Graylog is a log management tool


Send a test message to check an input

The next line will send a test message to the TCP 12201 port of the graylog server, if you use UDP, add the -u flag to the nc command.

echo -e '{"version": "1.1","host":"","short_message":"Short message","full_message":"Backtrace here\n\nmore stuff","level":1,"_user_id":9001,"_some_info":"foo","_some_env_var":"bar"}\0' | nc -w 1 my.graylog.server 12201

To see if it arrives, you can check the Input you're trying to access, or at a lower level, you can ngrep with:

ngrep -d any port 12201

Or if you're using UDP:

ngrep -d any '' udp port 12201
