# observability-service-reliability

Guides you from picking an SLI to running SLOs in Elastic Observability through the Kibana API. Useful when alerts are noisy and the error budget does not add up.

## What it does

The skill starts before any API call. It asks what a user or downstream consumer would actually notice. If the answer is a resource number — disk at 90%, heap climbing, replica lag — that is a capacity ceiling, and the skill routes it to a threshold rule instead of an SLO.

From there it works in Kibana: creating, verifying, updating, resetting, disabling and deleting SLOs, plus attaching burn-rate rules with fast-burn and slow-burn windows wired to different severities. Everything runs through the `elastic` CLI, so install it first — the skill tells you not to guess credentials or call the HTTP API directly. You need Kibana 8.x or 9.x with a matching Elasticsearch cluster and the Observability solution enabled. Cluster nodes must carry both the `transform` and `ingest` roles, since every SLO is backed by a continuous transform. Synthetics SLIs also need the Synthetics app and at least one configured monitor location.

A second thread is alert hygiene: drop duplicate coverage, snooze instead of disabling, delete rules nobody can act on. The skill insists you verify field names against the mapping before writing them into an indicator. Zero events means missing data, not a healthy service — a ratio over zero total events is undefined, not 100%.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill observability-service-reliability -a claude-code
```
```bash
npx skills add elastic/agent-skills --skill service-reliability -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill service-reliability -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill service-reliability -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install elastic/agent-skills service-reliability
```

2. **Manually: put the files in place**
- File: `.github/skills/service-reliability/SKILL.md`

2. **Platform CLI**
```bash
gemini skills install https://github.com/elastic/agent-skills --path skills/observability/service-reliability
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill service-reliability -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/elastic/agent-skills/tree/HEAD/skills/observability/service-reliability/SKILL.md

## When to use it
- route a reliability complaint to the right instrument
- pick an SLI type that fits the data you have
- set a target and window the measured history can support
- create and update SLOs through the Kibana API
- attach burn-rate rules to different severities

## Example prompts
- Help me pick an SLI and a target for our public API, we have a month of history
- Create an SLO for the checkout endpoint and attach a burn-rate rule
- Our availability alerts are noisy — work out what is redundant

  Design and operate service reliability targets in Elastic Observability: choose
  an SLI type and a defensible target, pick a time window and budgeting method, create
  and maintain SLOs through the Kibana API, attach burn-rate alert rules, and decide
  when an SLO is the wrong instrument and a threshold rule, anomaly job, or synthetics
  monitor is right. Use when defining or reviewing SLOs and error budgets, tuning
  burn-rate alerting, reducing alert noise, or setting up availability monitoring
  for a user-facing endpoint.
compatibility: >
  Requires Kibana 8.x or 9.x with a matching Elasticsearch cluster (self-managed,
  Elastic Cloud Hosted, or Serverless) and the Observability solution enabled. The
  cluster must have nodes carrying both the `transform` and `ingest` roles, since
  every SLO is backed by a continuous transform. Needs the `elastic` CLI >= 0.2 with
  `stack kb` and `stack es` support. Synthetics SLIs additionally require the Synthetics
  app and at least one configured monitor location.

# Service Reliability

Design reliability targets that people will actually act on, then operate them. This skill covers the judgment before
the API call — which service-level indicator fits the data you have, what target is achievable rather than aspirational,
whether an SLO is even the right instrument — and then the mechanics of creating, alerting on, resetting, and retiring
SLOs through the Kibana API.

Reliability instruments are not interchangeable. An SLO measures a user-visible outcome against a spendable budget; a
threshold rule fires on a raw condition; an anomaly job finds deviations where no fixed threshold exists; a synthetics
monitor is the only one of the four that can see a service that has stopped emitting telemetry entirely. Choosing wrong
produces alerts that are technically correct and operationally useless. For diagnosing a service that is already
degraded, and for the incident workflow itself, use the **observability-sre-triage** skill; for general rule lifecycle
mechanics use the **kibana-alerting-rules** skill.
