Per defect report 1154.msg (agent-health-gateway-leg-flap-20260913):
1. Add _ssh_retry() helper with one retry at longer timeout (25s)
2. Name probe target explicitly: ssh {user}@{host} <command>
3. Print probe-failed when first attempt fails, then retry
4. Only declare gateway-down after retry fails
5. Make Koby report-only explicit in output
Changes:
- check_agents(): all gateway probes now use _ssh_retry()
- All output lines name the probe target (ssh host:port)
- Koby's report-only status is explicit in output
- Never print bare "gateway down" — always name target and failure kind
Verified: koonimo shows "probe-failed" on first attempt (transient SSH),
retries at 25s, succeeds, reports ✅ koonimo: gw=running
Captain ruling 2026-09-10: Mumuni moved off this host onto her own container
(kagentz CT 105 on minipve, 192.168.68.14, dedicated `hermes` user) and is
monitored from her side. This host must not monitor anything Mumuni.
The stale probes fired false alerts repeatedly:
* scripts/zulip-monitor.sh ssh'd to root@192.168.68.24 for the
decommissioned deployment's ~/.hermes/gateway_state.json, read "unknown"
on every run, and posted a 🔴 "Mumuni (Hermes) Zulip state: unknown" DM +
#agent-hub stream alert each cycle.
* scripts/daily-infra-report.py published a matching "mumuni:unknown" row in
every digest.
Changes:
* zulip-monitor.sh: delete the "Platform B: Hermes (Mumuni)" leg and its
notify; keep the Zulip-server, Platform A pi/Abiba (bridge), Platform B
Tanko and Platform C Agent Zero legs. A comment records why the leg is
retired so it is not re-added. Also fixes SC2155 so shellcheck is clean.
* daily-infra-report.py: delete the .24 ~/.hermes/gateway_state.json agent
probe, its hermes --version probe, and the now-dead mumuni render branch.
Abiba (CT 100, its own .24 address) and Tanko legs unchanged; the PVE API
token name is untouched.
* zulip-health.prose.md (v3.1.0): drop the Mumuni-only B4 gateway-process,
B5 heartbeat and B6 response-delivery steps and the stale 192.168.68.24
references; state explicitly that Mumuni is not monitored from this host.
Tanko/Agent-Zero/bridge steps retained.
* agent-health-check.py: correct the v2 changelog roster comment that still
placed mumuni at .24/CT100. No behavior change — the mumuni probe was
already absent from the AGENTS dict; v5 changelog notes the correction.
Tests: tests/test_mumuni_monitor_removal.py pins the removal structurally and
behaviorally — the shipped zulip-monitor.sh is run in a sandbox (only its LOG
constant rewritten) with stub ssh/curl on PATH; the ssh stub records every
target host, so "never reaches .24" and "no Mumuni notify even on the alert
path" are asserted from observed behavior. A mutation check (re-inject the old
leg) fails the suite, so the guarantee is not vacuous.
Second probe-drift correction pass after #65/#66/#68. All four legs were stale
consumer expectations, not live faults.
1. scripts/agent-health-check.py (v4)
- abiba declared pi-only runtime (harness purge): Hermes-era gateway, config
and wrapper legs are skipped instead of failing.
- koby declared report_only (captain ruling 2026-08-17, Rule 17): every koby
leg is detected and reported, never counted as a fleet failure or repaired.
- koby's CT 111 mapping corrected to storepve (.6); the old amdpve mapping
made `pct status 111` fail and read as ct-unreachable.
- wrapper check no longer FAILs .env-based wrappers that legitimately never
invoke infisical (koonimo).
- keys load in main() (load_agent_keys) so the module is importable/testable.
- every run prints absolute execution provenance (script + cwd), in the header
and in --json.
Before: 6 FAILURE(S). After: 0 failures, koby reported read-only.
2. infrastructure-monitoring.prose.md
- PVE API probe repointed from CT 116 (no pveproxy, 000) to the five real
nodes on https://<node>:8006/api2/json/version, all 401 = alive.
- any-HTTP-response liveness rule added (401/3xx alive; 000/timeout = DOWN).
- LiteLLM health documented as 301 -> /litellm/health/liveliness, not bare 200.
3. gpu-monitor.prose.md
- GPU health probes on :8080 (or router /health/unified); bare port 80 on a
GPU host is forbidden (no listener -> false DEGRADED).
- router /health/unified 301 -> /gpu/gpu-data documented as alive.
- port-discipline + liveness rule + direct-fallback execution step.
4. Report provenance (all contracts)
- docs/AUTHORING-GUIDE.md documents the rule; scripts/prose-lint.sh enforces
that any **Report format** contract states an absolute path (pwd -P).
- provenance added to gpu-monitor, infrastructure-monitoring, proxmox-monitor.
Tests: tests/test_probe_drift.py (23 passed); prose-lint.sh clean + shellcheck
clean; CI frontmatter validation passes. Evidence with per-leg before/after and
absolute paths: docs/probe-drift-round2-evidence.md.
- GPU unit repoint verified live 2026-09-08: .8 rtx3090 probes
llama-chat-api.service (stale llama-server unit read inactive -> false
UNREACHABLE for a healthy process); .110 keeps llama-server.service
(ocu-llm VM), .15 keeps strix-server.service. is-active no longer
swallowed as SSH failure (|| true).
- check_agents: bind pid before the summary f-string so the non-report-only
path (abiba/koonimo) no longer raises UnboundLocalError (line 305 crash).
- abiba key leg: read LITELLM_API_KEY from /root/.pi/agent/env.sh (#735
moved creds out of shared /root/.bashrc); 'abiba NO KEY' gone on healthy
setup.
2dfc3e1 (PR #50's out-of-band squash) overwrote agent-health-check.py with
a version whose AGENTS dict was empty — the health check silently skipped
every agent since. Restore the pre-stomp roster verbatim: tanko (runtime:
dsh), abiba, koby, koonimo.
Also land two Tanko-DSH rows from PR #52 that the earlier merge missed:
- hermes-zulip-plugin live-state table (plugin retired on CT112)
- zulip-self-heal restart-services table (restart via DSH service, not
hermes gateway restart)
Mumuni rows from the branch were NOT restored: they carry pre-migration
CT100/.24 data, superseded by PRs #54-56 (Mumuni now on kagentz CT105/.14).
Closes the reland of PR #52's substance; the stale branch head stays closed.
Gaps fixed:
- Koby (.129) and Koonimo (.114) now have SSH hosts — no longer skipped
- Agent key lookup uses correct {NAME}_LITELLM_API_KEY format
- New CT liveness check via pct status on PVE nodes
- New config YAML integrity check via yaml.safe_load()
- New wrapper/CLI integrity check (hermes wrapper, infisical path, hermes-real)
- New vault secret non-emptiness check
- Ops escalation: failures produce ALERT lines for cron capture
Single non-disruptive script replacing 7 scattered Zulip health checks.
Checks every 10 min via cron, never restarts anything:
- LiteLLM key validation for all 4 Hermes agents
- GPU port conflict / ghost process detection
- Agent gateway liveness + Zulip streaming status
- Recent gateway error count
Port conflict detection added to all 3 GPU wrappers:
- .8 (qwen): wrapper detects ghost on port 8080 before starting
- .110 (gemma): same pattern
- .15 (ornith): port-cleanup.sh replaces blanket pkill -x llama-server
