Django MVC

Models

class monitor.models.Group(*args, **kwargs)

Group sites by type

class monitor.models.Outage(*args, **kwargs)

Records when an outage has taken place, including all the things that have gone down and the dates when it was resolved etc

class monitor.models.OutageSites(*args, **kwargs)

Records which sites are effected by the outage

class monitor.models.Site(*args, **kwargs)

Core information about a site

class monitor.models.SiteView(*args, **kwargs)

Records when it has been accessed and the code returned

This will get big very quickly, so there will need to be a database purge script written. This shouldn’t be done on save because the normal monitoring system should do no extra work.

Using a UUID rather than an auto-increment for the pk

Views

monitor.views.group_data(request, *args, **kwargs)

Returns a json object containing details for each site being monitored in this particular group

monitor.views.home(request)

Show monitoring results for all systems being monitored.

This doesn’t do any parsing, it just gets the latest information from the database. A seperate script does the db update work.

monitor.views.login_user(request)

Logs the user in

monitor.views.outage(request, *args, **kwargs)

Shows details of an outage, or the current outage if there is one

monitor.views.outages(request, *args, **kwargs)

Lists all outages recorded on the system. You can click on each one to view the details of it.

monitor.views.site_data(request, *args, **kwargs)

Returns details of the last 10 requests to view this particular site as a json object

Templatetags

readable_time

monitor.templatetags.readable_time.readable_time(value)

Pass it a time in seconds and it returns a human readable string showing the hours, minutes and seconds

number_suffix

monitor.templatetags.number_suffix.ordinal(value)

http://code.activestate.com/recipes/576888-format-a-number-as-an-ordinal/

Converts zero or a postive integer (or their string representations) to an ordinal value.

>>> for i in range(1,13):
...     ordinal(i)
...     
u'1st'
u'2nd'
u'3rd'
u'4th'
u'5th'
u'6th'
u'7th'
u'8th'
u'9th'
u'10th'
u'11th'
u'12th'

>>> for i in (100, '111', '112',1011):
...     ordinal(i)
...     
u'100th'
u'111th'
u'112th'
u'1011th'

paginator

monitor.templatetags.paginator.paginate(obj)

Takes an object obj and puts the pagination links on screen.

This is an inclusion tag rather than just calling the fragment because it is totally generic - it uses {{obj}} rather than the name of the variable.
