A word about error handling

When working with the error handling inside ConnectPlaza, you have to be aware how this mechanism works. Otherwise you can get quite unexpected behaviour and in some cases disk that will fill up quite quick, with all problems accordingly.

You can have two places to set the error handling. The first is on the interface, the second is on the flow.

Interface Look

Flow look

In both screens it is about the next two fields:

Select the default error flow, storeChannel, of type the error flow of your choice. Both fields are internally the same value.

What you need to know

What you need to know is that the error handling assigned to the interface is active for all the flows active in this interface. This is no problem for most cases, but if you have defined the error handling to a flow present in this interface you can have issues if the error handling flow is producing errors. You will get a loop.  The error handling flow is assigned the error handling flow for errors, but there are errors......  etc.

Imagine that your error handling flow has an Analyze Wiretap, all the data is written to the Analyze database, and because of the looping effect, this is a serious issue.

In above case it is better to set the error handling at flow level.
