Team, While analyzing system log files in Linux, I came up with the below entry. How do we ignore such huge blocks in Logstash ?? I believe if we do not ignore this, it will be considered as a log and we will get incorrect data on the Kibana Dashboard. ```auto Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0 ND-INFO : Staring BCIAgent for Netdiagnostics ...

Join the lines of that message into a single event (use the multiline codec if you're using the file input). If you really want to drop such events you can use the drop filter wrapped in a conditional (see example in the drop plugin documentation). ---

> [@magnusbaeck](#): > > p filter wrapp Thanks for your response. I am currently using filebeat as my input and in that case I cannot use"multiline codec".. I have gone through the drop filter and just want to understand if the option can only be used for a single line or can we use it for a block ?? How can I use it for the above block of Junk Data that was posted earlier ?? Thank You ---

> I am currently using filebeat as my input and in that case I cannot use"multiline codec".. No, you should use Filebeat's multiline feature. > I have gone through the drop filter and just want to understand if the option can only be used for a single line or can we use it for a block ?? The drop filter acts on events. Events may contain one or more lines. ---
