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.
