LiteLLM Operations — Self-Heal (Remediation)

Architecture (v4.0.0 — Direct: nginx → LiteLLM → GPU)

Request → nginx:80 → LiteLLM:4000 → GPU(llama-server, parallel 2)

  harness-router :9000 — DECOMMISSIONED 2026-09-11 (container, image
  and config removed). nginx routes /v1 → LiteLLM directly.
  Router slot booking + circuit breakers replaced by
  LiteLLM native fallbacks + timeouts.

Parameters

• public_url: string — Public LiteLLM URL (default: "https://litellm.sysloggh.net")
• backend_host: string — Internal CT host (default: "192.168.68.116")
• auth_host: string — Authentik OIDC server (default: "192.168.68.11")
• gpu_hosts: array — GPU inference hosts (default: ["192.168.68.8", "192.168.68.110", "192.168.68.15"])
• gpu_dashboard_url: string — Fleet dashboard (default: "http://192.168.68.24:9100")
• grafana_url: string — Grafana dashboards (default: "http://192.168.68.116:3001")

GPU Fleet Topology

Host	IP	Hardware	Role
llm-gpu	192.168.68.8	NVIDIA RTX 3090 (24 GB)	heavy reasoning (gpu-dense)
ocu-llm	192.168.68.110	NVIDIA RTX 5070 (12 GB)	vision / web extract / light tasks (gpu-vision)
amdpve	192.168.68.15	AMD Strix Halo 64GB UMA	compression (strix-moe)

Verified on the ground 2026-07-16. The legacy name ornith-1.0-35b does NOT exist in LiteLLM and must not be referenced.

LiteLLM Model Surface

Single source of truth for models, aliases, rpm caps, weights and fallback chains: CT 116 /opt/inference-harness/litellm_config.yaml. Do not duplicate those values in contracts — read them there. Do not re-add retired names (gemma-4-12b, gpu-light, crew-auto).

Alias Surface

Alias	Serves	Where	Kind
gpu-dense	heavy reasoning	RTX 3090 (192.168.68.8)	direct alias
gpu-vision	vision / web extract / light tasks	RTX 5070 (192.168.68.110)	direct alias AND syslog-auto pool member
strix-moe	compression (MoE)	Strix Halo (192.168.68.15)	direct alias
syslog-auto	balanced default	weighted pool across the three GPU hosts	pool router

Context Cap Split (2026-08-20; crew cap RETIRED)

• Abiba (firstmate): 128K uncapped — unlimited context for primary workloads
• Hermes agents (mumuni, tanko, koby, koonimo): 128K uncapped
• Crewmates (ops, tune, verify, auth-keys, build): the 64K cap was retired together with the crew-auto alias; NO context cap is currently in force.

The 64K crew cap was retired with crew-auto (2026-09-12). No limit is currently in force; reinstating one would need per-key model limits as a separate, deliberately-scoped change.

• Key scoping: /v1/models is key-scoped, so the set a caller sees must be read with a named key rather than assumed — a monitor key, an agent key, and the master key can each return a different set. Agents should use the stable aliases (strix-moe, gpu-vision, gpu-dense) rather than raw model names, so model swaps don't break them.
• NEVER use litellm_proxy_master_key (the sk-litellm-... master key) for inference. It is for admin endpoints only (/key/list, /key/generate, /key/info). All inference — agent traffic, health-check model tests, monitor scripts — uses agent-specific keys. The health-check script's model tests use a dedicated monitor agent key stored at /etc/litellm-monitor.env on CT 116 (root-only, chmod 600); /key/list is the only call that legitimately uses $MASTER_KEY.

Re-scope note (2026-09-12): the fallback-chain and per-model timeout tables were removed by the single-source-of-truth re-scope; read those values from the CT 116 config named above rather than from this contract.

Containers on CT 116

Container	Image	Port	Health Check
harness-litellm	ghcr.io/docker.litellm.ai/berriai/litellm:1.99.1	:4000→:4000	/health/liveliness
harness-nginx	nginx:alpine	:80	HTTP 200 on /health
harness-postgres	postgres:16-alpine	:5432	pg_isready
harness-redis	redis:7-alpine	:6379	PING
harness-dashboard	inference-harness-dashboard	:3000	/health
harness-grafana	grafana/grafana	:3000→:3001	/api/health
harness-prometheus	prom/prometheus	:9090	/-/healthy
harness-docker-stats	python:3.12-alpine	—	container stats exporter
harness-pve-exporter	prompve/prometheus-pve-exporter	—	Proxmox metrics → Prometheus

Script Operations (synced 2026-07-16)

