Patent ID: 7810075

Claim:
A computer-implemented method comprising: obtaining trace information from local memories associated with virtual machines, the trace information including virtual machine trace information relating to the virtual machines and worker node trace information relating to worker nodes corresponding to the virtual machines; performing content-based filtering of the trace information obtained from the local memories such that the virtual machine trace information is separated from the worker node trace information, wherein each local memory associated with a virtual machine stores a portion of the trace information including a portion of the virtual machine trace information relating to the virtual machine and further stores a portion of the worker node trace information relating to a worker node corresponding to the virtual machine, the worker nodes and the virtual machines relating to software applications running on an application server of a computer system; merging the filtered worker node trace information obtained from the local memories into a single worker node trace file; and merging the filtered virtual machine trace information obtained from the local memories into a single virtual machine trace file.
