Scenario: How do I figure out and confirm that everything is working properly (eth 1 node in sync, eth 2 beacon chain in sync, eth 2 beacon node able to communicate with eth 1 node, etc etc.

The following steps align with our mainnet guide. You may need to adjust file names and directory locations where appropriate. The core concepts remain the same.
Execution client in sync
Example log output:INFO [12-06
Ports open
Confirm ports are reachable with an external port checker such as
Check execution client logs for errors
Use the command journalctl -fu eth1
Understand how to stop/start Execution client
sudo systemctl stop eth1
sudo systemctl start eth1
Understand how to update my Execution client
Reduce bandwidth usage
Execution client node redundancy
Installed latest stable release
Beacon chain client can connect to Execution client
Check for a response with the command:curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":67}' http://localhost:8545
You should receive a response similar to:
{"jsonrpc":"2.0","id":67,"result":"Geth/v1.9.24-stable-cc05b050/linux-amd64/go1.15.5"}
Beacon chain is sync'd to mainnet
Check beacon chain logs for errors
Use the command journalctl -fu beacon-chain
Ports open
Confirm ports are reachable with an external port checker such as
Understand how to stop/start beacon-chain
sudo systemctl stop beacon-chain
sudo systemctl start beacon-chain
Understand how to update my beacon chain
Join Discord
Verify keystores are properly imported
Check validator logs for errors
Use the command journalctl -fu validator
Verify attestations are working
Verified my mnemonic phrase can be restored.
Understand how to add more validators
Understand how to update my consensus client
Know how to stop/start validator
sudo systemctl stop validator
sudo systemctl start validator
Beacon-node redundancy
Secure the root account
Connect with SSH Keys Only
Harden SSH on a random port
Setup 2-FA for SSH (Optional)
Secure the Shared Memory
Setup a firewall
Setup port forwarding on my router
Setup intrusion-prevention monitoring
Whitelisted my local machine in the ufw firewall
Whitelisted my local machine in Fail2ban
Verify the listening ports
Enabled automatic OS patching
Setup chrony or other NTP time sync service
Setup Prometheus and Grafana Monitoring/Alerts/Dashboard
Understand how to handle a power outage
In case of power outage, you want your validator machine to restart as soon as power is available. In the BIOS settings, change the Restore on AC / Power Loss or After Power Loss setting to always on. Better yet, install an Uninterruptable Power Supply (UPS).
Understand how to migrate consensus clients
Understand how to voluntary exit
Used all available LVM disk space
Understand important directory locations
