heat-api-cloudwatch is not listed in OpenStack service catalog
Environment
- Red Hat OpenStack Platform 8
- Red Hat OpenStack Platform 9
- Red Hat OpenStack Platform 10
- Red Hat OpenStack Platform 11
- Red Hat OpenStack Platform 12
Issue
- There is no heat-api-cloudwatch service in overcloud catalog;
- heat-api-cloudwatch service is running on controller nodes, but doesn't shown when listing the OpenStack catalog of services.
Resolution
Heat CloudWatch API, a AWS CloudWatch compatible API, was deprecated in Havana, Red Hat OpenStack Platform 4, and was finally removed in Queens, Red Hat OpenStack Platform 13.
After Havana and before Queens it was used for backward compatibility, its only goal was to provide the ability to push metrics to Ceilometer via Heat, using a presigned URL for CloudWatch API endpoint to certain pre-defined resources. As a result, there are not catalog records for heat-api-cloudwatch as it works with presigned URLs only.
The service is enabled for backward compatibility and it is not removed until Red Hat OpenStack 13, as it would be a customization against upstream and could break certain pre-defined heat resources.
Diagnostic Steps
Checking process listening port 8003, default for the AWS CloudWatch compatible API called heat-api-cloudwatch, it can be seen that several process are listening against that port.
[root@osp10-cc01p heat-admin]# lsof -i:8003

[root@osp10-cc01p heat-admin]#
Checking catalog list it can be seen that heat-api-cloudwatch doesn't show. In this example a catalog list of a common RHOSP10 installation is shown.