• Health-check script (/opt/inference-harness/scripts/litellm-health-check.sh on CT 116): gpu-fleet check fails only on critical alerts (warnings are informational). Tests strix-moe (not ornith-1.0-35b).
• GPU monitor (/root/scripts/gpu-monitor-server.py on pi .24): runs as systemd unit gpu-monitor.service (was bare & process). gpu_count includes Strix Halo (was 2, now 3). VRAM alert thresholds: warning 93%, critical 97% (raised from 90/95 — 128K context steady-state is ~70% on RTX 3090, not a fault).
• Agent key monitor (/root/scripts/agent-health-check.py on pi .24, cron */10): v4 (2026-09-10) — vault-backed agents (tanko/koby/koonimo) read their agent-specific {NAME}_LITELLM_API_KEY from Infisical vault (not the shared master key); abiba (pi agent) reads LITELLM_API_KEY from its local /root/.pi/agent/env.sh (#735 — moved out of shared /root/.bashrc), not from the vault. Abiba is pi-only since the harness purge, so its Hermes config/wrapper/gateway legs are skipped rather than reported as faults; koby is report-only (captain's 2026-08-17 ruling) — its findings go to the --json report_only array and are never counted as fleet failures or repaired, and its CT 111 liveness is probed on storepve (.6). Covers: LiteLLM keys, GPU ports, agent gateways, CT liveness (pct status on PVE nodes), config.yaml YAML integrity, wrapper/CLI integrity, vault secret non-emptiness checks. Every run/report carries the absolute execution path (script= + cwd=). The current fleet roster is owned by the script changelog (scripts/agent-health-check.py); mumuni is no longer probed from this host. Legacy tdunna/baggy replaced with canonical agent hostnames.
• Stale keys cleaned: daily-infra-report.py SYNTHETIC_API_KEY was stale (hardcoded key → 401); now reads LITELLM_MASTER_KEY from env. Deprecated scripts (router-original.py, router-phase0-backup.py, apply-fixes.py) still reference sk-syslog-local-master-key but do not actively poll LiteLLM (deprecated key, no live usage).

Maintains

• litellm-admin-ui: { status: "healthy", last_check: timestamp }
• litellm-api-docs: { status: "healthy", last_check: timestamp }
• litellm-containers: { status: "healthy", last_check: timestamp }
• litellm-oidc: { status: "healthy", last_check: timestamp }
• litellm-gpu-fleet: { status: "healthy", models: int, alerts: array }
• litellm-agent-keys: { count: int, valid: int }

Continuity

• Self-driven: check every 300 seconds
• Also wakes on user request
• On failure: re-check after 30s, escalate after 3 consecutive failures

Health Check

Health probes are owned by litellm-health.prose.md (dispatched as run contract: litellm-health). This contract owns remediation only — it does not re-specify the probes.

---

---

Remediation Rules

Rule 1: Container Not Healthy

Detect → docker compose up -d <container> → verify → log Escalate after 3 failures

Rule 2: Admin UI Non-200

Detect → restart harness-litellm → verify → log Escalate after 2 failures

Rule 3: Auth Unreachable

Detect → immediate escalate (external dependency)

Rule 4: Docs 404

Detect → fix DOCS_URL env var → verify → log

Rule 5: GPU Unreachable

Detect → SSH to GPU host fails or model not responding Fix → restart llama-server on host via SSH Escalate → immediately (downtime affects inference)

Rule 6: Model Not Responding

Detect → test prompt via LiteLLM returns non-200 Fix → restart llama-server on GPU host → verify Escalate → after 2 failed restarts

Rule 7: Router Returns 503 (All GPUs Saturated) — DEPRECATED

Router is no longer in the request path (2026-07-08). LiteLLM proxies directly to GPU. This rule is retained for reference but is inactive. If 503 errors occur, check LiteLLM timeouts and GPU health directly.

Rule 8: Agent Keys Invalid (401)

Detect → agents report auth errors Root cause → keys not in LiteLLM DB Fix → generate keys in LiteLLM via /key/generate → update /etc/environment on agent hosts Escalate → if SSH access unavailable, send Zulip DM

Rule 9: Stale Active Counter in Redis — DEPRECATED

Router no longer in path so router active-slot counters are unused. Rule retained for reference but inactive. harness-redis now serves only LiteLLM cache and rate-limit state; check the container if cache errors appear.

Reporting

Every remediation cycle produces a structured report:

1. Gitea Log Entry

Pushed to SyslogSolution/health-logs/litellm/{run_id}.json — versioned, searchable, not in graph.

2. Zulip DM to Owner

• issues_fixed > 0 — "🛠 LiteLLM Self-Heal — Fix Applied"
• issues_escalated > 0 — "⚠ LiteLLM Self-Heal — Needs Your Attention"
• Every 10th clean cycle — "✅ All Clear (10 checks passed)"

3. Daily Digest (end of day)

Summary of last 24 hours: total cycles, issues found/fixed/escalated, top actions, uptime.

4. Relay Message (if cross-agent)

If a fix requires another agent (e.g., Authentik restart), relay sent to responsible agent with full context.

gitea-logger Implementation

When this step executes, write the report JSON to a temp file and push to Gitea:

REPO="https://abiba-bot:${GITEA_PAT}@git.sysloggh.net/SyslogSolution/health-logs"
DIR="litellm"
FILE="${run_id}.json"
echo "${report_json}" > /tmp/${FILE}
(cd /tmp && git clone --depth 1 "${REPO}" && 
  cp ${FILE} health-logs/${DIR}/${FILE} && 
  cd health-logs && git add ${DIR}/${FILE} && 
  git commit -m "litellm-health: ${run_id}" && git push)
rm -rf /tmp/health-logs /tmp/${FILE}
