   ## syslog server component
 	syslog server component of sidecar:
   - receives logs intended for [syslogd](https://linux.die.net/man/8/syslogd)
   - parses, validates and filters messages
-  - supported RFCs:
+  - converts messages to easy for further processing  _*partname=partvalue*_ format

 ### Producer
   - forwards(produces) messages to the broker

-  Sidecar infrastructure supplies syslog messages to producer in easy for processing  _*partname=partvalue*_ format.

+Interface of producer:
