 After the metrics are onboarded to Metrics Advisor, the system will try to perform statistics on the metrics to categorize **anomaly pattern** types and **series value** distribution. By providing this functionality, you can further fine tune the configuration based on their specific preferences. At the beginning, it will show a status of **Initializing**.

 #### Tune the configuration for selected anomaly patterns
 
 If specific anomaly patterns are chosen, the next step is to fine tune the configuration for each. There's a global **sensitivity** that is applied for all series. For each anomaly pattern, you can tune the **adjustment**, which is based on the global **sensitivity**.
 
 You must tune each anomaly pattern that has been chosen individually.

 #### Tune the configuration for each series value group
 
 After the system generates statistics on all time series within the metric, several series value groups are created automatically. As described above, you can fine tune the **adjustment** for each series value group according to your specific business needs.
 
 There will be a default adjustment configured to get the best detection results, but it can be further tuned.

 #### Set up alert rules
 
 Even once the detection configuration on capturing valid anomalies is tuned, it's still important to input **alert
 rules** to make sure the final alert rules can meet eventual business needs. There are a number of rules that can be set, like **filter rules** or **snooze continuous alert rules**.

 After configuring all the settings described in the section above, the system will orchestrate them together and automatically detect anomalies based on your inputted preferences. The goal is to get the best configuration that works for each metric, which can be achieved much easier through use of the new **auto-tuning** capability.
