The Addrbook is updated everyday. If you are not getting peers you can Stop your node, download and replace your addrbook.json with the steps below, and restart your node.

wget -O addrbook.json https://berafiles.blacknodes.net/berachain/addrbook.json --inet4-only
  mv addrbook.json $HOME/.berad/config/

Node Monitoring Guide

Install Monitoring Tools(Prometheus and Grafana using this script)

wget https://raw.githubusercontent.com/blacknodes/Scripts/main/install-monitoring-tools.sh
sudo chmod +x install-monitoring-tools.sh
./install-monitoring-tools.sh

Add Job "berachain-Node" in prometheus file

sed -i '/scrape_configs:/a \
  - job_name: "berachain-Node"\
    static_configs:\
      - targets: ["localhost:26660"]' /opt/prometheus/prometheus.yml

Set prometheus to true in config.toml file And Restart the node and prometheus

sed -i '/prometheus =/s/false/true/' /root/.berad/config/config.toml
sudo systemctl restart berad.service
sudo systemctl restart prometheus.service

Make Sure to enable port 3000

sudo ufw allow 3000

Go To http://yourip:3000

Add New DataSource Prometheus

Set Alert

Use this metric for alert(You can also use other metrics too, we recommend this one if you are a validator)

increase(cometbft_consensus_validator_last_signed_height[5m])

Set Threshold (is below 15) and change type from range to instant

Add Notification Channel (Here we will use telegram )

Use https://t.me/BotFather to create your notification bot and https://t.me/userinfobot to check your Telegram ID.

Add new Contact point, paste your bot api token and telegram id there

Now you'll receive an alert in your telegram bot whenever your node will stop or get out of the active set!

State-Sync(Currently Berachain Nodes dont support StateSync)

Use this StateSync method to synchronize your node within 10minutes

SNAP_RPC=https://berachain-testnet-rpc.blacknodes.net:443 && \
LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash) && \
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH
