The psyslrpt Command
You can use the
psyslprt
command to generate reports of log entries in the log
files generated on a set of nodes by syslogd. Options allow you to select the
files and records that will be reported.
Options and Parameters
-a Generates the report on all nodes in the system partition.
-e Reports on records before endtime (MMddhhmm).
-f facilities Uses the facilities list to parse the syslog.conf file.
-g config Specifies the use of an alternate syslog.conf file.
h Displays usage information.
-l logs (Lowercase L) Reports on the list of log files, if the syslog.conf
file is not parsed.
-n nodes Reports records matching the nodes.
-p priority Uses priority value to pass the syslog.conf file.
-s starttime Reports records created after starttime (MMddhhmm).
-w hosts Runs the command on the file or list of host names. If the
argument begins with a slash (/), it is interpreted as a file
containing a list of nodes to execute the command on. Otherwise
it can be a list of host names.
Note: If neither the
-a
nor
-w
options are used,
psyslprt
defaults to the local
node.
6.2.4 Trimming syslog Files
The size of the syslog log files is not configurable and will continue to grow until
you trim it manually.
The syslogd daemon is stopped during the trimming process and then restarted
with either the default configuration file (/etc/syslog.conf) or an alternate file.
To run the
psyslclr
command, you must be defined as a Kerberos principal in
the /etc/logmgt.acl file.
The fastpath to invoke the Trim Log Files SMIT menu is:
smit psyslclr
To trim all records older than 30 days from the log file /var/adm/msgs on the
local node, you can perform this command:
psyslclr -y 30 -l /var/adm/msgs
To trim all records from all log files found in the alternate syslog configuration
file /var/adm/syslog.conf, perform this command:
psyslclr -g /var/adm/syslog.conf -y 0
You can add the
psyslclr
command to the crontab to perform a scheduled
syslog trimming.
