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 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 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"
}
So I have log messages of the format :
[INFO] <blah.blah> 2016-06-27 21:41:38,263 some text
[INFO] <blah.blah> 2016-06-28 18:41:38,262 some other text
Now I want to drop all logs that does not contain a specific string "xyz" and keep all the rest. I also want to index timestamp.
grokdebug is not helping much.
This is my attempt :
input {
file {
path => "/Users/username/Desktop/validateLogconf/logs/*"
start_position => "beginning"
}
}
filter {
grok {
match => {
"message" => '%{SYSLOG5424SD:loglevel} <%{JAVACLASS:job}> %{GREEDYDATA:content}'
}
}
date {
match => [ "Date", "YYYY-mm-dd HH:mm:ss" ]
locale => en
}
}
output {
stdout {
codec => plain {
charset => "ISO-8859-1"
}
}
elasticsearch {
hosts => "http://localhost:9201"
index => "hello"
}
}
I am new to grok so patterns above might not be making sense. Please help.
To drop the message that does not contain the string xyz:
if ([message] !~ "xyz") {
drop { }
}
Your grok pattern is not grabbing the date part of your logs.
Once you have a field from your grok pattern containing the date, you can invoque the date filter on this field.
So your grok filter should look like this:
grok {
match => {
"message" => '%{SYSLOG5424SD:loglevel} <%{JAVACLASS:job}> %{TIMESTAMP_ISO8601:Date} %{GREEDYDATA:content}'
}
}
I added a part to grab the date, which will be in the field Date. Then you can use the date filter:
date {
match => [ "Date", "YYYY-mm-dd HH:mm:ss,SSS" ]
locale => en
}
I added the ,SSS so that the format match the one from the Date field.
The parsed date will be stored in the #timestamp field, unless specified differently with the target parameter.
to check if your message contains a substring, you can do:
if [message] =~ "a" {
mutate {
add_field => { "hello" => "world" }
}
}
So in your case you can use the if to invoke the drop{} filter, or you can wrap your output plugin in it.
To parse a date and write it back to your timestamp field, you can use something like this:
date {
locale => "en"
match => ["timestamp", "ISO8601"]
timezone => "UTC"
target => "#timestamp"
add_field => { "debug" => "timestampMatched"}
}
This matches my timestamp in:
Source field: "timestamp" (see match)
Format is "ISO...", you can use a custom format that matches your timestamp
timezone - self explanatory
target - write it back into the event's "#timestamp" field
Add a debug field to check that it has been matched correctly
Hope that helps,

I am collecting and parsing Tomcat access-log messages using Logstash, and am storing the parsed messages in Elasticsearch.
I am using Kibana to display the log messges in Elasticsearch.
Currently I am using Elasticsearch 2.0.0, Logstash 2.0.0, and Kibana 4.2.1.
An access-log line looks something like the following:
02-08-2016 19:49:30.669 ip=11.22.333.444 status=200 tenant=908663983 user=0a4ac75477ed42cfb37dbc4e3f51b4d2 correlationId=RID-54082b02-4955-4ce9-866a-a92058297d81 request="GET /pwa/rest/908663983/rms/SampleDataDeployment HTTP/1.1" userType=Apache-HttpClient requestInfo=- duration=4 bytes=2548 thread=http-nio-8080-exec-5 service=rms itemType=SampleDataDeployment itemOperation=READ dataLayer=MongoDB incomingItemCnt=0 outgoingItemCnt=7
The time displayed in the log file (ex. 02-08-2016 19:49:30.669) is in local time (not UTC!)
Here is how I parse the message line:
filter {
grok {
match => { "message" => "%{DATESTAMP:logTimestamp}\s+" }
}
kv {}
mutate {
convert => { "duration" => "integer" }
convert => { "bytes" => "integer" }
convert => { "status" => "integer" }
convert => { "incomingItemCnt" => "integer" }
convert => { "outgoingItemCnt" => "integer" }
gsub => [ "message", "\r", "" ]
}
grok {
match => { "request" => [ "(?:%{WORD:method} %{NOTSPACE:request}(?: HTTP/%{NUMBER:httpVersion})?)" ] }
overwrite => [ "request" ]
}
}
I would like Logstash to convert the time read from the log message ('logTimestamp' field) into UTC before storing it in Elasticsearch.
Can someone assist me with that please?

I have added the date filter to my processing, but I had to add a timezone.
filter {
grok {
match => { "message" => "%{DATESTAMP:logTimestamp}\s+" }
}
date {
match => [ "logTimestamp" , "mm-dd-yyyy HH:mm:ss.SSS" ]
timezone => "Asia/Jerusalem"
target => "logTimestamp"
}
...
}
Is there a way to convert the date to UTC without supplying the local timezone, such that Logstash takes the timezone of the machine it is running on?
The motivation behind this question is I would like to use the same configuration file in all my deployments, in various timezones.
That's what the date{} filter is for - to parse a string field containing a date string replace the [#timestamp] field with that value in UTC.
This can also be done in an ingest processor as follows:
PUT _ingest/pipeline/chage_local_time_to_iso
{
"processors": [
{
"date" : {
"field" : "my_time",
"target_field": "my_time",
"formats" : ["dd/MM/yyyy HH:mm:ss"],
"timezone" : "Europe/Madrid"
}
}
]
}
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.
