An unofficial Python interface for obtaining metrics from Supermicro BMCs.
The following metrics are accessible:
Sensor: Temperature, Fan, Voltage, etc.
PMBus: Power Consumption, Fan, Temperature, etc.
Note: This library depends on the BMC web-interface being available.
Usage
Setup
# smbmc_example.py from smbmc import Client # initialise client with connection details c = Client(IPMI_SERVER, IPMI_USER, IPMI_PASS) # retrieve session token (usually lasts 30 minutes) # optional: the library maintains session tokens internally. c.login()
Sensor Metrics
# obtain sensor metrics
sensors = c.get_sensor_metrics()
for sensor in sensors:
print(sensor.__dict__)
# output (some removed for brevity)

PMBus Metrics
# obtain pmbus metrics
power_supplies = c.get_pmbus_metrics()
for psu in power_supplies:
print(psu.__dict__)
# output
{'id': 0, 'name': '', 'status': 'ff', 'type': '0', 'input_voltage': 0, 'input_current': 0.0, 'input_power': 0, 'output_voltage': 0.0, 'output_current': 0.0, 'output_power': 0, 'temp_1': 0, 'temp_2': 0, 'fan_1': 0, 'fan_2': 0}
{'id': 1, 'name': 'FAKE_PSU_SERIAL', 'status': '1', 'type': '1', 'input_voltage': 236, 'input_current': 0.359, 'input_power': 85, 'output_voltage': 12.1, 'output_current': 5.75, 'output_power': 69, 'temp_1': 38, 'temp_2': 53, 'fan_1': 2894, 'fan_2': 3810}
All Metrics
# obtain all metrics
metrics = c.get_metrics()
print(metrics)
# output
{'pmbus': [], 'sensor': []}
