CPU Usage and RRD question



  • Hi Folks,

    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 port.  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!
