Request for sending data via telemetry

The goal is to collect metrics about client-side package installations (rpm-ostree install) to understand how commonly customers and partners use this unsupported workflow.

This data is critical for evaluating the potential customer impact of deprecating or altering this functionality in future architectures, such as bootc-based systems. It will help us understand what percentage of machines have locally layered packages that are not official CoreOS extensions, preventing unexpected user impact during future upgrades or architectural shifts.

Metric name

• cluster:mcd_nodes_with_unsupported_packages:count represents the total number of nodes in the cluster that have one or more unsupported packages installed.
• cluster:mcd_total_unsupported_packages:sum represents the sum of all unsupported packages across all nodes in the cluster.

The cardinality is 2 time series per cluster.
