Zabbix plugin for /proc/interrupts monitoring
The same stats you can get from mpstat -I CPU

Script returns the number of interrupts per CPU on the x86 architecture from the /proc/interrupts file
For each IRQ and CPU pair, returns the number ot interrupts for this IRQ on this CPU
When run without parameters, script works in LLD mode and returns the list of macros:
{#CPUNUM} - kernel number. Column title from the /proc/interrupts file
{#CPUIDX} - kernel index. Number from {#CPUNUM}
{#IRQ} - number of interrupt. Value from the first column of the /proc/interrupts file
{#IRQLABEL}- type of interrupt and the name of the device that is located at that IRQ. Value from the last column of the /proc/interrupts file

The script creates stacked graphs for interrupts from the /proc/interrupts file
For each interrupt, a graph containing all cores is created
