The table walk stopped after 64 raw entries, counting the RAM disks, loops,
partitions and md arrays that rows_like then drops, so a Synology's eighth
disk was never reached. The walk is now bounded at 1,024 entries per column;
64 still caps the rows kept.
ADM labels its disks "Disk0".."Disk4" while their indexes run 1..5; the
Asustor disk table now names each row by its index ("Disk 1"). Keys are
unchanged, so history carries on.

A preset can now read a vendor's tables: one row per disk, volume, fan or
sensor. The scheduled poll discovers the rows by walking the device: on its
first poll, after a save, and then hourly, and only while it answers. Each row
becomes readings named by the device's own labels ("Disk 1 status"). Only the
columns a row answered are asked for.
A vendor status, whether a code (Synology) or a word (Asustor), is a state
reading. It is stored as a level (0 OK, 1 busy, 2 warning, 3 failed), so one
alert rule covers any vendor, and shown in the device's own word.
- Synology: system, power and fan status and temperature; per disk: status,
health, temperature and bad sectors; per volume: RAID state (scrubbing,
parity check, rebuild, degraded), free space and size.
- Asustor: per disk: status, SMART and temperature; per volume: status, free
space and size; CPU and system temperature, free memory and fans.
From ADM's ASUSTOR-DISK-MIB and ASUSTOR-SYSTEM-MIB.
- Linux server: plus each physical disk's 1-minute busy % (UCD-DISKIO-MIB).
Migration snmp_002_table_rows adds tables, tables_at and texts to

A new plan's last_slot_at holds the moment it was made, so its first

A Traefik that hasn't restarted keeps reporting the certificate it
replaced, so codex.fabledsword.com's old one (21 days left) was listed
beside its renewal (81 days) and would have raised an expiry warning on
2026-10-22. A reported certificate whose every name a later-expiring
one covers is now old, on the page, the widget, the overview and MCP.
list_certificates takes `limit` (default 100) with total/truncated, and
says how many served certificates no HTTP router uses (`unrouted`).

Each source in an anomaly's `around` was cut to its oldest 40 with
nothing in the reply to say so; on a busy host the events nearest the
occurrence were the ones dropped. Each source now keeps the 40 nearest
the occurrence's start, and `around_left_out` counts the rest. Sources
return everything their bounded query read (Docker and the host agent
no longer cut at 40 and 20 themselves), so the count is honest.

All 16 Traefik 4xx anomalies on 2026-10-15 came back with nothing
around them, though 15 were Steward's own restarts. A router has no
host, and every events source was read by host.
- Core: each break of more than 90 s in Steward's once-a-minute health
sample is a "steward" event beside every anomaly, placed or not.
- Plugins: an optional mcp_resource_events(db, source, resource, since,
until) for a resource with no host. Traefik's gives the container
events of the swarm service behind a router, on any host.

One 502 among about 70 requests read steward@swarm critical at 1.4%:

fail" (traefik.threshold.min_5xx, default 3), must also be reached in
the 15-minute window; the 0.1% cutoff still catches a busy router.

Two 500s of about sixteen requests graded roundtable@swarm critical at

Through one address Steward read whichever replica answered, and with
host-mode ports behind a keepalived VIP that can be the replica serving
nothing: since the 18:43 restart every scrape landed on Docker03's idle
Traefik, which has no traefik_service_* series, so no router was stored.
A metrics_url host name that resolves to several addresses (a swarm
service's tasks.<service>, a Kubernetes headless Service, round-robin DNS)
is now scraped address by address, with the original Host header and TLS
name. Answers from one process are kept once; a replica that doesn't answer
is skipped with a warning. Requests, bytes and latency buckets are summed
over the replicas that have a baseline, so the sum's rise is the sum of each
one's own rise; certificates are listed once; Traefik's own figures add
connections and memory and keep the newest reload. A name with one address
is one scrape, as before.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
One metrics URL can reach several Traefik processes: a swarm service's
replicas behind the routing mesh or its VIP, a Kubernetes Service's pods,
a keepalived pair after failover, or the same Traefik after a restart.
Each keeps its own counters, so comparing one with another read the second
one's lifetime totals as new traffic: retired routers flashed 100% 502 and
an idle router showed 834 req/s whenever the scrape moved to the other
replica.
Each scrape is now keyed by Traefik's process_start_time_seconds and
compared only with the same process's previous scrape. A process seen for
the first time (or not in the last hour) sets its baseline and counts
nothing. Without a start time every scrape is one process, as before.

