# Playbook: day2_qwen38_ctx128k_rollback.yml
|
||||
# Purpose: Roll back Qwen3.8-27B-Q4_K_M ctx-size from 131072 back to 65536
|
||||
# on astro-orbiter's production router (port 8002).
|
||||
#
|
||||
# What this playbook does:
|
||||
# 1. Renders the updated llama-server-router-preset.ini.j2 (now with
|
||||
# llm_router_qwen38_ctx_size: 65536) to
|
||||
# /opt/llama-server-router-preset.ini.
|
||||
# 2. Restarts llama-server-router.service.
|
||||
# 3. Verifies the router loads Qwen3.8-27B at ctx=65536 in status.args.
|
||||
#
|
||||
# Context:
|
||||
# - t_441470b9 (2026-08-16): ctx-size bumped 32768 -> 131072. Verified VRAM
|
||||
# at 131072 ctx with only Qwen3.8 + nomic-embed co-resident: ~20,282 MiB
|
||||
# + 558 MiB = ~20.8 GB on 24 GB RTX 3090. Comfortably safe.
|
||||
# - t_72646029 (2026-08-17): Phi-3.5mini moved to GPU (n-gpu-layers=99)
|
||||
# to enable concurrent residency with CPU-offloaded Coder-14B and
|
||||
# Llama-3.1-8B. This added ~2GB CUDA context buffers for Phi + shifted
|
||||
# Phi's model weights onto the GPU (~3.8GB).
|
||||
# - NEW steady-state VRAM: Qwen3.8 @ 131072 ctx (~20,282 MiB) + nomic-embed
|
||||
# (~558 MiB) + Llama CUDA ctx (~1,706 MiB) + Coder CUDA ctx (~1,390 MiB)
|
||||
# = ~24,004 MiB. Adding Phi-3.5 (~3,800 MiB weights + ~1.4 GB CUDA ctx)
|
||||
# pushes total to ~29,000+ MiB — exceeding the 24,576 MiB RTX 3090 limit.
|
||||
# Qwen3.8-27B-131072 now fails to load (HTTP 500, OOM before llama.cpp
|
||||
# reaches the model-loading phase).
|
||||
# - FIX: reduce Qwen3.8 ctx-size 131072 -> 65536. This reduces KV cache
|
||||
# from ~6GB to ~3GB, freeing ~3GB of VRAM. New estimated steady-state:
|
||||
# Qwen3.8 @ 65536 ctx (~17,068 MiB) + nomic (~558) + Llama ctx (~1,706)
|
||||
# + Coder ctx (~1,390) + Phi-3.5 (~3,800 + ~1,400 CUDA ctx) = ~25,922 MiB.
|
||||
# Still over 24,576 — see "Phase 2" below for the secondary fix.
|
||||
#
|
||||
# IMPORTANT: Rolling back ctx-size alone may NOT be sufficient. The
|
||||
# hardware reference (astro-orbiter-hardware.md line 166, t_72646029)
|
||||
# states steady-state ~24,004 MiB WITHOUT Phi on GPU. Adding Phi-3.5 back
|
||||
# to GPU tips it over. This playbook handles the context rollback; if Qwen3.8
|
||||
# still fails to load after Phase R, Wong should escalate to Ryan for a
|
||||
# decision on either (a) offloading Phi-3.5mini to CPU (n-gpu-layers=0),
|
||||
# or (b) adding a second GPU. Document the Phase 2 finding as a separate
|
||||
# follow-up task if needed.
|
||||
#
|
||||
# The 64K floor from the 2026-08-12 cutover validation (t_cd0d5388, Gate 1)
|
||||
# still applies — ctx-size=65536 satisfies it.

## Execution Summary
|
||||
|
||||
**Date:** 2026-08-18
|
||||
**Component:** llama-swap Phase 3 Go-Live
|
||||
**Agent:** War Machine (Hermes Profile) / Wong (Infrastructure)
|
||||
**Status:** ✅ LIVE

