A. MIB files define the available SNMP objects and metrics that can be polled from a device.

C. MIB files provide human-readable names and descriptions for OIDs, allowing SolarWinds to display metrics in a clear, user-friendly format instead of raw OID numbers.

Automatic device discovery is handled by network scanning, not by MIB files, and OIDs are created by device vendors, not by SolarWinds.

For critical devices and connections, peak calculation is the recommended capacity planning method. This approach uses the highest observed utilization values within a time period, ensuring that planning accounts for maximum network demand and helps avoid bottlenecks during traffic spikes. SolarWinds documentation advises using peak calculations for important links to ensure network reliability and performance.

The SolarWinds platform uses the concept of "dependencies" to handle parent-child relationships. When you configure dependencies (via Manage Dependencies), child objects such as interfaces will show as "unreachable" if the parent node is "down" or unresponsive, rather than "down" or "unknown".

"The Manage Dependencies feature allows administrators to specify parent-child relationships. If a parent device is down, all child objects will be marked as 'unreachable', preventing unnecessary alerts and false positives."

This is a best practice to avoid alert storms and to properly reflect network hierarchy.

A. A different port is being used: If MSSQL traffic is sent on a port different from the default (1433), SolarWinds may not classify it as MSSQL unless custom mapping is defined.

C. The source or the destination port field is not present: Application mapping relies on port information; missing fields prevent classification.

The documentation states:

"Unclassified traffic may result when known applications use non-default ports or when flow records lack required port information for mapping."

SolarWinds provides the flow alert wizard as the tool to configure and manage flow alerts. This wizard guides administrators through selecting the relevant flow metrics and alert thresholds.

The documentation states:

"Use the Flow Alert Wizard to define and manage alerts on flow-based data, allowing for rapid detection and notification of anomalous network activity."

Custom pollers are typically created when you need to monitor metrics or OIDs that are not supported by default in SolarWinds:

Monitor specific metric that is not out-of-the-box: If a device exposes a metric not natively monitored by SolarWinds, you must create a custom poller for that metric.

Monitor unsupported object ID: For any OID that is not included in default templates, a custom poller is necessary.

Monitoring special equipment or devices without WMI might also need custom pollers, but the requirement specifically applies when you need to access non-standard metrics or OIDs.

Duplicate flows can occur if multiple interfaces export the same data or if NetFlow is configured on both ingress and egress interfaces. SolarWinds documentation recommends:

Enabling the “flow de-duplication” feature within NetFlow Traffic Analyzer to automatically filter duplicate data.

Ensuring NetFlow is enabled only on ingress interfaces (best practice), as enabling it on both directions can result in duplicate records.

Automatic addition of flow sources and enabling on sub-interfaces do not directly address duplication.

If only response time and packet loss are visible, the node is currently being polled via ICMP (ping), which does not provide detailed statistics like CPU, memory, or interface data. Switching the polling method to SNMP enables SolarWinds to gather detailed device metrics and statistics, as SNMP supports comprehensive monitoring.