The snmp plugin registers list_snmp_devices and get_snmp_device; the
prometheus plugin registers list_prometheus_targets and
get_prometheus_target. Both are viewer-level, read what the poller and
scraper stored, and exist only while their plugin is enabled.
get_overview names a device or target whose last poll or scrape failed;
stale, pending and off are left out.
A device's community and v3 keys and a target's token are never
returned, and a password in a target URL is masked.

get_network gives the WAN, clients, Wi-Fi networks, speed tests and devices
by status; list_devices, list_clients (everyone seen, or the newest poll's
top talkers), list_network_events, list_alarms and get_network_config
(networks, port forwards, firewall rules) read what the poller stored.
get_overview names the WAN down while the poll is current, a device offline
or degraded that the controller still reports, and active alarms.

list_routers grades every router as the Traefik page does (the last 15
minutes, 5xx on its cutoff, 4xx and p95 against the router's normal) and
gives a troubled one its status codes, what they mean and the swarm
service behind it. get_router adds its history, codes, normal and
anomalies; list_certificates the served certificates and the routers they
cover; get_traffic the access log's clients, countries and routers.
get_overview names a router answering 5xx and a certificate near expiry.
The access-log aggregation moves into routes.summarize_access, shared by
the traffic page and get_traffic.

get_anomaly gives each occurrence against what is usual at that hour, the
metric around the newest one with its normal, what else happened on the
resource's host around each occurrence (alert transitions, Ansible runs,
other anomalies there and a count elsewhere, plus plugins' own events
through a new mcp_events hook: the host agent's maintenance jobs and
downtime, Docker's container starts, deaths and OOM kills), and how earlier
anomalies on the same metric were judged.
get_metric_normal reads the learned slots and the level that would be
flagged. review_anomaly takes one id or several, all or nothing, with a
note. get_anomaly_settings and (admin) set_anomaly_settings read and change
the review window and each normal's floor, as Settings → Thresholds does.
metric_series.points takes an optional `until`; core.alerts gains
host_of_resource; floor_setting names its floor.

#5835 "MCP: swarm nodes", step 2 of milestone 520. list_swarm_services
already listed every node (role, leader, availability, status); the
audit missed it. What was missing:
- Each node row carries `host_id` (the Steward host of that name) and
`maintenance` (the state of a maintenance job running on it), so an
agent can go node -> get_host / get_maintenance_job.
- get_overview names a node whose status isn't ready, unless its host
has a maintenance job running (rebooting on purpose).
- Drained alone is not a finding: VDNT-Util01 is a manager kept drained
on purpose (#5777), and a drain a failed job left behind is already
that job's maintenance_failed finding.
unique_nodes() keeps the newest report of each node, as the list did.

#5834 "The host agent is always on, and the MCP sees a host's
maintenance", step 1 of milestone 520 "The MCP sees what Steward has
grown".
The host agent is a core system (operator, 2026-10-15: "it's very core
to the functionality of Steward as a whole and shouldn't be considered
something that can be toggled off"). ALWAYS_ON_PLUGINS in core settings
makes to_plugins_cfg report it enabled whatever its stored row says, so
it always loads and its MCP tools are always listed. Settings -> Plugins
shows it as "Built in: always on" with no switch, and a save keeps it
enabled. Its code and URLs stay under plugins/host_agent: every
installed agent posts to /plugins/host_agent/ingest.
Maintenance through the MCP:
- list_maintenance_plans: each plan's group, weekly slot, reboot policy,
next slot, and its latest run (hosts, how far it got, who it skipped
and why, how it ended).
- get_maintenance_job(host | job): a host's jobs, newest and running
first, or one job: state, packages updated, reboot, drained by, why it
failed, when its current state times out.
- run_maintenance(host, reboot="if_required" | "never"): admin, as the
host page's Update now; refuses a busy host or one with no helper;
audited "<user> via MCP".
- The overview names a host whose latest job in the last week failed or
timed out.

