## Examples

* [Run Kapacitor with default settings](#run-kapacitor-with-default-settings)
* [Run Kapacitor with custom configuration settings](#run-kapacitor-with-custom-configuration-settings)

### Run Kapacitor with default settings

```sh
kapacitord
```

### Run Kapacitor with custom configuration settings

```sh
kapacitord -config /path/to/kapacitor.conf
```

### Disable alert handlers

Disabling alert handlers can be useful for security reasons–for example,
disabling the `exec` handler on a shared system.

```sh
kapacitord -disable-handlers exec,mqtt
```

### Change Kapacitor logging settings

```sh
kapacitord \
  -log-file /path/to/kapacitor.log \
  -log-level debug
```

### Blacklist HTTP GET or POST operations from specific CIDRs

```sh
kapacitord -blacklist-cidrs 10.10.0.0/16,192.168.200.5/30
```
