 ClearML serving instances send serving statistics (count/latency) automatically to Prometheus and Grafana can be used 
 to visualize and create live dashboards.

 - login with: admin/admin
 - create a new dashboard
 - select Prometheus as data source
-- Add a query: `100 * delta(test_model_sklearn:_latency_bucket[1m]) / delta(test_model_sklearn:_latency_sum[1m])`
+- Add a query: `100 * increase(test_model_sklearn:_latency_bucket[1m]) / increase(test_model_sklearn:_latency_sum[1m])`
 - Change type to heatmap, and select on the right hand-side under "Data Format" select "Time series buckets"
 - You now have the latency distribution, over time.

 > **Notice**: If not specified all serving requests will be logged, to change the default configure "CLEARML_DEFAULT_METRIC_LOG_FREQ", for example CLEARML_DEFAULT_METRIC_LOG_FREQ=0.2 means only 20% of all requests will be logged. You can also specify per endpoint log frequency with the `clearml-serving` CLI. Check the CLI documentation with `cleamrl-serving metrics --help`
