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.

caution

If you do not see the Settings page you're looking for, you likely don't have the proper permissions and need to contact your admin.

SLOs​

Entity 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
FieldDescription
streamIdID of your Lightstep stream, which can be found in Lightstep, through the URL. https://app.lightstep.com/{org}/stream/my-stream/{streamId}
percentilePercentile latency for your given streamId, out of 1
targetLatency targets in ms. Latency is currently the only target supported
sloSLO percentile, out of 1
