How to Collect Information for a Support Tools Installation
Installation Step 1
Prior to installing Support Tools, collect the following information that you will need
to provide during the install:
For the Support Tools Server:
A. Determine the name of the Support Tools privileged user group. Determine which
users will be members of this group.
B. Determine the username, domain, and password of the distinguished user for the
Tomcat Web server.
C. Determine the IP address or fully-qualified DNS of your network time server (see
below for more).
For the Support Tools Node:
A. Take an inventory of the ICM nodes on which you want to install Support Tools.
B. Determine the IP address or fully-qualified DNS of your network time server.
C. Determine whether a firewall stands between the Support Tools Server and any
ICM nodes it will manage.

About the Network Time Server

To use Support Tools merged log capabilities, each Support Tools Server and node
must be able to communicate with the same Simple Network Time Protocol (SNTP or
NTP) server. This is required even for networks that have fully synchronized
Windows 2000 systems as the allowable machine drift is greater than the tolerance
of the log event times.
Note that Support Tools does not make time adjustment to host machines. Instead,
the time offsets are tracked in a database to use for log merging only. Your SNTP or
NTP server must support unauthenticated requests. Refer to RFC-2030 for more
details on SNTP. Most Cisco IP Routers support the SNTP / NTP protocol. Consult with
your IT department on available SNTP / NTP servers in your network.
If any system in a merged log collection cannot communicate with the SNTP server,
the merge will fail, and the outputted log will contain the alert: "Missing SNTP data
for all of the following files logs prevented merging logs:..."
