The /var/adm/messages in Solaris seem to log more system messages/errors compared to /var/log/messages in Linux.
I checked the log level in Linux and they seem OK.
Is there any other log file that contains the messages or is it just that Linux doesn't log great many things? (2 Replies)

sysdiagnose
sysdiagnose(1) BSD General Commands Manual sysdiagnose(1)
NAME
sysdiagnose -- gathers system-wide diagnostic information helpful in investigating system performance issues
SYNOPSIS
sysdiagnose -h
sysdiagnose [-f results_directory] [-A archive_name] [-V volume_path] [-n] [-k] [-F] [-S] [-u] [-Q] [-b] [-p] [-P] [-d] [-D] [-r] [-R]
[process_name | pid]
DESCRIPTION
The sysdiagnose tool gathers system diagnostic information helpful in investigating system performance issues. A great deal of information
is harvested, spanning system state and configuration. The data is stored /var/tmp directory. sysdiagnose needs to be run as root. To cancel
an in-flight sysdiagnose triggered via command line interface, press Ctrl-. sysdiagnose is automatically triggered when the following key
chord is pressed: Control-Option-Command-Shift-Period.
What sysdiagnose collects:
o A spindump of the system
o Several seconds of fs_usage ouput
o Several seconds of top output
o Data about kernel zones
o Status of loaded kernel extensions
o Resident memory usage of user processes
o Recent system logs
o A System Profiler report
o Recent crash reports
o Disk usage information
o I/O Kit registry information
o Network status
o If a specific process is supplied as an argument: list of malloc-allocated buffers in the process's heap is collected
o If a specific process is supplied as an argument: data about unreferenced malloc buffers in the process's memory is collected
o If a specific process is supplied as an argument: data about the virtual memory regions allocated in the process
OPTIONS
-h Display help.
-v Enable verbose mode to display the container information as it executes.
-f results_directory
Specify the directory where the results will be stored. The default results directory is /var/tmp.
-A archive_name
Specify the name of the archive created in the results directory.
-V volume_path
Specify the root volume for sysdiagnose to run on.
-n Do not tar the resulting sysdiagnose directory.
-k Do not remove the temporary directory.
-F Get feedback data.
-S Disable streaming to tarball.
-u Disable UI feedback.
-Q Skip footprint.
-b Do NOT show the resulting archive in a Finder window upon completion.
-p Collect only time-sensitive data. Disregards previous -d or -r flags.
-P Do not collect time-sensitive data.
-d Collect only log data. Disregards previous -p or -r flags.
-D Do not collect log data.
-r Collect only log archive. Disregards previous -p or -d flags.
-R Do not collect log archive.
process_name | pid
If a single process appears to be slowing down the system, passing in the process name or ID as the argument gathers additional
process-specific diagnostic data. Specify only ONE process at a time -- specifying multiple processes is not supported.
EXIT STATUS
sysdiagnose exits with status 0 if there were no internal errors encountered during the diagnostic, or >0 when an error unrelated to external
state occurs or unusable input is provided by the user.
