NAME

       fedmsg-logger - simply emit messages from the command-line to the fedmsg bus

SYNOPSIS

       fedmsg-logger   [--message   LOGGER_MESSAGE]  [--json-input]  [--topic  TOPIC]  [--modname
       MODNAME] [--cert-prefix CERT_PREFIX] [<common fedmsg options>]

       fedmsg-logger [-h|--help]

DESCRIPTION

       fedmsg-logger is a simple command-line utility to send messages to the fedmsg bus.  It  is
       an  ephemeral command, that doesn't bind a 0mq endpoint directly. It sends its messages to
       a fedmsg-relay(1) daemon that binds a persistent  endpoint  that  the  outside  world  can
       subscribe  to.   If the fedmsg-relay(1) service is not running at the address specified in
       the config, then fedmsg-logger will hang until that service becomes available.

       If --message is not specified, this command accepts messages from stdin.

OPTIONS

       -h, --help
              Print an help message and exit

       --message LOGGER_MESSAGE
              The message to send.

       --json-input
              Take each line of input as JSON.

       --topic TOPIC
              The topic to which the messages are sent. Defaults to log if unset.

       --modname MODNAME
              The module name to which the messages are sent. Defaults to logger if unset.

       --cert-prefix CERT_PREFIX
              Specify a different cert from /etc/pki/fedmsg

COMMON FEDMSG OPTIONS

       --io-threads IO_THREADS
              Number of io threads for 0mq to use

       --topic-prefix TOPIC_PREFIX
              Prefix for the topic of each message sent.

       --post-init-sleep POST_INIT_SLEEP
              Number of seconds to sleep after initializing.

       --config-filename CONFIG_FILENAME
              Config file to use.

       --print-config

       --timeout TIMEOUT

       --high-water-mark HIGH_WATER_MARK
              Limit on the number of messages in the queue before blocking.

       --linger ZMQ_LINGER
              Number of milliseconds to wait before timing out connections.

TOPIC CONSTRUCTION

       The full topic to which the messages are sent is constructed  from  the  topic_prefix  and
       environment  set  in the fedmsg configuration, and the --topic TOPIC and --modname MODNAME
       options this way:

              <topic_prefix>.<environment>.MODNAME.TOPIC

CAVEATS

       Note that when using --json-input, you must send valid JSON, including the use  of  double
       quotes as opposed to single quotes:

              {"a": 1} is valid JSON.

              {'a': 1} is invalid JSON.

EXAMPLES

       Send a message from standard input in JSON format:
              echo '{"a": 1}' | fedmsg-logger --json-input

       Send a message to the git.repo.update topic
              echo "Hai there." | fedmsg-logger --modname=git --topic=repo.update

       Send a simple message:
              fedmsg-logger --message="This is a message."

       Send a JSON-format message:
              fedmsg-logger --message='{"a": 1}' --json-input
