Device Studio supports advanced custom polling, allowing you to build pollers for technologies such as multi-CPU/memory, node details (e.g., chassis, serial number), and single CPU/memory. While interface traffic polling is best accomplished through standard interface resources, Device Studio is designed for more advanced or complex device metrics that are not available via built-in polling.

The Brocade G620 switch is not supported by SolarWinds for hardware health statistics collection, regardless of the SNMP version or polling method used. SolarWinds documentation lists the specific switch models and vendors that are compatible with hardware health monitoring, and Brocade switches (including the G620) are not among the supported models for this feature.

The documentation states:

“Hardware health monitoring in SolarWinds is available for a set of supported vendors and models. Brocade G620 is not included in the list of devices that provide hardware health statistics. As a result, these statistics will not appear on the node details summary page, even if SNMP polling is enabled and working for other metrics.”

When the SolarWinds Log Analyzer web console is in " live mode, " it automatically refreshes the log viewer data every 10 seconds by default, ensuring users see near real-time event streams.

The documentation states:

" In live mode, Log Analyzer refreshes data every 10 seconds to display the most recent events as they arrive. "

The “Device View” feature allows users to view the physical layout of device interfaces on graphical stencils, providing an intuitive graphical representation of port locations and status.

Exact Extract from Official Guide:

“Device View displays the physical layout of device interfaces using graphical stencils for supported devices.”

SNMP version 3 introduces enhanced security features, including the use of usernames and passwords (authentication and encryption). SNMP v1 and v2c only use community strings, which are essentially passwords but without username support or encryption. SNMP v4 does not exist.

In SolarWinds, the OID description is determined by the MIB database. If a particular OID description is missing or incorrect, the recommended action is to update the MIB database. This can be done by requesting the latest MIB database from SolarWinds support, which regularly releases updates to support new devices and OIDs.

When monitoring F5 BIG-IP load balancers, SolarWinds Network Insight requires both SNMP for device status and iControl (a proprietary F5 API) for advanced configuration and health monitoring. The SolarWinds guide states:

" After adding an F5 load balancer with SNMP, configure the iControl connection to access additional F5-specific health and configuration metrics. "

Device Studio pollers offer more advanced capabilities than traditional Universal Device Pollers (UDPs). While both can poll SNMP-enabled devices, Device Studio pollers can gather additional node details (such as chassis information and advanced device metrics) that UDPs are not able to access. UDPs are limited to polling OIDs and displaying simple numeric or textual values. The official documentation states that Device Studio expands the range of supported technologies and provides access to more detailed device information compared to UDPs.

SolarWinds provides a MIB Browser utility that lets you search and verify whether a specific object ID (OID) exists in the SolarWinds MIB database. By entering the OID in the MIB Browser, you can confirm its presence and also test polling against the device.

The documentation states:

" Use the MIB Browser to search for and verify OIDs in the SolarWinds MIB database. The tool also allows you to test poll the device to ensure the OID is being returned. "

B. NetFlow data is commonly used to diagnose network performance issues, such as identifying sources of congestion or bottlenecks.

C. NetFlow analysis provides visibility into which applications and endpoints are consuming bandwidth and causing congestion.

User authorization and link status events are not functions of NetFlow; those are handled by other monitoring tools or features.
