+
+## The matrix-prometheus-node-exporter role lives independently now
+
+**TLDR**: the `matrix-prometheus-node-exporter` role is now included from another repository. Some variables have been renamed. All functionality remains intact.
+
+The `matrix-prometheus-node-exporter` role (which configures [Prometheus node exporter](https://github.com/prometheus/node_exporter)) has been extracted from the playbook and now lives in its own repository at https://gitlab.com/etke.cc/roles/prometheus_node_exporter.
+
+It's still part of the playbook, but is now installed via `ansible-galaxy` (by running `just roles` / `make roles`). Some variables have been renamed (`matrix_prometheus_node_exporter_` -> `prometheus_node_exporter_`, etc.). The playbook will report all variables that you need to rename to get upgraded. All functionality remains intact.
+
+A new `matrix-prometheus-services-proxy-connect` role was added to the playbook to help integrate the new `prometheus_node_exporter` role with our own services (`matrix-nginx-proxy`)
+
+Other roles which aren't strictly related to Matrix are likely to follow this fate of moving to their own repositories. Extracting them out allows other Ansible playbooks to make use of these roles easily.

 Metrics and resulting graphs can contain a lot of information. This includes system specs but also usage patterns. This applies especially to small personal/family scale homeservers. Someone might be able to figure out when you wake up and go to sleep by looking at the graphs over time. Think about this before enabling anonymous access. And you should really not forget to change your Grafana password.
 
-Most of our docker containers run with limited system access, but the `prometheus-node-exporter` has access to the host network stack and (readonly) root filesystem. This is required to report on them. If you don't like that, you can set `matrix_prometheus_node_exporter_enabled: false` (which is actually the default). You will still get Synapse metrics with this container disabled. Both of the dashboards will always be enabled, so you can still look at historical data after disabling either source.
