Sebagai seorang admin yang handal tentu harus memonitor log server secara rutin, hal ini tentu sangat merepotkan apabila tiap pagi mengharuskan membuka log file satu persatu. Nah disini saya coba membahas bagaimana bila log2 tersebut dibundle jadi satu kemudian dikirim lewat email, tentu sangat memudahkan bukan?? (malas mode : on ^_^).
Saya tertuju pada smtp email client yaitu sendEmail (bukan sendmail , tapi sendEmail !!), jadi disini tidak perlu menginstall Mail server seperti postfix,zimbra dll, tapi cukup menggunakan smtp client yakni sendEmail.

Ok kita langsung bahas langkah2 nya !!
Download sendEmail :

Disini sendEmail sudah terinstall, perintah untuk kirim email :
Note : Email Yahoo maupun Gmail sudah mendukung protocol pop3 dan smtp asalkan opsi untuk protocol tersebut diaktifkan, maka mengirim email lewat smtp seperti diatas akan sukses.
Contoh test kirim email :
Kemudian kita download paket logwatch

$ sendEmail -v -f username@mail.com -s smtp.googlemail.com:587 -xu username -xp yourpassword -t emailtujuan -o tls=yes -u subject email -m isi email -a attachment jika ada
Note : Email Yahoo maupun Gmail sudah mendukung protocol pop3 dan smtp asalkan opsi untuk protocol tersebut diaktifkan, maka mengirim email lewat smtp seperti diatas akan sukses.
Contoh test kirim email :
$ sendEmail -v -f s****y@gmail.com -s smtp.googlemail.com:587 -u testingemail -xu s****y -xp ***** -t sonny@s*****k.com -m test email -o tls=yes
Penjelasan :
-f alamat pengirim
-t alamat tujuan
-u message subject
-m message body
-s smtp mail relay, default is localhost:25
-a file attachment(s)
-cc cc email address(es)
-bcc bcc email address(es)
-xu username for SMTP authentication
-xp password for SMTP authentication
-o optional
Jika masih kurang jelas silakan baca file README nya !!Kemudian kita download paket logwatch
$ sudo apt-get install logwatch
Backup dan ubah konfigurasi logwatch
$ sudo cp -v /usr/share/logwatch/default.conf/logwatch.conf /usr/share/logwatch/default.conf/logwatch.conf_backup
$ sudo nano /usr/share/logwatch/default.conf/logwatch.conf
tambahkan tanda # didepan untuk
----------------------------------------------------------------
#MailTo = root
#MailFrom = Logwatch
#mailer = "/usr/sbin/sendmail -t"
Detail = Med ### kecuali yang ini ubah dari Low ke Med
----------------------------------------------------------------
Save and exit
Buat Script untuk Log dan kirim email
$ nano logtoemail.sh
----------------------------------------------------------------
#!/bin/bash
usr/sbin/logwatch --output file --filename ~/logcomplete
/bin/cat /var/log/boot.log >> ~/logcomplete
/bin/cat /var/log/backup.log >> ~/logcomplete ##> tambahkan lagi jika msh ada log yg ingin disertakan
/usr/local/bin/sendEmail -f t***@gmail.com -s smtp.googlemail.com:587 -xu t*** -xp ***** -t sonny@s*****k.com -o tls=yes -u report -m report -a ~/logcomplete
----------------------------------------------------------------
Tambahkan Permission :
$ sudo chmod +x logtoemail.sh
Tambahkan di crontab :
$ sudo crontab -e
----------------------------------------------------------------
0 8 * * * /home/sonny/logtoemail.sh
----------------------------------------------------------------
Sekarang, email log akan dikirim setiap hari pada jam 8 pagi.