Agent 1.21.0. The hourly update check now covers the package managers
beyond apt and dnf (#5803 "The agent's update check reads pacman,
zypper and yum"):
- yum: `yum -C check-update`, `updateinfo list security`,
`needs-restarting -r`, as dnf.
- zypper: `--no-refresh list-updates` (`--dup` on Tumbleweed),
needed security patches from `list-patches --category security`,
and `zypper needs-rebooting`.
- pacman: `checkupdates` from pacman-contrib, which install-deps.sh now
installs. pacman has no security notion; a reboot is required once
the running kernel's /usr/lib/modules/<release> is gone.
The checks sit in one UPDATE_CHECKS table, and a failure names its
manager.
The root helper's update runs on the same hosts (#5804 "The scheduled
update runs on pacman, zypper and yum hosts"): yum upgrade, zypper
refresh + update (dup on Tumbleweed, with 102/103 counted as success),
pacman -Syu. Each step carries a label so a failure says which one,
and the reboot check reads zypper and the pacman kernel too.

Routers: a router in trouble reads 'started 2h ago' or 'all of the last

An agent keeps its log cursors in memory, so after a restart it seeds each
container from its last 50 lines, which Steward already holds; docker_logs
has no unique key, so every update or reboot doubled them. The ingest now
reads what it already has for each container over the batch's own span,
in one query, and skips those lines. A push of new lines overlaps nothing.

smartctl reports every disk behind a PERC/MegaRAID controller as /dev/bus/0
with type megaraid,N; the helper named a drive by its path alone, so all of
VDNT-Docker02's and Docker03's disks read as one drive "0", each overwriting
the last. The slot is now part of the name (bus0-megaraid3), and Steward gives
a repeated name an ordinal so two drives never share a series. Agent 1.20.1.
fix(ansible): Steward stopping mid-run logs no traceback (#5749)
The run's done-callback called exception() on a cancelled task, which raises;
it now logs a run cut short by shutdown at INFO. A finished run's in-memory
state is dropped by a timer rather than a sleeping task, which shutdown found
still pending.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The root helper gains one read-only action, `drives`: it finds the drives
itself (smartctl --scan-open), reads each as JSON, and writes a summary the
agent carries on every sample (agent 1.20.0). Steward judges the figures in
drives.py (failing / worn / watch / ok / no SMART / unreadable), records them
per drive and as host roll-ups for covering rules, keeps the newest report on
the registration and lists it on the host page.
install-deps.sh installs smartmontools with apt, dnf, yum, zypper, pacman or
apk, run by install.sh and every agent playbook; one it can't install is
reported, never fatal.

On 2026-10-14 nine swarm services sat at 0/1 and nothing fired. From each
manager's swarm report the docker plugin now records three figures on
resource "swarm": swarm_services_short, swarm_nodes_down and
swarm_managers_unreachable. Drained nodes are left out of the last two,
since a drain is deliberate. The figures are recorded at most once every
30 s whichever manager reported, and are offered to alert rules.
Agent 1.19.0 sends each manager's ManagerStatus.Reachability. Older agents
fall back to the node's status.
A maintenance job on a swarm node also keeps a window over docker/swarm,
so its drain and reboot hold those alerts until the job ends.

temp_c_max was recorded on every ingest, but host_agent didn't offer it
to rules, so "host running hot" couldn't be watched. The catalog guard
didn't see the row(...) helper ingest builds its rows with. Now offered:
temp_c_max, temp_c per sensor, and network and disk throughput per host,
interface and disk. A new guard holds every literal row(...) name to the
catalog, except NOT_ALERTABLE, where each exclusion is given a reason.
temp_c_max reads in °C.

On the live instance the hourly refresh took 3 min 8 s, averaging a week of
raw temp_c samples each time. The hourly averages are now kept in memory.
The first refresh after startup reads the whole window. Each later one reads
raw samples from the start of the hour the last read ended in, so the hour
that was still filling is read again whole. merge_hours folds the new rows
in and drops hours older than the window.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Rollups exist only for hours older than the raw window (7 days by default),
so the first deploy read an empty week and judged nothing. refresh now
averages the raw samples by the hour and adds any rolled-up hours in the
window. Sensors are named from plugin_metric_latest, so each series is read
through its index instead of a pattern over every host_agent row. An
integration test covers both halves against Postgres.

