Monitoring
Overview
HP NonStop SSL writes log and audit messages to a terminal, to a file, or to EMS. This is controlled by the parameters
LOGCONSOLE, LOGFILE and LOGEMS for log messages and AUDITCONSOLE, AUDITFILE and AUDITEMS for
audit messages. Messages can be written to any combination of those three “targets” (i.e. a single one, two of them, all of
them, none of them). By default, log and audit messages are neither written to EMS nor to a log file.
Most parameters mentioned in this chapter can be configured both during startup as well as once HP NonStop SSL is
running already. In the latter case, the parameters can be changed by using SSLCOM (see chapter "
SSLCOM Command
Interface " for details).
What is a log message?
A log message is issued by HP NonStop SSL for informational purposes, as a warning, or to indicate a fatal condition,
which cannot be corrected automatically.
What is an audit message?
A audit message is issued by HP NonStop SSL for security-relevant events, such as network event (connect, disconnect),
or FTP operations
Why are there three different target devices?
There are three different devices which to messages can be logged, i.e. a terminal, a file, or EMS. Operators may choose
their favorite location for being alerted.
For productive installation, it is recommended to either have HP NonStop SSL log events to a file (LOGFILE,
LOGFORMATFILE, LOGLEVELFILE) or to EMS (LOGEMS, LOGFORMATEMS, LOGLEVELEMS).
Log levels of these three devices can be different, i.e. can be written independently from each other.
What is a log/audit level?
A log or audit level is a number assigned to a every message in order to indicate its importance or grade of detail
information. In general, a higher log or audit level for a given message indicates less importance or detail. While log or
audit levels of individual messages cannot be changed, it can be controlled which levels will be displayed at all through
the LOGLEVELxxx or AUDITLEVELxxx parameters.
