## The URL-prefix for Hookshot generic webhooks has changed
Until now, generic Hookshot webhook URLs looked like this: `https://matrix.DOMAIN/hookshot/webhooks/:hookId`.
Until now, generic Hookshot webhook URLs looked like this: `https://matrix.example.com/hookshot/webhooks/:hookId`.
The `/hookshot/webhooks` common prefix gets stripped by Traefik automatically, so Hookshot only sees the part that comes after (`/:hookId`).

That is, for people who have `matrix_static_files_file_index_html_enabled: false` in their `vars.yml` configuration, the playbook has a new default behavior. Since the playbook is not managing the `index.html` file, it will default to a more sensible way of handling the base domain - redirecting `https://DOMAIN/` to `https://matrix.DOMAIN/`, instead of serving a 404 page.

If you are managing your static website by yourself (by dropping files into `/matrix/static-files/public` somehow), then you probably don't wish for such redirection to happen. You can disable it by adding `matrix_static_files_container_labels_base_domain_root_path_redirection_enabled: false` to your `vars.yml` configuration file.

Doing so, services can contact Traefik on this entrypoint's dedicated port (the URL defaults to `http://matrix-traefik:8008`) and reach the homeserver Client-Server API as they expect. Internally, Traefik takes care of the routing to the correct service.
We've also considered keeping it simple and having services talk to the homeserver over the public internet (e.g. `https://matrix.DOMAIN`) thus reusing all existing Traefik routing labels. In this scenario, performance was incredibly poor (e.g. 70 rps, instead of 1400 rps) due to TLS and networking overhead. The need for fast internal communication (via the new internal non-TLS-enabled Traefik entrypoint) is definitely there. In our benchmarks, Traefik even proved more efficient than nginx at doing this: ~1200 rps for Traefik compared to ~900 rps for nginx (out of ~1400 rps when talking to the Synapse homeserver directly).

**TLDR**: we've made extensive **changes to metrics exposure/collection, which concern people using an external Prometheus server**. If you don't know what that is, you don't need to read below.
**Why do major changes to metrics**? Because various services were exposing metrics in different, hacky, ways. Synapse was exposing metrics at `/_synapse/metrics` and `/_synapse-worker-.../metrics` on the `matrix.DOMAIN`. The Hookshot role was **repurposing** the Granana web UI domain (`stats.DOMAIN`) for exposing its metrics on `stats.DOMAIN/hookshot/metrics`, while protecting these routes using Basic Authentication **normally used for Synapse** (`/_synapse/metrics`). Node-exporter and Postgres-exporter roles were advising for more `stats.DOMAIN` usage in manual ways. Each role was doing things differently and mixing variables from other roles. Each metrics endpoint was ending up in a different place, protected by who knows what Basic Authentication credentials (if protected at all).

Each metrics endpoint was ending up in a different place, protected by who knows what Basic Authentication credentials (if protected at all).
**The solution**: a completely revamped way to expose metrics to an external Prometheus server. We are **introducing new `https://matrix.DOMAIN/metrics/*` endpoints**, where various services *can* expose their metrics, for collection by external Prometheus servers. To enable the `/metrics/*` endpoints, use `matrix_nginx_proxy_proxy_matrix_metrics_enabled: true`. There's also a way to protect access using [Basic Authentication](https://en.wikipedia.org/wiki/Basic_access_authentication). See the `matrix-nginx-proxy` role or our [Collecting metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-metrics-to-an-external-prometheus-server) documentation for additional variables around `matrix_nginx_proxy_proxy_matrix_metrics_enabled`.

