commandlog

commandlog(4)						     Sun Cluster File Formats						     commandlog(4)

NAME

       commandlog - command log file

SYNOPSIS

       /var/cluster/logs/commandlog

DESCRIPTION

       The  commandlog	ASCII  text file contains records of selected Sun Cluster commands that are executed in a cluster. The logging of commands
       starts automatically when you set up the cluster and ends when you shut down the cluster.

       Commands that are not logged in this file include those that display the configuration and current state of the cluster. Commands that  are
       logged in this file include those that configure and change the current state of the cluster, as follows:

	   o	  claccess

	   o	  cldevice

	   o	  cldevicegroup

	   o	  clinterconnect

	   o	  clnasdevice

	   o	  clnode

	   o	  clquorum

	   o	  clreslogicalhostname

	   o	  clresource

	   o	  clresourcegroup

	   o	  clresourcetype

	   o	  clressharedaddress

	   o	  clsnmphost

	   o	  clsnmpmib

	   o	  clsnmpuser

	   o	  cltelemetryattribute

	   o	  cluster

	   o	  scconf

	   o	  scdidadm

	   o	  scdpm

	   o	  scgdevs

	   o	  scrgadm

	   o	  scshutdown

	   o	  scswitch

       Each record in the commandlog file contains the following information:

	   o	  Date and timestamp

	   o	  Host name from the which the command was executed

	   o	  Process ID of the command

	   o	  ID of the user who executed the command

	   o	  Command that the user executed, including all options and operands

	   Note -

	     Command options are quoted in the commandlog file to enable you to copy, paste, and execute them in the shell.

	   o	  Exit status or signal of the executed command

       By  default, the commandlog file is regularly archived at the end of every week. Sun Cluster maintains up to eight previously archived com-
       mandlog files on each cluster node at any given time.
