Agent Configuration (SubscriptionConfig)

All Parameters

from omnidaemon import AgentConfig, SubscriptionConfig

await sdk.register_agent(
    agent_config=AgentConfig(
        # REQUIRED
        topic="file.uploaded",
        callback=process_file,

        # OPTIONAL
        name="file-processor",
        description="Processes uploaded files",
        tools=["file_reader", "image_processor"],

        config=SubscriptionConfig(
            # Consumer settings
            consumer_count=3,              # Number of parallel consumers

            # Retry settings
            reclaim_idle_ms=300000,        # 5 minutes
            dlq_retry_limit=3,             # Max retries before DLQ

            # Advanced (rarely changed)
            group_name=None,               # Auto-generated if None
            consumer_name=None,            # Auto-generated if None
        ),
    )
)

Parameter Details

`consumer_count` (Optional)

What: Number of parallel consumers for this agent Default: 1 Range: 1 to 100+ When to increase:

✅ High message volume
✅ Fast processing (< 1 second per message)
✅ Want higher throughput

When to keep low:

✅ Low message volume
✅ Slow processing (> 10 seconds per message)
✅ External rate limits

Examples:

# Low traffic (default)
consumer_count=1

# Medium traffic
consumer_count=3

# High traffic
consumer_count=10

# Very high traffic
consumer_count=50

Effect:

consumer_count=1  → 1 message processed at a time
consumer_count=3  → 3 messages processed in parallel
consumer_count=10 → 10 messages processed in parallel

`reclaim_idle_ms` (Optional)

What: How long (milliseconds) before reclaiming a stuck message Default: 180000 (3 minutes) Range: 1000 (1 second) to 3600000 (1 hour) How it works:

Message delivered to consumer
If not acknowledged within reclaim_idle_ms
Message reclaimed by another consumer

When to decrease:

✅ Fast tasks (< 1 minute)
✅ Want quick failure recovery
⚠️ Be careful not to reclaim in-progress tasks!

When to increase:

✅ Slow tasks (> 5 minutes)
✅ External API calls with delays
✅ Avoid premature reclaiming

Examples:

# Fast tasks (30 seconds)
reclaim_idle_ms=30000

# Medium tasks (5 minutes - default)
reclaim_idle_ms=300000

# Slow tasks (15 minutes)
reclaim_idle_ms=900000

# Very slow tasks (1 hour)
reclaim_idle_ms=3600000

Formula:

reclaim_idle_ms = (avg_processing_time × 2) + buffer

Example:
  avg_processing_time = 2 minutes (120s)
  reclaim_idle_ms = (120 × 2) + 60 = 300 seconds = 300000 ms

`dlq_retry_limit` (Optional)

What: Max retries before sending to Dead Letter Queue Default: 3 Range: 0 (no retries) to 10+ How it works:

Message fails processing
Retry #1
Retry #2
Retry #3
After dlq_retry_limit failures → DLQ

When to increase:

✅ Transient errors common (network issues, rate limits)
✅ External services flaky
✅ Safe to retry (idempotent operations)

When to decrease:

✅ Permanent errors (bad data)
✅ Not idempotent (risky to retry)
✅ Want faster DLQ detection

Examples:

# No retries (permanent errors)
dlq_retry_limit=0

# Few retries (default)
dlq_retry_limit=3

# More retries (transient errors)
dlq_retry_limit=10

# Many retries (very flaky services)
dlq_retry_limit=20

Total attempts:

dlq_retry_limit=3 → 1 initial + 3 retries = 4 total attempts

Backend-Specific Configuration

Redis Streams (Event Bus)

Default Configuration (in code):

class RedisStreamEventBus:
    def __init__(
        self,
        redis_url: str = "redis://localhost:6379",
        default_maxlen: int = 10_000,              # Max messages per stream
        reclaim_interval: int = 30,                 # Reclaim check interval (seconds)
        default_reclaim_idle_ms: int = 180_000,     # Message idle time (3 min)
        default_dlq_retry_limit: int = 3,           # Max retries
    ):

Tuning: default_maxlen (Stream trimming)

