Inverted CPU graphs. Same node, different interface.

Hey Henry,

So this is an interesting one. I have a Docker swarm setup with separate management and data interfaces, this means that each of my Docker nodes has 2 network adapters.

All of my nodes has an agent running on it. For testing purposes I added the IP of both interfaces to Beszel, All of the logging seems to be the same for both interfaces, as expected, since it's the same machine. However, the CPU graphs seem to be inverted:

Are these using the same agent instance?

Stats like RAM and disk usage will be the same because those are just moment-in-time snapshots. But for CPU we check the total usage since the last query and divide it by the time between the checks. That gives us the average usage over the intervening time.

If you have multiple systems hooked up to the same agent instance, things can go wonky because different systems are resetting the time periods. And you may get some errors related to memory safety.

If you want multiple users to have access to the same system, share it through PocketBase rather than recreating it.

Try running running a second agent on a different port and setting the other system to use that agent instead. Then both should match very closely.

Closing but I'll reopen if you still have questions about this.