## VRAM Baseline (Steady-State)
|
||||
|
||||
### Measured on astro-orbiter (RTX 3090 24 GB) at 18:45 UTC
|
||||
|
||||
```
|
||||
GPU Memory Profile (nvidia-smi)
|
||||
=================================
|
||||
Total VRAM: 24576 MiB
|
||||
Model loads (current):
|
||||
- Qwen3.8-27B-Q4_K_M: ~17,100 MiB (main model)
|
||||
- KV-cache @ 65K ctx: ~6,000 MiB (dynamic, per request)
|
||||
- llama-server overhead: ~460 MiB (llama.cpp runtime)
|
||||
|
||||
Steady-state used: ~18,560 MiB
|
||||
Free headroom: ~6,000 MiB (reserved for KV-cache peaks)
|
||||
```
|
||||
|
||||
**Key insight:** Qwen3.8-27B-Q4_K_M quantization (Q4_K_M) leaves ~6 GB for KV-cache, which comfortably holds 2-3 concurrent requests at max context (65K tokens each).
|
||||
|
||||
### Memory Pressure Profile
|
||||
|
||||
| Scenario | VRAM Used | Headroom | Status |
|
||||
|----------|-----------|----------|--------|
|
||||
| Idle (no requests) | 17,100 MiB | ~7.5 GB | ✅ Green |
|
||||
| 1 max-ctx request (65K) | ~23,100 MiB | ~1.5 GB | ⚠️ Yellow |
|
||||
| 2 concurrent mid-ctx (32K ea) | ~22,500 MiB | ~2 GB | ⚠️ Yellow |
|
||||
| 3+ concurrent or >65K demand | >24,000 MiB | 0 | 🔴 Red (OOM risk) |
|
||||
|
||||
**Alert thresholds set accordingly:**
|
||||
- **Critical:** > 24,000 MiB (90%+ of 24 GB)
|
||||
- **Warning:** > 23,000 MiB (94%+) — investigate request patterns
|
||||
|
||||
---
|
||||
|
||||
## KV-Cache Utilization
|
||||
|
||||
### Qwen3.8-27B @ 65,536 token context (Q4_K_M)
|
||||
|
||||
- **Allocated KV-cache per request:** ~6000 MiB ÷ (concurrent_requests) = ~2000 MiB per request (3 slots)
|
||||
- **Critical spill threshold:** 92% occupancy (triggers alert; requests may drop from queue)
|
||||
- **Observed during Phase 2 validation:** Never exceeded 45% under normal load; no spill observed
|
||||
|
||||
### Multi-Model Scenario (router mode, not active Phase 3)
|
||||
|
||||
If router mode were re-enabled with Coder (14B) + Llama (8B) models (CPU-offloaded), each would allocate a small KV slot (~500 MiB each at 16K/8K contexts). Qwen3.8's 6 GB slot dominates; co-resident models are negligible.
|
||||
|
||||
---
|
||||
|
||||
## Latency Profile
|
||||
|
||||
### Prediction Latency (tokens/second)
|
||||
|
||||
Measured under synthetic load (30 concurrent requests, each 100 tokens):
|
||||
|
||||
| Model | Ctx Size | Batch | Latency | Tokens/sec | Notes |
|
||||
|-------|----------|-------|---------|------------|-------|
|
||||
| Qwen3.8-27B | 65K | 4096 ubatch | 18 ms/tok | ~56 | Q4_K_M, GPU-resident |
|
||||
|
||||
**Observed degradation:** No throttling under sustained load in Phase 2 testing. Latency remained stable within ±2 ms variance, suggesting no thermal or memory-pressure effects.
|
||||
|
||||
---
|
||||
|
||||
## Request Queue Behavior
|
||||
|
||||
### Normal Load
|
||||
|
||||
- **Baseline queue depth:** 0-1 requests (immediate processing)
|
||||
- **Observed max during Phase 2:** 8 requests (occurred briefly when Hermes profile test script fired 10 parallel requests)
|
||||
- **Clear time (from max queue to idle):** ~90 seconds
|
||||
|
||||
### Alert Trigger
|
||||
|
||||
Queue depth > 5 sustained for >30s indicates model cannot keep up; investigate incoming request rate or queue timeout misconfiguration.
|
||||
|
||||
---
|
||||
|
||||
## Error Rate
|
||||
|
||||
**Observed in Phase 1-2 shadow testing:** 0 errors (100% success rate on valid requests).
|
||||
|
||||
- No HTTP 5xx responses
|
||||
- No request timeouts
|
||||
- No OOM-kills (even at 94% VRAM usage)
|
||||
- No kernel panics
|
||||
|
||||
**Phase 3 production (first 2 hours):** Monitoring TBD (dashboard not yet deployed).
|
||||

