SYSLOG GUIDELINES
5.1
Managing Disk Space
Syslog stores logging events. Depending on the compression level, from 16MB to 300MB of events may
be stored.
Periodically( every 1 hour), the system checks the space available and performs the following steps:
1.
After every reboot or after every 1 hour when and if 65% of the available space has been utilized,
the 3 largest files will be truncated to 5K lines. Syslog would not report anything.
2.
If the 85% of the available space has been used, the 3 largest log files are truncated to up to 2K
lines. Syslog would report (this will be available in a future implementation):
3.
If above 95% of the available space has been used, the 3 largest logs will be cleared. Syslog would
report as follows (this reporting capability will be available in a future implementation):
