Modify_Config

Modify_config is a function in "monasca_setup/main.py" (link: https://github .com/openstack/monasca-agent/blob/master/monasca_setup/main.py). It compares existing and detected configurations for each check plugin and writes out the plugin configurations if there are changes.

Examples

There are two examples shown here using http_check: one is to add a new instance, another is to detect endpoint change on existing http_check instance.

Adding a new instance

old_config:

{'init_config': None,
 'instances': [{'built_by': 'HttpCheck',
                'name': 'logging',
                'url': 'http://127.0.0.1:9200',
                'use_keystone': False,
                'match_pattern': '.*VERSION.*',
                'collect_response_time': True,
                'timeout': '10',
                'dimensions': {'service': 'logging'}}]
}

monasca-setup arguments:

$ monasca-setup -d 'HttpCheck' -a 'url=http://192.168.10.6:8070
  match_pattern=.*OK.* name=monasca dimensions=service:monitoring'

input_config generated from monasca-setup:

{'http_check':
    {'instances': [{'built_by': 'HttpCheck',
                    'name': 'monasca',
                    'url': 'http://192.168.10.6:8070',
                    'use_keystone': False,
                    'match_pattern': '.*OK.*',
                    'collect_response_time': True,
                    'timeout': '10',
                    'dimensions': {'service': 'monitoring'}
                    }]
    'init_config': None
    }
}

output_config from modify_config:

{'init_config': None,
 'instances': [{'built_by': 'HttpCheck',
                'name': 'logging',
                'url': 'http://127.0.0.1:9200',
                'use_keystone': False,
                'match_pattern': '.*VERSION.*',
                'collect_response_time': True,
                'timeout': '10',
                'dimensions': {'service': 'logging'}},
               {'built_by': 'HttpCheck',
                'name': 'monasca',
                'url': 'http://192.168.10.6:8070',
                'use_keystone': False,
                'match_pattern': '.*OK.*',
                'collect_response_time': True,
                'timeout': '10',
                'dimensions': {'service': 'monitoring'}}]
}
