+# Stop notifications for individual alarms
+
+In this short tutorial, you'll learn how to stop notifications for individual alarms in Netdata's health
+monitoring system. We also refer to this process as _silencing_ the alarm.
+
+Why silence alarms? We designed Netdata's pre-configured alarms  for production systems, so they might not be 
+relevant if you run Netdata on your laptop or a small virtual server. If they're not helpful, they can be a distraction
+to real issues with health and performance.
+
+Silencing individual alarms is an excellent solution for situations where you're not interested in seeing a specific
+alarm but don't want to disable a [notification system](/health/notifications/README.md) entirely. 
+
+## Find the alarm configuration file
+
+To silence an alarm, you need to know where to find its configuration file.
+
+Let's use the `system.cpu` chart as an example. It's the first chart you'll see on most Netdata dashboards.
+
+To figure out which file you need to edit, open up Netdata's dashboard and, click the **Alarms** button at the top
+of the dashboard, followed by clicking on the **All** tab.
+
+In this example, we're looking for the `system - cpu` entity, which, when opened, looks like this:
+
+![The system - cpu alarm
+entity](https://user-images.githubusercontent.com/1153921/67034648-ebb4cc80-f0cc-11e9-9d49-1023629924f5.png)
+
+In the `source` row, you see that this chart is getting its configuration from
+`4@/usr/lib/netdata/conf.d/health.d/cpu.conf`. The relevant part of begins at `health.d`: `health.d/cpu.conf`. That's
+the file you need to edit if you want to silence this alarm.
+
+For more information about editing or referencing health configuration files on your system, see the [health
+quickstart](/health/QUICKSTART.md#edit-health-configuration-files).
+
+## Edit the file to enable silencing
+
+To edit `health.d/cpu.conf`, use `edit-config` from inside of your Netdata configuration directory.
+
+```bash
+cd /etc/netdata/ # Replace with your Netdata configuration directory, if not /etc/netdata/
+./edit-config health.d/cpu.conf
+```
+
+> You may need to use `sudo` or another method of elevating your privileges.
+
+The beginning of the file looks like this:
+
+```yaml
+template: 10min_cpu_usage
+ on: system.cpu
+ os: linux
+ hosts: *
+ lookup: average -10m unaligned of user,system,softirq,irq,guest
+ units: %
+ every: 1m
+ warn: $this > (($status >= $WARNING) ? (75) : (85))
+ crit: $this > (($status == $CRITICAL) ? (85) : (95))
+ delay: down 15m multiplier 1.5 max 1h
+ info: average cpu utilization for the last 10 minutes (excluding iowait, nice and steal)
+ to: sysadmin
+```
+
+To silence this alarm, change `sysadmin` to `silent`.
+
+```yaml
+ to: silent
+```
+
+Use one of the available [methods](/health/QUICKSTART.md#reload-health-configuration) to reload your health configuration 
+ and ensure you get no more notifications about that alarm**.
+
+You can add `to: silent` to any alarm you'd rather not bother you with notifications.
+
+## What's next?
+
+You should now know the fundamentals behind silencing any individual alarm in Netdata.
+
+To learn about _all_ of Netdata's health configuration possibilities, visit the [health reference
+guide](/health/REFERENCE.md), or check out other [tutorials on health monitoring](/health/README.md#guides).
+
+Or, take better control over how you get notified about alarms via the [notification
+system](/health/notifications/README.md).
+
+You can also use Netdata's [Health Management API](/web/api/health/README.md#health-management-api) to control health
+checks and notifications while Netdata runs. With this API, you can disable health checks during a maintenance window or
+backup process, for example.
