HP Network Node Manager 9 : Discovering and Monitoring Your Network - Examining discovery results (part 4)

Example

As a state poller configuration example, let's take the previously described network (the diagram in the section entitled How to plan state polling), and configure state poller to fulfill the following requirements:

• All nodes need to be polled using SNMP every five minutes, except the objects described as follows:
  • All interfaces with the name DataCenter should be polled every one minute using SNMP.
  • There are two HP printers in the NOC subnet, which are connected to a network but do not support SNMP, so they need to be polled using ICMP every five minutes.

Complete the following steps to configure state polling according to requirements:

1. Set global monitoring settings by completing following steps:
   1. Select Monitoring Configuration in Configuration workspace.
   2. Select the Default Settings tab.
   3. Set Fault Polling Interval to 5 minutes.
   4. Make sure Enable SNMP interface Fault Polling is checked and Enable ICMP Management Address Polling is unchecked.
      
2. Configure all interfaces with the interface name Data Center to be polled every one minute using SNMP:
   1. Select Interface Settings tab:
      
   2. Select New on Interface group field.
   3. Name the interface group, that is, Datacenter interfaces.
   4. Select Additional filters tab.
   5. Select the following values: Attribute = IfAlias, Operator = =, and Value = Data Center.
   6. Click Append.
      
   7. Click Save and Close.
   8. Make sure Enable SNMP Interface Fault Polling is selected and Enable ICMP Management Address Polling is unchecked.
   9. Set ordering number, that is, 150.
   10. Set Fault Polling Interval to 1 minute.
       
   11. Click Save and Close.
3. Configure HP printers to be polled every five minutes using ICMP:
   1. Select Node Settings tab.
   2. Select New.
   3. Set ordering number, that is, 150.
   4. Set Enable ICMP Fault Polling.
   5. Uncheck Enable SNMP interface Fault Polling.
   6. Make sure that Fault Polling interval is set to 5 minutes.
   7. Select New in Node group.
   8. Enter name in Name field, that is, Printers.
   9. Select Device Filters tab.
   10. Select New.
       
   11. Select the following value in the device filter window: Device Category = Printer, Device Vendor = Hewlett-Packard.
   12. Click Save and Close.
       
   13. Select Save.
   14. Select Actions | Show Members to see whether devices are included in your filter.

       Tip

       You won't see printers if you don't have them in your discovered topology. In a real life scenario, you can always use Show member to check whether you have properly configured the filter scope.
