I have some problems while using logstash to opensearch.
filter{
grok {
patterns_dir => ["/etc/logstash/conf.d/patterns"]
match => [ "message","%{DATE_FORM:logdate}%{LOGTYPE:logtype}:%{SPACE}%{GREEDYDATA:msgbody}" ]
}
date {
match => ["logdate", "yyyy.MM.dd-HH.mm.ss:SSS"]
timezone => "UTC"
target=>"timestamp"
}
mutate {
remove_field => ["message"]
add_field => {
"file" => "%{[#metadata][s3][key]}"
}
}
}
This is the conf file I'm using for logstash.
In the opensearch console
#timestamp : Dec 15, 2022 # 18:10:56.975
logdate [2022.12.10-11.57.36:345]
tags _dateparsefailure
The timestamp , logdate are different and _dateparsefailure error occurs.
In the raw logs , it starts with
[2022.12.10-11.57.36:345]
this format.
Right now ,
logdate : raw log's timestamp
#timestamp : the time that log send to opensearch
I want to match logdate and #timestamp.
How can I modify the filter.date.match part to make the results of the logdate and #timestamp filters the same?
If you have multiple times you can have more than one filter.date.match, you can do this:
filter{
date {
match => ["logdate", "yyyy.MM.dd-HH.mm.ss:SSS"]
timezone => "UTC"
target=>"logdate"
}
date {
match => ["#timestamp", "yyyy.MM.dd-HH.mm.ss:SSS"]
timezone => "UTC"
target=>"#timestamp"
}
}
If your time field has multiple formats, you can do this:
date {
match => [ "logdate", "yyyy.MM.dd-HH.mm.ss:SSS", "third_format", "ISO8601" ]
target=> "#timestamp"
}

I'm trying to convert the syslog date format to a date timestamp that kibana recognizes, since it always appears as a string once the log is processed to elastic search.
This is what I've tried so far
input {
file {
path => "C:/Elasitcity/File Destination/logs2/*.*"
start_position => "beginning"
sincedb_path => "NUL"
}
}
filter {
grok {
match => {"message" =>"%{SYSLOGTIMESTAMP:logstamp}.*POST for %{URIPATH:ServiceURI}"}
}
date {
match => [ "logstamp", "MMM dd HH:mm:ss" ]
}
}
output {
elasticsearch {
hosts => "localhost"
index => "nextgen2"
document_type => "netboading"
}
stdout {}
}
I'm trying to extract the date from this log below
Jun 12 04:27:35 1560306455 INCOMING: information 22.244.42.41 Jun 12 04:27:22 DPPRD01 [host_services][0x80e0013a][mpgw][info] source-https(IMS_SSL_29982): trans(2797190703)[12.6.1.16]: Received HTTP/1.1 POST for /services/NHgetInternetLimitsV1 from 10.6.17.166
I'm simply trying to get elastic search to acknowledge logstamp as a timestamp that kibana can use for dashboarding purposes.
I think you need to set your target like this:
date{
match => ["logstamp", "MMM dd HH:mm:ss", "ISO8601"]
timezone => "Europe/Berlin"
target => "#timestamp"
}
I am having an issue with setting a timestamp from a JSON parse.
I have this string:
[{"orderNumber":"423523-4325-3212-4235-463a72e76fe8","externalOrderNumber":"reactivate_22d6ff0d8f55eb821be14df9d35505a6","operation":{"name":"CAPTURE","amount":134,"status":"SUCCESS","createdAt":"2015-05-11T09:14:30.969Z","updatedAt":{}}}]
I parse it as a json using this Logstash filter:
grok {
match => { "message" => "\[%{GREEDYDATA:firstjson}\]%{SPACE} \[%{GREEDYDATA:secondjson}\}]}]"}
}
json{
source => "firstjson"
}
date {
match => [ "operation.createdAt", "ISO8601"]
}
mutate {
remove_field => [ "firstjson", "secondjson" ]
}
}
This creates a document inside the ElasticSearch. I have a field named operation.createdAt which is properly recognised as a date field. But for some reason, this line:
date {
match => [ "operation.createdAt", "ISO8601"]
}
is not setting #timestamp field. Current #timestamp field is set at the moment of document insertion. What am I doing wrong?
Thanks to nice people at ES Logstash Community, I have found the answer.
Instead of:
date {
match => [ "operation.createdAt", "ISO8601"]
}
I use this:
date {
match => [ "[operation][createdAt]", "ISO8601"]
}
and that properly extracts and parses the JSON time object.
I have ELK running for log analysis. I have everything working. There are just a few tweaks I would like to make. To all the ES/ELK Gods in stackoverflow, I'd appreciate any help on this. I'd gladly buy you a cup of coffee! :D
Example:
URL: /origina-www.domain.com/this/is/a/path?page=2
First I would like to get the entire path as seen above.
Second, I would like to get just the path before the parameter: /origina-www.domain.com/this/is/a/path
Third, I would like to get just the parameter: ?page=2
Fourth, I would like to make the timestamp on the logfile be the main time stamp on kibana. Currently, the timestamp kibana is showing is the date and time the ES was processed.
