The skill
The loki skill covers Grafana Loki and the LogQL query language: stream selectors, line filters, parsers, metric queries, log ingestion and architecture.
Only when you ask.
The habit
Log errors spotted every hour.
↻ Runs by itselfevery hour
How the habit works.
You don't have to.
When does it start? How does it check its work? What does it remember?
One run, step by step.
Then it stops.
Stops after five queries per run, with one retry per query.
- 01
Select streams
Your agent starts each query with a label selector such as env="prod".
- 02
Filter early
It puts line filters like |= "error" first for speed.
- 03
Parse fields
It uses json, logfmt or pattern parsers to read status and duration.
- 04
Compute rates
It runs sum(rate(...)) by service and compares with offset 1h.
- 05
Find slow and 5xx
It lists requests with duration > 1s and status >= 500.
- 06
Log and flag
It writes the rates to the log and flags services above the threshold.
What it may do.
Nothing more.
It writes only in its own folder and asks you before anything goes out.
- Writes only inloops/loki-error-rate-loop/**
- Talks tono outside service
- Sendsnothing
- Your OKNothing goes out, so it needs no OK.
Is it for you?
Use it when it fits.
Read both lists. If the left one sounds like you, the Loki skill helps.
Use it when
- ✓ You write LogQL queries
- ✓ You build an error rate alert
- ✓ You set up log shipping with Alloy
Skip it when
- – You do not use Grafana Loki
- – You need full-text search across all log content
Loki skill, answered.
Why put line filters first?
Line filters are the first pipeline stage, and the skill places them first for performance.
What does Loki index?
Only the labels, not the full log text.
Can it help with ingestion too?
Yes. The skill also covers sending logs with Grafana Alloy, Promtail, Fluent Bit and the HTTP push API.
How do I install the Loki skill?
Copy the prompt at the top into your agent. It installs the skill from grafana/skills and sets up the habit. Or run npx skills add grafana/skills --skill loki.
Is the Loki skill free?
Yes. It is published under Apache-2.0. Habit is free too.
