You can set the start date of the current baseline calculation, the number of scores
used to calculate the baseline, and the trend method. You also can deactivate or reactivate
KPI Signals monitoring for a KPI.

## Before you begin

Role required: admin, or must be a responsible user.

## Procedure

1. Open KPI Signals for a KPI.
2. Click the cogwheel to open the Configuration options.  

   <br />

3. Open the Signal Detection tab.  
   In this image, you see the Number of open incidents indicator with no breakdowns, and the same indicator with the Priority = 1-Critical breakdown and element. The KPI with the Priority = 1-Critical breakdown has been deactivated. Only KPIs that had been activated at some point appear in this list.   

4. Select the KPIs that you want to edit.
5. Fill in the following fields:  
   {#configure-signal-detection__table_brp_vv3_2nb__entry__2}

   | Field | Description |
   |-|-|
   | Active (check box) | Deselect to deactivate KPI Signals monitoring of the KPI. The KPI remains in the list afterwards. SelectActive later to reactivate monitoring on the KPI. If you reactivate monitoring on a KPI, it begins from the date you deactivated monitoring, not the date you reactivated it. |
   | Baseline start | The beginning date of the data points used to calculate the baseline. This date is based on the most recent resolved signal. If there never was a resolved signal, the date was set when monitoring on the KPI was first activated. |
   | Number of scores for baseline calculation | The number of scores, or data points, that the application uses to calculate the baseline. The default number of scores for calculating the baseline depends on the indicator frequency. Do not change this number unless you are confident you have good reasons. The minimum number is five. |
   | Trend method | The statistical method for calculating the baseline. Options are: * Linear trend, calculated by linear regression * No trend, just the average score {#configure-signal-detection__ul_wrc_yg4_2nb} |

6. Click Save.

## Linear trend versus no trend {#configure-signal-detection__example_rcx_t51_gnb}

In the following example, the initial linear trend kept resulting in signals despite
the average remaining stable. Following the signal in early September, signal
detection was changed to "no trend." Following this change, the average remained
stable and no further signals were detected.
