[petsc-users] PC FieldSplit - How to Count the Iterations

Dear PETSc Developers and Users,

I’m working with PCFieldSplit preconditioner (Schur complement based approach). 
To count the number of iterations I’m taking the info from subksp_0 and subksp_1.
I understand that the number of its for subksp_1 are related to the call for the solution of the Schur complement.
What is the number of its that I get from subksp_0? Is it the total number of calls or is it just related to the last solution for A00?
In the second case, is there a strategy to have the total number?

My best regards and thank you,
