Universal Device Pollers (UDPs) are tied to the polling engine on which they are created. This means if a UDP is created on the main polling engine, it will only collect data for devices polled by that engine. To collect data from devices polled by an additional polling engine, you must create or assign the UDP on that engine as well.

Exact Extract from Official Guide:

“Universal Device Pollers are tied to the polling engine on which they are created. To monitor devices assigned to an Additional Polling Engine, the UDP must be created or assigned on that engine.”

A. When you probe less frequently, updates are slower but generally more accurate since there ' s less overhead and less chance of missing network changes due to polling overlaps.

C. Probing more frequently results in faster updates but may slightly decrease accuracy due to increased network noise and overlapping probes.

The documentation states:

" A higher probing frequency provides faster updates in NetPath views but can reduce accuracy due to more frequent sampling. Lower frequency means slower updates but typically results in higher accuracy and less system load. "

For a node-specific log view, navigate to the node’s details summary and choose “Analyze Logs” under the Management section. This provides a filtered view of log messages for the selected node, allowing you to drill into relevant log events and details.

From the documentation:

“To view logs for a specific node, open Node Details > Management > Analyze Logs for node-level log analysis and troubleshooting.”

When a device returns multi-core CPU statistics as a table, SolarWinds Device Studio allows you to use the " Add Calculated Value " option and select the average function. This enables the web console widget to display the computed average CPU utilization automatically.

The documentation explains:

" For devices with multi-core CPUs, you can use the Add Calculated Value feature in the Device Studio to compute the average (or other statistical functions) of returned table values, which can then be visualized directly in widgets. "

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.”

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.

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.

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.

To monitor and configure High Availability (HA) mode for site-to-site VPN tunnels on a Cisco ASA firewall, SolarWinds uses SNMP for standard device and interface metrics, and CLI polling for advanced VPN and HA state details. SNMP provides general health data, while CLI polling (using Device Studio or Network Insight) collects information not available via SNMP, such as detailed VPN and HA status.
