[flexibleengine_ces_alarmrule] - unable to monitor multiple RDS nodes inside the same alarm

[alpersid]

Hello guys,

I'm trying to create an Alarm which will monitor the RDS instance ( MYSQL HA ).

Each Mysql RDS instance have 2 nodes ( master / slave ).

While creating from the GUI everything is working properly. However, I think there's a limitation using terraform or the API.

If there is only one monitoring object ( flexibleengine_rds_instance_v3.RDS_instance.nodes[0].id in my example), everything is working properly. However, if I put two dimensions blocks, it will create a "dummy" monitoring object which will not link to an existing one.

    namespace = each.value.namespace
    metric_name = each.value.metric_name

Actual Behavior

There's no way to have multiple RDS nodes inside the same alarm

Steps to Reproduce

1. terraform apply

@alpersid According to the API Response between with 2 monitored objects created from Terraform and with 1 monitored object created from Terraform, I find that the value of "metric_name" are different, can you use rds001_cpu_util and try again?

You can also open a service ticket to OCB for technical support.

@alpersid I'm going to close this issue because there are no updates for 20 days. If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further.
