Solaris logs different events in different directories most of them is in /var. Please specify for which log u r looking for. I am enclosing some of them.
/var/adm This directory is usually also available as a symbolic link named /usr/adm.
/var/log This log directory is sometimes used to store miscellaneous log files, including log files ceated by syslog for messages that are not written to /usr/adm/messages or to the system console.
/var/cron This directory contains the files that you would find associated with the system's cron(1M) and at(1) functions.
