I enabled the NuoDB Insights free monitoring tool but it is not displaying the metrics from the host. Can you tell me why?
In this case you will look for an error message in the NuoCollection Agent Log (nuoca.log):
2019-01-06 19:03:30,013 NuoCA ERROR NuoAdminMon: Error code '500' when calling Admin Rest API: http://localhost:8888/api/2/domain/enforcer
2019-01-06 19:03:30,020 NuoCA ERROR NuoAdminMon: Error code '400' when calling Admin Rest API: http://localhost:8888/api/2/regions
The error message indicates that NuoCA was unable to reach the NuoDB Admin Rest API.
The solution for this is to run nuorestsvc which is always required to be running in order to allow NuoCA to collect the metrics data.
