log4stash is a log4net appender for easy logging of exceptions and messages to Elasticsearch indices.
You can configure few filters to analyze log events before they got sended to Elasticsearch similar to the filters on logstash.
The udp-forwarder is an open source library for Web APIs. It grabs http requests sent to the API, creates a rich log event in a JSON format and sends it to a remote log service, like Logstash, via UDP.
This is an optional meta-package which includes all "X4D Diagnostics TraceListener" implementations such as ConsoleTraceListener and UdpJsonTraceListener. You can reference individual trace listener packages if preferred, see package dependencies for a list.
