## Decide what happens when there's no signal

Loss of signal occurs when New Relic stops receiving data for a while; technically, we detect loss of signal after a significant amount of time has elapsed since data was last received in a time series. Loss of signal can be used to trigger or resolve a violation, which you can use to set up alerts.

You can configure loss of signal settings by condition in the UI or [configure loss of signal via the NerdGraph API](/docs/alerts-applied-intelligence/new-relic-alerts/advanced-alerts/alerts-nerdgraph/nerdgraph-api-loss-signal-gap-filling/#loss-of-signal).

## Use non-null values when there's no signal

By default, gaps in data signals are filled with null values. In cases where you need to be able to create conditions based on those data gaps, you can fill gaps with a custom value or the last known value. You can configure this setting by condition in the UI or [configure gap filling values via NerdGraph](/docs/alerts-applied-intelligence/new-relic-alerts/advanced-alerts/alerts-nerdgraph/nerdgraph-api-loss-signal-gap-filling/#customize)
