recommended partition size to hold auditd logs & BSM logs

sunhux used Ask the Experts™
If we have a need to retain (can be in zipped/gz format) bsm
(Solaris Basic Security Module), what's the sizing of the partitions

I know it depends on the amount of activity but suppose I
currently have 2GB left, how much more to extend?

BSM is merged with auditd logs

Best to extract the data from the log on an ongoing basis and record it in a searchable db

Since you have to retain the data for a certain duration it is hard to predict how much space you would need.
You could compress.


Refer to attached for my current utilization:

can auditlog.1/../.9   be compressed or these 'non-readable'
files are already highly-compressed?  
see  /bsm_aud/auditlogs  folder

Those big files under ./bsm_aud   ie the
2019mmddhhmmss.SS89  files are quite recent files
& can they be gzipped without any impact??

how much to increase depends upon the size increase per day.  i.e. if it increases by 1MB /day  and you increase by 1GB then you have 1000 days left

Better to place this on one partition for "/" as trying to reserve space on a custom partition will either cause you to be short of space, losing log data or create a massive amount of space which remans empty/unused.


Ok, from Tivoli/other monitoring tools, guide is to have
30-35% of free disk space.

The implementation of a syslog server is fairly straight forward since it is installed by default in all distro's.

You should consider an implementation that extracts the data of interest.
Rsyslog is an improvement over the syslog that is commonly installed on Solaris 10
Do you have, use a monitoring tools some include a syslogger option that can receive notification.
