Interrupts Input Plugin
The interrupts plugin gathers metrics about IRQs from /proc/interrupts
and /proc/softirqs
.
Configuration
[[inputs.interrupts]]
## To filter which IRQs to collect, make use of tagpass / tagdrop, i.e.
# [inputs.interrupts.tagdrop]
# irq = [ "NET_RX", "TASKLET" ]
Measurements
There are two measurements reported by this plugin.
interrupts
gathers metrics from the/proc/interrupts
filesoft_interrupts
gathers metrics from the/proc/softirqs
file
Fields
- CPUx: the amount of interrupts for the IRQ handled by that CPU
- total: total amount of interrupts for all CPUs
Tags
- irq: the IRQ
- type: the type of interrupt
- device: the name of the device that is located at that IRQ
Example Output
./telegraf --config ~/interrupts_config.conf --test
