monkit-metrics

monkit-metrics is a skill for Claude Code from storj/claude-plugins. It costs 75 tokens per session (2,396 once invoked), scanned A, original, MIT.

A skill for reading Monkit Prometheus metrics from Storj Go services. Monkit records timing, call counts, failures, and concurrent work for instrumented functions; Prometheus is a system for storing and querying such metrics.

In plain words
What is it for?
Use it to investigate latency, throughput, error rates, and concurrency across services, pods, nodes, or regions, and to find which Go functions are instrumented.
Why use it?
It helps turn raw service metrics into answers about which functions are slow, how often they run, how many requests are active, and how often they fail.

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

monkit-metrics scanned grade A with 1 finding 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (compare-instances.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

This is the primary path — Thanos sits behind Grafana auth and direct `curl` won't work.

Monkit Prometheus Metrics

Overview

Monkit (defer mon.Task()(&ctx)(&err)) emits two metrics for every instrumented Go method:

  • function_times — latency (percentiles, min/max, recent samples). Use for "how slow?"
  • function — call counters and concurrency. Use for "how often?" / "how many in flight?" / "how many fail?"

Both share the same name, scope, and environment labels, so you usually query them with the same filter set.

function_times — latency

Structure

function_times{name="...", field="...", kind="...", scope="...", ...}
Label Values Notes
name __Receiver__Method or bare func name See naming below
field see field table Most useful: r99, recent
kind success, failure Failure r99 can be 100×+ success r99 — always filter
scope package import path with /_ e.g. storj_io_storj_satellite_metainfo

Values are in seconds — multiply by 1000 for ms.

field values

Field Meaning
count, sum, min, max Cumulative since process start
r10, r50, r90, r99 Percentile latency (rolling reservoir)
rmin, rmax, ravg Min/max/avg over the rolling window
recent Most recent observation

function — call counters & concurrency

Same name/scope/env labels as function_times. No kind label — outcomes are encoded in field.

field values

Field Kind Meaning How to query
total counter All invocations rate(...[5m]) = total QPS
successes counter Non-error returns rate(...[5m]) = success QPS
failures counter Error returns rate(...[5m]) = error rate
errors counter Same as failures in current monkit
panics counter Go panics caught by monkit rate(...[5m]) — should be ~0
count counter Completed invocations rate(...[5m])rate(total[5m])
current gauge In-flight invocations right now Read as-is
highwater gauge Peak current ever seen Read as-is
delta counter-ish Completions since last sample Rarely useful — prefer rate(total)

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.

monkit-metrics is a skill published in the GitHub repository storj/claude-plugins (3 stars, last pushed 3mo ago), licensed MIT. It adds 75 tokens to every session and 2,396 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
