Hetzner Robot Server Monitoring bulk mass adding

hetzner-robot-server-monitoring-bulk-mass-adding.js

/*
This script automatically adds many domains to the hetzner sysmon via robot console. It is preconfigured to create an http check on port 443 with ssl enabled and no auth.
Instructions:
1. Go to https://robot.hetzner.com/server
2. Open your server
3. Open "monitoring" tab
4. Click on "configured systems" to reveal the sysmon form (it should show a plus sign, checks list, etc)
5. Open devtools in your browser -> go to console
6. Make sure to select "System-Monitor" iframe context! the script won't run in the top page context
7. Modify "yourdomains" to add whatever domains you want
8. Run the script and it should add all the domains while correctly replacing csrf tokens each time
Make sure to reload the page or click the "reload" button near your server's ip after that to see added entries
