SolarWinds capacity forecasting accuracy improves when:

More historical data is used: The more historical data points included in calculations, the better the forecasting model will perform.

Using average daily values for calculations: This smooths out anomalies and provides a more accurate trend, as recommended in the documentation:

“To improve the precision of capacity forecasting, use as much historical data as possible and set calculations to use average daily values.”

Monitoring with platform agents or adjusting thresholds affects alerting, not trend accuracy.

To receive and process flow data, SolarWinds NTA/HCO must have flow sources enabled and must listen on the correct flow collection port. SolarWinds states that flow-enabled nodes and interfaces must be monitored before they can be recognized as flow sources in NTA, so monitoring the relevant interfaces under flow sources is required. SolarWinds also documents UDP port 2055 as the default port for receiving flows on an NTA collector. Port 1434 is related to SQL Server Browser/dynamic SQL discovery scenarios, not NetFlow collection. Adding nodes directly to “NetFlow endpoints” is not the correct SolarWinds configuration model; devices and interfaces are monitored and then enabled as flow sources.

===============

Device Studio supports the following data sources:

Calculated result from transformation of polled values: You can apply calculations (such as average, sum, transformation) to the raw polled data.

Polled value by a device on an object ID: Device Studio can directly poll an OID from a device and use its value for monitoring.

Night/day standard deviation and predicted/baseline values are not direct data sources in Device Studio.

SolarWinds ' log processing policies for svslog (syslog) and traps (SNMP traps) are processed independently and concurrently. This is because syslog and SNMP trap processing are separate services with their own processing pipelines, unlike the global pre and post policies which affect overall log routing or rule order.

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.”

NetFlow is the Cisco IOS feature designed for monitoring and analyzing network traffic to pinpoint specific applications or endpoints consuming bandwidth or causing network slowness. It captures detailed flow information, including source/destination, ports, and protocols.

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.

The SolarWinds MIB database is used for SNMP-based monitoring and performs these critical functions:

A. It defines which OIDs are recognized and what metrics can be polled via Universal Device Pollers or other custom monitors.

C. It maps OIDs (numeric identifiers) to their human-readable textual names for reporting and alerting.

Options B and D are not accurate; the database does not enable automatic polling nor does it update device OIDs during polling.

In SolarWinds Universal Device Poller (UDP), the column get type is used to retrieve values from a particular column of an SNMP table, meaning you get all the values for that column across multiple rows.

SolarWinds NTA processes flow data via a dedicated collector component. Devices are configured to export flow records to the NTA collector, which ingests, stores, and analyzes the data.

" NetFlow Traffic Analyzer receives flow data from network devices using the NetFlow Collector service, which processes and stores traffic information for analysis. "

No agent is required on target devices, and the collector is the key processing method.
