Netronome is a self-hosted network monitoring platform that runs scheduled internet speed tests, watches packet loss and DNS resolvers, and reports bandwidth and health data from every server you point it at. Run tests against Speedtest.net, your own iperf3 servers, or public and custom LibreSpeed servers, choosing the exact endpoint from a list sorted with the nearest first. Put tests on a recurring schedule and read the history charts to catch an ISP that sags every evening or a connection that never delivers the speed on the invoice. Install the companion agent on each machine and watch live upload and download rates, traffic by hour, day, and month, processor and memory load, disk space, and temperatures in one place. Trace routes hop by hop, keep packet loss percentages in view, and confirm your DNS resolvers answer fast and return the records you expect. Set thresholds for download and upload speed, ping, packet loss, disk space, CPU, memory, and temperature, and route alerts to Discord, Telegram, Slack, email, ntfy, Gotify, Pushover, or a webhook. The server, the web interface, and the agent ship as one program, and agents connect over HTTP with an optional API key or inside a Tailscale network.

Holding internet service providers accountable for promised bandwidth requires continuous, automated measurement, and MySpeed turns any server into an always-on connection performance analyzer that tracks download speeds, upload throughput, ping latency, and jitter around the clock. Instead of running manual browser tests only when video calls stutter, you can schedule recurring speed checks using custom Cron expressions and switch freely between Ookla, LibreSpeed, and Cloudflare testing servers to verify routing performance across different upstream networks. Interactive statistics views render gradient speed timelines, ping and jitter graphs, hourly performance breakdowns that expose peak-hour congestion, and standard deviation consistency charts, using smart 300-bucket downsampling so multi-month histories load instantaneously. Failed tests are flagged with visual markers on the timeline, while built-in health checks dispatch instant alerts to Discord, Telegram, Signal, WhatsApp, Gotify, email, or custom webhooks whenever bandwidth drops below your target thresholds or outages occur. Administrators can link multiple remote MySpeed instances into a single dashboard to compare bandwidth across branch offices, pause scheduled runs during heavy file transfers, export historical logs, and scrape real-time telemetry into Prometheus and Grafana.

Monitoring everything from network switches to Kubernetes clusters since 2001 with over 6,200 GitHub stars and deployments exceeding 100,000 devices per installation, Zabbix has established itself as one of the most mature and feature-rich open-source monitoring platforms available, trusted by organizations including Dell, Salesforce, ICANN, and T-Mobile. The platform collects metrics from virtually any source using Zabbix Agent written in C, Zabbix Agent 2 written in Go with native plugin support, SNMP v1/v2c/v3 polling and trapping, IPMI for hardware health, JMX for Java applications, SSH and Telnet checks, HTTP/HTTPS polling, and ODBC database queries. Version 7.0 LTS introduced synthetic browser monitoring that executes user-defined JavaScript via WebDriver to simulate multi-step user interactions on websites, proxy load balancing with automatic host redistribution across proxy groups for high availability, in-memory proxy data buffering delivering up to 100x performance improvement, native multi-factor authentication with TOTP and Duo support, and just-in-time user provisioning from SAML and LDAP. Low-level discovery automatically detects file systems, network interfaces, SNMP OIDs, VMware resources, and Kubernetes pods, creating monitoring items and triggers dynamically. The alerting engine correlates events with configurable escalation chains, sending notifications through Slack, Microsoft Teams, PagerDuty, Jira, email, and SMS with customizable message templates. Over 1,000 official templates provide instant monitoring for Linux, Windows, VMware, AWS, Azure, Docker, PostgreSQL, MySQL, Apache, Nginx, and hundreds more.

Network traffic stops being a mystery once ntopng names the hosts, applications, and protocols behind every flow, live in your browser. To find the host saturating an uplink, open the dashboard, which ranks top talkers, countries, autonomous systems, and protocols beside historical charts. To see what a suspicious host is contacting, open its page for traffic, ports, DNS queries, TLS details, and visited sites, plus a map of its conversations. Deep packet inspection recognizes applications such as Facebook, YouTube, and BitTorrent, so charts name the app behind the bytes instead of relying on port numbers alone. The console reads packets from a SPAN port or TAP and NetFlow, sFlow, or IPFIX records from routers and switches through nProbe, so it can cover a single switch or many remote sites. Behavioural checks raise alerts for flows, hosts, and interfaces and send them to email, Discord, Telegram, or webhooks. Active monitoring probes remote hosts over ICMP and HTTP/S, and network discovery lists the devices on your local network. A REST API and Lua scripting pull statistics into your own tools and add custom checks.

