Abstract

VM systems programmers must deal with a large number of service machines. Most of these service machines produce periodic console logs and other monitoring logs that are intended to assist the systems programmer in maintaining the service machines and diagnosing problems. Unfortunately, the amount of data presented in such logs is quite large. Identifying and resolving problems is often complicated by the volume of data or, at the other extreme, the lack of data when the logs are not available. A facility was needed to assist in analysis of the raw console file data and a repository for retention of the console files for some user selected time.

Console Log Maintenance Facility

       VM systems programmers must deal with a large number of
service machines.  Most of these service machines produce periodic
console logs and other monitoring logs that are intended to assist
the systems programmer in maintaining the service machines and
diagnosing problems.  Unfortunately, the amount of data presented in
such logs is quite large. Identifying and resolving problems is often
complicated by the volume of data or, at the other extreme, the lack
of data when the logs are not available.  A facility was needed to
assist in analysis of the raw console file data and a repository for
retention of the console files for some user selected time.

      CONMAN (CONsole  MANager) is a VM service machine which
analyzes console logs, alerts the appropriate programmer if unusual
circumstances occur, and holds console files (in terse format) for
some predefined period.  CONMAN works based upon two configuration
files.  The first file identifies, based upon the userid and node of
the originating service machine, the appropriate second configuration
file to be used in conjunction with a given console file.  The second
configuration file, also called the analysis profile, identifies a
userid and node to be notified of the results of the analysis and the
parameters to be used.  There can be many analysis profiles in use on
a single CONMAN service machine.

      A number of analysis options may be set by the owning syste...
