CLI tool to send and receive event data from Azure Event Hubs

Installation

Install this tool using pip:

pip install eventhubs

Usage

Receiving

For receiving data to an event hub, run:

eh eventdata receive

Sending

For sending a single event to an event hub, run:

eh eventdata send --text '{"message": "Hello Spank"}'

You can also send multiple events in a batch by using --text more than once:

eh eventdata send --text '{"message": "Hello Spank"}' --text '{"message": "Hello Spank (yes, again)"}'

For sending the lines in a text files as event, run:

eh eventdata send --lines-from-text-file multiline.txt

For sending the lines from stdin as event, run:

cat multiline.txt | eh eventdata send  

Configuration

You can set up the connection string and event hub name using the command line options:

eh eventdata receive --connection-string "Endpoint=.." --name "application-insights"

or the environment variables (or a mix of both):

export EVENTHUB_CONNECTION_STRING="Endpoint=sb://...="
export EVENTHUB_NAME="application-insights"

eh eventdata receive

eh eventdata receive --name "another-name"

Defaults to printing the message payload only, so it is easier to combine output with other tools, like jq:

$ eh eventdata receive | jq '.records[].tenantId' 
"1de2b364-21e1-4866-bb46-7804f17c417d"
"1de2b364-21e1-4866-bb46-7804f17c417d"
"1de2b364-21e1-4866-bb46-7804f17c417d"

But you can still turn on verbose and get more information about what's going on:

$ eh --verbose eventdata receive
Receiving events from mbranca
Received event from partition 0: {"records": [{....
