# 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:

```bash
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:

| Active Replicas   | Active replicas for 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                                |                                                                                                    |
