Open Integration Manager Preprocessing Functions

Find information about preprocessing functions performed on complex OIM integrations.

Before being ingested into BigPanda, the Open Integration Manager performs preprocessing functions on some complex integrations. Preprocessing functions are essential components of OIM that transform, delete, create, or update incoming data before it reaches OIM. This allows the data to be mapped appropriately to tags in BigPanda. You can view these functions in the Integration Manager tab within OIM.

Preprocessing functions are visible within the Integration Manager tab in OIM integrations. To view preprocessing functions used on the integration, click the Settings cog icon.

If there are no preprocessing functions performed on the integration, the Settings cog icon will be greyed out and display the number zero next to it.

The Preprocessing Functions window shows all global and custom functions applied for the integration. Click the arrow on the preprocessing function box to expand details about the function. The following information is available:
