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: + + + +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) ?

With this API, you can disable health checks during a maintenance window or +backup process, for example. + +[](<>) |
