Optional. Will open warning-level incident and may send notifications depending on the policy's issue creation preference setting and any workflow you may have configured. Use a warning threshold if you want to monitor when a system behavior is concerning or noteworthy but not important enough to require a critical-level threshold.
A loss of signal is a period of time when no data is received by New Relic. This could be the result of an entity or service going offline, a problem with an agent or collector, or networking problems in a data center or the internet. You can use loss of signal detection to create a new incident if a signal stops and you expect a service to be stable. You may also want to use this to determine when an ephemeral service stops and set the action to close any open incidents that exist for this condition.
Different condition types have different minimum time intervals. For example, some condition types have a minimum time interval of 5 minutes (for example, metric alert conditions), and others have a minimum time interval of 1 minute (for example, NRQL alert conditions). The same happens with the maximum time interval, where the amount is 120 minutes.
