|CMU DFS Traces||
System-call traces from the CMU Coda project, 1991-93. More
This is a set of system-call traces collected for the Carnegie Mellon Online Coda Project. The traces cover 33 hosts running Mach. several different workloads are represented, including file server, workstation, and time-sharing systems. Less
System-call I/O traces of thirteen machines taken in 2000 and 2001. More
I/O traces taken at the system-call level in 2000 and 2001 as part of a security research project. The traces cover thirteen computers used for software development by CS researchers. The longest trace (machine02) runs from June 2000 to August 2001.
The traces are further described in a README file. The traces are in the SEER format; a tool to read the traces can be found here.Less
System-call traces (excluding read/write) of nine laptops, taken in 1996 and 1997. More
I/O traces taken at the system-call level, excluding reads and writes but including opens, closes and all other I/O calls, and including process-related calls such as fork and exec. The traces cover nine laptop computers used for software development by CS researchers, some with very heavy activity. The longest trace (norgay) extends from April 2, 1996, to January 28, 1997; the shortest (crockett) is October 11 to November 19, 1996. All traces contain gaps representing times when the machines were rebooted or the trace software failed. Activity by the superuser is generally omitted.
