An alarm rule defines the condition which triggers an alarm. When an incident that complies with the alarm rule happens, system will detect that incident and generate an alarm message.
There are three alarm categories: device alarms, application alarms and network service alarms.
Configuring Interface Bandwidth
If you intend to use the interface alarm rule, make sure that you have configured the interface bandwidth. Both are indispensable, otherwise you will not receive the alarms.
To configure the detection rule, take the following steps:
- Click System> Alarm Rule > Rule.
- Click Interface Bandwidth Configuration at the top-right corner.
- In Interface dialog box, click Add.
- Click OK.
|Interface||From the Interface drop-down list, select the interface that you want to enable the monitor function.|
|Interval||In the Detect Interval text box, specify the detect interval. The range is from 5s to 30s. The default value is 10s.|
|Outbound Bandwidth||Specify the maximum outbound bandwidth. The range is from 1Kbps to 10,000,000Kbps. The default value is 1,000,000Kbps.|
|Inbound Bandwidth||Specify the maximum inbound bandwidth. The range is from 1Kbps to 10,000,000Kbps. The default value is 1,000,000Kbps.|
|Restore Default||Click Restore Default to restore the value to the default one.|
Creating an Alarm Rule
To create an alarm rule, take the following steps:
- Select System > Alarm Rule.
- Click New.In the Alarm Rule Configuration dialog box, configure these values.
Option Description Rule Name Specify the rule name. You can input 31 characters at most. Rule Type Specify the description of the warning rule. You can input 255 characters at most. Trigger
Specify the trigger of the warning, including the monitored object and the threshold.
Select the monitored objects from the drop-down menu and then select the threshold. Generally, there are two types of thresholds: the threshold within a period, and the threshold at a specific point of time. Administrators can use both of them or one of them. If administrators use both of them, the logical relation between them is "or", which means system will generate the warning information when one threshold meets the settings.
Note: If the monitored object is New Sessions, Concurrent Sessions, or Interface Bandwidth, the threshold is percentage.
Advanced Schedule Specify the schedule of the warning rule from the drop-down list. The warning rule will take effect during the specified period of time, which is decided by the schedule. You can also click New Schedule in the drop-down list to create a new schedule. Severity Specify the severity of the incident. Alarm mode
Specify the alarming method .
- Send via Email: Select the checkbox and then specify a recipient or create a new recipient from the Recipient drop-down menu. System will report the events to the recipient by sending a warning email. To create or edit a recipient, go to Object > Send Object (refer to Send Object).
Send via SMS: Select the checkbox and then specify a recipient or create a new recipient from the Recipient drop-down menu. System will report the events to the recipient by sending a mobile phone text message. To create or edit a recipient, go to Object > Send Object (refer to Send Object).
- Send via Trap: Select the checkbox, and system will send messages to the Trap host when an event occurs. To configure a Trap host, go to System > SNMP (refer to SNMP).
Note: If you use "Send via Trap", you must designate a SNMP host and Trap host at the same time.
Description Specify the description of the rule. You can input 255 characters at most.
