Configuring Remote Pollers in WhatsUp Gold
The Pollers Configuration Library 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. |
Please note, using these controls only affects the poller configurations stored in this WhatsUp Gold library and does not modify the actual poller applications installed on remote machines in any way. |

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: If you assign a device to a poller, that device will not be allocated to other Pollers under any circumstances even if the poller is offline due to error or manually disabled in the Pollers Configuration Library. However, any devices not assigned to a specific poller will be allocated to the next most appropriate poller that is both online and has load balancing enabled.
Please note, if you are restricting SNMP access to certain IP addresses in your network and your pollers are participating in load balancing, you must add all of the IP addresses for the pollers to the list of accepted IP addresses. This is necessary to ensure that at least one poller has access to your SNMP polled devices at any given time. If a poller is not participating in load balancing, but is setup to poll a particular subnet, those devices in that subnet must be updated to allow SNMP requests from the associated poller.
