Guidance for parsing log file

[Hamed_khosravi]

hi dears
I trying to pars some log files for WebSphere MQ and I'm not familiar with this logs, some lines of those logs different with others lines. for example :
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
2018-10-19 13:52:16,188 DEBUG -org.springframework.jms.core.JmsTemplate - Sending created message:

""""""""""""""""""""""""""""""""""""""""""""""""

and the other line may look like this :

"""""""""
2018-10-19 13:52:16,226 DEBUG -com.ada.msas.switchingImpl.SwitchingImpl - 1470490# SwitchingImpl.switching msg :

"""""""""""""""""""""""""""""""""""""""""""""""

how can I read those lines with logstash? the both of these line logged in one file.

Use a file input with a multiline codec

codec => multiline {
    pattern => "^%{TIMESTAMP_ISO8601} "
    negate => true
    what => "previous"
}
