At a glance

Device availability and monitored inventory from Zabbix — is a device reachable, since when, how often has it flapped, and what is the NMS actually watching.

  • Works in 6 steps: Never say "the device is down." Say what… → Always timestamp the observation. → Not monitored ≠ unreachable. Check… → …
  • Someone asks how long a device has been down
  • SKILL.md covers Server, ⚠ The wording rule — this is…, Four states, not two and Always carry the time, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Zabbix Availability is an agent skill from automateyournetwork/netclaw. Device availability and monitored inventory from Zabbix — is a device reachable, since when, how often has it flapped, and what is the NMS actually watching. Use when someone asks how long a device has been down, whether it is flapping, or what is and is not being monitored.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: An AI agent that claws through your network. The licence is Apache-2.0.

When your agent uses it

  • Someone asks how long a device has been down
  • Whether it is flapping
  • What is and is not being monitored

Example prompts

  • “/zabbix-availability”

Requirements

  • A credential in ZABBIX_TOKEN

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Never say "the device is down." Say what Zabbix observed, and when.
  2. Always timestamp the observation.
  3. Not monitored ≠ unreachable. Check before you conclude.
  4. Report flap counts, not just current state.
  5. Show disabled hosts. Omitting them hides the gap.
  6. Read-only.

What it can do on your machine

Read from SKILL.md and the folder at commit 95bb17e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are jsonc).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Zabbix Availability loads about 1.2k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 541 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Safety

Auto-check passed

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.

Zabbix Availability & Inventory

Server

zabbix-mcp — vendored third-party, read-only, three tools. See zabbix-metrics-history for the shared cautions.

⚠ The wording rule — this is the whole skill

"Zabbix cannot reach it" is not "the device is down."

An NMS reports what one poller saw, from one vantage point, at one polling interval. That is evidence, not a verdict.

A device can be unreachable from Zabbix and completely healthy: a firewall rule, a management-VRF problem, a dead SNMP daemon on an otherwise forwarding router, or a poller that has simply not tried recently.

Never write "the device is down." Write:

"Zabbix has been unable to reach rtr-01 since 14:02 UTC. That is the monitoring system's view from its own vantage point — it is not confirmation the device is down. pyats or multivendor-cli can check the device directly."

This is the same discipline globalping-external-checks applies to probes, and it matters more here, because an NMS feels authoritative in a way a probe network does not.

Four states, not two

StateavailableSay
Reachable1"Zabbix reached it at <time>"
Unreachable2"Zabbix cannot reach it as of <time>" — never "it is down"
Unknown0"Zabbix has not yet established reachability" — not the same as unreachable
Not monitoredhost absent"this device is not monitored by Zabbix" — not the same as unreachable, and by far the most common cause of surprise
jsonc
zabbix_api("host.get", {
  "output": ["hostid","host","name","status"],
  "selectInterfaces": ["interfaceid","ip","dns","port","available","error","errors_from"],
  "selectTags": "extend"
})

Always carry the time

Availability without a timestamp is a claim about the present that may be minutes or hours stale. Every answer states when that state was last observed. errors_from gives you when the failure began.

Down vs flapping — different problems

"It has been down for 40 minutes" and "it has bounced nine times in 40 minutes" lead to completely different investigations. Get the transitions, not just the current state — event.get against the unreachability trigger gives you the history.

Report the count of transitions as well as the current state whenever the window contains more than one.

Inventory — what is the NMS actually watching?

jsonc
zabbix_api("host.get",      {"output":["hostid","host","status"], "selectInterfaces":"extend",
                             "selectParentTemplates":["name"], "selectHostGroups":["name"]})
zabbix_api("hostgroup.get", {"output":"extend"})
zabbix_api("item.get",      {"hostids":["<id>"],
                             "output":["itemid","name","key_","value_type","units","history","trends","lastclock"]})

Two rules:

  • A disabled host (status: 1) is shown as disabled, never omitted. A device nobody is watching is a finding, not an absence — it is usually how a gap in monitoring is discovered.
  • List items with their units and retention (history, trends). This lets an engineer see how far back a question can be answered before they ask it, which is far better than asking and getting nothing.

An item whose lastclock is empty is monitored but has never returned a value — a broken poll, and a real finding. Do not report it as "no data".
