Ruby - Ruby exception occurred: invalid date: "2019-04-18+06:23:35.919"

[Yoav_Ben_Moha]

I am trying to find a diff betweentwo dates.
I have wrote the following con file which use Ruby in order to caculate the date diff.
I recived : ruby - Ruby exception occurred: invalid date: "2019-04-18+06:23:35.919"

The conf file:
input {
file {
path => "/home/logstash/cdr_files/top10.csv"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}

filter {
        csv {
             separator => ","
           columns => [
                       "P9","P11","P21","P30"
                      ]
             }

        mutate { rename => { "P9" => "CALLING_NUMBER" } }
        mutate { rename => { "P11" => "CALLED_NUMBER" } }
        mutate { rename => { "P21" => "ING_SIGNAL_START_TIME" } }
        mutate { rename => { "P30" => "ING_CALL_ANSWER_TIME" } }

        date {
                match => [ "P21", "YYYY-MM-dd'+'HH:mm:ss.SSS" ]
                target => [ "ING_SIGNAL_START_TIME" ]
                remove_field => [ "P21" ]
              }


        date {
                match => [ "P30", "YYYY-MM-dd'+'HH:mm:ss.SSS" ]
                target => [ "ING_CALL_ANSWER_TIME" ]
                remove_field => [ "P30" ]
              }

ruby {
    init => "require 'time'"
    code => "
           starttime = Time.iso8601(event.get('ING_SIGNAL_START_TIME').to_s).to_f;
           endtime   = Time.iso8601(event.get('ING_ADDRESS_COMPLETE_TIME').to_s).to_f;
           event.set('time_diff', endtime - starttime);
            "
    add_tag => [ "ING_SST_MINUS_ING_ACT_CALCUALTED" ]
}

}

output {
        elasticsearch {
                        hosts => "localhost"
                        index => "top10"
                        document_type => "quick_log"
                      }
        stdout {}

Please advise whats wrong

Thanks Alot

You rename P21 and P30, then after that you try to parse those fields, which no longer exist. And the ruby filter references a non-existant ING_ADDRESS_COMPLETE_TIME field. How about

ruby {
    init => "require 'time'"
    code => "
       starttime = event.get('ING_SIGNAL_START_TIME').to_f;
       endtime   = event.get('ING_CALL_ANSWER_TIME').to_f;
       event.set('time_diff', endtime - starttime);
    "
    add_tag => [ "ING_SST_MINUS_ING_ACT_CALCUALTED" ]
}