This is what a sample entry looks like:
2016-10-19 23:57:32 192.168.0.1 GET /origin-www.example.com/url 200 1144 0 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" "-" "-"
Here's my config:
if [type] == "syslog" {
grok {
match => ["message", "%{IP:client}\s+%{WORD:method}\s+%{URIPATHPARAM:request}\s+%{NUMBER:bytes}\s+%{NUMBER:duration}\s+%{USER-AGENT}\s+%{QS:referrer}\s+%{QS:agent}%{GREEDYDATA}"]
}
date {
match => [ "timestamp", "MMM dd, yyyy HH:mm:ss a" ]
locale => "en"
}
}
ES Version: 5.0.1
Logstash Version: 5.0
Kibana: 5.0
UPDATE: I was actually able to solve it by using:
grok {
match => ["message", "%{IP:client}\s+%{WORD:method}\s+%{URIPATHPARAM:request}\s+%{NUMBER:bytes}\s+%{NUMBER:duration}\s+%{USER-AGENT}\s+%{QS:referrer}\s+%{QS:agent}%{GREEDYDATA}"]
}
grok {
match => [ "request", "%{GREEDYDATA:uri_path}\?%{GREEDYDATA:uri_query}" ]
}
kv {
source => "uri_query"
field_split => "&"
target => "query"
}
In order to use the actual timestamp of your log entry rather than the indexed time, you could use the date and mutate plugins as such to override the existing timestamp value. You could have your logstash filter look, something like this:
//filtering your log file
grok {
patterns_dir => ["/pathto/patterns"] <--- you could have a pattern file with such expression LOGTIMESTAMP %{YEAR}%{MONTHNUM}%{MONTHDAY} %{TIME} if you have to change the timestamp format.
match => { "message" => "^%{LOGTIMESTAMP:logtimestamp}%{GREEDYDATA}" }
}
//overriding the existing timestamp with the new field logtimestamp
mutate {
add_field => { "timestamp" => "%{logtimestamp}" }
remove_field => ["logtimestamp"]
}
//inserting the timestamp as UTC
date {
match => [ "timestamp" , "ISO8601" , "yyyyMMdd HH:mm:ss.SSS" ]
target => "timestamp"
locale => "en"
timezone => "UTC"
}
You could follow up Question for more as well. Hope it helps.
grok {
match => ["message", "%{IP:client}\s+%{WORD:method}\s+%{URIPATHPARAM:request}\s+%{NUMBER:bytes}\s+%{NUMBER:duration}\s+%{USER-AGENT}\s+%{QS:referrer}\s+%{QS:agent}%{GREEDYDATA}"]
}
grok {
match => [ "request", "%{GREEDYDATA:uri_path}\?%{GREEDYDATA:uri_query}" ]
}
kv {
source => "uri_query"
field_split => "&"
target => "query"
}
I'm trying to find out the results from a search query (ie: searching results for the given date range) of a particular index. So that I could get the results in a daily basis.
This is the query : http://localhost:9200/dialog_test/_search?q=timestamp:[2016-08-03T00:00:00.128%20TO%202016-08-03T23:59:59.128]
In the above, timestamp is a field which i added using my logstash.conf in order to get the actual log time. When i tried querying this, surprisingly i got a number of hits (total hits: 24) which should've been 0 since I didn't have any log records from the date of (2016-08-03) . It actually displays the count for the next day (ie: (2016-08-04), which has 24 records in the log file. I'm sure something has gone wrong with the timezone.
My timezone is GMT+5:30.
Here is my filtering part of logstash conf:
filter {
grok {
patterns_dir => ["D:/ELK Stack/logstash/logstash-2.3.4/bin/patterns"]
match => { "message" => "^%{LOGTIMESTAMP:logtimestamp}%{GREEDYDATA}" }
}
mutate {
add_field => { "timestamp" => "%{logtimestamp}" }
remove_field => ["logtimestamp"]
}
date {
match => [ "timestamp" , "ISO8601" , "yyyyMMdd HH:mm:ss.SSS" ]
target => "timestamp"
locale => "en"
}}
EDIT:
This is a snap of the first 24 records which has the date of (2016-08-04) from the log file:
And this is a snap of the JSON response I got when I searched for the date of 2016-08-03:
Where am i going wrong? Any help could be appreciated.
In your date filter you need to add a timezone
date {
match => [ "timestamp" , "ISO8601" , "yyyyMMdd HH:mm:ss.SSS" ]
target => "timestamp"
locale => "en"
timezone => "Asia/Calcutta" <--- add this
}
my system audit log contains the date format like created_at":1422765535789, so, the elastic search output also displays the date as same style. however, I would like convert and print this 1422765535789 to unix style date format.
I've used this format in syslog file (as suggested by another question thread) . but I am not getting the above value to unix style Date format
date {
match => ["created_at", "UNIX_MS"]
}
Hi, I've updated the code in the syslog , however, I am getting the created_at still output to elastic search page on same format like 1422765535789 , please find the modified code
input {
stdin {
}
}
filter {
grok {
match => [ "message", "%{NUMBER:created_at}"
]
}
if [message] =~ /^created_at/ {
date {
match => [ "created_at" , "UNIX_MS" ]
}
ruby {
code => "
event['created_at'] = Time.at(event['created_at']/1000);
"
}
}
}
output {
elasticsearch { host => localhost }
stdout { codec => rubydebug }
}
The date filter is used to update the #timestamp field value.
input {
stdin {
}
}
filter {
grok {
match => [ "message", "%{NUMBER:created_at:int}"
]
}
if "_grokparsefailure" not in [tags]
{
date {
match => [ "created_at" , "UNIX_MS" ]
}
ruby {
code => "
event['created_at'] = Time.at(event['created_at']/1000);
"
}
}
}
output
{
stdout {
codec => rubydebug
}
}
Here is my config. When I input 1422765535789, it can parse the value and update the #timestamp field value.
The output is
{
"message" => "1422765535789",
"#version" => "1",
"#timestamp" => "2015-02-01T04:38:55.789Z",
"host" => "ABC",
"created_at" => "2015-02-01T12:38:55.000+08:00"
}
You can found the value of #timestamp is same with created_at.
And, the ruby filter is used to convert the created_at to UTC format.
FYI.
