PROGRAM:

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
Simply print out the configuration and exit. No action taken.

--timeout TIMEOUT
Timeout in seconds for any blocking zmq operations.

--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
