I have a question related to the RRD graphs. Well, two questions.
1: If I see that my pfSense firewall is using 80% CPU, and it's all in interrupts (by looking at the RRD graphs), does that mean that all CPUs are adding up to 80% total, or is it just one CPU that is working at 80%?
2: My switch on the LAN side is showing that 4Gb/s are moving outbound through the firewall. I can see this via a local cacti installation (that also uses rrdtool to make it's graphs) I have that watches the bandwidth on the switchports. But when I look at the RRD graphs on pfSense, I see mostly empty space with a few spots where 1Gb/s is showing. But it's mostly blank. Can I assume that the pfSense RRD configuration has a 1Gb/s max on the bandwidth graphs? And when it goes above 1Gb/s, it just stops plotting the datapoints?
Thanks for any info!