A board's spare thermistor inputs report whatever an open input reads, and
the value rule from #5759 only catches the impossible ones. Once an hour,
sensors.refresh judges each sensor against the host's CPU (Package id N,
Tctl/Tdie/TccdN, PECI Agent N) over a week of hourly averages. A sensor is
ruled out if it falls as the CPU warms (r <= -0.5) or holds within 0.5 °C
while the CPU moved 10 °C or more. A judgment needs at least 72 shared hours.
The host temperature leaves judged sensors out at ingest. The host page
lists them under "Not counted", with each reason given once.

- #5780 "The error-pages service is graded on other routers' errors". The
Traefik scrape reads which services an errors middleware sends to, and
grades them healthy: their 4xx and 5xx are the codes of the errors they
cover for, already graded on the routers that failed.
- #5781 "The Maintenance failed rules sit at no data until a host has had
a maintenance job". Every host with an agent reads 0 until a job fails.
- #5782 "VDNT-Util01's host page lists SYSTIN at 115 °C in red". The host

#5712 "Each router problem says what it means, whether it's real, and what
to do". A problem card now names its kind and reads its codes:
- Server errors: 500 means the app is failing; 502/503/504 means Traefik
couldn't reach it or it timed out.
- Client errors: 404 scanners, a 401/403 login wall, 429 rate limiting, or
499 clients giving up on a slow app.
- Slow: p95 against p50.
Each card says whether the problem is likely real, and ends with one next
step. A fault links to the swarm service behind the router, matched by
name, and traffic links to Settings → Thresholds. The wording lives in
plugins/traefik/meaning.py.
The plugin manager now hands out a loaded plugin's submodule
(loaded_plugin_submodule), so Traefik and host_agent reach Docker's
models the same way (#5775).

#5777 "Maintenance would make a node the operator keeps drained active after

ready but not active.

Importing plugins.docker.models by path defines its tables a second time,

#5768 "A maintenance cadence: a group's updates and reboots, one host at a

in a time zone, a window and a reboot policy (only when required by
default). At its slot a run takes the group's hosts in order and gives each
a #5767 maintenance job. The next host starts only when the last is back in
service: its agent is posting and, for a swarm node, the node is active and
every replicated service is at its replicas. A failure stops the run, and
no host is started once the window has passed. A host's latest failure
shows as host_agent/<host>/maintenance_failed, for an ordinary alert rule.

#5767 "Steward hands a host a maintenance job and follows it to the end,
through its own restarts", milestone 514.
A host_maintenance_jobs row per job: queued → updating → [draining →]
rebooting → [undraining →] done, or failed / timed_out. Steward's answer to
an ingest post carries the step that host's agent should carry out now; the
agent (1.18.0) leaves each step id for the root helper once, and the helper
refuses an id it already ran, so repeats are harmless. Results come back as
the #5766 maintenance events, matched by step id; the reboot completes when
the host's `started` event has a boot_at after the reboot was handed out.
The job reboots only when the update says one is needed (or never, if asked).
A swarm node is drained first by itself if it's a manager or by a manager
with the helper, and made active after; with no manager to drain it the job
is refused. A minute tick times out a job past its state's deadline. A
maintenance window over host_agent/<host> lasts the rest of the job.
Everything is on the row, so a Steward restart, or the reboot of the host
Steward runs on, resumes from the next post. Ingest runs it in its own
savepoint so a job going wrong never costs the samples.
The Agent panel leads with a running job and says what a finished one did;
Manage agent has Update now (with "never reboot"), or says why a job can't
start. Integration test: hand off, Steward restarts, the post-boot events
close the job.

