Printing during chain execution

When executing a chain, you will see something like the following in the logs:

[ea1af4810cc849d58948d091d858b29a]:[O]start component[ACmp] execution
[ea1af4810cc849d58948d091d858b29a]:[O]start component[BCmp] execution
[ea1af4810cc849d58948d091d858b29a]:[X]start component[CCmp] execution
[ea1af4810cc849d58948d091d858b29a]:[O]start component[DCmp] execution

The first sequence number represents the request ID of the request. No matter how many components a request has gone through, their request IDs are the same. You can quickly locate and troubleshoot in the log based on this ID.

It will be followed by an [O] or [X], [O] represents the main logic that executes the component, and [X] represents the main logic that did not enter the component because isAccess() returned false.

If you don't want to print this kind of intermediate execution information, LiteFlow provides configuration items, you need to do the following settings:

liteflow.print-execution-log=false

Printing step information

After executing a chain, the framework will automatically print the sequence of execution steps of this chain, as shown below:

a<100>==>c<10>==>m<0>==>q<200>==>p<300>==>p1<0>==>g<305>

The expression here is: component ID <time in milliseconds>

If you want to add an alias description when printing the process chain, you need to set the name attribute when defining the component. For details, please refer to Component Aliases.

After adding the alias, the printing of the execution step information will become as follows:

a[cmpA]<100>==>b[cmpB]<0>==>m[cmpM]<256>

The expression here is: component ID[component alias]<time in milliseconds>
