definitions => {
"CHART" => "[a-z]\w+"
"FAMILY" => "[_a-z0-9]+"
}
match => {
"message" => "%{WORD:prefix}\.%{WORD:hostname}\.%{CHART:chart}\.%{FAMILY:family}\.%{NOTSPACE:dimension} %{NUMBER:val} %{NUMBER:timestamp}"
}
}
if "_grokparsefailure" not in [tags] {
mutate {
remove_field => [ "#version", "host", "port", "prefix" ]
}
# Attempt to create a nested field and then aggregate
mutate {
id => "chart_field"
add_field => { "[%{chart}][%{family}][%{dimension}][value]" => "%{val}"
}
}
aggregate {
task_id => "[%{chart}][%{family}]"
code => "
# I tried many codes to aggregate but without success
event.cancel()
"
push_previous_map_as_event => true
timeout => 5
}
mutate {
# Remove unnecessary fields
id => "netdata_mutate_remove"
remove_field => [ "timestamp", "message"]
}
} else {
drop{}
}
output {
# TESTING PURPOSES
if "_aggregateexception" in [tags] {
file {
path => "/var/log/logstash/netdata/aggregatefailures-%{+MM-dd}.log"
}
} else {
file {
path => "/var/log/logstash/netdata/netdata-%{+MM-dd}-aggregate.log"
}
}
stdout { codec => rubydebug }
}
Take the input above:
"netdata.centosdns.disk_await.centos_swap.reads 0.0000000"
"netdata.centosdns.disk_await.centos_swap.writes 0.0000000"
My objective is make a nested field like:
disk_await: { # Chart
centos_swap: { # Family
[
reads => 0.0000000, # Dimension => Value
writes => 0.0000000 # Dimension => Value
]
}
}
I pretend to aggregate all 'Dimension\'Value'' in the same 'Chart'\'Family', this is only four lines of metrics but in reality we talk about 1000 per second or even more in some cases, all metrics are dynamic, it's virtual impossible to know all the names.
At this moment I'm using:
Logstash v.6.5.4 on a Virtualbox CentOS 7 minimal
All plugins (inputs/filters/outputs) updated
I noticed that #timestamp field, which is correctly defined by filebeat, is changed automatically by logstash and its value is replaced with a log timestamp value (field name is a_timestamp).
Here is part of logstash debug log:

NB:
I noticed that this doesn't happen with a simple pipeline (without grok, kv and other plugins I use in my custom pipeline)
I changed filebeat's property json.overwrite_keys to TRUE but with no success.
Can you explain me why and what happens with #_timestamp changing? I don't expect it to be done automatically (I saw many posts of people asking how to do that) because #timestamp is a system field.. What's wrong with that?
Here is my pipeline:
input {

Thank you very much,

This was the error (a typo from previous tests):
date {

}
Thank you guys, anyway!
I need to write the value of a UNIX timestamp field to #timestamp so that I can correctly index data flowing through logstash, I have this part working. However I also have the requirement that #timestamp's value should be the insertion time. To this end I have made a temporary field that holds #timestamps original value.
Here is what I am working with:
filter {
csv {
separator => " " # <- this white space is actually a tab, don't change it, it's already perfect
skip_empty_columns => true
columns => ["timestamp", ...]
}
# works just fine
mutate {
add_field => {
"tmp" => "%{#timestamp}"
}
}
# works just fine
date {
match => ["timestamp", "UNIX"]
target => "#timestamp"
}
# this works too
mutate {
add_field => {
"[#metadata][indexDate]" => "%{+YYYY-MM-dd}"
}
}
# #timestamp is not being set back to its original value
date {
match => ["tmp", "UNIX"]
target => "#timestamp"
}
# works just fine
mutate {
remove_field => ["tmp"]
}
}
output {
elasticsearch {
hosts => "elasticsearch:9200"
# this works
index => "indexname-%{[#metadata][indexDate]}"
}
}
The Problem is here:
date {
match => ["tmp", "UNIX"]
target => "#timestamp"
}
#timestamp is not being set back to its original value. When I check the data it has the same value as the timestamp field.
When you add the date to tmp, it gets added in ISO8601 format, so you need to use:
date {
match => ["tmp", "ISO8601"]
target => "#timestamp"
}
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.
