Comprehensive and Detailed Explanation From Exact Extract:

SolarWinds NTA (and Hybrid Cloud Observability) supports a range of flow technologies including J-Flow (used by Juniper devices) and sFlow (an industry standard for network monitoring and traffic analysis). GFlow and HFlow are not supported flow technologies in SolarWinds' official documentation.

According to theSolarWinds Log Analyzer Administrator Guide (Version 2024.1), Log Analyzer provides several built-in or native log entry actions as part of its log-processing rules. The key native log entry actions include:

Add a tag to the log entry: This action allows you to tag event logs for easier searching and filtering later.

Continue rule processing but do not save: With this action, the log entry is not saved but rule processing continues.

Halt further rule processing for the log entry: Selecting this action will immediately stop the processing of any more rules for the current log entry.

Sending an email notification is an alert action and not considered a native log entry action in the context of log processing rules.

To monitor an application on a server with SolarWinds, you must first find the application in the list of available (supported or discovered) applications and enable monitoring for it. The platform also provides a “monitor recommended applications” button to automatically suggest and enable monitoring for best-practice applications on a given server.

From the documentation:

“To monitor an application, select it from the list of available applications and enable it for the target server. The ‘Monitor Recommended Applications’ option helps you quickly enable commonly used application monitors.”

Grouping IP addresses or configuring specific source/destination pairs is not required for standard application monitoring.

SolarWinds Hybrid Cloud Observability supports a wide range of flow technologies for IP traffic monitoring. Per the SolarWinds NPM Administrator Guide:

"SolarWinds supports NetFlow, sFlow, J-Flow, and IPFIX for monitoring traffic flows. These protocols are used by devices from different vendors to export flow information."

J-Flow: Used by Juniper devices and fully supported.

NetFlow (nFlow): The industry standard from Cisco and widely supported.

sFlow: A vendor-neutral flow technology supported by multiple devices.

IPF1X is not a recognized flow protocol in SolarWinds documentation.

Resolving and storing hostnames at the time a flow record is received means the platform does not need to resolve the hostname each time a report or widget is loaded, which:

Decreases database query times: Hostnames are already resolved, making queries for reports and dashboards much faster.

Flow views and widgets load faster: With DNS already resolved, the interface does not have to perform on-demand DNS lookups, reducing latency in the web console.

The SolarWinds documentation states:

"Immediate DNS resolution upon flow record ingestion reduces lookup delays during analysis and widget loading, resulting in improved performance and reduced query times."

Domain widgets and reports run with DNS names, but the core advantage is performance rather than widget availability.

Universal Device Pollers (UDPs) must be explicitly assigned to each node for which custom polling is required. Adding a new node does not automatically assign existing UDPs to that node, even if it’s the same device type as others already using the poller. Assigning the existing UDP to the new node will resolve the issue and enable polling of the desired data.

For secure syslog (Syslog over TLS), the standard port used is TCP 6514. SolarWinds Log Analyzer and Platform listen on TCP port 6514 for secure syslog messages.

Exact Extract from Official Guide:

"Log Analyzer supports receiving secure syslog messages over TCP port 6514, in accordance with the RFC 5425 standard."

A "no data" message in NetFlow charts usually indicates that the flow collector service is not receiving or processing flow data. One of the primary troubleshooting steps recommended in the SolarWinds documentation is to restart the collector service. This resolves issues caused by service interruptions, memory leaks, or flow processing errors.

The documentation states:

"If NetFlow charts display 'no data,' verify that the NetFlow collector service is running. Restart the collector service if necessary, as service interruptions can cause a lack of flow data display."
