A Django package to check that rq workers are running and notify admins if they are not

A Django package to check that rq workers are running and notify admins if they are not

Quickstart

Install Django RQ Pulse:

pip install django-rq-pulse

Add it to your INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'django_rq_pulse.apps.DjangoRqPulseConfig',
    ...
)

Define the SERVER_EMAIL and ADMINS Django settings because these settings will be used to send notification emails.

Define a dictionary in your Django settings for your Redis connection details like so:

REDIS_DB = {
    'host': 'Your Redis Hostname or IP goes here',
    'port': 'Your Redis port number goes here',
    'database': 'Your Redis database number goes here'
}

Usage

Check that rqworkers are running:

$ python manage.py rq_pulse_check

If the actual number of workers is less the expected number of workers or If there are items in the queue but the queue size is not changing notify admins by email.

The above command will run with default parameters where:

--expected-num-workers=2
--seconds-to-sleep=5
--num-retries=5
--queue-name="default"

You can override these values by passing any or all the parameters to the command like so:

$ python manage.py rq_pulse_check --expected-num-workers=3 --queue-name="high"

To get a list of the command parameters use the –help parameter:

$ python manage.py rq_pulse_check --help
