Many of the examples provided within documentation are using a single dash for the command line arguments, but the telegraf executable explicitly has two dashes. There are also some inconsistencies with the ordering of the command line argument examples. I've ordered them so that the examples will show: config, config-directory, input-filter, test

# 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
|
|
