MOTDstat Documentation
|
||||
================================================================================
|
||||
|
||||
MOTDstat will dynamicaly generate the /etc/motd file with current
|
||||
information about system resources and usage. Using crontab the script will
|
||||
periodically display status of system resources and services. The original
|
||||
message of the day is now stored in /etc/motd.orig file.
|
||||
By configuring e-mail address you'll receive the notifications about
|
||||
following issues:
|
||||
|
||||
o high CPU load (configurable warning/critical limits)
|
||||
o exceeding disk space (configurable warning/critical limits on
|
||||
partitions)
|
||||
o intensive usage of SWAP space (configurable warning/critical limits)
|
||||
o specific process is not runnig
|
||||
o specific local network service is not running
|
||||
o NTP is not synchronized with network peer(s) (ntpq is required)
|
||||
o too many e-mails in mail queue (mailq is required)
|
||||
o system reboot
|
||||
|
||||
|
||||
The system status report is organized into three columns:
|
||||
|
||||
o 1st column contains information about partition(s) free space and
|
||||
usage in percentage.
|
||||
o 2nd column will display information about used memory and SWAP space
|
||||
o 3rd column will monitor running processes and local network services
|
||||
|
||||
You are able to modify the disk space warning and critical limits per
|
||||
mounted filesystem. First time you run the MOTDstat, the fstab_limits file will
|
||||
be generated with default warning and critical limit. You can setup the limits
|
||||
by your needs. If some partition is not mounted, the notification e-mail will
|
||||
be send.
|
||||
|
||||
|
||||
INSTALLATION:
|
||||
============
|
||||
type : ./Install.sh
|
||||
|
||||
Customisation:
|
||||
=============
|
||||
When you want MOTD to be displayed while logging via SSH client you will
|
||||
have to change setting on the SSH daemon as following: /etc/ssh/sshd_config
|
||||
|
||||
~snip~
|
||||
PrintMotd yes
|
||||
~snip~
|
||||
|
||||
To apply the changes, restart the SSH server daemon.
|
||||
|
||||

||||
