Lightstep

CatalogScorecards

Summary

Lightstep provides observability. You can use Lightstep to drive insights into values such as:

• SLOs
• Latency and error rate metrics

Setup

In order to connect Cortex to your Lightstep instance, you’ll need to create a Lightstep API Key, and add it under Settings → Lightstep.

SLOs

Service Descriptor

You can create and manage SLOs by listing relevant latency SLIs through Streams. Cortex will pull data from Lightstep, and track against your specified SLO. For example:

x-cortex-slos:
  lightstep:
    - streamId: sc4jmdXT
      targets:
      latency:
        - percentile: 0.5
          target: 2
          slo: 0.9995

Field	Description
streamId	ID of your Lightstep Stream, which can be found in Lightstep, through the URL. https://app.lightstep.com/{org}/stream/my-stream/{streamId}
percentile	Percentile latency for your given streamId, out of 1
target	Target latency, in ms
slo	SLO percentile, out of 1
