salt-master is not receiving scheduled job event fired on salt-minion - salt-stack

Question

I would to like to ask you for a help. I use saltstack as a job scheduler for slaves (minions) and I would like to be able to see on master job events fired on minion.
My setup
Job is scheduled on salt-master using a pillar for given minion. Pillar is:
schedule_returner: mongo
schedule:
cmd:
function: cmd.run
args:
- date +%s >> /tmp/job_runs
minutes: 1
maxrunning: 1
Scheduled job is executed without any problem on minion. I can see returned data in mongodb and a new timestamp in my dummy file /tmp/job_runs. The configuration file on minion /etc/salt/minion.d/_schedule.conf is:
schedule:
__mine_interval: {enabled: true, function: mine.update, jid_include: true, maxrunning: 2, minutes: 60, return_job: false}
cmd:
args: [date +%s >> /tmp/job_runs]
function: cmd.run
maxrunning: 1
minutes: 1
This file was generated and I didn't modify it.
In minion log I can see:
[DEBUG ] SaltEvent PUB socket URI:
/var/run/salt/minion/minion_event_1fa42d8010_pub.ipc
[DEBUG ] SaltEvent PULL socket URI: /var/run/salt/minion/minion_event_1fa42d8010_pull.ipc
[DEBUG ] Initializing new IPCClient for path: /var/run/salt/minion/minion_event_1fa42d8010_pull.ipc
[DEBUG ] Sending event: tag = __schedule_return; data = {'fun_args': ['date +%s >> /tmp/job_runs'], 'jid': 'req', 'return':

'fun': 'cmd.run', 'id': 'vagrant.vm'}
[DEBUG ] Minion of "salt" is handling event tag '__schedule_return'
[DEBUG ] schedule.handle_func: Removing /var/cache/salt/minion/proc/20170222100305532940
[DEBUG ] LazyLoaded mongo.returner
Now I'm interested in listening to those events with tag __schedule_return.
On minion, I can run the following commands:
wget https://raw.github.com/saltstack/salt/develop/tests/eventlisten.py
sudo python eventlisten.py -n minion
The output of eventlisten.py is correct and I can see this event.
Now my question is: Is there any way to listen to this events on salt-master?
When I run almost the same commands on master:
wget https://raw.github.com/saltstack/salt/develop/tests/eventlisten.py
sudo python eventlisten.py
I'm not able to see those events fired on minion by my scheduled job.
My motivation to do this is that I'm running saltpad on my master and I would like to see my scheduled jobs in the recent jobs (websockets...).
Thank you for any help.

Listening for Events
The quickest way to watch the event bus is by calling the state.event runner on you salt-master:
salt-run state.event pretty=True
Firing Events
It's possible to fire an event to be sent up to the master from the minion using the event.send execution function:
salt-call event.send '__schedule_return' '{success: True, message: "It works!"}'
Reactor System
Salt's Reactor System gives the ability to trigger actions in response to an event. Reactor SLS files and event tags are associated in the master config file (by default /etc/salt/master or /etc/salt/master.d/reactor.conf).
In the master config section 'reactor:' you can specify a list of event tags to be matched. Each event tag can have a list of reactor SLS files to be run.
# Master config section "reactor"
reactor:
# Match tag "__schedule_return"
- '__schedule_return':
# Things to it matches the tag
- /srv/reactor/do_stuff.sls
See the documentation about the reactor system for more information about salt's reactor system.
