Most of the relevant logs are managed with the syslog commands, where you set rotation and other parameters to suit your own monitoring and management schedule.
The NTP logs are not included in the periodic rotations in Luna SA. Our experience is that most customers want to accumulate NTP logs in one continuous file over a long period of time. Events are sufficiently infrequent that the NTP log file won’t grow very fast, and so would never fill up the whole log directory.
Similarly, HSM logs are excluded from periodic rotation. A security auditor would likely want to see the complete HSM log (hsm.log).
Customers can delete NTP logs and other log files, except hsm.log, using this command:
lunash:>syslog cleanup
For NTP tracking and administration, only the ntp.log file is important. Ensure that you have retrieved a copy of that file before you run 'syslog cleanup'.
Hardware monitoring and logging
1. SMART technology monitors the hard disk.
2. IPMI technology monitors CPU fan speed and temperature, as well as PSU (power supply unit) voltage, fan speed and temperature.
The system logs temperature changes of 2 degrees in either direction.
