Historical Section : System Call Traces
The Historical Section includes all traces that are older than 10 years. System Call I/O Traces typically reflect operating system calls to the file system.

| LASR Traces |
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. | 1999-2001 | over 1 year | 566 Million | 3.17 GB |

| LASR Traces (ASCII) |
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 have been converted to ASCII using the binary tool to read the Seer format. | 1999-2001 | over 1 year | 566 Million | 5.49 GB |

| Seer Traces (ASCII) |
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.
Additional information about these traces can be found here. |
These traces are already in readable (ASCII) format. | 1996-1997 | about 1 year | 72 Million | 792 MB |
