window, as described in Configuring Node Interface Poll Settings in Chapter 4). This would override the polling refresh rate of the database (once per 50 seconds), by instead having NetSight Element Manager issue a once-hourly poll to that individual node.

However, you cannot configure polling so that contact status with an individual node is refreshed more frequently than the refresh rate established by the Node database polling settings. Even if you configured one of your 100 managed nodes to be polled every 10 seconds for contact status, it would still be subject to the refresh rate of the entire node database. In actuality, its contact status would only be updated once during the 50 seconds it takes to fully poll the node database.

If you have a mission-critical node, you can keep Chassis Manager running to be constantly appraised of its contact status. Because the Chassis Manager application uses its own polling mechanism (independent of the node database polling in NetSight Element Manager), you can determine the status of the node by using the Contact Status symbol in Chassis Manager’s Logical View window. Refer to your individual device-specific User’s Guides for more information on using Chassis Manager; refer to the Device Management Options section, following, for more information on setting the Chassis Manager poll settings. You can also issue an immediate status poll at any time via the Query Status options described above.

Use the following fields to establish the refresh rate of polling for all nodes in your node database:

Interval (sec)

The amount of time that elapses between groups of poll packets. The number of intervals required to complete a poll cycle will depend on how many devices are in your node database, and how many are being polled during each interval.

To set the Interval value:

1.Click in the Interval text field, and type in the number of seconds you want NetSight Element Manager to wait between each set of polling packets. The range is from 1 to 60 seconds; the default is 5 seconds.

Packets

The number of poll packets that will be sent to devices eligible for polling during each polling interval.

To set the Packets (number of polled devices) value:

1.Click in the Packets text field, and type in the number of IP devices you want polled during each poll Interval. The range is from 1 to 25.

To determine the amount of time it will take NetSight Element Manager to complete one poll of all nodes in your database, divide the number of nodes in your database by the Packets value and multiply by the Interval (sec) value.
