According to Sun, the new Solaris 10 5/08 release will be available on April 14, 2008. This new release includes a lot of improvements and new features. Take a look into what’s new.
saidar is a top like tool. It provides a curses based interface for viewing system statistics such as network I/O, disk I/O, CPU, memory and more. The core of the functionality is provided by the libstatgrab library:
libstatgrab is a library that provides cross platform access to statistics about the system on which it's run. It's written in C and presents a selection of useful interfaces which can be used to access key system statistics. The current list of statistics includes CPU usage, memory utilisation, disk usage, process counts, network traffic, disk I/O, and more.
On a Debian system install the package as usual:
apt-get install saidar
and then run:
Debian allows you to record boot messages by means of the bootlogd daemon. According to man pages:
Bootlogd runs in the background and copies all strings sent to the /dev/console device to a logfile. If the logfile is not accessible, the messages will be kept in memory until it is.
This feature is not enabled by default. Edit /etc/default/bootlogd and modify it to enable recording of boot messages:
# Run bootlogd at startup ?
Now bootlogd will start sending boot messages to /var/log/boot.
