zabbix-no-data

zabbix-no-data is a skill for Claude Code, Codex from stufently/zabbix-ai-cli-mcp. It costs 47 tokens per session (494 once invoked), scanned A, original, Apache-2.0.

A toolkit for finding Zabbix hosts and monitoring checks that have stopped reporting. Zabbix is a monitoring system that tracks servers, devices, and services, and the toolkit distinguishes connection failures from broken or silent checks.

In plain words
What is it for?
Use it to list unreachable hosts, investigate one host, or search recent metrics by name. It reports interface errors, maintenance state, unavailable agents, unsupported items, stale values, and how old each value is.
Why use it?
It helps explain whether missing data comes from an unreachable host, an unsupported check, a silent supported item, or maintenance settings. That prevents treating every period without data as the same problem.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

zabbix-no-data scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Zabbix: silence and no-data

Silence is ambiguous: a host that reports nothing looks the same as a host with nothing wrong. These commands tell the two apart.

Workflow

  1. Across the installation:

    zabbix-ai-cli-mcp unreachable --json

    Lists monitored hosts with an unavailable interface, with the error text Zabbix recorded and whether the host is in maintenance.

  2. For one host:

    zabbix-ai-cli-mcp host investigate web01 --json

    Read no_data_items and unsupported_items together with status.agent_available.

  3. For specific checks:

    zabbix-ai-cli-mcp metrics latest web01 --search disk --json

    Each value carries no_data, stale and age.

Distinguishing the causes

  • Agent unreachable — the interface is unavailable and carries an error. Nothing on that host is reporting; investigate connectivity, not individual checks.
  • Item unsupported — the check runs and fails. error says why: a missing binary, a permission problem, a changed key. This is a monitoring fault.
  • Item silent but supported — the check stopped producing values without erroring. Often a template or interval change.
  • In maintenance without data collection — the gap is expected. Check maintenance list before calling it a fault.

Reading the result

stale means the newest value is older than three collection intervals. It is only computed for items that collect on a schedule: trapper and dependent items arrive when something else sends or derives them, so silence from one is not a fault. Items with a flexible or scheduling interval fall back to a conservative threshold and are not flagged on thin evidence.

Do not

  • Do not read lastclock or lastvalue from a raw item.get. Both have returned a constant zero for several releases, which makes every item look silent.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
