Existing program code, which is executable on one or more computers forming part of a distributed computer system, is analyzed. The analysis identifies log output instructions present in the program code. Log output instructions are those statements or other code that generate log messages related to service requests processed by the program code. A log model is generated using the analysis. The log model is representative of causal relationships among service requests defined by the program code. The log model can then be applied to logs containing log messages generated by execution of the program code, during its normal operation, to group log messages for improved analysis, including visualization, of the performance and behaviour of the distributed computer system.