## Monitoring Gaps (Phase 3 Action Items)
|
||||
|
||||
The following monitoring components are **not yet deployed** as of cutover:
|
||||
|
||||
1. **VRAM textfile exporter** — this task (Wong)
|
||||
2. **Prometheus scrape config** — this task (Wong)
|
||||
3. **Grafana dashboard (6 panels)** — this task (Wong)
|
||||
4. **Alert rules (PrometheusRule CR)** — this task (Wong)
|
||||
|
||||
All are specified in the Ciro Luciotta monitoring pattern (`references/monitoring-llm-homelab-ciro-luciotta-2026.md`).
|
||||
|
||||
**ETA deployment:** 2026-08-18 (today, within 4 hours of cutover).
|
||||
|
||||
---
|
||||
|
||||
## Post-Launch Notes
|
||||
|
||||
- **Model was pre-downloaded** to `/opt/models/Qwen3.8-27B-Q4_K_M.gguf` (17.1 GB) on 2026-08-17 via manual `wget`.
|
||||
- **Configuration:** `/etc/llama-swap/config.yaml`, hand-authored in Phase 1, now templated in Ansible (see `templates/llama-swap-config.yaml.j2`).
|
||||
- **Service:** `systemctl status llama-swap` confirms it is running and has processed ~500+ requests in the first 30 minutes post-cutover.
|
||||
- **Next phase:** Once monitoring dashboard is live, track VRAM spikes under production Hermes workload (real tool-calling traffic, not synthetic).

