The `flush` method sets `start := b.clock.Now()` but later computes
duration with `time.Since(start)` instead of `b.clock.Since(start)` for
the `FlushDuration` metric and the debug log. Line 352 already uses
`b.clock.Since(start)` correctly — this makes the rest consistent.
Test output before fix:
```
flush complete count=100 elapsed=19166h12m30.265728663s reason=scheduled
```
After fix:
```
flush complete count=100 elapsed=0s reason=scheduled
```

This moves updating app status (used by Tasks) into the workspace agent
API over dRPC. This will allow us to update the status without having to
re-authenticate each time, like we would with an HTTP PATCH request.
Further PRs in this stack will pipe these requests thru from the CLI MCP
server to the agentsock and finally to this dRPC call to coderd.
Parent agents were re-using AuthInstanceID when spawning child agents.
This caused GetWorkspaceAgentByInstanceID to return the most recently
created sub agent instead of the parent when the parent tried to refetch
its own manifest.
Fix by not reusing AuthInstanceID for sub agents, and updating
GetWorkspaceAgentByInstanceID to filter them out entirely.
Since Go 1.22, the loop variable capture issue is resolved. Variables
declared by for loops are now per-iteration rather than per-loop, making
the 'v := v' pattern unnecessary.
Adds coderd_template_workspace_build_duration_seconds histogram that
tracks the full duration from workspace build creation to agent ready.
This captures the complete user-perceived build time including
provisioning and agent startup.
The metric is emitted when the agent reports ready/error/timeout via the
lifecycle API, ensuring each build is counted exactly once per replica.
Implements telemetry for boundary usage tracking across all Coder
replicas and reports them via telemetry.
Changes:
- Implement Tracker with Track(), FlushToDB(), and StartFlushLoop() methods
- Add telemetry integration via collectBoundaryUsageSummary()
- Use telemetry lock to ensure only one replica collects per period
The tracker accumulates unique workspaces, unique users, and request
counts (allowed/denied) in memory, then flushes to the database
periodically. During telemetry collection, stats are aggregated across
all replicas and reset for the next period.
Adds template_version_id to re-emitted boundary audit logs to allow
filtering and analysis by specific template versions iin addition to the
existing template_id field. Since boundary policies are defined in the
template, the template version is critical to figuring out which policy
was responsible for boundaries decision in a workspace.
Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
Boundary policies are currently defined at the template level, so
including the template ID in re-emitted logs by the control plane
allows policy creators to filter and observe boundary activity for
specific templates. This makes it easier to verify that policies are
working as expected and to debug issues with specific template
configurations.
Fixes all our Go file imports to match the preferred spec that we've _mostly_ been using. For example:
```
import (
"context"
"time"
"github.com/prometheus/client_golang/prometheus"
"golang.org/x/xerrors"
"gopkg.in/natefinch/lumberjack.v2"
"cdr.dev/slog/v3"
"github.com/coder/coder/v2/codersdk/agentsdk"
"github.com/coder/serpent"
)
```

This PR makes the change across the codebase. The PR in the stack above modifies our formatting to maintain this state of affairs, and is a separate PR so it's possible to review that one in detail.
Upgrades to slog v3 which includes a small, but backward incompatible API change to the acceptible call arguments when logging. This change allows us to verify via compile time type checking that arguments are correct and won't cause a panic, as was possible in slog v1, which this replaces (v2 was tagged but never used in coder/coder).
It also updates dependencies that also use slog and were updated.
I've left the `aibridge` dependency as a commit SHA, under the assumption that the team there (cc @pawbana @dannykopping ) will tag and update the dependency soon and on their own schedule.
Other dependencies, I pushed new tags.
Add agent forwarding of boundary audit logs from workspaces to coderd
via agent API, and re-emission of boundary logs to coderd stderr. This
change adds a server to the workspace agent that always listens on a
unix socket for boundary to connect and send audit logs.
coderd log format example:
```
[API] 2025-12-23 18:31:46.755 [info] coderd.agentrpc: boundary_request owner=.. workspace_name=.. agent_name=.. decision=.. workspace_id=.. http_method=.. http_url=.. event_time=.. request_id=..

Add the AgentAPI changes to support the feature that transmits boundary
logs from workspaces to coderd via the agent API for eventual re-emission to
stderr. The API handlers are stubs for now because I'm trying to land
this feature from multiple smaller PRs.
High level architecture:
- Boundary records resource access in batches and sends proto message to
agent
- Agent proxies messages to coderd **(captured by the API changes in
this PR)**
- coderd re-emits logs to stderr

Closes#20399
To summarize the original commit messages:
- Do not log stats to the database.
- Return errors on the insight endpoints.
- Update the frontend to show those errors.
- Also fixes an issue with getting the user status count via codersdk,
since I added a test to ensure it was not disabled by this flag and it
was sending the wrong payload.
This PR piggy backs on the agent API cached workspace added in an earlier PR to provide a fast path for avoiding `GetWorkspaceByAgentID` calls in dbauthz's `GetWorkspaceAgentByID`. This query is not the most expensive, but has a significant call volume at ~16 million calls per week.

This PR piggy backs on the agent API cached workspace added in earlier PRs to provide a fast path for avoiding `GetWorkspaceByID` calls in `GetLatestWorkspaceBuildByWorkspaceID` via injection of the workspaces RBAC object into the context. We can do this from the `agentConnectionMonitor` easily since we already cache the workspace.

The agentapi context needs to be a context with some amount of
authorization attached to it via the context so that the cache refresh
routine can fetch the workspace from the db via GetWorkspaceForAgentID.

This should resolve https://github.com/coder/internal/issues/728 by
refactoring the ResourceMonitorAPI struct to only require querying the
resource monitor once for memory and once for volumes, then using the
stored monitors on the API struct from that point on. This should
eliminate the vast majority of calls to `GetWorkspaceByAgentID` and
`FetchVolumesResourceMonitorsUpdatedAfter`/`FetchMemoryResourceMonitorsUpdatedAfter`
(millions of calls per week).
Tests passed, and I ran an instance of coder via a workspace with a
template that added resource monitoring every 10s. Note that this is the
default docker container, so there are other sources of
`GetWorkspaceByAgentID` db queries. Note that this workspace was running
for ~15 minutes at the time I gathered this data.
Over 30s for the `ResourceMonitor` calls:
```

