Hi,
I just want to close this off by saying this is the code I am running:
host = get_json('%shosts/%s' % (satellite_url, hostname), username,
password)
display_json_results(host)
host_scp = get_json('%shosts/%d/smart_class_parameters' % (satellite_url,
host['id']), username, password)
for next_host_scp in host_scp['results']:
host_scp_overrides = get_json(
'%ssmart_class_parameters/%d/override_values' % (satellite_url,
next_host_scp['id']), username, password)
if len(host_scp_overrides['results']):
for next_override in host_scp_overrides['results']:
if next_override['match'] == 'fqdn=%s' % (host['name']):
print(' %s = %s' % (next_host_scp['parameter'], json.dumps(
next_override['value'], indent=6, sort_keys=True)))
elif output_verbosity == 'full':
print(' %s = %s' % (next_host_scp['parameter'], json.dumps(
next_host_scp['default_value'], indent=6, sort_keys=True)))
It needs a bit of tidying up, but does at least display the info I'm
interested in.
I actually wanted to group the variables by puppet class, but when I wrote
the code to find every smart class parameter associated with a puppet
class, and then every override associated with each parameter it was
tragically slow. Here's the code:
host = get_json('%shosts/%s' % (satellite_url, hostname), username,
password)
display_json_results(host)
print('Host is %s' % (host['name']))
parameters = get_json('%shosts/%s/parameters' % (satellite_url, host['id'
]), username, password)
for next_puppet_class in sorted(host['all_puppetclasses']):
print(' Puppet class [%s]' % (next_puppet_class['name']))
sc_params = get_json('%spuppetclasses/%d/smart_class_parameters' % (
satellite_url, next_puppet_class['id']), username, password)
if len(sc_params['results']):
sc_params_ids = set([next_sc_param['id'] for next_sc_param in
sc_params['results']])
for next_sc_param in sc_params_ids:
host_scp_overrides = get_json(
'%ssmart_class_parameters/%d/override_values' % (satellite_url,
next_sc_param), username, password)
for next_override in host_scp_overrides['results']:
if next_override['match'] == 'fqdn=%s' % (host['name']):
print('%s ' % (next_override['value']))
That takes 233 seconds, where as the first example code I gave takes 101
seconds (so neither is really acceptable, but I can't see a better way of
doing it).
Regards,
David
