N-1-3-040.50, "Problem Tracking Systems - Home-grown or
Off-the-Shelf", by Elise Gerich*, <epg@merit.edu>
Network Operations Centers (NOC) continue to work closely with each
other as the Internet has grown and has many more component networks.
With the growth and the added complexity of solving network problems,
it has become evident that network operations centers must document
actions taken to resolve problems.
The User Connectivity Working Group of the Internet Engineering Task
Force (IETF) is one example of a forum where discussions between
network operators have taken place on the topic of the format of
trouble ticket systems and the availability of public domain systems.
Discussions in working groups such as this one have led to documents
such as RFC 1297.
RFC 1297, "NOC Internal Integrated Trouble Ticket System Functional
Specification Wishlist", by Dale Johnson of Merit Network Inc.,
explores desirable features of trouble ticket systems for network
operations centers. After the publication of RFC 1297, several
organizations announced the availability of trouble ticket systems in
the public domain which implement some of the features that are
described in the RFC and which help to automate the maintenance and
distribution of information pertaining to network problems.
In April of 1992, the NEARnet technical committee announced the
availability of the code for the trouble ticket system that was
developed by the NEARnet technical staff. This trouble ticket system
is based on the Informix Relational Database and allows problems and
the related notes to be maintained in a coordinated fashion. It is
also possible to distribute trouble ticket information via electronic
mail to other network operations centers or interested parties.
The current release package was prepared by Leo Dopson and John Curran
and contains several descriptive documents and an easy-to-use
installation script for customizing the system. The system is
available via anonymous FTP on nic.near.net, in the file:
pub/nearnet-ticket-system-v1.2.tar.
This system is currently used by NEARnet and has helped NEARnet build
the reputation for thorough problem resolution. Bug reports,
discussions, fixes, improvements, and questions about this system
should be addressed to: tt@nic.near.net.
A second publically available Help Desk Management System (HDMS) is
available from Delmarva Power & Light Company. This system requires
the Unify relational database and has a character-based interface. It
is inherently multi-user, and supports problem escalation, email
interface, and remote ticket printers. For further information about
HDMS, address mail to: hdms-request@delmarva.com.
A third system has been announced by JVNCnet in May 1992. NETLOG v2.0
is available via anonymous FTP on ftp.jvnc.net, in the file:
pub/netlog-tt.tar.Z.
Unlike the previous two systems, this software is not based on an
off-the-shelf database. It runs on Unix systems and has been used by
JVNCnet since 1990. This software is part of the NOCOL (Network
Operation Center On Line) package developed at JVNCnet.
This software was developed prior to the publication of RFC 1297. Some
of the features like alarms which are mentioned in the RFC are not
part of NETLOG, but may be implemented sometime in the future. The
functions that are supported include:
Create Entry
Edit Log
Read Log
List Open Tickets
Search Logs
Process Tickets
All bug reports, comments, and suggestions should be sent to:
netlog-bugs@jvnc.net. To be advised of updates to this software, send
mail to: netlog-users@jvnc.net.
A fourth system, which will be based on RFC 1297, is being developed
by Tom Sandoski at Concert Network. This system will be based on the
postgres database system which is publically available from
postgres.berkeley.edu. When this is publically available, there will
be an announcement to the User Connectivity Problems Working Group and
Network Joint Management Working Group of the IETF.
There may be more publically available systems. These are just four
that have been shared on IETF mailing lists.
The network operations centers have cooperated in working together to
resolve network problems and continue the cooperation by collaborating
to develop criteria for basic trouble ticket systems which improve
operator efficiency and accuracy. This collaboration has translated
into publically available problem tracking systems which ultimately
lead to better service to network users.
