iLO or an IPMI BMC. System Events are hardware-related alerts such as memory
errors, power supply faults, and so on.
System Event Log

14.5 Understanding Nagios alert messages
HP Insight Control for Linux provides several value-added plug-ins that can generate alert
messages based on patterns provided by various data sources, such as syslog and the Hardware
System Event logs.
All these plug-ins use a common syntax to describe patterns and status to report on matches.
The rules that trigger alarms are configured in the following files:
• /opt/hptc/nagios/etc/selRules
Contains patterns for alerting on System Event Log messages.
You can modify the selRules file as follows:
— Add a rule to this file for a new alert.
— Modify the corresponding rule to change an existing alert.
— Comment out a rule to remove the corresponding alert.
• /opt/hptc/nagios/etc/syslogAlertRules
Contains patterns for alerting on consolidated log entries.
• /opt/hptc/nagios/libexec/sensorData.dat
Contains patterns for alerting based on sensor results.
Nagios uses email to send formatted alerts. The following is the default format of a Nagios alert:
Type: PROBLEM