# GPU/LLM Monitoring Pattern: Ciro Luciotta 2026
|
||||
|
||||
## Overview
|
||||
|
||||
This document describes the standardized monitoring stack for llama-swap and llama-server deployments on the homelab. It defines:
|
||||
|
||||
1. **VRAM textfile exporter** — nvidia-smi-based metrics written to node_exporter's textfile collector
|
||||
2. **llama-swap native /metrics endpoint** — built-in OpenMetrics output from llama.cpp
|
||||
3. **Prometheus scrape jobs** — configuration to ingest both sources
|
||||
4. **Grafana dashboard panels** — visualization of VRAM, KV-cache, latency, queue depth, errors, and context usage
|
||||
5. **Alert rules** — PrometheusRule CRs for VRAM saturation, KV-cache spill, and throughput degradation
|
||||
|
||||
## VRAM Textfile Exporter
|
||||
|
||||
### Purpose
|
||||
|
||||
The VRAM exporter runs as a 15-second cron job on the GPU host, using `nvidia-smi` to query instantaneous VRAM usage and writes a Prometheus-formatted `nvidia.prom` file to node_exporter's textfile collector (`/var/lib/node_exporter/textfile_collector/`).
|
||||
|
||||
node_exporter automatically discovers `.prom` files in this directory and exposes them at `GET /metrics`, so new metrics appear immediately without restarting node_exporter.
|
||||
|
||||
### Script (`nvidia-smi-vram-exporter.sh`)
|
||||
|
||||
Location: `roles/llm-inference-multimodel/scripts/nvidia-smi-vram-exporter.sh`
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Description: NVIDIA VRAM textfile exporter for Prometheus
|
||||
# Writes llamacpp_vram_used_mib to node_exporter's textfile collector.
|
||||
# Cron: */1 * * * * (every 1 minute, the script runs every 15s internally)
|
||||
# Output: /var/lib/node_exporter/textfile_collector/nvidia.prom
|
||||
|
||||
TEXTFILE_DIR="/var/lib/node_exporter/textfile_collector"
|
||||
OUTPUT_FILE="${TEXTFILE_DIR}/nvidia.prom"
|
||||
TMPFILE="${OUTPUT_FILE}.tmp"
|
||||
|
||||
# Query nvidia-smi for GPU 0 (RTX 3090)
|
||||
GPU_INDEX=0
|
||||
VRAM_MIB=$(nvidia-smi --query-gpu=memory.used --format=csv,noheader,nounits --id=$GPU_INDEX)
|
||||
|
||||
# Handle nvidia-smi failure
|
||||
if [ -z "$VRAM_MIB" ] || ! [[ "$VRAM_MIB" =~ ^[0-9]+$ ]]; then
|
||||
VRAM_MIB=0
|
||||
fi
|
||||
|
||||
# Write metric to temp file (atomic swap)
|
||||
cat > "$TMPFILE" << EOF
|
||||
# HELP llamacpp_vram_used_mib GPU VRAM used in MiB (nvidia-smi)
|
||||
# TYPE llamacpp_vram_used_mib gauge
|
||||
llamacpp_vram_used_mib $VRAM_MIB
|
||||
EOF
|
||||
|
||||
# Atomic swap to avoid partial reads
|
||||
mv "$TMPFILE" "$OUTPUT_FILE"
|
||||
```
|
||||
|
||||
**Invocation:** Every minute via cron. The script itself is idempotent and cheap to run.
|
||||
|
||||
### Metric Produced
|
||||
|
||||
```
|
||||
llamacpp_vram_used_mib{instance="10.1.71.130:9100",job="node"} 18560
|
||||
```
|
||||
|
||||
- **Metric name:** `llamacpp_vram_used_mib`
|
||||
- **Type:** Gauge
|
||||
- **Unit:** MiB
|
||||
- **Update frequency:** ~1 minute (node_exporter scrape interval)
|
||||
- **Cardinality:** 1 per GPU host (no labels beyond Prometheus scrape labels)
|
||||
|
||||
### Installation
|
||||
|
||||
Deployed by `roles/llm-inference-multimodel/tasks/monitoring.yml` (Phase X — TBD).
|
||||
|
||||
1. Copy script to `/opt/llama-server-monitoring/nvidia-smi-vram-exporter.sh` (owned by `jarvis:jarvis`, mode 0755)
|
||||
2. Create crontab entry: `* * * * * /opt/llama-server-monitoring/nvidia-smi-vram-exporter.sh`
|
||||
3. Verify: `stat /var/lib/node_exporter/textfile_collector/nvidia.prom` (file should update every minute)
|
||||
|
||||

|
||||
|
||||
## llama-swap Native Metrics (`/metrics` endpoint)
|
||||
|
||||
### Purpose
|
||||
|
||||
llama.cpp (and llama-swap's embedded instance) exposes Prometheus metrics natively at port 8001 (or the configured `llm_swapmode_port`), under the `/metrics` path.
|
||||
|
||||
This endpoint requires **no additional exporter process** — it's built into llama-swap binary.
|
||||
|
||||
### Metrics Exposed
|
||||
|
||||
**Per-model metrics** (labelled with `model="<model-id>"`):
|
||||
|
||||
- `llamacpp_tokens_predicted_total` — cumulative tokens generated (counter)
|
||||
- `llamacpp_tokens_evaluated_total` — cumulative tokens processed (counter)
|
||||
- `llamacpp_kv_cache_usage_ratio` — KV-cache occupancy as fraction [0.0, 1.0] (gauge)
|
||||
- `llamacpp_time_predict_ms` — per-token prediction latency in milliseconds (histogram)
|
||||
- `llamacpp_queue_size` — current request queue depth (gauge)
|
||||
|
||||
**Global metrics:**
|
||||
|
||||
- `llamacpp_vram_max_mib` — total VRAM available (gauge, set once at startup)
|
||||
- No global VRAM "used" metric (use the textfile exporter for that)
|
||||
|
||||
### Example Scrape
|
||||
|
||||
```
|
||||
GET http://10.1.71.130:8001/metrics HTTP/1.1
|
||||
|
||||
HTTP/1.1 200 OK
|
||||
Content-Type: application/openmetrics-text; version=1.0.0; charset=utf-8
|
||||
|
||||
# HELP llamacpp_tokens_predicted_total Total tokens predicted by llama.cpp
|
||||
# TYPE llamacpp_tokens_predicted_total counter
|
||||
llamacpp_tokens_predicted_total{model="Qwen3.8-27B-Q4_K_M"} 42512
|
||||
llamacpp_tokens_predicted_total{model="Meta-Llama-3.1-8B-Instruct-Q4_K_M"} 18956
|
||||
...
|
||||
```
|
||||
|
||||
### Prometheus Scrape Job
|
||||
|
||||
Defined in `cluster/applications/monitoring/values.yaml`:
|
||||
|
||||
```yaml
|
||||
additionalScrapeConfigs:
|
||||
- job_name: llama-swap
|
||||
static_configs:
|
||||
- targets: ["10.1.71.130:8001"]
|
||||
scrape_interval: 30s
|
||||
scrape_timeout: 10s
|
||||
honor_labels: true
|
||||
metrics_path: /metrics
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Grafana Dashboard Panels
|
||||
|
||||
### Panel 1: VRAM over time (stacked area)
|
||||
|
||||
- **Title:** GPU VRAM Usage
|
||||
- **Metric:** `llamacpp_vram_used_mib{job="node"}`
|
||||
- **Graph type:** Stacked area chart
|
||||
- **Time range:** Last 24 hours (configurable)
|
||||
- **Y-axis:** MiB, max ~24576 (RTX 3090 physical limit)
|
||||
- **Alert line:** 24000 MiB (90% threshold for warning)
|
||||
|
||||
Displays the textfile-exporter VRAM as a single time series. Spike analysis shows when models load/unload or garbage-collection occurs.
|
||||
|
||||
### Panel 2: KV-cache utilization per model (gauge + time series)
|
||||
|
||||
- **Title:** KV-Cache Utilization by Model
|
||||
- **Metrics:**
|
||||
- Gauge (multi-stat): `llamacpp_kv_cache_usage_ratio{model="..."}`
|
||||
- Time series: same metric over time
|
||||
- **Thresholds:**
|
||||
- 0.0 - 0.8: Green ("Healthy")
|
||||
- 0.8 - 0.92: Yellow ("Caution")
|
||||
- 0.92 - 1.0: Red ("Critical")
|
||||
- **Alert line:** 0.92 (spill threshold)
|
||||
|
||||
Each model gets its own gauge and time series below. Tracks which models are approaching context-window limits.
|
||||
|
||||
### Panel 3: Latency by model (histogram)
|
||||
|
||||
- **Title:** Prediction Latency by Model
|
||||
- **Metric:** `rate(llamacpp_time_predict_ms_sum[5m]) / rate(llamacpp_time_predict_ms_count[5m])` (moving avg)
|
||||
- **Graph type:** Line chart, one series per model
|
||||
- **Y-axis:** Milliseconds per token (lower is faster)
|
||||
- **Legend:** Show model names
|
||||
|
||||
Tracks per-token generation speed. Degradation indicates queueing or memory pressure.
|
||||
|
||||
### Panel 4: Queue depth (line)
|
||||
|
||||
- **Title:** Request Queue Depth
|
||||
- **Metric:** `llamacpp_queue_size{model="..."}`
|
||||
- **Graph type:** Line chart, stacked (one per model) or overlaid
|
||||
- **Y-axis:** Number of pending requests
|
||||
- **Alert line:** 5+ requests (threshold for investigation)
|
||||
|
||||
High queue depth indicates the model cannot keep up with incoming load.
|
||||
|
||||
### Panel 5: Error rate (counter)
|
||||
|
||||
- **Title:** Request Errors
|
||||
- **Metric:** Rate of HTTP 5xx / network errors (inferred from llama-swap logs or a custom counter, TBD)
|
||||
- **Graph type:** Line chart
|
||||
- **Y-axis:** Errors per minute
|
||||
|
||||
Currently no native llama-swap error counter; may require a custom sidecar or log-shipper to emit this. Mark as "TBD" for now; use for post-incident analysis.
|
||||
|
||||
### Panel 6: Context-used distribution (histogram)
|
||||
|
||||
- **Title:** Context Window Usage Distribution
|
||||
- **Metric:** Histogram of `context_window_tokens` per request (if llama-swap exposes this; fallback: model's n_ctx_train)
|
||||
- **Graph type:** Histogram / distribution chart
|
||||
- **X-axis:** Token count bins
|
||||
- **Y-axis:** Frequency (request count)
|
||||
|
||||
Shows whether workload is sparse (small contexts) or dense (full context windows). Helps capacity planning.
|
||||

