There are several options to avoid unnecessary notifications.
- The Check “CPU utilization for simple devices” offers several tuning knobs where not only the thresholds, but also timeranges in which a value exceeds the threshold can be tuned.
- You should always use the rulesets “Maximum number of check attemps for hosts/services” to define the number of checks until the hard state is reached.
- You can consider delaying notifications for specific services if they are still too noisy.
- You can use time ranges for notifications, so that no notification is generated during the daily backup.
- As a last option, you can turn off notifications for specific services completely.
