sos, machine information collection tool

A few weeks back, I have encountered a problem on one of my redhat server. Since the server is licensed, I send an email to redhat customer support through redhat network in search for the solution. The first thing that redhat reply to me was to run a command named 'sosreport'. What is sosreport?

According to the man page:
Sosreport (formerly known as sysreport) generates a compressed tarball of debugging information for the system it is run on that can be sent to technical support reps that will give them a more complete view of the overall system status.

Sosreport belongs to the sos package:

# whereis sosreport
sosreport: /usr/sbin/sosreport
# rpm -qf /usr/sbin/sosreport
# rpm -qi sos
