I want to convert logstash date type to this type 2015-12-03 03:01:00 and [message][3] - [message][1]
Date match doesn't work, how can I do?
Or %{[message][0]} expression is right or not.
filter {
multiline {
.............
}
grok {
match => { "message" => "%{GREEDYDATA:message}" }
overwrite => ["message"]
}
mutate {
gsub => ["message", "\n", " "]
split => ["message", " "]
}
date {
match => [ "%{[message][0]}","ISO8601"} ]
}
}
Message output like this:
"message" => [
[0] "2015-12-03T01:33:22+00:00"
[1]
[2]
[3] "2015-12-03T01:33:24+00:00"
]
Assuming your input is:
2015-12-03T01:33:22+00:00\n\n2015-12-03T01:33:24+00:00
You can grok that without split:
match => { message, "%{TIMESTAMP_ISO8601:string1}\\n\\n%{TIMESTAMP_ISO8601:string2}" }
You can then use the date{} filter with string1 or string2 as input.

I can't parse a date field using the logstash date plugin, my config is as follow:
if "test" in [tags] {
csv {
separator => ","
columns => [ "value", "received_date" ]
convert => {
"value" => "float"
}
}
mutate {
gsub => [ "received_date" , ".\d*$" , ""]
}
date {
match => [ "received_date", "yyyy-MM-dd HH:mm:ss" ]
}
}
I get the error:
[2018-06-19T11:51:20,583][WARN ][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>"f2d34d84-1ea4-4510-8237-2329a4d1ffba",
:_index=>"logstash-2018.06.19", :_type=>"doc", :_routing=>nil}, #], :response=>{"index"=>{"_index"=>"logstash-2018.06.19", "_type"=>"doc", "_id"=>"f2d34d84-1ea4-4510-8237-2329a
4d1ffba", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse [received_date]", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"Invalid format: \"2018-06-19 11:51:15\" is malformed at \" 11:51:15\""}}}}}
If I add a target:
date {
match => [ "received_date", "yyyy-MM-dd HH:mm:ss" ]
target => "received_date"
}
Then it works, but the timestamp field takes the date logstash received the input, which is not what I want.
Why would the target impact the date parsing ?
timestamp field is mapped as date in elasticsearch for some reason.
You can delete the timestamp field,
date {
locale => "en"
remove_field => ["timestamp"]
}
I am just a newbie to the ELK and trying some testing on this, i'm able to run some tests but while i'm trying a filter with grok & mutate to remoev & replace some feilds from my syslog output i'm getting into below error..
21:58:47.976 [LogStash::Runner] ERROR logstash.agent - Cannot create pipeline {:reason=>"Expected one of #, {, ,, ] at line 21, column 9 (byte 496) after filter {\n if [type] == \"syslog\" {\n grok {\n match => { \"message\" => \"%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:hostname} %{DATA:program}(?:\\[%{POSINT:pid}\\])?: %{GREEDYDATA:syslog_message}\" }\n }\n date {\n match => [ \"syslog_timestamp\", \"MMM d HH:mm:ss\", \"MMM dd HH:mm:ss\" ]\n }\n mutate {\n remove_field => [\n \"message\",\n \"pid\",\n \"port\"\n "}
Below is my config file ....
# cat logstash-syslog2.conf
input {

filter {

}
mutate {
remove_field => [
"message",
"pid",
"port"

]
}
mutate {
replace => [
"#source_host", "%{allLogs_hostname}"

}
}
output {

elasticsearch {
hosts => "localhost:9200"
index => "%{type}-%{+YYYY.MM.dd}"
}
}
}
please suggest what i'm doing wrong and help to understand the remove & replace functions for the lagstash..
PS: my ELK version is 5.4
The Config you posted have lot of syntactical errors , the logsatsh has it's own config language and expects the config file to abide by the rule.
This link has complete logstash config language reference.
I made some corrections to your config file and posted here , Have added my comments and explanation of what was wrong in the config file itself
input
{
file
{
path => [ "/scratch/rsyslog/*/messages.log" ]
type => "syslog"
}
}
filter
{
if [type] == "syslog"
{
grok
{
match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:hostname} %{DATA:program}(?:\[%{POSINT:pid}\])?: %{GREEDYDATA:syslog_message}" }
}
date
{
match => [ "syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss" ]
}
# Have merged it with the remove_field option below
#mutate {
# remove_field => [

{
# The replace option only accept hash data type which has a syntax as below
# For more details visit the below link