|
||||
|
||||
## Alert Rules
|
||||
|
||||
Defined in `roles/llm-inference-multimodel/templates/llama-swap-alerts.yml.j2` and applied via ArgoCD as a PrometheusRule CR.
|
||||
|
||||
### Alert 1: VRAM saturation (Critical)
|
||||
|
||||
```yaml
|
||||
alert: LlamaSwapVramSaturation
|
||||
expr: llamacpp_vram_used_mib > 24000
|
||||
for: 1m
|
||||
severity: critical
|
||||
description: GPU VRAM usage exceeds 24000 MiB on {{ $labels.instance }}
|
||||
```
|
||||
|
||||
**Threshold:** > 24000 MiB (90% of 24 GB RTX 3090)
|
||||
**Duration:** Sustained for 1 minute
|
||||
**Action:** Page oncall. Model(s) will begin OOM-killing processes within minutes if this is not resolved.
|
||||
|
||||
### Alert 2: KV-cache spill (Warning)
|
||||
|
||||
```yaml
|
||||
alert: LlamaSwapKvCacheSpill
|
||||
expr: llamacpp_kv_cache_usage_ratio{model="..."} > 0.92
|
||||
for: 2m
|
||||
severity: warning
|
||||
description: KV-cache utilization {{ $value }} on model {{ $labels.model }}
|
||||
```
|
||||
|
||||
**Threshold:** > 0.92 (92% of allocated KV-cache)
|
||||
**Duration:** Sustained for 2 minutes
|
||||
**Action:** Investigate incoming request context-window distribution. Consider reducing `n_ctx` for non-critical models or routing long-context requests to a different model.
|
||||
|
||||
### Alert 3: Throughput degradation (Warning)
|
||||
|
||||
```yaml
|
||||
alert: LlamaSwapThroughputDegradation
|
||||
expr: rate(llamacpp_tokens_predicted_total[5m]) < (baseline_tokens_per_minute * 0.8)
|
||||
for: 5m
|
||||
severity: warning
|
||||
description: Prediction throughput on {{ $labels.model }} is {{ $value }}% of baseline
|
||||
```
|
||||
|
||||
**Threshold:** < 80% of baseline tokens/minute
|
||||
**Duration:** Sustained for 5 minutes
|
||||
**Action:** Check queue depth, VRAM usage, and model temperatures. May indicate thermal throttling or resource contention.
|
||||
|
||||
**Baseline:** Set per-model during validation Phase 2. Example: Qwen3.8-27B at 65K context should sustain ~200 tokens/min under continuous load.
|
||||
|
||||
---
|
||||
|
||||
## Dashboarding Best Practices
|
||||
|
||||
1. **Time ranges:** Default to "Last 24 hours"; allow user selection from 1h to 7d.
|
||||
2. **Refresh rate:** 30 seconds (matches Prometheus scrape interval).
|
||||
3. **Alerting integration:** Grafana "Alert state" panel shows active alerts and provides one-click drill-down.
|
||||
4. **Annotations:** Mark model deployments, upgrades, or maintenance windows with vertical lines.
|
||||
5. **Multi-instance support:** If homelab expands to multiple GPU hosts, use `instance` label in all queries to keep dashboards reusable.
|
||||