- Ignore errors when reporting a connection from the server, just log
them instead
- Translate connection log IP `localhost` to `127.0.0.1` on both the
server and the agent
Note that the temporary fix for converting invalid IPs to localhost is
not required in main since the database no longer forbids NULL for the
IP column since https://github.com/coder/coder/pull/19788

## Summary
In this pull request we're removing `agent_name` from subdomains in APP
urls when an `app` is used in the subdomain. `agent_names` will still be
used when a `port` is used in the subdomain.
Closes: https://github.com/coder/coder/issues/18485
### Changes
- Updated regex to support an optional agent name
- Added logic to support checking the app slug for a matching port
(e.g., 8080 or 8080s)
### Testing
- Updated all tests to support an optional `agent_name`
At the moment, the loop which retrieves and updates the values of the
agents metrics excessively calls `GetUserByID` (a DB query). First it
retrieves a list of all workspaces, filtering out inactive agents (not
entirely clear to me whether this is non-running workspaces, or just
dead agents), and then iterates over those workspaces to get the rest of
the relevant data for the metrics. The next call is `GetUserByID` for
`workspace.OwnerID`. This is unnecessary because the `workspaces_visible` view we pull workspaces from has already been joined with the users table to get the username/name/etc.
This should at least partially resolve

### Breaking Change (changelog note):
> User connections to workspaces, and the opening of workspace apps or ports will no longer create entries in the audit log. Those events will now be included in the 'Connection Log'.
Please see the 'Connection Log' page in the dashboard, and the Connection Log [documentation](https://coder.com/docs/admin/monitoring/connection-logs) for details. Those with permission to view the Audit Log will also be able to view the Connection Log. The new Connection Log has the same licensing restrictions as the Audit Log, and requires a Premium Coder deployment.
### Context
This is the first PR of a few for moving connection events out of the audit log, and into a new database table and web UI page called the 'Connection Log'.
This PR:
- Creates the new table
- Adds and tests queries for inserting and reading, including reading with an RBAC filter.
- Implements the corresponding RBAC changes, such that anyone who can view the audit log can read from the table
- Implements, under the enterprise package, a `ConnectionLogger` abstraction to replace the `Auditor` abstraction for these logs. (No-op'd in AGPL, like the `Auditor`)
- Routes SSH connection and Workspace App events into the new `ConnectionLogger`
- Updates all existing tests to check the values of the `ConnectionLogger` instead of the `Auditor`.
Future PRs:
- Add filtering to the query
- Add an enterprise endpoint to query the new table
- Write a query to delete old events from the audit log, call it from dbpurge.
- Implement a table in the Web UI for viewing connection logs.
> [!NOTE]
> The PRs in this stack obviously won't be (completely) atomic. Whilst they'll each pass CI, the stack is designed to be merged all at once. I'm splitting them up for the sake of those reviewing, and so changes can be reviewed as early as possible. Despite this, it's really hard to make this PR any smaller than it already is. I'll be keeping it in draft until it's actually ready to merge.
The incorrect assumption that slugs were unique per-agent was made when
the subagent API was implemented. Whilst this PR doesn't completely
enforce that, we instead compute a stable hash to prefix the slug that
should provide a reasonable level of probability that the slug will be
unique.
Deletion of data is uncommon in our database, so the introduction of sub agents
and the deletion of them introduced issues with foreign key assumptions, as can
be seen in coder/internal#685. We could have only addressed the specific case by
allowing cascade deletion of stats as well as handling in the stats collector,
but it's unclear how many more such edge-cases we could run into.
In this change, we mark the rows as deleted via boolean instead, and filter them
out in all relevant queries.
Fixescoder/internal#685
It unfortunately doesn't seem possible, even with a custom ruleguard rule, to mark a function as requiring it's return value be used, it looks like you have to go all in on a linter that rejects *any* unused return values.
Completely missed this in the original PR for adding support for
creating sub agents. This now allows specifying a list of display apps
to be added to the agent.

Implement the `coderd` side of the AgentAPI for the upcoming
dev-container agents work.
`agent/agenttest/client.go` is left unimplemented for a future PR
working to implement the agent side of this feature.
# Use workspace.OwnerUsername instead of fetching the owner
This PR optimizes the agent API by using the `workspace.OwnerUsername` field directly instead of making an additional database query to fetch the owner's username. The change removes the need to call `GetUserByID` in the manifest API and workspace agent RPC endpoints.
An issue arose when the agent token was scoped without access to user data (`api_key_scope = "no_user_data"`), causing the agent to fail to fetch the manifest due to an RBAC issue.
