Hej Andy,

maybe you should separate the multiple messages you have by type into different 
log files to be able to have one pattern for every logfile.

I didn’t dig into NXLog that deep but again - someone in the NXLog community 
might help with that.

Subject:  Re: [graylog2] Re: Multiline message problems  

Hi Jan,

Thanks for the reply.

Before I share our million different log messages, can we discuss on the basis 
that a single regex won't capture our messages? We have multiline exceptions, 
multiline SQL statements, multiline various other types of messages. If NXLog 
multiline handling is stronger, is there anything I may have missed in terms of 
NXLog setup? Are there other alternatives (other than decorating our messages) 
I haven't considered, or obviously missed?

Thanks-

Hej Andy,

if you want help with the multiline detection of filebeat, we would need to 
have some information about your logfile. examples welcome.

with your question about nxlog the limit for one message is reached - you would 
need to configure this limit. But for this the NXLog Community might be the 
best place to ask.

regards
Jan

Hello all-

Windows app server into Graylog 2.1.0.

Like many, we have multiline log messages. There is presently no clearly 
defined syntax around these messages, no end delimiter.

I'm able to flow messages in using filebeat, but I can't capture multiline 
messages properly. I believe per a Graylog blog entry, I need a regex that 
matches the entire message. I don't think this is feasible with our 
widely-varied messages. We do have a well-defined phrase that starts every 
message, but I'm not sure how I would define the end of and capture the varied 
messages.

I've tried NXLog outputting to the system input of GELF TCP. I suspect NXLog 
has better multiline handling, but I can't flow messages reliably using NXLog - 
I get shut down repeatedly by the string size limit error in nxlog.log:

2017-02-16 17:13:06 INFO connecting to 10.100.15.196:12201
2017-02-16 17:13:06 INFO reconnecting in 1 seconds
2017-02-16 17:13:06 ERROR oversized string, limit is 1048576 bytes

Is there any way for me to correct this string size limit issue using NXLog CE?

Any other alternatives I'm not considering? Anything I'm doing obviously wrong, 
or missed?

Thanks in advance!
