+6. Since the IBM Spectrum Scale version 5.1.1 any client querying the performance data from the IBM Spectrum Scale cluster needs the API key authentication. You need to create API key secret for the grafana-bridge application using key name 'scale_default'. 
+
+First check the secret 'ibm-spectrum-scale-perfmon-default-api-key' exists in your CNSA project

+```

+Copy the scale_default api key value from that secret, mounted as a file in core pods
