We are moving over to InfluxDB from ElasticSearch. We used logstash for log aggregation and I need to do something similar using InfluxDB. It looked like Telegraf and Logparser are a good replacement. Logstash provided a nice way of specifying the stack trace with codecs and multilines. I read that LogParser borrows quite a bit from Logstash and it too has an idea of multine, but it is not clear from the docs how to get it to work.
We are using log4net with the following layout (quite standard)
%date [%thread] %-5level %logger - %message%newline"
The %message field contains the stack trace too when using the Log.Error(msg, exception) overload.
