Trap Receiver

 

The Trap Receiver is a utility used for receiving traps from the BMC. In the event of a sensor error or a sensor reading that exceeds a threshold, the BMC will send SNMP traps to the destinations set in the BMC. The Trap Receiver is executed on the destination site and receives the SNMP trap from multiple senders (BMCs). If you select a category you can see all the traps in that category. Furthermore, when you click a trap in the trap list, you can see its details in the Trap Structure window. Please refer to the BMC Setting page to set the SNMP destination.

 

As shown in Figure 12-1, there are several components to the IPMI Trap Receiver.

1)      Menu Bar: contains pull-down menus for exiting the program, getting help, etc.

2)      Tool Bar: contains all IPMI Trap Receiver functions.

3)      Category: categorizes the traps by sender, community and sensor.

4)      Trap Structure: a tree structure for displaying trap details.

5)      Status Bar: shows messages regarding the current status.

6)      Trap List: shows detailed information for received traps.

Category

There are three categories (each with a tab used to select it): Sender, Community and Sensor, as shown in Figure 12-4. The Sender page lists all the sender IP addresses. The Community page lists all the SNMP communities. The Sensor page lists all the sensor types from the traps. Clicking on each category type will act as a filter for all traps in the traps list. Click on the ¡§All¡¨ button to cancel all filters.

 

  

 

Figure 12-4

Once a category has been selected, the filter condition will be shown at the bottom of the trap list. See Figure 12-5 as an example: the filter is ¡§Sender = 192.168.10.245, Community = public, Sensor = CPU 1¡¨. The trap list displays only those traps whose contents are included in each of the three filters.

Receiving a Trap

When the Trap Receiver receives a trap from the BMC, an alert bar will pop up on the screen and remain for 10 seconds to notify you that a trap has occurred.  In addition, an email alert will be sent out according to the information field settings in the Email Alert dialog box. Please refer to Figure 12-7.

 

The email content will include the following information:

 

A SNMP trap received
Sender:192.168.10.247
Sensor:FAN 2
Description:Lower Non-recoverable - going low
Time:2005/11/22 14:27:07 Tue
