When displaying Universal Device Poller (UDP) data in different web console views, each view must be configured to show the UDP results as charts.

From the documentation:

“In the Universal Device Poller application, under the Web Display tab, you must check the ‘chart’ box for every web view where you want to display the poller data. If the box is not checked for the current view, the data will not be visible as a chart widget.”

Enabling DNS resolution but not storing hostnames immediately results in:

Reduced database memory/storage used for DNS info, as hostnames aren’t stored with each flow record.

Less database space used for flows, since flow records will reference IPs rather than resolved DNS names.

Reduced SQL server reads/writes since the platform does not immediately resolve and store hostnames with every received flow, decreasing load.

DNS names will still appear in reports where resolved dynamically, so option C is incorrect.

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.

Flow collectors differ from polling engines because they passively receive and process flow records sent by network devices, while polling engines actively poll devices for data (like SNMP). Devices must be explicitly configured to export their NetFlow, sFlow, or J-Flow records to the IP address and port of the flow collector, rather than being queried by the SolarWinds server.

The documentation states:

"To monitor flow data, devices must be configured to send their flow records to the collector. Unlike traditional polling, the collector does not initiate contact; it listens for incoming flow exports from network devices."

To test connections from two separate locations using NetPath or similar functionality in Hybrid Cloud Observability, you need to create two probes and assign each probe to an agent at each respective location. This allows network path and experience monitoring from the point of view of both locations.

Exact Extract from Official Guide:

“To monitor network paths from multiple locations, create a separate probe for each location and assign the probe to an agent deployed at that site.”