#5766 "A root helper the agent can start, for a fixed set of maintenance
actions and nothing else", milestone 514.
The agent runs unprivileged under NoNewPrivileges, so it can't update or
reboot its host. It now leaves a request in /var/lib/steward-agent/requests,
the one path its unit lets it write; steward-maint.path starts maint.py as
root, which reads it without following links, accepts only update, reboot,
drain or undrain, deletes it, and writes the outcome to
/var/lib/steward-maint/results. The agent (1.17.0) reports each new result
state once as a `maintenance` event, re-checks pending updates when an update
finishes, and says in its metadata whether the helper is installed.
The units and the helper are served from one copy at
/plugins/host_agent/files/<name> (a fixed list), and install.sh plus the
install, provision and update playbooks all fetch them, replacing three
inline copies of the unit. Update agent installs the helper on existing
hosts; the Agent panel says under Manage agent whether it is there.
Steward handing out jobs is #5767; the cadence is #5768.

are read every sample.
- Ingest records updates_pending, updates_security and reboot_required for

- One shared reader, _docker_get: each answer has an overall deadline and a
byte cap, not only a per-recv timeout. A trickling or endless body is cut
off (15 s / 32 MiB for JSON, 5 s / 4 MiB for a log read).
- Container logs: since the cursor but only the newest 2,000 lines, all
within 10 s. A note says when older lines were skipped, and a container
whose answer is too big skips ahead to now instead of re-reading its
backlog every interval.
- The agent reports its own RSS and CPU; Steward records agent_rss_bytes
and agent_cpu_pct, so a runaway agent shows before it goes silent.

(on SIGTERM, with whether systemd says the host is going down) and
lost_contact (from its first unanswered post to the one carrying it).
Steward keeps them as the host's downtime (host_downtime): reboot,
agent_stop, unclean (a boot after the agent was last heard that nobody
announced) or lost_contact. Retried posts apply once.
An announced stop explains the silence for reboot_grace_seconds (Settings
-> Plugins -> host_agent, 10 minutes): seconds_since_seen reads 0 until
then, and the host's other rules go quiet with it (agents_away beside
#5721's registry). Past the grace, agent offline fires.
The host's Agent card lists the last 7 days of downtime. Rows are pruned
at data.retention_days.

VDNT-Util01's / ran out of inodes (956 free of 60.8M) with 274G of space
left; every file create failed and Steward's page read healthy at 66%.
- Agent 1.13.0 reports each mount's inodes (statvfs; a filesystem reporting
none, like btrfs, is left without).
- Ingest records inodes_used_pct per mount, and disk_used_pct_worst is the
fullest mount by space or inodes, so existing disk-full rules and the
overview see it.
- The host's health strip, the Hosts widget and the host glance grade / by
whichever is fuller and name inodes when they are ("Disk / 66% · inodes
100%", "Inodes on / ... past its critical threshold").
Hosts pick up the inode figures once their agent is updated to 1.13.0.

Nine services that lost tasks in one node's bad three minutes stayed on the
overview as warnings for a day, 17 hours after they recovered. Against the
UI ruling (only what is current on the dashboard), a service running all its
replicas is now history: its failed tasks stay on the Docker page, not on
the overview or the dashboard's failed count. Services still short of
replicas that started failing within five minutes of each other read as one
finding naming them, dated from the first.

VDNT-Docker03's silent agent read as three overview findings (agent offline,
agent stale, the disk rule's no-data) and every drop emailed the disk rule's
silence and return on top of agent offline.
- The host agent registers its heartbeat (seconds_since_seen) and the
sources it carries (host_agent, docker). While a host's agent is past its
offline window, its other rules' no_data is recorded "while its agent is
offline" and not emailed, nor is their quiet return; a return past a
threshold still fires.
- The overview folds those rules under the host's agent-offline finding
("also silent with it: ..."), and a stale agent whose agent-offline alert
is active is that alert's finding, not a second one.

Counting every agent's silence from when Steward started watching again
(#5441) read an agent that was already gone as just seen: its agent-offline
alert resolved at 0 s and fired again three minutes later, two false emails
per restart (VDNT-Docker03, four times in a day). An agent whose last
recorded seconds_since_seen was already past the offline window now keeps
counting its whole silence; one that was fine when Steward stopped still
counts from the restart, so Steward's own downtime still fires nothing.

CI 9128: the host vitals and monitor templates required the new grades, so
callers (and tests) that render them without one failed; they now fall back
to status_class. The new integration test read outside begin(), which
autobegan the session.
