When we speak about stdin, stdout, and stderr, we’re implicitly talking about the default locations in an environment where our programs will int What makes stdin, stdout, and stderr "standard"? FAQ. So having done that we can now configure a stream in Graylog using our TCP input on port 1516 (the same we defined in our output section above) and add some rules on our message-fields so that we only see certain messages, e.

Rsyslog daemon can send log messages to be written in a file on the local filesystem (mostly in a file in /var/log/ directory) or to be piped to another local process or to be send to a local user console (to stdout), or send the message to a remote syslog server via TCP/UDP protocol, or even discard the message to /dev/null. Send one test message to Logstash to make sure everything works. Sends events to a generic HTTP or HTTPS endpoint. Graylog uses MongoDB to store metadata (stream, dashboards, roles, etc) and Elastic Search to store log entries. Apache log4net™ Config Examples.