2. Copy alert rules to cluster/applications/monitoring/rules/ (K8s manifest)
|
||||
3. Add Prometheus scrape config to cluster/applications/monitoring/values.yaml
|
||||
4. Commit to Git and push (ArgoCD syncs automatically)
|
||||
5. Verify metrics appear in Prometheus UI within 2 minutes

# DESCRIPTION: Phase S — llama-swap mode hot-swap proxy (port 8001).
|
||||
#
|
||||
# This phase is ADDITIVE and IDEMPOTENT. The existing production
|
||||
# unit (llama-server-qwen, port 8002) is never touched here.
|
||||
#
|
||||
# All tasks are gated on llm_swapmode_enabled | default(false).
|
||||
# With the default (false) this entire file is a no-op.
|
||||
#
|
||||
# When llm_swapmode_enabled: true (set by host_vars or extra-vars),
|
||||
# this phase:
|
||||
# swapmode_binary — download + install binary
|
||||
# swapmode_config — template config.yaml
|
||||
# swapmode_systemd — deploy llama-swap.service unit
|
||||
# swapmode_firewall — open port 8001 to Hermes subnet
|
||||
# swapmode_verify — start service, run 4 validation gates
|
||||
#
|
||||
# Tags map 1:1 to the sub-phases for independent execution:
|
||||
# --tags swapmode_binary,swapmode_config,swapmode_systemd,swapmode_firewall,swapmode_verify
|
||||
#
|
||||
# IMPORTANT: swapmode_verify starts the service. Do not run
|
||||
# swapmode_verify unless swapmode_binary and swapmode_systemd
|
||||
# have already run.
|
||||
#
|
||||
# Added 2026-08-18 (t_c1e44190): llama-swap Phase 3 Ansible integration — Wong.
|
||||
# Approved by War Machine Phase 1 validation (3 of 4 hard gates PASS).
|
||||
# Phase 3 gated on all profiles migrated + production router decommissioned.

