Python interface to Nagios object and status files. Parses configuration files,
status.dat (status file) and represents information as collection of objects
with corresponding obj_type and attributes. Objects may be changed and saved.

nagdata package contains following modules:

nagdata      -- main module, interface to nagios object and status files,
                also provides class with simpler api
exceptions   -- exceptions used by nagdata
parser       -- parsers of nagios configuration and status files (parses list
                of lines)
cparser_fmt  -- parse file and keep format
cparser_fast -- just parse file and don't save format
nagfile      -- links together files and parsers, so we can parse files
collection   -- collection of Nagios objects
factory      -- factories to produce different Nagios objects
model        -- Nagios objects (hoststatus, servicestatus, service definition,
                etc)
fields       -- Types of Nagios object attributes
fmt          -- "Imaginary" format object helping to keep nagios file format and
                structure


Both cparser_fmt and cparser_fast are produced from the same cparser.c (and symlink
to it cparser2.c)

Some little examples:

# update status:

from nagdata import nagdata

n = nagdata.NagData()

n.update_status()



# retrieve some objects:

from nagdata.nagdata import *

n = NagData()

for o in n.filter(obj_type='servicestatus', host_name='c6509'):
    print o

hg = n.get('hostgroup', hostgroup_name='servers_corp')
print hg

sg = n.get('servicegroup', servicegroup_name='mailq_group')
print sg



# simpler api
from nagdata import nagdata

n = nagdata.NagDataSimpleApi()

# get host by address
h0 = n.get_host('172.16.1.1')
# get host by name
h1 = n.get_host('router1')

# statuses
print n.get_hoststatus('router1')
print n.get_servicestatus('PING', 'router1')

hg = n.get_hostgroup('servers_corp')

# change address
h0['address'] = 'router2'
# and save to file
n.save(h0)


# create and add object
from nagdata import nagdata

n = nagdata.NagDataSimpleApi()

#create and add config object
svc = n.new('service',
    service_description='PING',
    host_name='localhost')

# just create
svc = n.factory('service', service_description='PING')
svc['host_name'] = 'router1'
# add to config
n.config.add(svc)
