## What it does

This skill handles questions metrics and traces cannot: who talks to whom, which entities push the most traffic, which connections reset, and what the round-trip time looks like. It sits on top of three Dynatrace flow sources. OneAgent flows capture host, process and pod connections to peers as events in the `default_network_flows` Grail bucket. NetFlow, IPFIX and sFlow come from network hardware and land in logs through an OpenTelemetry Collector. Cloud flow logs cover AWS VPC and Transit Gateway; Azure and GCP are planned.

Routing is the point. The skill decides which source a question belongs to and pulls the reference file with the matching DQL. When a flow shows up in two sources at once, the one with richer entity context wins, and that is usually OneAgent. For cloud logs the author recommends a dedicated bucket instead of mixing them into a shared one.

The boundaries are explicit. Host NIC throughput and packet drops belong to `dt-obs-hosts`, service request rate and latency to `dt-obs-services`, synthetic uptime monitoring to `dt-obs-ext-monitors`. This one is about flows, and it will not stand in for the rest. Resolving a raw IP back to a monitored entity lives in a shared reference file used by both OneAgent flows and NetFlow.

## Requirements

```

2. **Manually: put the files in place**
- File: `~/.claude/skills/dt-obs-network-flows/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/dt-obs-network-flows/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-network-flows -a codex

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Dynatrace/dynatrace-for-ai/tree/HEAD/skills/dt-obs-network-flows/SKILL.md

## When to use it
- find the hosts generating the most traffic
- map dependencies between pods and external endpoints
- work out why a connection resets or times out
- measure retransmission share and RTT for one conversation
- resolve a raw IP:port to a monitored host, process or service

## Example prompts
- show me the top talkers by bandwidth for the last hour
- which pods talk to external endpoints, and on which ports
- dig into the connection resets between these two hosts

  Network flow analysis in Dynatrace across three sources: OneAgent flows
  (host/process/pod-to-peer connections in the `default_network_flows` Grail
  bucket), NetFlow/IPFIX/sFlow (via an OpenTelemetry Collector), and cloud flow
  logs (AWS VPC / Transit Gateway; Azure and GCP planned). Use to analyze traffic
  between entities, find top talkers by bandwidth, map communication dependencies,
  investigate connection health (resets, timeouts, retransmissions, RTT), and
  resolve peers to monitored entities. Routes each question to the right source;
  source-specific DQL lives in the reference files.
  Trigger: "network flows", "top talkers", "traffic between hosts", "connection
  resets", "TCP retransmissions", "RTT", "pod connections", "network dependencies",
  "NetFlow", "IPFIX", "sFlow", "VPC flow logs", "cloud network traffic".
  Do NOT use for host NIC throughput or packet drops (use dt-obs-hosts), service
  request rate or latency (use dt-obs-services), or synthetic/uptime monitoring
  (use dt-obs-ext-monitors).

# Network Flows Skill

Analyze network traffic in Dynatrace across three flow data sources. This skill covers the **use cases** network flows enable and routes each question to the right source and reference file. The detailed, source-specific DQL lives in the reference files.

## What Network Flows Tell You

Network flow data answers questions that metrics and traces cannot:

- **Who talks to whom** — communication dependencies between hosts, processes, pods, services, and external endpoints
- **Top talkers** — which entities generate the most traffic, by bytes or connection count
- **Connection health** — resets, timeouts, retransmissions, and round-trip time (RTT) per conversation
- **Traffic composition** — protocol (TCP/UDP), destination ports, direction (client vs server)
- **Peer resolution** — mapping raw IP:port peers back to monitored entities (host, process, pod, service) or flagging them as external

---

## The Three Flow Sources

Choose the source based on **where the traffic is** and **what is capturing it**. When more than one applies, prefer the source with the richest entity context (usually OneAgent).

| Source | Captured by | Data location | Entity context | Use when |
|---|---|---|---|---|
