dt-obs-network-devicesAnalyze SNMP-monitored network devices (switches, routers, firewalls, load balancers) in Dynatrace.
Dt Obs Network Devices is an agent skill from Dynatrace/dynatrace-for-ai. Analyze SNMP-monitored network devices (switches, routers, firewalls, load balancers) in Dynatrace. Three data layers: Smartscape topology (EXTNETWORKDEVICE / EXTNETWORKINTERFACE nodes, belongsto and calls edges); com.dynatrace.extension.networkdevice. metrics (CPU, memory, uptime, throughput, saturation, errors); and logs (SNMP traps, syslog, auto-discovery). Use to inventory devices, find down or saturated interfaces, check device CPU/memory/uptime, map topology and neighbors, detect interface errors, and…
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/logs.md`, `references/metrics.md` and `references/topology-model.md`).
It sits in DevOps & Cloud, covering Cloud networking. The repository describes itself as: Skills, prompts, and instructions for building AI agents on top of Dynatrace production context. The licence is Apache-2.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4f9aa71. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Dt Obs Network Devices loads about 2.1k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 253 tokens; SKILL.md has 811 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/dt-obs-network-devices/SKILL.md (or your agent's skills folder). This skill also uses 3 other files; get the full folder from GitHub.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.
SNMP extensions poll network hardware and expose it in Dynatrace as three layers:
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).com.dynatrace.extension.network_device.* namespace.This answers questions such as: Which interfaces are down? Which links are saturated? Is this router's CPU pegged? Which devices rebooted? What is connected to this switch? What traps has this device sent? What syslog errors are recurring?
| Layer | Query with | Grain | Key fields |
|---|---|---|---|
| Topology | smartscapeNodes "EXT_NETWORK_DEVICE" / smartscapeNodes "EXT_NETWORK_INTERFACE" | One row per device / interface (current inventory) | id, name, monitoring_mode, device_type, location, ip, speed, edges via belongs_to / calls |
| Metrics | timeseries … com.dynatrace.extension.network_device.* | Time series per device / interface | grouped by dt.smartscape.ext_network_device and (interface metrics) dt.smartscape.ext_network_interface |
| Logs | fetch logs | filter dt.openpipeline.source == "…" | Individual log records (traps, syslog, discovery) | joined to topology by expanding the device ip[] array and matching device.address / dt.ingest.source.ip — see references/logs.md |
The join key is the Smartscape ID. Every metric carries a dt.smartscape.ext_network_device dimension (and interface metrics also carry dt.smartscape.ext_network_interface). Use lookup [smartscapeNodes …] to attach human-readable device/interface names to metric results, and to attach live metrics to an inventory listing. Both reference files show this pattern.
Every device has a monitoring_mode. This is the first thing to check — it decides whether metrics exist at all:
monitoring_mode | Meaning | Has metrics? | Has full attributes? |
|---|---|---|---|
Extension | Directly polled by an SNMP extension | Yes — full com.dynatrace.extension.network_device.* set | Yes |
Discovery | Discovered on the network but not directly polled | No | Partial |
Neighbor | Known only because a polled device names it as an LLDP/CDP neighbor | No | Minimal (name, chassis MAC) |
If a device has no metrics, check its
monitoring_modebefore assuming a data gap — onlyExtension-mode devices are polled. When listing "monitored devices," excludeNeighbor(and usuallyDiscovery).
Network device monitoring is one part of Dynatrace network observability. Route elsewhere when the question is not about device/interface health or topology:
| The user wants… | Use |
|---|---|
| Traffic between entities, top talkers, conversations, connection health (the flows through the network) | dt-obs-network-flows — including NetFlow/IPFIX/sFlow that these same devices export |
| Host NIC throughput / packet drops on OneAgent-monitored hosts (not SNMP devices) | dt-obs-hosts → references/host-metrics.md |
| Service request rate, latency, error rate | dt-obs-services |
| Setting up or configuring an extension (this skill covers the resulting data model, not extension authoring) | dt-obs-extensions |
General Smartscape traversal syntax (traverse, smartscapeEdges, references[…]) | dt-dql-essentials |
Network devices vs. network flows. This skill answers "what is the state of the box and its ports" (SNMP device/interface health and topology).
dt-obs-network-flowsanswers "what traffic is crossing the network" (conversations, bytes, talkers). The same router appears in both: here as anEXT_NETWORK_DEVICEwith interface counters, there as a NetFlow exporter. A future macrodt-obs-networkskill may unify them; until then, cross-link.
EXT_NETWORK_DEVICE and EXT_NETWORK_INTERFACE node types with full field reference, monitoring modes, and the belongs_to / calls edges. DQL for device inventory (with filtering by mode/type/location/vendor), listing a device's interfaces, resolving an interface to its device, and mapping device/interface neighbor topology.com.dynatrace.extension.network_device.* metric catalog with units, dimensions, and field-typing rules. DQL for device health (top CPU, memory % with fallback, uptime and reboot detection) and interface health (down interfaces, throughput and saturation vs. link speed, error/discard counts, per-device interface detail), each joined to device/interface names.extension:com.dynatrace.extension.snmp-traps-generic), syslog (extension:syslog), and auto-discovery activity (extension:com.dynatrace.extension.snmp-auto-discovery). Covers the IP-to-Smartscape join pattern (device.address / dt.ingest.source.ip → snmp.ip), field references for all three sources, and DQL for recent traps with device names, trap frequency by OID, error syslog, top event patterns, combined per-device view, and LLDP/CDP neighbor discovery logs.© Dynatrace, Apache-2.0.
