+# 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. 
+
+![alarms collector](https://user-images.githubusercontent.com/1153921/101641493-0b086a80-39ef-11eb-9f55-0713e5dfb19f.png)
+
+## 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`
