Netdata also supports alarm **templates**, so that an alarm can be attached to all the charts of the same context (i.e. all network interfaces, or all disks, or all mysql servers, etc.).

Each alarm can execute a single query to the database using statistical algorithms against past data,
but alarms can be combined. So, if you need 2 queries in the database, you can combine
2 alarms together (both will run a query to the database, and the results can be combined).

+Defines the interval between repeating notifications for the alarms in CRITICAL or WARNING mode. This will override the default interval settings inherited from health settings in `netdata.conf`. The default settings for repeating notifications are `default repeat warning = DURATION` and `default repeat critical = DURATION` which can be found in health stock configuration.

+* `off`: Turns off the repeating feature for the current alarm. This is effective when the default repeat settings has been enabled in health configuration.

`$used` and `$avail` are the `used` and `avail` chart dimensions as shown on the dashboard.
So, the `calc` line finds the percentage of used space. `$this` resolves to this percentage.
+This is a repeating alarm and if the alarm becomes CRITICAL it repeats the notifications every 10 seconds. It also repeats notifications every 2 minutes if the alarm goes into WARNING mode.