**If you are using the [Hookshot bridge](docs/configuring-playbook-bridge-hookshot.md)**, you may find that:
1. **Metrics may not be enabled by default anymore**:
- If Prometheus is enabled (`prometheus_enabled: true`), then Hookshot metrics will be enabled automatically (`matrix_hookshot_metrics_enabled: true`). These metrics will be collected from the local (in-container) Prometheus over the container network.
- **If Prometheus is not enabled** (you are either not using Prometheus or are using an external one), **Hookshot metrics will not be enabled by default anymore**. Feel free to enable them by setting `matrix_hookshot_metrics_enabled: true`. Also, see below.
2. When metrics are meant to be **consumed by an external Prometheus server**, `matrix_hookshot_metrics_proxying_enabled` needs to be set to `true`, so that metrics would be exposed (proxied) "publicly" on `https://matrix.DOMAIN/metrics/hookshot`. To make use of this, you'll also need to enable the new `https://matrix.DOMAIN/metrics/*` endpoints mentioned above, using `matrix_nginx_proxy_proxy_matrix_metrics_enabled`. Learn more in our [Collecting metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-metrics-to-an-external-prometheus-server) documentation.
3. **We've changed the URL we're exposing Hookshot metrics at** for external Prometheus servers. Until now, you were advised to consume Hookshot metrics from `https://stats.DOMAIN/hookshot/metrics` (working in conjunction with `matrix_nginx_proxy_proxy_synapse_metrics`). From now on, **this no longer works**. As described above, you need to start consuming metrics from `https://matrix.DOMAIN/metrics/hookshot`.

When metrics are meant to be **consumed by an external Prometheus server**, `matrix_hookshot_metrics_proxying_enabled` needs to be set to `true`, so that metrics would be exposed (proxied) "publicly" on `https://matrix.example.com/metrics/hookshot`.

**If you're using node-exporter** (`matrix_prometheus_node_exporter_enabled: true`) and would like to collect its metrics from an external Prometheus server, see `matrix_prometheus_node_exporter_metrics_proxying_enabled` described in our [Collecting metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-metrics-to-an-external-prometheus-server) documentation.

**If you're using [postgres-exporter](docs/configuring-playbook-prometheus-postgres.md)** (`prometheus_postgres_exporter_enabled: true`) and would like to collect its metrics from an external Prometheus server, see `matrix_prometheus_services_proxy_connect_prometheus_postgres_exporter_metrics_proxying_enabled` described in our [Collecting metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-metrics-to-an-external-prometheus-server) documentation.

You will be able to collect its metrics from `https://matrix.example.com/metrics/postgres-exporter`.
**If you're using Synapse** and would like to collect its metrics from an external Prometheus server, you may find that:
1. Exposing metrics is now done using `matrix_synapse_metrics_proxying_enabled`, not `matrix_nginx_proxy_proxy_synapse_metrics: true`. You may still need to enable metrics using `matrix_synapse_metrics_enabled: true` before exposing them.
2. Protecting metrics endpoints using [Basic Authentication](https://en.wikipedia.org/wiki/Basic_access_authentication) is now done in another way. See our [Collecting metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-metrics-to-an-external-prometheus-server) documentation
3. If Synapse metrics are exposed, they will be made available at `https://matrix.DOMAIN/metrics/synapse/main-process` or `https://matrix.DOMAIN/metrics/synapse/worker/TYPE-ID` (when workers are enabled), not at `https://matrix.DOMAIN/_synapse/metrics` and `https://matrix.DOMAIN/_synapse-worker-.../metrics`
3. If Synapse metrics are exposed, they will be made available at `https://matrix.example.com/metrics/synapse/main-process` or `https://matrix.example.com/metrics/synapse/worker/TYPE-ID` (when workers are enabled), not at `https://matrix.example.com/_synapse/metrics` and `https://matrix.example.com/_synapse-worker-.../metrics`
4. The playbook still generates an `external_prometheus.yml.example` sample file for scraping Synapse from Prometheus as described in [Collecting Synapse worker metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-synapse-worker-metrics-to-an-external-prometheus-server), but it's now saved under `/matrix/synapse` (not `/matrix`).
**If you where already using a external Prometheus server** before this change, and you gave a hashed version of the password as a variable, the playbook will now take care of hashing the password for you. Thus, you need to provide the non-hashed version now.

To do so, you'd need to explicitly set `matrix_nginx_proxy_proxy_synapse_metrics: true`.
