Configuring Alarms Settings

Select this option to clear all devices listed in the Alarms page of all active alarms when the system starts up (cold start event): Critical, Major, Minor, Warning or Info.

Use this setting to prevent historical, dated alarms from cluttering the Alarms page.

[Only relevant if the 'Alarms Automatic Clearing' option is selected]

Clears old alarms after a defined period of days even though a Clear alarm to stop displaying very old active alarms has not been received from the device.

Select this option for device events (events originating from the device) to be automatically cleared from the Alarms page when the system starts up (cold start event).

Device events originating in the OVOC, e.g., adding a gateway, are not cleared when the device is reset. The OVOC consequently employs a mechanism to automatically clear these events from the Alarms page. The feature prevents historical, dated events from cluttering the Alarms page.

Events are by default cleared every three days. You can change the default to suit your requirements.

If an alarms forwarding rule is configured (under Alarms > Forwarding), the alarms can be aggregated to be sent in a single email. This parameter allows you to configure the maximum number of alarms to aggregate in a single email. Default: 10. If, for example, the number of alarms to aggregate is configured to 10 and the time interval (see the next parameter) is configured to 60 seconds, then after 60 seconds, five alarms will be raised according to the alarms forwarding rule and five aggregated alarms will be forwarded.

If an alarms forwarding rule is configured (under Alarms > Forwarding) and the alarms are configured to be aggregated and sent in a single email, you can configure a time interval to determine how often aggregated alarms are forwarded. Default: 60. If, for example, the number of alarms to aggregate is configured to 10 (see the previous parameter) and the time interval is configured to 60 seconds, then after 60 seconds, five alarms will be raised according to the alarms forwarding rule and five aggregated alarms will be forwarded.

Select this option for an 'Alarm Suppression' alarm to be generated when the OVOC server identifies that the number of alarms of the same type and from the same source, generated in a time period, is greater than the number defined in the threshold. At this point, these alarms are not added to the database and are not forwarded to configured destinations.

[Only applicable if 'Alarms Suppression' is selected] Lets you configure a counter threshold (Default: 10 alarms) and interval (Default: 10 seconds). For example, if 10 alarms are generated from 'Board#1/EthernetLink#2 in 10 seconds, then alarms from this source are suppressed and the 'Suppression' alarm is generated. This alarm is cleared if in the subsequent 10 second interval, less than 10 alarms are sent from this source. At this point, updating the OVOC database is resumed (the last received alarm is updated).

During the time the suppression alarm is active, the OVOC server updates the database with a single alarm (with updated unique ID) database every minute, until the alarm is cleared.

Select this option for the Live Platform to generate SNMP Keep-alive traps to 3rd-party applications, such as a Syslog server. This trap can be sent to either the SNMP, Syslog or Mail server destination. You can send the Keep-Alive trap to the target destination, according to an existing configured forwarding destination rule.
