Get monitors [NEW in this forked version]

from mackerel.clienthde import Client

# Alternatively, you can set MACKEREL_APIKEY as environment variable
# And simply call "client = Client()"
client = Client(mackerel_api_key='<Put your API key')

# Specify list of ids to search, return a dict with id as key

Create monitor [NEW in this forked version]

from mackerel.clienthde import Client

# Alternatively, you can set MACKEREL_APIKEY as environment variable
# And simply call "client = Client()"
client = Client(mackerel_api_key='<Put your API key')
# Create monitor as specified in https://mackerel.io/api-docs/entry/monitors#create

    'metric': 'ConsumedReadCapacityUnits.table-name',
    'operator': '>',
    'warning': 700,
    'critical': 900
}
# Post params to Mackerel
# result['id'] will give Monitor id if create operation succeeded
result = client.create_monitor(params)

Update monitor [NEW in this forked version]

from mackerel.clienthde import Client

# Alternatively, you can set MACKEREL_APIKEY as environment variable
# And simply call "client = Client()"
client = Client(mackerel_api_key='<Put your API key')

monitor = monitors[monitor_id]
# In this example, we assume Monitor is class of MonitorService
monitor.warning = 800
monitor.critical = 1000
# Update params to Mackerel
result = client.update_monitor(
    monitor_id=monitor_id,
    monitor_params=monitor._to_post_params_dict()
