Metrics

The cortex get and cortex get API_NAME commands display the request time (averaged over the past 2 weeks) and response code counts (summed over the past 2 weeks) for your APIs:

cortex get
env api status up-to-date requested last update avg request 2XX
cortex iris-classifier live 1 1 17m 24ms 1223
cortex text-generator live 1 1 8m 180ms 433
cortex image-classifier-resnet50 live 2 2 1h 32ms 1121126

The cortex get API_NAME command also provides a link to a Grafana dashboard:

Description

Note

Request Rate

Request rate, computed over every minute, of an API

In Flight Request

Active in-flight requests for an API.

In-flight requests are recorded every 10 seconds, which will correspond to the minimum resolution.

Active Replicas

Active replicas for an API

2XX Responses

Request rate, computed over a minute, for responses with status code 2XX of an API

4XX Responses

Request rate, computed over a minute, for responses with status code 4XX of an API

5XX Responses

Request rate, computed over a minute, for responses with status code 5XX of an API

p99 Latency

99th percentile latency, computed over a minute, for an API

Value might not be accurate because the histogram buckets are not dynamically set.

p90 Latency

90th percentile latency, computed over a minute, for an API

Value might not be accurate because the histogram buckets are not dynamically set.

p50 Latency

50th percentile latency, computed over a minute, for an API

Value might not be accurate because the histogram buckets are not dynamically set.

Average Latency

Average latency, computed over a minute, for an API
