If interfaces on a node show an “unknown” status, the recommended solution is to delete and rediscover the node. This ensures all current interface information, OIDs, and properties are correctly detected and polled, resolving mismatch or missing data that can cause an “unknown” status.

When monitoring F5 BIG-IP load balancers, SolarWinds Network Insight requires both SNMP for device status and iControl (a proprietary F5 API) for advanced configuration and health monitoring. The SolarWinds guide states:

"After adding an F5 load balancer with SNMP, configure the iControl connection to access additional F5-specific health and configuration metrics."

The best practices for creating a Universal Device Poller (UDP) in SolarWinds are:

Consult vendor documentation for OID: Always check the device/vendor documentation for the correct OID to monitor the desired metric.

Perform SNMPwalk to determine if OID exists: Use SNMPwalk to verify the OID’s existence and see if it is supported and returns the correct values from the device.

Calling SolarWinds support is not a standard step for obtaining OIDs, and WBemtest is a Windows tool for WMI, not SNMP/OID polling.

Exact Extract from Official Guide:

“Consult device vendor documentation for correct OIDs and perform SNMPwalk to ensure the OID exists and is supported by the device before creating a UDP.”

To combine two polled values into a single value in the web console, you need to:

Create a separate poller for each OID.

Use a transform (in the UDP tool) to add or otherwise combine the values from the two pollers into one displayed value.

SolarWinds Log Analyzer supports secure syslog forwarding using the TCP protocol. The industry standard and the default port used for secure syslog (Syslog over TLS/TCP) is port 6514. This is referenced in SolarWinds documentation where it specifies:

"For secure syslog forwarding, Log Analyzer uses TCP port 6514, which is the default for syslog over TLS, as defined by RFC 5425."

This ensures that log data is encrypted during transmission, enhancing security over the default UDP port 514 (which is used for non-secure syslog).

This message means the NetFlow collector is receiving flow data from a device whose IP address is not managed in the SolarWinds platform, so the flow data is discarded. To resolve this, you must either:

Add the sending device as a managed node using the correct IP address, or

Enable the "Allow matching nodes by another IP" option in the NetFlow settings, which allows SolarWinds to match flows sent from an interface IP or secondary IP.

If a device studio poller is configured with a static textual value (rather than a dynamic OID), any change in the actual value on the node will not be detected automatically; the poller’s configuration must be manually updated to reflect the new value. OID-based pollers update automatically as values change on the device.

When the SolarWinds Log Analyzer web console is in "live mode," it automatically refreshes the log viewer data every 10 seconds by default, ensuring users see near real-time event streams.

The documentation states:

"In live mode, Log Analyzer refreshes data every 10 seconds to display the most recent events as they arrive."
