User interface elements are described below:

UI Elements


Source Machine

The name of the source machine from which you want the network path monitoring to begin.

Note: To run the Network Delay Monitor when there are firewalls between the Performance Center Host machine and the source machine, type the server name or IP address of the source machine according to the format:

<MI Listener machine>:<source machine local key>

Where source machine local key is the unique key that you chose when configuring the Performance Center agent on the source machine.


For details about working with firewalls in Performance Center, see the firewall section in the Performance Center Installation Guide.


The platform on which the machine runs.

Destination Machine

The name of the machine at the final destination of the path you want to monitor.

Note: If the destination machine is localhost, type the local machine's name and not localhost.

Monitor Settings
  • Send Request Using X protocol. Select the relevant protocol. It is recommended that you keep the default protocol. In Windows, the default is TCP, and in UNIX, the default is UDP.

  • Send request to port X. Enter the port number being used by the network path.

  • Enable display of network nodes by DNS names. Select to view the DNS name of each node along the network path, in addition to its IP address. Note that selecting this option decreases the speed of the Network monitor.

Monitor Frequency

Send next packet X milliseconds after receipt of previous packet. Select the number of milliseconds the monitor should wait between receiving a packet and sending out the next packet. If you have a long, steady performance test, you can increase the interval by several seconds.

Default: 3000 milliseconds

Monitoring Packet Retries
  • Wait X seconds for packet to return before retrying. Select the maximum number of seconds that the monitor should wait for a packet to return before it retries to send the packet.

    Default: 3 seconds. If your network is very large and loaded (an internet connection with a low capacity), increase the value by several seconds. If you have a small network (such as a LAN), decrease the value.

  • Number of retries. Select the number of times the Network monitor should try resending a packet to a node if the packet is not initially returned.

    Default: 0

Restores the default monitor property values.
