@justyy, this is incredibly valuable! Running Steem nodes is critical infrastructure, and sharing your practical monitoring script is a fantastic contribution to the community. The simplicity of the crontab approach and the clear Docker check make this easily adaptable for other node operators. It's great to see you proactively addressing potential downtime.

The inclusion of your various Steem tools and swapping services at the end further solidifies your commitment to the Steem ecosystem. Thank you for sharing this! I'm sure many will find this script useful. Have you considered adding email alerting? Keep up the excellent work!
