Configuring Scalability Pollers in WhatsUp Gold

Poller Configurations displays a list of scalability pollers currently in or available for use with WhatsUp Gold. The status of each poller is indicated by color. Green indicates the poller has started, registered with the WhatsUp Gold server, or is currently idle. Yellow indicates the poller is starting, registering with WhatsUp Gold, stopping, or restarting. Red indicates an error has occurred, the poller cannot be found, or the status is unknown. Poller status can also be viewed using the Poller Health dashboard report.

Use the following controls to manage scalability pollers:



Click this icon to create a new poller record.	Click this icon to edit an existing poller record.	Click this icon to remove a poller record.	Click this icon to refresh poller status and reported data.
Note: Using these controls affects the poller configurations stored in WhatsUp Gold and does not modify the actual poller applications installed on remote machines.

When configuring poller settings for either a new or existing record, first enter a name for the poller. This name should match the name used when installing and configuring the poller application on the remote machine. Then, use enable the poller and, if enabled, use the poller for load balancing. At least one poller must be configured for load balancing at all times to ensure all devices are being polled.

Now, you can use the Devices tab to select the device(s) you want to apply to the poller. Click Add, then select a single device, multiple devices, or device group from the list, and click OK.

You can also assign a subnet to a poller. Select the Subnets tab, then click Add. Enter the subnet address in the x.x.x.x/xx format and click OK. Please note, the specified subnet must include devices discovered by WhatsUp Gold.

Important: Any devices assigned to a given poller, either directly or through a subnet assignment, are automatically reallocated to a suitable load-balanced poller should that assigned poller be disabled or go offline to ensure every device is polled.

Please note, all load-balanced pollers must have sufficient IP network access to all devices regardless of how you may have assigned devices to particular pollers to ensure any device can be successfully polled from any load-balanced poller. Similarly, any non-load-balanced poller must have sufficient IP network access to any devices assigned to it, either directly or through subnet assignment. "Sufficient IP network access" indicates a network configuration which allows for ICMP, SNMP, and WMI protocols to communicate with the polled devices.

To see which devices are monitored by a specific poller, click the hyperlinked total under the "Polled Devices" column for that poller to launch a dedicated dialog displaying a device list. Please note, for ease of use, the list is searchable using the field at the top of the dialog. Additionally, you can access the Device Properties and Device Status interfaces for any device shown directly from this dialog by clicking the menu icon to the left of the target device name/IP address, then selecting either Device Properties or Device Status from the menu displayed.