Trusted by millions of engineers and deployed on over 80,000 GitHub stars worth of community confidence, Netdata delivers true real-time monitoring at per-second granularity — 10-60x faster than Prometheus, Datadog, or any conventional monitoring stack that averages away the transient anomalies lasting 2-10 seconds where most production incidents originate. A single installation command deploys the agent with zero configuration, automatically discovering every running process, container, systemd service, network connection, disk, and application on the host within seconds. Unsupervised machine learning trains multiple models per metric directly at the edge, detecting anomalies without thresholds, baselines, or manual tuning. The distributed Parent-Child architecture scales horizontally from a single Raspberry Pi to fleets exceeding 100,000 nodes while maintaining sub-2-second visualization latency and storing metrics at approximately 0.5 bytes per sample through tiered compression. Native network monitoring provides live topology maps, NetFlow and sFlow analytics, SNMP device polling across 200+ profiles, and trap handling — capabilities that typically require a separate NPM product. Hundreds of pre-configured alerts cover systems and applications out of the box, with AI-powered root cause analysis surfacing correlated metrics through natural language via MCP-compatible AI assistants. The agent supports Linux, macOS, FreeBSD, Kubernetes, and Docker with eBPF-based kernel observability requiring no application instrumentation.

Netra watches your network from the side, plugged into a switch mirror port, and turns everything it sees into a live picture of your traffic without ever sitting in the forwarding path. A single binary loads its eBPF collectors in the kernel, so aggregation happens before packets reach user space and multi-gigabit mirror feeds stay observable instead of dropping samples. The dashboard opens on totals, protocol share, and traffic trends, then lets you drill into flows by address, port, domain, or service, check which countries your traffic talks to on a world map, and read the internal topology as a live graph. Domains surface passively from TLS handshakes, public addresses are enriched with country and organization data, and heuristic detectors flag scanning, flooding, and single-host surges, pushing alerts to your team chat with an optional AI-written explanation. You can ask the built-in assistant questions about real recorded history, connect external MCP servers so it can call your own tools while it answers, and stream flows onward to Kafka for other consumers. History rolls into compressed columnar files on a schedule and stays queryable for a month by default.

Self-hosted and account-free, LAN Sheriff watches where your devices send their traffic, plots each destination on a live world map, and flags anything that looks suspicious. Click a destination on the Watchtower for its country and city, owning organization, reverse DNS, protocol, port, byte counts, duration, and responsible app or device; filter by device, app, country, organization, or protocol, or scrub back through history. Radio Chatter streams the DNS lookups it can see, surfaces first-seen domains, and labels tracker, ad, telemetry, and malware domains without ever blocking them. The Precinct Map diagrams observed traffic, while the Roster inventories every device by IP, MAC, manufacturer, hostname, inferred type, and services, and alerts you when an unrecognized one joins. The Wanted List applies eight rules, including beaconing, machine-generated domains, port scans, plaintext credentials, and volume anomalies, and explains each finding in a plain sentence rather than a mystery score. Deputy Mode needs no privileges and names the application behind each connection, while Patrol Mode adds packet capture for DNS lookups and traffic volumes. Pair installations with a code to widen your view, export any view as CSV or JSON, and send alerts to webhook, ntfy, Discord, or Slack.

TapMap draws a computer's live network connections on an interactive world map, so you can watch which applications are talking to which services, where those services sit, and what normal looks like for that machine. A local pipeline scans active sockets, extracts the remote addresses, and enriches them with geolocation from databases stored on the machine itself. Every connection carries the owning application or process, its network operator, and the operating system's verification status for that app, and places that share a location are highlighted when connections overlap. The same view lists local open ports, both TCP listeners and bound UDP sockets, established services on your LAN, and public services whose location could not be mapped. A rolling 30-day history turns raw connections into awareness: an Insights panel surfaces new applications, providers, countries, and ports, plus the most frequent activity, while a Significant Connections log records first sightings and failed verifications. A Daily Activity Report goes further, sorting applications into seen-once, occasional, recurring, and stable patterns, analyzing provider concentration, and charting country activity with detailed timelines. New significant connections can raise a desktop notification or publish to an MQTT broker you configure. Nothing is sent anywhere by default: processing happens locally, with no telemetry.

NetMap answers the four questions every homelab owner asks in four different tools: what is on my network, what address did it get, is it still up, and why is the firewall shouting about it. Devices you add appear automatically on a visual canvas where you can drag them into place, draw the links between them, and group them into VLANs or separate sites, and the layout is still there when you come back. Behind the map, every device is watched continuously: ping times graphed over history, service checks on the ports you care about, a heartbeat strip that betrays intermittent dropouts, and an uptime percentage that settles arguments. Address management stops being a spreadsheet: define subnets, import the leases your router already handed out, see used and free addresses as a grid, and get warned before a duplicate assignment causes a mysterious outage. Firewall logs stream in live and each entry links to the device it concerns, ready to search by address, port, or protocol. When something new appears, a network scan discovers hosts with their names, hardware addresses, and open ports for review before they join the inventory.

