i am new to ELK. when i onboarded the below log file, it is going to "dead letter queue" in logstash because logstash couldn't able to process the events. I am not sure which type of plugin to use whether KV plugin or CSV plugin because first half of the events are normal and next half is in KV pair. Any help would be appreciated on how to write the filters.
Below is the sample log format.
