二、日志管理方案
2.1 日志分级与格式
// MonkeyCode标准日志格式
{
"@timestamp": "2026-06-18T14:30:22.123Z",
"@version": "1",
"level": "INFO",
"logger_name": "monkeycode.core.engine",
"message": "Code completion request processed",
"thread_name": "completion-pool-3",
// 结构化字段
"request_id": "req_8f7a6b5c4d3e2f1a",
"user_id": "u_12345",
"session_id": "sess_abc123",
"tenant_id": "engineering-team",
// 业务上下文
"request_details": {
"language": "python",
"context_length": 2048,
"suggestions_count": 5,
"latency_ms": 45,
"model_version": "monkeycode-7b-v2.5",

},
// 环境信息
"host": "mc-node-03.internal",
"service": "monkeycode-core",
"version": "2.5.0",
"environment": "production"
}
2.2 ELK Stack集成配置
# Filebeat配置 - MonkeyCode日志采集
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/monkeycode/*.log
- /var/log/monkeycode/**/*.log
fields:
service: monkeycode
environment: production
fields_under_root: true
multiline:
pattern: '^\['
match: after
negate: true
# 敏感数据脱敏
processors:
- dissect:
tokenizer: '%{@timestamp} [%{level}] %{message}'
field: "message"
target_prefix: "parsed"
output.elasticsearch:
hosts: ["https://es-cluster.internal:9200"]
username: "${ES_USERNAME}"
password: "${ES_PASSWORD}"
ssl.certificate_authorities: ["/etc/filebeat/ca.crt"]
index: "monkeycode-%{+yyyy.MM.dd}"
三、分布式追踪
3.1 OpenTelemetry集成
# MonkeyCode OpenTelemetry 追踪配置
from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.resources import SERVICE_NAME, Resource
def setup_tracing():
"""初始化OpenTelemetry追踪"""
resource = Resource.create({
SERVICE_NAME: "monkeycode-core",
"service.version": "2.5.0",
"deployment.environment": "production"
})
provider = TracerProvider(resource=resource)
# 导出到Jaeger/Tempo
otlp_exporter = OTLPSpanExporter(
endpoint="otel-collector.internal:4317",
insecure=True
)
processor = BatchSpanProcessor(otlp_exporter)
provider.add_span_processor(processor)
trace.set_tracer_provider(provider)
return trace.get_tracer(__name__)
# 使用示例
tracer = setup_tracing()
@tracer.start_as_current_span("code_completion")
async def complete_code(request):
with tracer.start_as_span("context_analysis") as span:
span.set_attribute("language", request.language)
context = await analyze_context(request.code)
with tracer.start_as_span("model_inference") as span:
span.set_attribute("model", "monkeycode-7b")
result = await model.infer(context)
return result
3.2 关键追踪Span定义
| Span名称 | 层级 | 关键属性 | 典型耗时 |
|---|---|---|---|
http_request |
入口 | method, path, status | — |
auth_check |
认证 | user_id, role | <5ms |
rate_limit |
限流 | user_id, allowed | <1ms |
context_preprocess |
处理 | language, length | 5-20ms |
cache_lookup |
缓存 | hit/miss | 1-5ms |
model_inference |
推理 | model, tokens | 20-100ms |
post_process |
后处理 | filters_applied | 2-10ms |
audit_log |
审计 | request_id | <5ms |
四、告警规则体系
4.1 Prometheus告警规则
# monkeycode-alerts.yml
groups:
- name: monkeycode-critical
rules:
# 服务不可用
- alert: MonkeyCodeDown
expr: up{job="monkeycode"} == 0
for: 1m
labels:
severity: critical
annotations:
summary: "MonkeyCode服务不可用"
description: "实例 {{ $labels.instance }} 已下线超过1分钟"
# P99延迟过高
- alert: HighLatencyP99
expr: histogram_quantile(0.99,
rate(monkeycode_request_duration_seconds_bucket[5m])) > 0.5
for: 5m

