Get current time

(Android Games) #1

i would like to get the current timestamp from logstash, currently i'm using the following code to get the current time.

        input { 
stdin { codec => json }
# Supports "cron", "every", "at" and "in" schedules by rufus scheduler
schedule => { cron => "* * * * * UTC"}

}
filter {
ruby {
code => "event.set('updated_date', event.get('@timestamp'))"
}
}
output
{
elasticsearch
{
index => "test"

}
}

By current timestamp you mean the event processing time that is named @timestamp?

Your code does now the following:

{
"updated_date" => 2019-05-17T14:23:37.396Z,
"@version" => "1",
"message" => "helloworld",
"@timestamp" => 2019-05-17T14:23:37.396Z,
"host" => "testnode"
}

You can also do it:

filter {
ruby {
code => "event.set('updated_date', event.get('@timestamp'))"
}
mutate {
    add_field => { "mutate_time" => "%{@timestamp}" }
}
}

{
"@version" => "1",
"@timestamp" => 2019-05-17T14:25:32.110Z,
"mutate_time" => "2019-05-17T14:25:32.110Z",
"updated_date" => 2019-05-17T14:25:32.110Z,
"host" => "testnode",
"message" => "mutate_time"
}

One possible way would be to create a field at the start of the filter section like this (I do something similar)

  alter {
    add_field => {
      "[@metadata][now]" => "%{+YYYY.MM.dd.ss:SSS}"
    }
  }

Format it however you want. This can be added to any log message or used as the source to overwrite other fields...
