1. A method comprising: determining a plurality of nodes in a call graph, the plurality of nodes representing resource consumption of functions of a software program executed in a software system; determining a simplification factor; eliminating, by a computing device, a first set of nodes in the plurality of nodes based on exclusive values for the plurality of nodes, inclusive values for the plurality of nodes, and the simplification factor, wherein an inclusive value for a node is based on a first amount of resources consumed by the node and one or more descendant nodes to the node, and wherein an exclusive value for the node is based on a second amount of resources consumed by the node; and outputting a simplified call graph including a second set of nodes in the plurality of nodes, the second set of nodes not including the eliminated first set of nodes.
