Monitorando a velocidade do ventilador da CPU no sistema Lenovo x3650 m5 (8871) no RHEL7

Question

Eu preciso monitorar um servidor x3650 m5 (8871) do sistema Lenovo. Infelizmente, lm_sensor mostra apenas a temperatura da CPU. Alguém tem um conselho, como eu poderia monitorar a velocidade do ventilador com uma ferramenta de linha de comando?

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
Probing for Super-I/O at 0x2e/0x2f
Trying family 'National Semiconductor/ITE'...               Yes
Found unknown chip with ID 0x3711
Probing for Super-I/O at 0x4e/0x4f
Trying family 'National Semiconductor/ITE'...               Yes
Found unknown chip with ID 0x7f00

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): 
Found 'IPMI BMC KCS' at 0xcc0...                            Success!
    (confidence 8, driver 'to-be-written')

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
Probing for 'National Semiconductor LM78' at 0x290...       No
Probing for 'National Semiconductor LM79' at 0x290...       No
Probing for 'Winbond W83781D' at 0x290...                   No
Probing for 'Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): 
Found unknown SMBus adapter 8086:8d22 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Answer 1

Seu sistema tem um BMC configurado corretamente com suporte a IPMI, portanto, você deve ser capaz de usar ipmitool localmente para extrair todas as informações de monitoramento suportadas pelo BMC:

yum install ipmitool
ipmitool sensor

(assumindo que o módulo ipmi_si esteja carregado, o que deve ser o caso do RHEL 7 em sua configuração). Os valores interessantes estão nas duas primeiras colunas (sensor e valor) e o quarto (indicador de saúde):
