Examples

Send messages to a queue named test:

echo Hello World | amqpcat --producer --uri=$CLOUDAMQP_URL --queue test

Consume from the queue named test:

amqpcat --consumer --uri=$CLOUDAMQP_URL --queue test

With a temporary queue, consume messages sent to the exchange amq.topic with the routing key 'hello.world':

amqpcat --consumer --uri=$CLOUDAMQP_URL --exchange amq.topic --routing-key hello.world

Consume from the queue named test, format the output as CSV and pipe to file:

amqpcat --consumer --uri=$CLOUDAMQP_URL --queue test --format "%e,%r,"%s"\n | tee messages.csv

Publish messages from syslog to the exchange 'syslog' topic with the hostname as routing key

tail -f /var/log/syslog | amqpcat --producer --uri=$CLOUDAMQP_URL --exchange syslog --routing-key $HOSTNAME

Consume, parse and extract data from json messages:

amqpcat --consumer --queue json | jq .property
