Linux and Unix server monitoring with "tail" command. Nice command for System Administrator.
Many times on linux's live servers we need to do find out, that what are system's messages for running processes on linux server, at that time linux monitoring tools will help us.
It might be redhat linux server, fedora core, ubuntu linux server, debain server etc.
We can easily monitor those log message with "tail" command. This command is very help-ful to linux and unix system administrators.
What ever type of log message will it be, e.g., log message, warning message, error message.
just open any bash shell terminal with root user login, and type "tail -f /var/log/message"
It will start displaying you the system log messages on screen with details, like time, machine name, process related info or warning or message.
We can easily dig or analysis into server's process which is generating message.
With this command it will continuously display the messages. To stop it we can use "Ctlr + c"
Hope this command will help system administrator to save time on live linux servers.
