# Alarms - graphing Netdata alarm states over time

This collector creates an 'Alarms' menu with one line plot showing alarm states over time. Alarm states are mapped to integer values according to the below default mapping. Any alarm status types not in this mapping will be ignored (Note: This mapping can be changed by editing the `status_map` in the `alarms.conf` file). If you would like to learn more about the different alarm statuses check out the docs [here](https://learn.netdata.cloud/docs/agent/health/reference#alarm-statuses).

```
{
    'CLEAR': 0, 
    'WARNING': 1, 
    'CRITICAL': 2
}
```

## Charts

Below is an example of the chart produced when running `stress-ng --all 2` for a few minutes. You can see the various warning and critical alarms raised.

## Configuration

Enable the collector and restart Netdata.

```bash
cd /etc/netdata/
sudo ./edit-config python.d.conf
# Set `alarms: no` to `alarms: yes`
sudo systemctl restart netdata
```

If needed, edit the `python.d/alarms.conf` configuration file using `edit-config` from the your agent's [config
directory](/docs/configure/nodes.md), which is usually at `/etc/netdata`.

```bash
cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/alarms.conf
```

The `alarms` specific part of the `alarms.conf` file should look like this:

```yaml
# what url to pull data from
local:
  url: 'http://127.0.0.1:19999/api/v1/alarms?all'
  # define how to map alarm status to numbers for the chart
  status_map:
    CLEAR: 0
    WARNING: 1
    CRITICAL: 2
```

It will default to pulling all alarms at each time step from the Netdata rest api at `http://127.0.0.1:19999/api/v1/alarms?all`
