SolarWinds Hybrid-Cloud-Observability-Network-Monitoring Online Access

Comprehensive and Detailed Explanation From Exact Extract:

To monitor a custom application using flow monitoring in SolarWinds Hybrid Cloud Observability, you must define the application by specifying its port or port range (and optionally protocol). After this, the application can be assigned to flows involving specific machines, but the primary step is to define application ports first.

NBAR2 (Next Generation Network-Based Application Recognition) is Cisco's deep packet inspection technology used to classify network traffic at the application layer. It provides visibility by inspecting packet payloads, not just ports, and is supported in SolarWinds for advanced application recognition.

SolarWinds documentation states:

"NBAR2 allows supported Cisco devices to classify traffic by application using deep packet inspection. This provides detailed application visibility within SolarWinds network monitoring solutions."

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.

SolarWinds provides several statistics for network capacity planning, most notably:

Memory usage data on nodes: Useful for forecasting resource exhaustion on network devices.

Receive utilization on interfaces: Essential for predicting bandwidth saturation and planning upgrades.

The documentation states:

"Key statistics for network capacity planning include interface utilization trends (receive and transmit) and memory utilization, which allow for forecasting and proactive infrastructure management."
