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

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

Metrics in the dashboard

Panel	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
