Use this page to add processors to the *Instances* canvas individually and connect them manually. To create a complete flow with connections added automatically, see [Create an Analytics Flow](docId\:ewmyJSlRbisGimPDgq82A).

# Add a Processor

**To add a processor:**

1. Navigate to **Analytics** > **Instances**.
2. In the *Instances* pane, use the *Analytics Groups* drop-down list to select the group you want to add the processor to.

4. In the *Create a Processor* dialog, use the drop-down list to select a processor. Processors are categorized as *Inputs*, *Functions*, and *Outputs*.
5. Configure the parameters for the processor.
6. Click **Save**.

# Add a Processor Connection

To connect two processors, click the orange circle on a processor and drag to the green circle on the other processor. Select the connection type:

- **Events** (individual data source): The receiving processor reacts to each data value immediately.
- **Values** (combined data sources): The function processor waits for values from all connected input sources before processing.

If a red error icon appears on a connected processor, hover over the connection to view the error message.

**Note**: Some function processors require multiple inputs. Each additional input requires its own input processor and connection.
