Twelve hosts running six services read as somebody's side project. Fifty hosts across twenty-one services read as an estate, which is what a visitor is trying to see themselves in. Thirty-one Linux, eighteen Windows, one Linux host whose agent is gone. The proportions are the point: Windows now carries Active Directory, IIS, SQL Server, Exchange, file shares, Remote Desktop, print, WSUS and SCCM rather than appearing as a Security channel on one box. Linux gains a load-balancer tier, an outbound proxy, MySQL beside Postgres, RabbitMQ, Elasticsearch, three Kubernetes nodes, CI, Vault, OpenLDAP, BIND and a backup server. Fifteen new generators, each writing what the real daemon writes -- HAProxy's timing quintuple, MySQL slow-query blocks, W3C extended format for IIS, kubelet PLEG lines, BIND query logging with NXDOMAIN, Squid's TCP_DENIED, SQL Server deadlock and I/O-stall messages -- with the structured fields carried in attributes so both halves of the query language have something to work on. Three things found while doing it, each of which would have shipped as a quiet wrongness: linuxHosts() decided Windows by `service == "eventlog"`. That held while eventlog was the only Windows role; with IIS and SQL Server on Windows it would have given every one of them a journald system stream -- sshd and UFW lines on a Windows box. It now decides from `os`. worker-02 lost its filling disk when the fleet was rewritten, which is the story worker-disk-filling thresholds on. Restored at its original rate, with a comment saying why it cannot move. Five dashboard panels were written as `timechart`, which this query language does not have -- its stages are where/stats/sort/fields/head/ tail. They are raw ClickHouse SQL now, which the reference recommends for exactly this, and a `pie` panel was dropped before it shipped because the web's VizType union has no such member even though the API accepts one. Five new dashboards: platform/Kubernetes, directory and DNS, messaging and search, the Windows server estate, and edge/proxy. Every panel was checked against the language's real stage list and the web's real viz types. Volume roughly quadruples: about 316 records/minute at rate-scale 1, and 1.9M per nightly reset at the demo's own settings against about 0.5M before. ClickHouse will not notice; reset time and disk on the demo box might, so the README says so and names RATE_SCALE as the lever.
hack
Local developer tooling that isn't part of any shipped component — scripts
you run against your own machine/dev stack, not code that ends up in a
container image (except dev-certs' output, which mounts into the
ingest container).
Not one of the top-level directories in the original monorepo scaffold —
added because dev-only mTLS cert generation didn't have a natural home in
/deploy (real deployment manifests), /transport, or any other existing
component. /hack is the conventional name for this in a lot of larger Go
monorepos (Kubernetes among them).
dev-certs/— generates a throwaway CA + server/client cert pair for local mTLS between the agent and ingest. See/docs/phase-0-runbook.mdfor when to run it.windows-fixture/— sends synthetic Windows Event Log-shaped records directly toingest, bypassing the real Windows agent. Tests whether the pipeline handles Windows-shaped data; doesn't test the realEvtSubscribe/ETW integration, which needs actual Windows. See/docs/phase-1-runbook.md.demo-simulator/— the public demo's synthetic world: a fictional fleet whose agents check in, report CPU/memory/disk, and ship realistically shaped logs for eight services. Backfills a window of history, then keeps generating in real time. Distinct frombenchmark-fixture/(volume, for the Phase 2 latency benchmark) andwindows-fixture/(correctness, for the Windows ingest path).check-web-routes.sh— assertsweb/nginx.conf's hand-maintained route allowlists still matchweb/src/routes.nginx.conf404s unknown paths, so it has to name the routes that have no prerendered file to match (dynamic ones, and any route withoutprerender = true). Drift here breaks production only — dev andnpm run previewnever readnginx.conf— so this runs in CI, likecheck-tenant-boundary.sh.demo-seed/— the rest of the demo deployment: its reset script, dashboards, alert rules, and the systemd unit that runsdemo-simulator.
