Issue/Introduction
Installing VIP Authentication Hub, the installation stops and report the error:
2m33s Warning FailedComputeMetricsReplicas invalid metrics (1 invalid out of 1), first error is: failed to get cpu resource metric value: failed to get cpu utilization: unable to get metrics for resource cpu: no metrics returned from resource metrics API
Resolution
From the log line, the software complains that there's not enough CPU allocated to the Virtual Machine (VM).
As per documentation, there are some requirements. The numbers given are for the very basic demo mode (1):
| Parameter | Minimum Cluster Requirements | |-----------+-----------------------------------------------------------------------------| | CPU | 14 cores available in the cluster (7 cores in case enclave services are not | | | deployed). | | RAM | 44 GB available in the cluster. (28 GB in case enclave services are not | | | deployed). |
Add the following options when installing VIP Authentication Hub to ensure the installation limits to the basic requirement above:
--set ssp.deployment.size="demo" \ --set hazelcast-enterprise.cluster.memberCount=2"
The demo sizing is the minimum that should be set for VIP Authentication Hub to be installed.
For greater size of environment, refer to the documentation chapter "Deployment Sizing Considerations" (2).
