This Django package provide Models for syncing data fom a Icinga/Nagios instance.
This may useful if you want to make queries to you monitoring system without
directly connect to it for each lookup.
It is currently tested with Icinga 1.10.3.
The package consist of 2 main parts
### Django Models
This is the datastruructure. I directly correlates with the Nagios/Icinga Services,
Servicegroups, Hosts and Hostgroups.
### Management Command
The package provides a Management Command to sync the Data from the Nagios/Icinga Server.
You may also sync only parts of monitoring data e.g. only specific Hostgroups or Servicegroups
To install simply fetch it from pypi.
pip install django-nagios-cache
After that you have to add ```nagios_cache``` to your ```INSTALLED_APPS``` and
python manage.py migrate nagios_cache
This will add the 4 Models to your database.
django-nagios-cache reads 4 configuration variables from your settings.py:
NAGIOS_CACHE_URL = "https://monitoring.example.org/cgi-bin/icinga/status.cgi"
NAGIOS_CACHE_USER' = "nagios_user",
NAGIOS_CACHE_PASSWORD' = "password_4_nagios_123",
NAGIOS_CACHE_AUTOCLEAN = False
NAGIOS_CACHE_AUTOCLEAN_DAYS = 5
You MUST specify ```NAGIOS_CACHE_URLNAGIOS_CACHE_URL```, while the other 2 are optional.
If there are no authentication details, ```django-nagios-cache``` will fetch the
data without authentication.
If you set ```NAGIOS_CACHE_AUTOCLEAN = True``` every query will automatically
clean up the last ```NAGIOS_CACHE_AUTOCLEAN_DAYS``` unsynced entries.
At the first run you may want to execute
python manage.py nagios_sync
This will sync everything. Note this could take some time. On my machine 20000 checks, 1500 hosts, 200 hostgroups and 10 servicegroups this take about 4 minutes.
Later you may chose only to sync specific parts. Have a look at
./manage.py nagios_sync --help
--hostgroups [HOSTGROUPS [HOSTGROUPS ...]]
Only sync the given hostgroups
--servicegroups [SERVICEGROUPS [SERVICEGROUPS ...]]
Only sync the given servicegroups
--sync-hosts Sync hosts
--sync-services Sync services
--sync-hostgroups Sync hostgroups
--sync-servicegroups Sync servicegroups
--clean Cleanup database entries that are old than 1 day
You can add this script to a crontab or use the API for a celery task. Have a
look at ```nagios_cache/management/commands/nagios_sync```. There are the calls for
the commandline options above.
from django.utils import timezone
t = timezone.now()
