SolarWinds Hybrid-Cloud-Observability-Network-Monitoring Exam With Confidence Using Practice Dumps

Ping the device from the polling engine: Verifies network connectivity and correct polling engine assignment.

Verify hardware health sensors: Ensures the platform is receiving valid sensor data; missing data may indicate sensor or device communication issues.

Adding a remote site node and waiting are not direct troubleshooting steps for missing data on a node that is already “up.”

Exact Extract from Official Guide:

“If a node is up but data is missing, check network connectivity from the polling engine using ping or SNMP walk tools, and verify that hardware health sensors are reporting valid data.”

The “top talkers” feature tracks the highest-bandwidth consumers in your network. Lowering the optimization value means more flows and more detailed data are collected and stored, which can increase the storage requirement on your server.

Exact Extract from Official Guide:

“Decreasing the Top Talkers optimization value results in the storage of more detailed data, which increases the database and storage requirements.”

Comprehensive and Detailed Explanation From Exact Extract:

When the NetFlow collector service is showing a "down" status, the SolarWinds documentation recommends the following troubleshooting steps:

Confirm the database connection is up and server has free resources.

Explanation:The NetFlow collector service relies on connectivity to the SolarWinds database. If the database connection is lost or the server is out of resources (such as CPU or RAM), the service may go down or fail to start. Ensuring that the database is reachable and that the server has enough resources is a primary troubleshooting step.

Start or restart SolarWinds’ NetFlow service from Orion Service Manager.

Explanation:The official troubleshooting guidance instructs administrators to use the Orion Service Manager to start or restart the NetFlow service. This is a direct method to recover the NetFlow collector from a "down" state and is one of the first actions recommended by SolarWinds support.

Options B and C arenotrecommended in the official documentation:

Deleting and re-adding the NetFlow collector service is not a documented troubleshooting step and may cause loss of configuration.

Starting or restarting the generic "collector service" is not specific to NetFlow; the correct service is the NetFlow service.

Exact Extract from Official Guide:

"If NetFlow collector service status is down:

Ensure the SolarWinds database is online and the server is not experiencing resource issues.

Use the Orion Service Manager to start or restart the NetFlow service.

If the issue persists, review the NetFlow logs for errors and consult the SolarWinds Success Center for advanced troubleshooting."— (Network Performance Monitor Administrator Guide, Troubleshooting NetFlow and Service Issues)
