Define filter - to use second field as timestamp and add year

Elastic Stack Logstash
1

My logs entries look like that:

<<DEBUG>>  **[Mar 01 14:55:18]** [[ACTIVE] ExecuteThread: '5' for queue: 'weblogic.kernel.Default (self-tuning)'] [CM] [OMS] (BasicParameter.getEffectiveDate) Exit
<<DEBUG>>  [Mar 01 14:55:18] [[ACTIVE] ExecuteThread: '5' for queue: 'weblogic.kernel.Default (self-tuning)'] [CM] [OMS] (BasicParameter.getExpirationDate) Enter

I need to use the date as timestamp.

Following the code from my logstash.conf file:

            multiline {
                       patterns_dir => "/users/mpswrk1/LogStash/impls/patterns/patterns"
                       pattern => "^\<\<%{LOGLEVEL}\>\> "
                       negate => true
                       what => "previous"
            }
            grok {
                  match => { "message" => "\<\<%{LOGLEVEL:severity}\>\>  \[%{PARTTIMESTAMP:timestamp}\] \[\[%{DATA:status}\] %{DATA:execute_thread}\] \[%{WORD:source_app}\] \(%{JAVACLASS:method}\) %{DATA:exception_method_description}\: \(%{DATA:error_code}\) %{DATA:error_description}%{JAVASTACKTRACEPART:java_class_stack}" }
                  patterns_dir => "/users/mpswrk1/LogStash/impls/patterns/patterns"
            }
            date {
                  match => [ "timestamp" , "MMM dd, yyyy hh:mm:ss aa" ]
            }

*parttimestamp is a private
PARTTIMESTAMP %{MONTH} %{MONTHDAY} %{TIME

What's the question, exactly? Logstash will guess which year a log is from so you might not have to do anything.

It doesn't work. I am getting in the timestamp the current date, of inserting into the elasticsearch.

Maybe the date { match {......} } line is wrong?

4

Yes, you have to remove "yyyy" since there's no year in your timestamp. If the date filter fails it'll log an error message that usually points to where the problem is.

Will check and update. Thanks!

still not working, and I don't understand the reason.

This is how I defined it in the conf file:

            grok {
                  match => { "message" => "\<\<%{LOGLEVEL:severity}\>\>  \[%{PARTTIMESTAMP:timestamp}\] \[\[%{DATA}\] %{DATA}\] \[%{DATA:application}\] \[%{DATA}\] \(%{JAVACLASS}\) %{CISCO_REASON}.%{JAVACLASS}: \(%{DATA:error_code}\)" }
                  patterns_dir => "/etc/logstash/patterns"
            }
            date {
                  match => ["timestamp" , "MMM dd HH:mm:ss"]
                  #add_field => { "Status" => "Matched"}
                  #remove_field => ["timestamp"]
            }

Working
