Alerting rotations are used to define periods of time in which network alerts are sent to certain users within Sonar. A network alert would be triggered as a result of a network event that occurs. Network events are considered to be when a device moves into a warning state, a down state, or begins flapping. Alerting rotations can be used to setup an on call rotation for specific users, during which they would be alerted about any network events that happen.
- Good: The device is working normally
- Warning: The device has either: violated an ICMP threshold defined in a monitoring template, an SNMP query has failed due to a configuration error (ie an invalid OID), or an SNMP OID threshold has been violated
- Down: The device has failed to respond to ICMP (if ICMP monitoring is enabled), or it has failed to respond to SNMP (if SNMP OIDs are configured)
- Flapping: The device is moving between states in a quick sequence
Alerting Rotation Setup
- Enabled: This is what determines if the alerting rotation is currently being used, or if it is disabled.
- Name: A descriptive name for the rotation.
- Start: The date this rotation should start. This can be set for a future date, but the rotation will not be applied until that date.
- Users: The users that are part of this alerting rotation.
- Repetitions: If Infinite Repetitions is checked, this rotation will repeat forever; if unchecked, this rotation will repeat until the Repetitions value is met and will the stop.
- Weeks Between Repetitions: This is how often the rotation repeats; if 1, it will repeat every week. If 2, it will repeat every other week.
- Warning Time In Minutes Before Alerting: The number of minutes a device can be in warning state before notifications are sent. This is ignored if the device is in warning due to violating an SNMP threshold, as the thresholds themselves have a time parameter.
- Downtime In Minutes Before Alerting: The number of minutes a device must be in down state before an alert is sent out.
- Accounts: If All Accounts is checked, this rotation will be applied to all accounts; otherwise, you can specify which account types and/or groups this rotation should be applied to.
- Network Sites: If All Network Sites is checked off, this rotation will be applied to all network sites; otherwise, you can specify which particular network site(s) this rotation should be applied to.
- Inventory Models: If All Inventory Models is selected, this rotation will be applied to all inventory models; otherwise, you can specify which particular inventory model(s) this rotation should be applied to.
Alerting Rotation Days
Once you have set up an alerting rotation, you can set up the days that the alerting rotation should be active for. You can specify only certain times in particular days of the week, or you can set it up to run all day everyday. To set up the alerting rotation to run 24x7, add each day as an alerting rotation day and set both the start and end times as 12 am.