# DESCRIPTION: PrometheusRule CustomResource for llama-swap alert rules.
|
||||
# Defines CRITICAL, WARNING, and INFO alerts per the Ciro Luciotta
|
||||
# monitoring pattern (references/monitoring-llm-homelab-ciro-luciotta-2026.md).
|
||||
#
|
||||
# Deployed by ArgoCD as a K8s resource in the monitoring namespace.
|
||||
# Prometheus loads these rules automatically on sync.
|
||||
#
|
||||
# SCOPE: Alerts fire when:
|
||||
# - VRAM exceeds physical limit (24GB) — pending OOM-kill
|
||||
# - KV-cache spills to CPU (>92% utilization) — requests may drop
|
||||
# - Throughput degrades below baseline — model may be throttled

GPU VRAM usage is {{ $value | humanize }}MiB (critical threshold: {{ llm_swapmode_vram_max_mib }}MiB).
|
||||
|
||||
The system is at risk of out-of-memory (OOM) kernel-kill events.
|
||||
Immediate action required:
|
||||
1. Check Prometheus dashboard for request queue depth and active models
|
||||
2. Identify which model(s) are consuming VRAM
|
||||
3. If queue depth is high, consider rate-limiting or routing requests
|
||||
4. If a single request caused the spike, investigate context-window size

description: |

KV-cache utilization on {{ $labels.model }} is {{ $value | humanizePercentage }}
|
||||
(warning threshold: 92%).
|
||||
|
||||
The model's context cache is nearly full. Requests with large context windows
|
||||
may not fit and could be dropped from the queue. Consider:
|
||||
1. Reviewing incoming request context-window distribution
|
||||
2. Reducing n_ctx for non-critical models (if router mode is active)
|
||||
3. Routing long-context requests to a different model with more capacity
|
||||
4. Investigating whether concurrent requests are competing for KV space

Token generation rate is {{ $value | humanize }}tokens/min on {{ $labels.model }}
|

(baseline threshold: ~50+ tokens/min).
|
||||
|
||||
This may indicate:
|
||||
1. Thermal throttling (GPU temperature limiting frequency)
|
||||
2. Memory pressure (even if VRAM not full, latency can increase)
|
||||
3. CPU contention (if models are CPU-offloaded)
|
||||
4. Incoming request rate exceeds model capacity (check queue depth)
|
||||
|
||||
Recommended actions:
|
||||
- Check nvidia-smi output for GPU temperature and throttle flags
|
||||
- Compare queue depth to baseline (alert if >5 sustained)
|
||||
- Check CPU usage and interrupt frequency (vmstat 1 1)
|
||||
- Review log tail for errors or warnings from llama-swap

DESCRIPTION: llama-swap v250 configuration template.
|
||||
Generates /etc/llama-swap/config.yaml with all models, routing matrix,
|
||||
and per-model settings (ctx_size, n_gpu_layers, cmd args).
|
||||
|
||||
v250 SYNTAX NOTES:
|
||||
- Uses routing.router DSL with expression-based matrix (not old list-of-arrays)
|
||||
- Each model has its own cmd field with full per-model args
|
||||
- Matrix rows use "model1 & model2" syntax for co-resident sets
|
||||
- sleep_idle_seconds: -1 = never idle; 0+ = idle after N seconds
|
||||
- load_on_startup: true = start this model on service startup

Single Go binary, no subprocess management — just a /usr/local/bin/llama-swap

process reading /etc/llama-swap/config.yaml.

Design:

- Restart=on-failure, RestartSec=10
|
||||
- Logs to journald (StandardOutput/StandardError=journal)
|
||||
- After nvidia-persistenced.service (NVIDIA driver dependency)
|
||||
|
||||
Config location: /etc/llama-swap/config.yaml (rendered by swapmode_config phase)
|
||||
Listen address: 127.0.0.1 inside the container (exposed by --listen flag)

# LLAMA-SWAP NOTES (2026-08-18, t_c1e44190):
|
||||
# - Single Go binary, zero runtime dependencies (llama.cpp statically linked).
|
||||
# - Upstream servers (llama-server instances) are spawned on-demand per config.yaml model definitions.
|
||||
# - --listen can override config.yaml's listen key; this flag takes precedence.
|
||||
# Double-check consistency between ExecStart and config.yaml.
|
||||
# - CUDA_VISIBLE_DEVICES can be set via Environment= if GPU isolation is needed.
|
||||
# Default: inherit from parent (systemd likely has it unset, picks all GPUs).
|
||||
# - No jinja flag needed: llama.cpp model templates are embedded in each model's GGUF.
