# Bond Input Plugin

The Bond input plugin collects network bond interface status for both the
network bond interface as well as slave interfaces.
The plugin collects these metrics from `/proc/net/bonding/*` files.

## Configuration

```toml
[[inputs.bond]]
  ## Sets 'proc' directory path
  ## If not specified, then default is /proc
  # host_proc = "/proc"

  ## By default, telegraf gather stats for all bond interfaces
  ## Setting interfaces will restrict the stats to the specified
  ## bond interfaces.
  # bond_interfaces = ["bond0"]
```

## Measurements & Fields

- bond
  - active_slave (for active-backup mode)
  - status

- bond_slave
  - failures
  - status
  - count

## Description

```shell
active_slave
  Currently active slave interface for active-backup mode.

status
  Status of bond interface or bonds's slave interface (down = 0, up = 1).

failures
  Amount of failures for bond's slave interface.

count
  Number of slaves attached to bond
```

  bond_interfaces = ["bond0", "bond1"]
```

Run:

```shell
telegraf --config telegraf.conf --input-filter bond --test
```
