Java Exception not parsed well

[mooselau]

Hi,

I used "logagent" docker to ship my Java Project logs to sematext cloud, but it seems Java Exceptions(especially in multilines) could not be parsed well. I have tried to add some patterns myself but Exception logs still get multiple records in sematext cloud.

Below is my sample Exception trace:

2020-05-20 16:23:23.088 [scheduling-1] ERROR n.a.processor.agent.AQIUpdateAgent.doUpdating - Failed to update AQI

And one normal log sample:

2020-05-20 16:23:23.088 [scheduling-1] INFO  n.a.p.c.AQIHttpRequestHandler.proceedRequest - AQI server is querying

And my adding patterns in patterns.yml:

patterns:                                                                       
 - sourceName: !!js/regexp server.log
   match:                            
     - type: log_common              
       regex: !!js/regexp ^(([\d|\-|\:|.|\s]+)\s(\[.+\])\s([A-Z]+)\s(.+)-(.+))
       fields: [raw, ts, thread, severity, logger, message]                   
       dateFormat: yyyy-MM-dd HH:mm:ss.SSS                                    
                                                                               
 - sourceName: !!js/regexp server.log                                           
   blockStart: !!js/regexp ^(\S.+Exception:.+)         
   match:                                     
     - type: log_trace                        
       regex: !!js/regexp ^(\S.+Exception:.+\n\s+.*)
       fields: [stacktrace]

The trace look in sematext logs panel, and I wish to see one record in sematext logs but with the whole exception stack:

[otisg]

For your Java stack traces -- I assume that is not the complete stack trace. For example, I don't see the timestamp.

Hi @otisg , updated the stack traces, there is one ERROR log above the stack traces.
