how to get the backend_status using qiskit?

Question

I was preparing for the exam and I was confused about how to get job and backend status using qiskit, do we use Job_monitor for both of them?

Answer 1

We use Job_monitor to get the status of a job (IBMQJob instance)

To get the status of an IBMQ backend, we use IBMQBackend.status() which returns a BackendStatus instance:

from qiskit import IBMQ

if IBMQ.active_account() is None:
    IBMQ.load_account()

provider = IBMQ.get_provider(hub = 'ibm-q')
backend = provider.get_backend('ibmq_quito')

print('Status:')
print('  Operational: ', backend.status().operational)
print('  Pending jobs:', backend.status().pending_jobs)
print('  Status message:', backend.status().status_msg)

Result of this code snippet should be some thing like:

Status:
  Operational:  True
  Pending jobs: 108
  Status message: active
