# Which Problems Are Solved
Zitadel did not provide easy correlation between errors, logs, traces
and metrics. The configuration for those instrumentations was also not
consistent, with some supporting different exporters then others.
Implementation and parsing of config was also spaghettified over
multiple packages, with awkward parsing and inconsistent naming of
options.
# How the Problems Are Solved
All telemetry is now merged under the name "instrumentation". Why?
1. We thought it was a good idea in the past to call the milestone
exporter `Telemtry` in the runtime config. Calling this `TelemetryV2`
looks weird.
2. Not everything is a meter and not everything is sent (tele...).
3. It's also
[defined](https://opentelemetry.io/docs/concepts/instrumentation/) as
such by the OTEL documentation.
## New features
- Adds structured, context based logging with trace-ID awareness
- Static log fields are added to the context, such as service and
request path
- Static log fields are injected in each logline emitted by the
application
- Structured logs can also be send to an otel exporter
- Structured logs can be printed to StdErr in text and JSON format
- Error sinks make sure every error is logged at the correct level:
- Warnings for client side errors (HTTP 400 range, Invalid request etc)
- Error for server side errors (Internal server errors)
- Metrics can now also be send to a OTEL collector. (previously they
could only be scraped from `/debug/metrics` with prometheus)
## Exporters
This change adds all the exporters supported by OTEL upstream and some
google specific exporters for our cloud deployment.
- StdOut / StdErr: all instrumentations
- OTEL gRPC / HTTP: all instrumentations
- Google: all instrumentations except logging
- Prometheus (pull-based): only metrics
The exception is profiling, which only supports the google exporting due
to lack of support by OTEL upstream.
## Configuration and structure
- All instrumentation is moved into the new `backend/v3/instrumentation`
package. It reuses configuration types, so both code and runtime
configuration are easier to understand.
- The `internal/telemetry` packages are removed.
- Instrumentation is started with a single function and a proper
shutdown function is now provided.
- Legacy configuration is still parsed from the runtime config, as long
as the new configuration is disabled. This allows backporting this
feature to v4 without breaking existing configurations.
# Additional Changes
- Devcontainer: set `$PATH` variable so installed go binaries can be run
individually, without NX.
- NX: install GCI tool to fix imports
# Additional Context
- Closes https://github.com/zitadel/zitadel/issues/8408
- Closes https://github.com/zitadel/zitadel/issues/6664
- Backport to v4
# Which Problems Are Solved
Comparing the v3 and v4 deployments we noticed an increase in memory
usage. A first analysis revealed that it might be related to the
(multiple) initialization of the `i18n.Translator`, partially related
# How the Problems Are Solved
Initialize the tranlator once (apart from the translator interceptor,
which uses context / request specific information) and pass it to all
necessary middleware.
# Additional Changes
Removed unnecessary error return parameter from the translator
initialization.
# Additional Context
- noticed internally
- backport to v4.x
# Which Problems Are Solved
The current v3alpha actions APIs don't exactly adhere to the [new
resources API
design](https://zitadel.com/docs/apis/v3#standard-resources).
# How the Problems Are Solved
- **Improved ID access**: The aggregate ID is added to the resource
details object, so accessing resource IDs and constructing proto
messages for resources is easier
- **Explicit Instances**: Optionally, the instance can be explicitly
given in each request
- **Pagination**: A default search limit and a max search limit are
added to the defaults.yaml. They apply to the new v3 APIs (currently
only actions). The search query defaults are changed to ascending by
creation date, because this makes the pagination results the most
deterministic. The creation date is also added to the object details.
The bug with updated creation dates is fixed for executions and targets.
- **Removed Sequences**: Removed Sequence from object details and
ProcessedSequence from search details
# Additional Changes
Object details IDs are checked in unit test only if an empty ID is
expected. Centralizing the details check also makes this internal object
more flexible for future evolutions.
# Additional Context
- Closes#8169
- Depends on https://github.com/zitadel/zitadel/pull/8225

# Which Problems Are Solved
ZITADEL currently selects the instance context based on a HTTP header
(see https://github.com/zitadel/zitadel/issues/8279#issue-2399959845 and
checks it against the list of instance domains. Let's call it instance
or API domain.
For any context based URL (e.g. OAuth, OIDC, SAML endpoints, links in
emails, ...) the requested domain (instance domain) will be used. Let's
call it the public domain.
In cases of proxied setups, all exposed domains (public domains) require
the domain to be managed as instance domain.
This can either be done using the "ExternalDomain" in the runtime config
or via system API, which requires a validation through CustomerPortal on
zitadel.cloud.
# How the Problems Are Solved
- Two new headers / header list are added:
- `InstanceHostHeaders`: an ordered list (first sent wins), which will
be used to match the instance.
(For backward compatibility: the `HTTP1HostHeader`, `HTTP2HostHeader`
and `forwarded`, `x-forwarded-for`, `x-forwarded-host` are checked
afterwards as well)
- `PublicHostHeaders`: an ordered list (first sent wins), which will be
used as public host / domain. This will be checked against a list of
trusted domains on the instance.
- The middleware intercepts all requests to the API and passes a
`DomainCtx` object with the hosts and protocol into the context
(previously only a computed `origin` was passed)
- HTTP / GRPC server do not longer try to match the headers to instances
themself, but use the passed `http.DomainContext` in their interceptors.
- The `RequestedHost` and `RequestedDomain` from authz.Instance are
removed in favor of the `http.DomainContext`
- When authenticating to or signing out from Console UI, the current
`http.DomainContext(ctx).Origin` (already checked by instance
interceptor for validity) is used to compute and dynamically add a
`redirect_uri` and `post_logout_redirect_uri`.
- Gateway passes all configured host headers (previously only did
`x-zitadel-*`)
- Admin API allows to manage trusted domain