Your router calls it "Unknown device" at 192.168.1.23; Vedetta calls it the kitchen light and shows its work. Vedetta is a Home Assistant app that scans your local network, identifies what each device actually is, and explains every identification. One scan lists every device it can find with presence and latency history, in tile or list view, light or dark, on a computer or a phone. Behind each name sits the recognition engine: it weighs many weak clues together, counts a repeated fact once, groups devices by family, and shows certainty honestly, keeping anything doubtful in Other rather than inventing a label. Tap the info marker beside a name, brand, or type and a pop-up lists every clue, its weight, and the hypotheses that were rejected. Names or rooms you set by hand are never overwritten by later scans, and sleeping phones are remembered instead of flickering in and out. Choose from three search levels depending on how hard you want it to probe, let the nightly deep search refresh the picture, and use the network doctor to spot duplicate addresses, repeated restarts, devices that drop together, or a slowing gateway. It can also publish what you choose to Home Assistant and MQTT, display devices from other networks your Home Assistant already sees, and mask exports before they leave the machine.

Servers, services, and network gear report their health to Icinga 2, the open-source monitoring core that runs checks, evaluates thresholds, and decides who gets woken up. A distributed hierarchy of master, satellite, and agent zones scales from a single box to global estates: satellites execute checks in remote regions and keep working when the master is unreachable, while agents run local checks under TLS-secured, certificate-based trust. The object-based configuration language defines hosts, services, dependencies, and notification rules as code, with apply rules generating checks across whole groups automatically. Performance data streams into Graphite, InfluxDB, or Elasticsearch writers, and Icinga DB carries runtime state and history into Redis and SQL for the web frontends. The REST API drives acknowledgements, downtimes, and check scheduling from scripts and chat tools, with fine-grained permissions down to diagnostic information. The 2.16 line hardens API security, streams richer runtime updates to Icinga DB for the new Icinga Notifications 1.0 incident workflows, and lets operators set exact acknowledgement times through the API.

Watching a MikroTik RouterOS v7 router in real time is what MikroDash is for: live traffic, connections, Wi-Fi clients, DHCP leases, and WireGuard peers reach the browser the moment anything changes. Cards drag into any layout, and the arrangement follows your account to every browser. Managing a fleet happens on the Devices page, which shows routers as cards, a list, or a world map with 24-hour connectivity, last backup, open alerts, and pending updates. Rolling out a change starts in Config Management: choose one of 20 ready-made templates or capture your own, then deploy to one router or the fleet with a restore point, a canary router, and an automatic revert if a change cuts MikroDash off. Scheduled backups are kept only when something changed, with a diff and a guarded restore. New sites join through a generated script that calls home over a built-in WireGuard tunnel, even from behind NAT. Alerts reach SMTP, Telegram, ntfy, Discord, Slack, Gotify, Pushover, and Apprise. Troubleshooting stays in the browser with ping, traceroute, torch, bandwidth tests, a packet sniffer, and a RouterOS terminal. Read-only API access covers every page and alert, while roles, OpenID Connect sign-in, and an audit trail of every write govern shared use. Off by default, an optional assistant answers from live router data and asks before changing anything.

VyManager puts every VyOS router you run, across every site, into one web control plane with live dashboards and per-site permissions. Organize instances into logical sites, from the datacenter core to the smallest branch office, and add or remove routers without touching a command line. Live dashboards stream interface counters, system information, network graphs, and WireGuard peer status, so a saturated link announces itself before your users do. Configuration adapts to each router's VyOS version, with 1.4, 1.5, and rolling releases supported side by side during the longest upgrade cycle. Access is granted per site with OWNER, ADMIN, and VIEWER roles, API keys authenticate the machines, and SSH credentials stay encrypted at rest. A setup wizard walks a fresh deployment to its first managed router, and light, dark, and custom themes keep the night shift comfortable. For automation, AI assistants can be connected through the companion MCP integration, and the whole stack arrives as Docker Compose services you can redeploy in minutes.

Point your routers at Akvorado and every NetFlow, IPFIX, and sFlow record crossing your network becomes a chart you can interrogate. The web console opens on a live summary of flows per second, exporter count, and traffic split by autonomous system, port, protocol, country, and address family. From there, the visualize page turns stored flows into stacked, line, grid, and heatmap time series, plus Sankey diagrams that show how traffic moves between networks, interfaces, and countries. Filters use a simple SQL-like syntax, so a question like which customers pulled traffic over a transit link last night becomes a query, not a support ticket to your future self. Because the outlet polls each exporter with SNMP or gNMI, flows arrive wearing real interface names, descriptions, and speeds instead of raw ifIndex numbers nobody can read. GeoIP lookups attach country and city to addresses, classification rules tag providers, peers, and connectivity types, and optional BMP sessions add AS paths and BGP communities to every flow. Retention is tiered: raw flows keep full detail for recent days while one-minute, five-minute, and hourly rollups stretch summaries across a year of history. A Grafana plugin is available too, so the same flow data can sit on the dashboards your team already watches.
