GeoNode's monitor must be enabled by default

[giohappy]

GeoNode monitoring must be enabled by default. It's a key element for the typical user, who wants to have reports on numners of users, data downloads, etc.

Enable and configure Monitoring
===============================

--> DJANGO_SETTINGS_MODULE=ihp.settings python manage.py collect_metrics -n -t xml -f
--> psql -c 'set timezone=UTC;'

1. settings
-------------------------------

CORS_ORIGIN_ALLOW_ALL = True

MONITORING_ENABLED = True
# add following lines to your local settings to enable monitoring
if MONITORING_ENABLED:
    INSTALLED_APPS += ('geonode.contrib.monitoring',)
    MIDDLEWARE_CLASSES += ('geonode.contrib.monitoring.middleware.MonitoringMiddleware',)
    MONITORING_CONFIG = None
    MONITORING_HOST_NAME = 'localhost'
    MONITORING_SERVICE_NAME = 'local-geonode'
    MONITORING_HOST_NAME = SITE_HOST_NAME

INSTALLED_APPS += ('geonode.contrib.ows_api',)

GEOIP_PATH = os.path.join(os.path.dirname(__file__), '..', 'GeoLiteCity.dat')

2. migrations
-------------------------------

DJANGO_SETTINGS_MODULE=<project_name>.settings python manage.py migrate monitoring
DJANGO_SETTINGS_MODULE=<project_name>.settings python manage.py updategeoip
DJANGO_SETTINGS_MODULE=<project_name>.settings python manage.py collect_metrics -n -t xml -f

3. configuration
-------------------------------

.. also update "Sites" from admin
.. also do not forget to enable notifications and configure them from user profile

please follow : http://docs.geonode.org/en/master/tutorials/admin/monitoring/#configuration

IMPORTANT:
 - Services Dates / Times are mandatory
 - Times must be in UTC

4. cront job
-------------------------------

sudo crontab -e

--> * * * * * supervisorctl  start geonode-monitoring

5. supervisor
-------------------------------

sudo apt install supervisor
sudo service supervisor restart
sudo update-rc.d supervisor enable

sudo vim /etc/supervisor/conf.d/geonode-monitoring.conf

As an app, it can be enabled by default, but there's also monitoring configuration part, which should be processed in ui by user.

Alternatively, there's autoconfigure code which should populate configuration based on settings (it's not very well tested though, just basic case), which should populate hosts and services. I can add MONITORING_AUTOCONFIGURE flag to settings, which will enable autoconf on deployment (when no host/service is defined), or just hardcode autoconfigure in geonode-generic.

I would be in favour of autonfiguring it.

Monitoring requires collector script to be run each minute. This can be done by cron task, or we can add it to uwsgi scheduler: http://uwsgi-docs.readthedocs.io/en/latest/Cron.html

[giohappy]

I would use a dedicated container for scheduled tasks (cron). It could be used both for monitoring and for scheduled backups. Don't you think?

ok. for further reference:

There was a misconfiguration causing no data were collected, i've added proper host name generation in settings for this.