}
}
mutate
{
# Mutate does not have remove option i guess your intention is to remove the event field

remove_field => [
"message",
"pid",
"port",
"_grokparsefailure",
"allLogs_hostname",
"syslog_message",
"syslog_timestamp"
]
}
}
}
output
{
if [type] == "syslog"
{
elasticsearch
{
# The Hosts option only takes uri as a value type , originally you have provided string as it's value type
# For more info please read the below link
#https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts
hosts => ["localhost:9200"]
index => "%{type}-%{+YYYY.MM.dd}"
}
}
}
You can test whether the config file is syntactically correct by using logstash command line option -t this option will test and report the config file is syntactically correct
bin\logstash -f 'path-to-your-config-file' -t
Please let me know for any clarification
You have to add a comma after "port" in your logstash configuration file.
mutate {
remove_field => [
"message",
"pid",
"port",
"_grokparsefailure"
]
}
I am trying to input a timestamp field in Logstash and i am getting dateparsefailure message.
My Message -
2014-08-01;11:00:22.123
Pipeline file
input {
stdin{}
#beats {
# port => "5043"
# }
}
# optional.
filter {
date {
locale => "en"
match => ["message", "YYYY-MM-dd;HH:mm:ss.SSS"]
target => "#timestamp"
add_field => { "debug" => "timestampMatched"}
}
}
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
}
stdout { codec => rubydebug }
}
Can someone tell me what i am missing ?
Update 1
I referred to the link - How to remove trailing newline from message field and now it works.
But, in my log message, i have multiple values other than timestamp
<B 2014-08-01;11:00:22.123 Field1=Value1 Field2=Value2
When i give this as input, it is not working. How to read a part of the log and make it as timestamp ?
Update 2
it works now.
Changed the config file as below
filter {
kv
{
}
mutate {
strip => "message"
}
date {
locale => "en"
match => ["timestamp1", "YYYY-MM-dd;HH:mm:ss.SSS"]
target => "#timestamp"
add_field => { "debug" => "timestampMatched"}
}
}
I am posting the answer below and steps i used to solve the issue so that i can help people like me.
Step 1 - I read the message in the form of key and value pair
Step 2 - I trimmed off the extra space that leads to parse exception
Step 3 - I read the timestamp value and other fields in respective fields.
input {
beats {
port => "5043"
}
}
# optional.
filter {
kv { }
date {
match => [ "timestamp", "yyyy-MM-dd HH:mm:ss,SSS" ]
remove_field => [ "timestamp" ]
}
}
output {
elasticsearch {
hosts => [ "127.0.0.1:9200" ]
}
}
i'm triyng to monitor an irc server. And i'm loot for a way to create a new numeral field (example: Alert_level) only if a message match a specific word inside.
Example: Message: ABC | Alert_level: 1 ; Message: ZYX | Alert_level: 3.
Its the running code
input {
irc {
channels => "#xyz"
host => "a.b.c"
nick => "myusername"
catch_all => true
get_stats => true
}
}
output {
stdout { codec => "rubydebug" }
elasticsearch {
hosts => "localhost"
index => "logstash-irc-%{+YYYY.MM.dd}"
}
}
Thank you!
As #Val suggested above you might need to use the grok filter in order match something from the input. For example your filter could look something like this:
filter {
grok {
match => { "message" => "%{GREEDYDATA:somedata}" }
}
if "ZYX" in [message]{ <-- change your condition accordingly
mutate {
add_field => { "%{Alert_level}" => "12345" } <-- somefield is the field name
convert => { "Alert_level" => "integer" } <-- do the conversion
}
}
}
NOTE that you have to do the conversion in order to create a numeric field through logstash, where you can't directly create one. The above is just a sample so that you can reproduce. Do change the grok match in respect to your requirement. Hope it helps!
I just started with Logstash parsing a CSV document. CSV document only has two columns "Date" and "High". I have read various configurations to parse a date but I can not, giving me error in that field. The date has the format DD / MM / YYYY and error tells me the following:
Failed parsing date from field {:field=>"Date", :value=>"Date", :exception=>"Invalid format: \"Date\"", :config_parsers=>"dd/MM/YYYY", :config_locale=>"default=es_ES", :level=>:warn}
This is my configuration file to filter Logstash:
input {
file {
path => "/path/to/data.csv"
start_position => "beginning"
}
}
filter {
csv {
separator => ","
columns => ["Date","High"]
}
date{
match => [ "Date", "dd/MM/YYYY" ]
}
mutate {convert => ["High", "float"]}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
action => "index"
index => "machine"
workers => 1
}
stdout { codec => rubydebug }
}
Thank you!!
In your date plugin try to change the letter cases in the match setting. Something like this:
date{
match => [ "Date", "DD/MM/YYYY" ]
}
If not helping try to make them all lowercase.
The format string dd/MM/yyyy should work. You can find detailed specifications for formatting strings in the JodaTime documentation.
