Occasionally, Corente Cloud Services Exchange may need to notify you about problems or events that occur with this Corente Services Gateway. The Alerts tab is used to configure your preferences for these alerts. These alerts can be delivered in the form of notification emails to the addresses that you specify and SNMP traps. One or more notification methods may be unavailable for each type of alert, depending on how you have configured this Location.
Note that you can view Active Alarms, Cleared Alarms, and Events that have been generated in this domain (and specifically from this Location) with the Alarms and Events feature in App Net Manager. You will also be able to view Active Alarms generated by Locations and tunnel connections on the map.
To configure alerting for this Location, fill out the following sections of this screen:
Email Addresses to Receive Alerts
In this section, you can either select the Use Default Emails option defined in the Preferences option, to use the default email addresses that you supplied in the domain contact information, or manually specify email addresses that will receive the alerts. You can edit or delete any existing email address in the email list.
To add a new email address, select the Add button, enter the address, and then click the OK button to store your addition.
Tunnel Alarms
This section contains the following options:
Notify on configuration alerts: When this option is selected, the service will send an email notification and SNMP trap if a User Group of this Location has a configuration problem. Your Location and its tunnel connections will remain disabled until the configuration problem has been resolved. If this option is not selected, the service will not send a notification email or SNMP trap when this event occurs. The following configuration problems would cause this alert:
This Location's User Groups contain nested subnets, within themselves or within a Location partner's User Groups, and the Allow Locations to be configured with nested subnets option is unchecked on the Network Tab.
The User Groups of this Location overlap with the User Groups of one of its partners and no NAT options have been selected by this Location or its partners.
The User Groups of this Location overlap with the User Groups of one of its partners and the wrong NAT options have been set on this Location or its partners.
Notify on loss of tunnel to SCP: When this option is selected, the service will send an email notification and SNMP trap if this Location becomes disconnected from the Corente SCP. If this option is not selected, the service will not send a notification email or SNMP trap when this event occurs. The email will be sent according to the threshold that you have chosen with the Duration of connection loss before receiving email notification pull-down menu.
Notify on loss of tunnel to Partners: When this option is selected, the service will send an email notification and SNMP trap if this Location becomes disconnected from any of its Location partners. The email will be sent according to the threshold that you have chosen with the Duration of connection loss before receiving email notification pull-down menu. If this option is not selected, the service will not send a notification email or SNMP trap when this event occurs.
Duration of connection loss before receiving email notification: This option allows you to set the length of time before an email notification is triggered, ranging from immediate notification to notification only after 8 hours of downtime. You may also choose to never be notified.
The benefit of immediate notification is that you can respond to any problems as soon as they occur; however, a longer delay prevents unnecessary notifications. For example, your ISP may have an interruption of service for 5 minutes and then re-establish your Internet connection. If you have chosen to be notified immediately, you would receive an email even though Internet connection is re-established quickly. If you have chosen to be notified in 1 hour, by which time the Corente Services Gateway has reconnected to the Corente SCP and its partners, you would avoid this email.
System Alarms
This section contains the following options:
Notify on Software Upgrade: When this option is selected, the service will send an email notification if a software upgrade has occurred. When this option is unselected, no email notifications will be sent when the software is upgraded, even if a reboot of the Corente Services Gateway is required. You cannot choose to be notified of this alarm by an SNMP trap.
Notify on Failover: When this option is selected, the service will send an email notification and SNMP trap if a hardware switch (when using Redundant Hardware) or traffic failover has occurred for this Corente Services Gateway. If this option is not selected, the service will not send a notification email or SNMP trap when this event occurs.
Notify on Security Alert: When this option is selected, the service will send an email notification and SNMP trap if a security alert occurs on this Location or one of its tunnels. If this option is not selected, the service will not send a notification email or SNMP trap when this event occurs.
