How to evaluate Network Performance Monitoring

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Flowmill. It comes from our Network Monitoring & Management buyer guide.

25%

Visibility Across Unowned Paths

Hop-by-hop internet and WAN path analysis across ISP and cloud backbones, SaaS and API reachability, BGP route monitoring, and a global vantage-point network for synthetic tests from where users actually sit

25%

Owned-Estate Depth (Device, Flow, Config)

Multi-vendor SNMP and streaming-telemetry coverage, auto-discovery and live topology mapping, NetFlow/sFlow/IPFIX and eBPF flow analytics, and configuration backup, change tracking, and compliance

20%

Experience & Correlation (DEM + AIOps)

Digital-experience scoring tied to network health, anomaly detection on streaming telemetry, alert deduplication and noise reduction, automated root-cause grouping by topology, and one timeline from path to service

15%

Cloud & Hybrid Coverage

AWS/Azure/GCP VPC and VNet flow logs, cloud-provider API ingestion, SD-WAN and SASE fabric visibility, container and service-mesh network paths, and unified hybrid view rather than a separate cloud silo

10%

Observability & Workflow Integration

Correlation with APM/infrastructure/logs, ITSM and incident routing (ServiceNow, PagerDuty), SIEM/SOAR hooks, OpenTelemetry support, and open API/IaC coverage for automation

Operating Model & Cost Fit

SaaS vs. self-hosted, agent/collector footprint to deploy and patch, multi-tenancy for MSP or shared-services use, and whether the licensing unit (device, sensor, host, flow, agent) scales with your estate predictably
