EXAMPLES
connect to localhost with default credentials and attach to a new temp
queue on the default exchange:
konsum
Connect to a host with TLS on a custom port, authenticating with SSL
client certificate. On every received message a callback is spawned.
The message will be ACKed when the callback exits successfully. First
500 bytes of the message body are printed to stderr. Header infos are
always printed to stderr:
konsum -o amqp.example.com -p 5673 -T -k amqp-key.pem -c amqp-crt.pem -y vhost -x exchange -X./callback.sh -a -c -a callback.config.sh -f 2 -r binding.key.# -l 500
Authenticate with user and pass. Attach to an existing queue. Generate a file
for every message:
konsum -o amqp.example.com -U user -P pass -q queue -t
Provide a custom CA cert for proving the server's identity via
enviroment:
$ env SYSTEM_CERTIFICATE_PATH=/etc/amqp/cacert.crt konsum -T -y vhost -x exchange -r#
You can have no bindings, or you can bind the queue to one or multiple exchanges + binding keys:
konsum -x x1 -r b1 -r b2 -x x2 -r b3
would bind the queue to exchange x1 with binding keys b1 and b2 and to exchange x2 with binding key b3.
Stop with ^C
agitprop - an AMQP publisher
agitprop [options]
If INPUTFILE is a file, the file is sent as a message and the program exits. If
INPUTFILE is a directory, the directory is watched via inotify ("hotfolder
mode") and every file, which is written and closed or moved in gets sent,
optionally only files which match one or several SUFFIXes. Optionally the file
name is written into a message header named HEADERNAME. Optionally
Content-Type and Content-Encoding headers are set via magic retrieved from file
contents.
Line-by-line mode sends one message per INPUTFILE line.
In "hotfolder mode" multiple directories can be watched and sent with distinct routingkeys.
OPTIONS
-r ROUTINGKEY --routingkey=ROUTINGKEY AMQP routing key

-S SUFFIX --suffix=SUFFIX Allowed file suffixes in hotfolder mode
-u[DIR] --remove[=DIR], --move[=DIR] Remove (or move to DIR) sent file in hotfolder mode
-d --dirscan Toggle initial directory scan in hotfolder mode (default: False)
-m --magic Toggle setting content-type and -encoding from file contents (default: False)

EXAMPLES
Send a message containing a file and put the filename into a fileName
message header:
agitprop -x amq.topic -r test -F fileName -f agitprop.hs
Watch two directories dir1 and dir2 and send files from dir1 with routingkey r1
and files from dir2 with routingkey r2, ignoring everything which is not *.txt
or *.zip, and set Content-Type and Content-Encoding automatically, and move all
sent files to subdir "done" (dir1/done and dir2/done, respectively):
agitprop -x amq.topic -F fileName -m -S .txt -S .zip -d -udone -r r1 -f dir1 -r r2 -f dir2

callbacks
konsum and arbeite can execute programs (-Xprogram) on reception of a message.
normal (old) mode
The callback is called with the following arguments:
-f filename
-n messagenumber
Optionally are added:
-r routingkey
-m contenttype
-e encoding
-i messageid
-t timestamp
-p priority
-R redelivered
Message headers are added through several -h options:
-h HEADER=VALUE
Any additional arguments provided by -a arg options are appended.
simple (new) mode
Wenn called with -i (--simple), the callback is called with only the filename
as argument. Any additional arguments provided by -a arg options are prepended.
ENVIRONMENT
The arguments provided in normal (old) mode are also available as environment
variables in both modes in the callback:
AMQP_FILE
AMQP_NUMBER
AMQP_ROUTINGKEY
AMQP_CONTENTTYPE
AMQP_ENCODING
AMQP_MSGID
AMQP_TIMESTAMP
AMQP_PRIORITY
AMQP_REDELIVERED
And the remaining message properties, too:
AMQP_SIZE
AMQP_TYPE
AMQP_USERID
AMQP_APPID
AMQP_CLUSTERID
AMQP_REPLYTO
AMQP_CORRID
AMQP_EXPIRATION
AMQP_DELIVERYMODE
Message headers, if any, are available as
AMQP_HEADER_KEY_0
AMQP_HEADER_VALUE_0
AMQP_HEADER_KEY_1
AMQP_HEADER_VALUE_1
etc.
