This version is an updated version of itop written in perl. itop ==== Interrupts 'top-like' utility for Linux initial idea: http://et.redhat.com/~jmh/tools/xen/itop Forked it to make it support more CPUs (up to 24 tested) Modified by Mitch Williams <mitch.a.williams@intel.com> to enable filtering, user-specified timing interval, and to print the full interrupt name (instead of the interrupt type and a tiny bit of the name). == Usage itop [-a|-t|-f <string>|-i <interval>] -a : force display ALL CPUs (caution if you have many CPUs and a narrow screen) + TOTAL -t : DON'T display ALL CPUs, just the TOTAL Default: display ALL CPUs + TOTAL (unless CPUs > 8, then just display the TOTAL) -f <string>: only show interrupts that match on the specified string Default: display all interrupts -i <interval>: sample every <interval> seconds. Can be fractional. Default: sample and display every second. Note: specifying very short intervals without filters may cause display flickering. Example: $ itop - Displays all interrupts, updating once per second. $ itop -f eth0 - Only displays interrupts related to eth0, once per second $ itop -f ahci -n 5 - Only display interrupts owned by the ahci driver, every five seconds $ itop -f ixgbe -n 0.1 - Only display interrups owned by the ixgbe driver, ten times per second
