Install it on other machine
1. Buy a VPS somewhere (I use vultr.com - virtual machine for 5 USD per month) and install CHR with a P1 license.
2. Make all your routers establish SSTP tunnels to the CHR.
3. Run the Dude on the CHR. It can monitor the machines and also devices inside the networks (if they have unique subnets).
It's fast, it uses the VPS provider's SSD drives (so write cycles to your flash memory won't destroy it) and it's quite cheap (you don't need to take care of the Dude machine running all the time, etc.)
