0G Monitoring Service

This is to monitor all 0G services, including blockchain fullnodes, storage nodes and some other infrastructures.

• Blockchain
  • Fullnode RPC availability via eth_blockNumber.
  • Whether block height fall behind, e.g. 30 blocks behind the highest block height.
  • Whether blockchain height stops growing.

Configuration

There are two files to configure monitoring parameters:

• config.yaml: change any default configurations and uncomment out.
• .env: recommended, overwrite configurations via environment variables prefixed with ZG_MONITOR, for example:

# Log Configurations
export ZG_MONITOR_LOG_ALERTHOOK_CHANNELS="dingtalk,telegram"


# Alert Configurations
export ZG_MONITOR_ALERT_CUSTOMTAGS="testnet"
export ZG_MONITOR_ALERT_CHANNELS_DINGTALK_PLATFORM="dingtalk"
export ZG_MONITOR_ALERT_CHANNELS_DINGTALK_WEBHOOK="${dingtalk_webhook_url}"
export ZG_MONITOR_ALERT_CHANNELS_DINGTALK_SECRET="${dingtalk_secret}"
export ZG_MONITOR_ALERT_CHANNELS_TELEGRAM_PLATFORM="telegram"
export ZG_MONITOR_ALERT_CHANNELS_TELEGRAM_APITOKEN="${telegram_api_token}"
export ZG_MONITOR_ALERT_CHANNELS_TELEGRAM_CHATID="${telegram_chat_id}"

# Metrics configurations
export ZG_MONITOR_METRICS_ENABLED=true
export ZG_MONITOR_METRICS_INFLUXDB_HOST="http://127.0.0.1:8086"
export ZG_MONITOR_METRICS_INFLUXDB_DB="0gmonitor"
export ZG_MONITOR_METRICS_INFLUXDB_USERNAME="admin"
export ZG_MONITOR_METRICS_INFLUXDB_PASSWORD="123456"


# Blockchain Monitoring Configurations
export ZG_MONITOR_BLOCKCHAIN_NODES_NODE0="http://ip0:8545"
export ZG_MONITOR_BLOCKCHAIN_NODES_NODE1="http://ip1:8545"
export ZG_MONITOR_BLOCKCHAIN_NODES_NODE2="http://ip2:8545"

export ZG_MONITOR_BLOCKCHAIN_VALIDATORS_VAL0="kavavalcons17metfygkc7aezdrx6aucnpsh7ggh4lrhrawj66"
export ZG_MONITOR_BLOCKCHAIN_VALIDATORS_VAL1="kavavalcons17metfygkc7aezdrx6aucnpsh7ggh4lrhrawj67"
export ZG_MONITOR_BLOCKCHAIN_VALIDATORS_VAL2="kavavalcons17metfygkc7aezdrx6aucnpsh7ggh4lrhrawj68"

Run

Before monitoring service launched, do not forget to load the .env file if any.

# Load configurations on prod machine.
source .env

# Start monitoring service.
./0g-monitor

Utilities

There are some helpful scripts as following:

• ./scripts/start.sh: start monitoring service if not launched yet.
• ./scripts/stop.sh: stop monitoring service if launched.
• ./scripts/test.sh: test monitoring service at local.
