(RHSA-2022:0587) Important: Service Telemetry Framework 1.3 (sg-core-container) security update

Service Telemetry Framework (STF) provides automated collection of measurements and data from remote clients, such as Red Hat OpenStack Platform or third-party nodes. STF then transmits the information to a centralized, receiving Red Hat OpenShift Container Platform (OCP) deployment for storage, retrieval, and monitoring.

Bug fixes:

• In some cases, Ceilometer metrics were not handled properly by sg-core. This resulted in some Ceilometer metrics not being stored in Prometheus. In this release, the processing of metrics has been enhanced to be more robust. While the sg-core has been enhanced to support larger messages from Ceilometer, an additional change is required to support passing the larger messages through the sg-bridge ring buffer. The changes required to fully support this functionality are being tracked in RHBZ#2053683. (BZ#2016460)
