# 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` file
|
|
- `soft_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
|