# 错误率飙升
- alert: ErrorRateSpike
expr: |
(
sum(rate(monkeycode_request_errors_total[5m])) /
sum(rate(monkeycode_requests_total[5m]))
) > 0.05
for: 5m
labels:
severity: warning
annotations:

for: 15m
labels:
severity: info
annotations:

description: "当前命中率: {{ $value | humanizePercentage }}"
4.2 多渠道告警通知
# Alertmanager通知路由
route:
group_by: ['alertname', 'severity']
group_wait: 30s
group_interval: 5m
repeat_interval: 4h
receiver: 'default'
routes:
- match:
severity: critical
receiver: 'critical-alerts'
repeat_interval: 15m
- match:
severity: warning
receiver: 'warning-alerts'
receivers:
- name: 'critical-alerts'
webhook_configs:
- url: 'http://alertmanager-router/internal/dingtalk'
send_resolved: true
- name: 'warning-alerts'
webhook_configs:
- url: 'http://alertrouter/wechat/work'
send_resolved: true
五、Grafana仪表板设计
5.1 核心Dashboard面板
┌─────────────────────────────────────────────────────────────┐
│ MonkeyCode 运维总览 Dashboard │

5.2 关键Grafana查询示例
-- 1. 今日QPS趋势
sum(rate(monkeycode_requests_total[5m])) by (endpoint)
-- 2. 各语言补全采纳率
sum(rate(monkeycode_completion_accepted_total[1h])) by (language)
/ sum(rate(monkeycode_completion_total[1h])) by (language) * 100
-- 3. GPU利用率Top 5节点
topk(5, avg(nvidia_gpu_utilization_gpu{job="monkeycode"}) by (instance))
-- 4. Token消耗趋势（按团队）
sum(increase(monkeycode_tokens_consumed_total[1h])) by (tenant_id)
-- 5. 平均响应时间按端点
histogram_quantile(0.50,
sum(rate(monkeycode_request_duration_seconds_bucket[5m])) by (le, endpoint))
六、自动化运维
6.1 自动扩缩容策略
class AutoScaler:
"""MonkeyCode自动扩缩容"""
def check_and_scale(self):
metrics = self.collect_metrics()
# 规则1：CPU持续>80%，增加副本
if metrics.cpu_avg > 80 and metrics.duration_minutes > 10:
self.scale_up(replicas=+2)
# 规则2：队列积压>1000，紧急扩容
if metrics.queue_depth > 1000:
self.scale_up(replicas=+3, priority="urgent")
# 规则3：CPU<20%持续30分钟，缩容
if metrics.cpu_avg < 20 and metrics.duration_minutes > 30:
self.scale_down(replicas=-1)
# 规则4：错误率突增，触发回滚检查
if metrics.error_rate > 0.1:
self.trigger_rollback_check()
6.2 健康检查与自愈
#!/bin/bash
# health-check.sh - MonkeyCode健康检查脚本
ENDPOINT="http://localhost:8080/api/health"
TIMEOUT=10
MAX_RETRIES=3
check_health() {
response=$(curl -sf --max-time $TIMEOUT "$ENDPOINT" || echo "FAILED")
if [[ "$response" == *"healthy"* ]]; then
echo "✅ Health check passed"
return 0
else
echo "❌ Health check failed: $response"
return 1
fi
}
for i in $(seq 1 $MAX_RETRIES); do
if check_health; then
exit 0
fi
echo "Retry $i/$MAX_RETRIES in 5 seconds..."
sleep 5
done
# 所有重试失败，执行自愈
echo "🔄 Executing self-healing procedures..."
docker restart monkeycode-core
sleep 30
check_health && exit 1 # 仍失败，需要人工介入
exit 0
七、容量规划
7.1 资源预测模型
def predict_capacity(current_users, growth_rate, months_ahead=6):
"""
MonkeyCode容量预测模型
参数:
current_users: 当前活跃用户数
growth_rate: 月增长率（如0.05表示5%）
months_ahead: 预测月数
"""
predictions = []
for month in range(months_ahead + 1):
projected_users = current_users * ((1 + growth_rate) ** month)
# QPS估算：每人日均200次请求
qps = projected_users * 200 / 86400 * 3 # 峰值系数3x
# GPU需求：每100 QPS需1个A100等效算力
gpu_needed = max(1, math.ceil(qps / 100))
# 内存需求：基础8GB + 每用户50MB
memory_gb = 8 + (projected_users * 50 / 1024)
# 存储需求：审计日志增长
storage_tb = 0.5 + (projected_users * 0.001 * (month + 1))
predictions.append({
'month': month,
'users': int(projected_users),
'qps': round(qps, 1),
'gpu': gpu_needed,
'memory_gb': round(memory_gb, 1),
'storage_tb': round(storage_tb, 2)
})
return predictions
