## What it does

The skill covers three data layers in Dynatrace. Topology is the Smartscape inventory of `EXT_NETWORK_DEVICE` and `EXT_NETWORK_INTERFACE` nodes, with vendor, model, firmware, addresses and `belongs_to` / `calls` edges. Metrics live under `com.dynatrace.extension.network_device.*`: CPU, memory, uptime, throughput, saturation, errors. Logs carry SNMP traps, syslog messages and auto-discovery records.

The layers join on the Smartscape ID. Every metric carries a `dt.smartscape.ext_network_device` dimension, interface metrics also carry `dt.smartscape.ext_network_interface`, so `lookup [smartscapeNodes …]` attaches readable names to the numbers. The DQL itself sits in reference files, and the skill routes each question to the right one: inventory and topology, health and performance, or events.

Check `monitoring_mode` first. Metrics exist only in `Extension` mode, where an SNMP extension polls the device directly. Devices in `Discovery` or `Neighbor` mode have none, so an empty result there is expected rather than a data gap. Traffic between entities and top talkers belong to `dt-obs-network-flows`, and host NIC throughput to `dt-obs-hosts`.

```

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

### Codex

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

2. **Manually: put the files in place**
- File: `.agents/skills/dt-obs-network-devices/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/dt-obs-network-devices/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

gemini skills install https://github.com/Dynatrace/dynatrace-for-ai --path skills/dt-obs-network-devices
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/dt-obs-network-devices/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-obs-network-devices -a opencode
```

### 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-devices/SKILL.md

## When to use it
- inventory switches, routers and firewalls
- find interfaces that are down
- check CPU and memory on a single device
- map LLDP and CDP neighbors
- dig into recurring syslog errors and SNMP traps

## Example prompts
- List all SNMP devices in Dynatrace with monitoring mode Extension
- Which interfaces on the core router are down right now?
- What SNMP traps did this switch send in the last hour?

# Network Devices Skill

Analyze SNMP-monitored network infrastructure in Dynatrace — switches, routers, firewalls, load balancers, access points, and any other device polled by a **network device extension** (the SNMP-generic and vendor SNMP extensions). This skill covers the **device and interface data model** and routes each question to the right reference file. All DQL lives in the reference files and was validated against a live tenant with `dtctl query`.

## What Network Device Monitoring Tells You

SNMP extensions poll network hardware and expose it in Dynatrace as **three layers**:

- **Topology** — an inventory of devices and their interfaces as Smartscape nodes (`EXT_NETWORK_DEVICE`, `EXT_NETWORK_INTERFACE`), with attributes (vendor, model, OS/firmware, location, contact, IPs, MACs, link speed) and relationships (which interface belongs to which device; which devices are neighbors via LLDP/CDP).
- **Metrics** — time series for device health (CPU, memory, uptime) and per-interface health (operational/admin status, in/out throughput, errors, discards, packet mix), under the `com.dynatrace.extension.network_device.*` namespace.
```
