A node is defined as any device with an IP address. Network Performance Monitor nodes typically include routers, switches, e-mail servers, application servers, and workstations. Nodes are not required to be on the same network, though they must be reachable from the computer with Network Performance Monitor installed.

  1. Click Nodes > Add Node.
    To add an interface, click Interfaces > Add Interface.
  2. Enter or select the device name or IP address, and then click Next.
    To support dynamic IP address assignment, select Device uses a dynamic IP address (DHCP or BOOTP).
  3. If the device supports SNMP version 1 or version 2, click Community string, and then enter the community string.
    If you specify a community string that has not been saved previously, you are prompted to save the credentials. Select yes to make the community string available in other tools that support the shared credentials database. To be able to shut down an interface remotely, you must provide a read and write community string.
  4. If the device supports SNMP version 3, complete the following procedure:
    1. Select a credential set from the list, or click Add to create a new credential set and save it in the shared credentials database.
    2. If you are adding a new credential set, specify the information:

      Credential set The name that represents the credentials you specify on the Add Credentials window.
      This name is displayed in the SNMP Version 3 list in Toolset tools that support the shared credentials database.
      Context A named designation, similar to a group or domain name, to which the user name belongs.
      Context is mandatory if it has been defined for the object being managed.
      User name The name of the user with access to the device.
      Authentication type The authentication to use for logging on to the device, for example, MD5.
      Authentication password/key The password or key that corresponds to the authentication selected.
      Encryption type The encryption used when communicating with the device, for example, DES (56bit) or AES (128 or 256 bit) encryption.
      Encryption password/key the password or key that corresponds to the encryption selected.

    To be able to shut down an interface remotely, you must provide read and write credentials.

If the device does not support SNMP, click Device does not support SNMP.
You can monitor latency, packet loss, and availability of a node without SNMP support.

To add your selections to the database and begin monitoring, select the options on the Resource window, and then click OK.
If you have provided valid SNMP credentials, you can select CPU and memory utilization resource monitoring, volume, disk-based virtual and physical memory utilization, and interface traffic and error charting. If your device does not support SNMP or you do not have the credentials, the device is added to the left pane without displaying the Resource window.

Resource

What is Monitored

CPU

CPU load as percentage of capacity

Memory

Memory and buffer utilization as total usage and percentage of capacity

Volume

Memory and buffer utilization as total usage and percentage of capacity

Interface

Bandwidth utilization, percentage of capacity, errors and discards, and total bytes transferred