Default: 10,000 messages
Low traffic: 1,000
High traffic: 100,000+
Effect: Older messages trimmed automatically

reclaim_interval (How often to check for stuck messages)

Default: 30 seconds
Fast recovery: 10 seconds
Low overhead: 60 seconds
Effect: How quickly stuck messages are detected

Redis Storage

Configuration via environment:

STORAGE_BACKEND=redis
REDIS_URL=redis://localhost:6379
REDIS_KEY_PREFIX=omni

Redis Persistence (in redis.conf):

# AOF (Append-Only File) - Recommended for production
appendonly yes
appendfsync everysec  # fsync every second (balanced)

# RDB (Snapshot) - Optional backup
save 900 1      # After 900 sec if ≥1 key changed
save 300 10     # After 300 sec if ≥10 keys changed
save 60 10000   # After 60 sec if ≥10000 keys changed

Memory Management:

# Max memory (e.g., 2GB)
maxmemory 2gb

# Eviction policy (don't evict - fail writes instead)
maxmemory-policy noeviction

JSON Storage

Configuration:

STORAGE_BACKEND=json
JSON_STORAGE_DIR=.omnidaemon_data

File Permissions:

# Ensure directory is writable
chmod 755 .omnidaemon_data

# Ensure files are writable
chmod 644 .omnidaemon_data/*.json

Backup:

# Daily backup
0 2 * * * tar -czf /backups/omnidaemon_$(date +\%Y\%m\%d).tar.gz .omnidaemon_data

Performance Tuning

High Throughput (1000+ messages/second)

# Agent configuration
config=SubscriptionConfig(
    consumer_count=20,          # Many parallel consumers
    reclaim_idle_ms=60000,      # 1 minute (fast reclaim)
    dlq_retry_limit=2,          # Few retries (fail fast)
)

# Redis configuration
# default_maxlen=100_000      # Keep more messages
# reclaim_interval=10         # Check frequently

Infrastructure:

Use Redis with AOF fsync=everysec
SSD storage for Redis
Sufficient RAM (all data in memory)
Multiple agent runner instances

Low Latency (< 100ms per message)

# Agent configuration
config=SubscriptionConfig(
    consumer_count=5,           # Moderate parallelism
    reclaim_idle_ms=30000,      # 30 seconds
    dlq_retry_limit=1,          # Fail fast
)

# Optimize callback
async def fast_callback(message: dict):
    # Avoid:
    # - Heavy computation
    # - Blocking I/O
    # - External API calls

    # Use:
    # - In-memory operations
    # - Async I/O
    # - Caching
    pass

High Availability

# Multiple agent runners
# Terminal 1
python agent_runner.py

# Terminal 2
python agent_runner.py

# Terminal 3
python agent_runner.py

Redis Sentinel (automatic failover):

REDIS_URL=redis+sentinel://sentinel1:26379,sentinel2:26379/mymaster/0

Redis Cluster (horizontal scaling):

REDIS_URL=redis://node1:6379,node2:6379,node3:6379

Memory Optimization

# Reduce storage
# - Lower result TTL (faster expiration)
# - Trim metrics more aggressively
# - Clear old data regularly

# In agent callback
async def callback(message: dict):
    # Don't save result if not needed
    return None  # Result not saved

# Clear old data (cron)
0 2 * * * omnidaemon storage clear-results
0 3 * * * omnidaemon storage clear-metrics

Security Configuration

Redis Authentication

# Redis with password
REDIS_URL=redis://:strong_password_here@redis:6379

# Redis with username (Redis 6+)
REDIS_URL=redis://username:password@redis:6379

Redis TLS/SSL

# Enable TLS (note: rediss://)
REDIS_URL=rediss://redis:6380

# With password
REDIS_URL=rediss://:password@redis:6380

Redis server configuration (redis.conf):

# Enable TLS
tls-port 6380
tls-cert-file /path/to/redis.crt
tls-key-file /path/to/redis.key
tls-ca-cert-file /path/to/ca.crt

API Security

# In production, use reverse proxy (nginx) with:
# - HTTPS/TLS
# - Authentication (API keys, JWT)
# - Rate limiting
# - IP whitelisting

