mail-logs.pl provides a simple way to extract your logs from the previous
day and deliver them to any email address.
The mail-logs.pl was created to help ensure that the logs were checked, and
archived every day. Email delivery allows multiple people the ability to read
thru the log with out requiring access to the files. Also the email messages
provide a 'backup' of the log files.
mail-logs.pl does not accept any command line options. It parses log files
defined in the script and delivers an email for each log file to the address
specified.
Requirements for the script are described in the comments found at the
beginning of the script. Basically you will need to make sure the following
commands are available: dnsdomainname, hostname, date, and ls. Also the perl
module
Net::SMTP needs to be properly setup for this script to
work.
Bellow is a description of the various variables that need to be defined or
setup for the script to function properly.
@logFiles
logFiles is a list standard syslog log files to be parsed. When defining
this do not worry about logs rotated using logrotate - this script should
parse those logs also... for example if "/var/log/syslog" is specified
/var/log/syslog* will be parsed and included in the same message, as long
as they are either plain text or gziped plain text.
Here is an example email using /var/log/mail.warn in @logFiles:
---<tmp.msg>---
To: thompson@cns.uni.edu
From: mail-logs@server.cns.uni.edu
Subject: server.cns.uni.edu /var/log/mail.warn Jun 29
/var/log/mail.warn
=====================================
Jun 29 12:09:25 server imapd[11375]: pam_ldap: [...]
Jun 29 12:09:25 server imapd[11376]: pam_ldap: [...]
Jun 29 21:26:35 server imapd[16266]: pam_ldap: [...]
/var/log/mail.warn.0
=====================================
Jun 29 03:28:56 server imapd[5837]: pam_ldap: [...]
/var/log/mail.warn.1.gz
=====================================
/var/log/mail.warn.2.gz
=====================================
/var/log/mail.warn.3.gz
=====================================
---<tmp.msg>---
When defining @logFiles each file name (or file-base name) should be double
quoted string. Following basic perl list definition rules.
The default value for @logFiles is:
("/var/log/messages", "/var/log/syslog",
"/var/log/kern.log", "/var/log/auth.log",
"/var/log/daemon.log", "/var/log/user.log",
"/var/log/vsftpd.log", "/var/log/mail.err",
"/var/log/mail.info", "/var/log/mail.log",
"/var/log/mail.warn", "/var/log/uucp.log");
$server
The $server is used to define which SMTP server to connect to
when sending the email. Give the full DNS name. Use host or dig
to find your DNS name.
$mailTo
$mailTo is the email address that will receive the messages for each log
file. Currently mail-logs.pl does not support more than one email
address to be defined here. Define an email list to contain the various
people that should receive a copy of the mail messages.
$mailFrom
Use this to change who is listed on the "From:" line in your email
headers. By default the script uses "mail-logs\@$hostname";
$subject
The $subject found in the main part of the application is currently
ignored. The subject is currently defined in the mailLogs sub-program.
$message = "";
The $message found in the main part of the application is currently
ignored. $message is re-written for each logFile in the mailLogs
sub-program.
There are a few other system services that do not use the syslog standard log
file format these services each have their own sub-program which may require
configuration on its own.
sub-program Service Description
