24.4.2 Selecting a polling protocol

NNM netmon polling process

By default, the netmon process uses ICMP to poll individual addresses (individual addresses are viewed as being the same as interfaces). You can also configure NNM so that the netmon process uses SNMP instead of ICMP depending on the devices (SNMP and ICMP are never used at the same time). To determine whether there is any area in which SNMP is being used, check the following file:

• Windows: %OV_CONF%\netmon.snmpStatus

• UNIX: $OV_CONF/netmon.snmpStatus

NNMi polling process

In NNMi, sets of node and interfaces are defined as node groups and interface groups, respectively. The polling policy is applied to node groups and interface groups on the Monitoring Configuration form.

NNMi polling configuration example

For example, to set polling in a VOIP router set (using SNMP and ping), do the following:

1. Using the Node Groups form, create a node group for identifying the VOIP router. Save this form and close the window.

   

2. On the Monitoring Configuration form, add new node settings as follows:

   

3. After specifying ordering values, choose Quick Find from the Node Groups field.

   

4. Select the node group for setting monitoring as follows:

   

5. Select the Enable IPAddress Fault Polling check box as shown below. Save the form and close the window.