# Example nginx config
server {
    listen 443 ssl;
    server_name api.example.com;

    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;

    location / {
        proxy_pass http://127.0.0.1:8765;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Environment Variable Security

# Use secrets management (Kubernetes, AWS Secrets Manager, HashiCorp Vault)

# Don't commit .env to git
echo ".env" >> .gitignore

# Use read-only permissions
chmod 400 .env

# Or use environment variables directly (no .env file)
export REDIS_URL="redis://:password@redis:6379"
export STORAGE_BACKEND="redis"

Configuration Best Practices

1. Environment-Specific Configs

config/
├── .env.development
├── .env.staging
└── .env.production

# Load appropriate config
cp config/.env.production .env

2. Configuration Validation

# Validate on startup
from decouple import config

def validate_config():
    required = ["EVENT_BUS_TYPE", "STORAGE_BACKEND"]

    for var in required:
        try:
            value = config(var)
            if not value:
                raise ValueError(f"{var} is empty")
        except Exception as e:
            print(f"❌ Missing required config: {var}")
            raise SystemExit(1)

    print("✅ Configuration valid")

validate_config()

3. Configuration Documentation

# Create .env.example (no secrets)
cat > .env.example << 'EOF'
# Event Bus
EVENT_BUS_TYPE=redis_stream
REDIS_URL=redis://localhost:6379

# Storage
STORAGE_BACKEND=redis

# API (optional)
OMNIDAEMON_API_ENABLED=false
OMNIDAEMON_API_PORT=8765

# Logging
LOG_LEVEL=INFO
EOF

4. Configuration Testing

# Test development config
cp .env.development .env
python agent_runner.py  # Should work

# Test staging config
cp .env.staging .env
python agent_runner.py  # Should work

# Test production config
cp .env.production .env
python agent_runner.py  # Should work

Troubleshooting Configuration

Redis Connection Issues

# Test Redis connection
redis-cli -u $REDIS_URL ping
# Should return: PONG

# Common issues:
# 1. Wrong URL
echo $REDIS_URL

# 2. Redis not running
sudo systemctl status redis

# 3. Firewall blocking
telnet redis-host 6379

# 4. Wrong password
redis-cli -u redis://:wrong_password@localhost:6379
# Error: NOAUTH Authentication required

Storage Issues

# JSON storage: Check directory exists and is writable
ls -la .omnidaemon_data
# Should show: drwxr-xr-x ... .omnidaemon_data

# Redis storage: Check connection
redis-cli -u $REDIS_URL PING

API Not Starting

# Check if enabled
echo $OMNIDAEMON_API_ENABLED
# Should be: true

# Check port not in use
lsof -i :8765
# Should be empty or show omnidaemon

# Test API
curl http://localhost:8765/health

Environment Variables Not Loading

# Debug: Print all config
from decouple import config

print(f"EVENT_BUS_TYPE: {config('EVENT_BUS_TYPE', default='NOT_SET')}")
print(f"STORAGE_BACKEND: {config('STORAGE_BACKEND', default='NOT_SET')}")
print(f"REDIS_URL: {config('REDIS_URL', default='NOT_SET')}")

# Ensure .env is in correct location
import os
print(f"Current directory: {os.getcwd()}")
print(f".env exists: {os.path.exists('.env')}")

Summary

Essential Environment Variables:

EVENT_BUS_TYPE=redis_stream
REDIS_URL=redis://localhost:6379
STORAGE_BACKEND=redis

Key SubscriptionConfig Parameters:

consumer_count=3           # Parallel consumers
reclaim_idle_ms=300000     # 5 minutes
dlq_retry_limit=3          # Max retries

Performance Tuning:

High throughput → Increase consumer_count
Low latency → Optimize callback, use caching
High availability → Multiple runners, Redis Sentinel/Cluster
Memory optimization → Clear old data, reduce TTL

Security:

Redis password/TLS
API behind reverse proxy with HTTPS
Secrets management (not .env)
Read-only permissions

Best Practices:

Environment-specific configs
Validate on startup
Document in .env.example
Test all environments
