Abstract

This document outlines the major features, enhancements, and known issues in this release of Service Telemetry Framework.

Making open source more inclusive

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Chapter 1. Introduction to Service Telemetry Framework release

3.1.1. Bug fixes

These bugs were fixed in this release of Service Telemetry Framework:

BZ#1901609

Previously, invalid storage templates resulted in the inability to set custom storageClass parameters for OpenShift Container Platform (OCP).

With this release, the ability to set custom storage parameters means that you can use Service Telemetry Framework (STF) with non-default storageClasses in OCP, such as OpenShift Container Storage (OCS).

3.1.2. Enhancements

This release of Service Telemetry Framework features the following enhancements:

BZ#1915944

Previously, a Service Telemetry Framework (STF) deployment enabled the AMQ Interconnect web interface by default, with no ability to turn it off. This increased the attack surface of an STF instance unnecessarily.

With this release, the AMQ Interconnect web interface is disabled by default. It can be enabled by an administrator by using a new configuration option.

BZ#1763711

When you use Service Telemetry Framework (STF) 1.2 with Red Hat OpenStack Platform (RHOSP) 16.1.3 or later, you can now monitor RHOSP services, such as Dashboard (horizon), Ceph Storage, Compute (nova), and ceilometer.

An example implementation of this is shown in the STF dashboards provided at https://github.com/infrawatch/dashboards/blob/master/deploy/rhos-cloud-dashboard.yaml in the Service Resource Usage panel.

BZ#1915948

Service Telemetry Framework 1.2 provides a new parameter to allow specification of the retention period for metrics storage in the metrics storage backend, Prometheus.

The default value remains at 24h. You can edit the value in the ServiceTelemetry manifest by using the backends.metrics.prometheus.storage.retention parameter.
