Are there applications for sorting Nlog logs?

Question

.NET

Good evening, comrades, I encountered such a problem. You need to look through the logs of one application and look for errors that affect the system. Nlog is used for logging. The log files are quite large, but contain a lot of empty information. I think a lot of people have been in this situation.
Attention question. Is there some utility that allows you to conveniently group error messages? For example, show separately the number of fatal errors and group them according to levels (Info, Fatal, etc.)?
UPD: Are there any simple lightweight applications besides logstash?

Answer 1

logstash + kibana
