Cara menginstall qmailmrtg7 untuk memonitor traffic email, spam, virus, dan system

Kamu telah memiliki qmail server beserta spamassassin dan clamav? Ada baiknya kita memonitor statistic dari traffic email, spam, virus yang ada. Dengan adanya statistic ini, maka kita akan bisa mengetahui progress dari operasional server kita dari waktu ke waktu, dan bisa membantu kita di dalam mengambil keputusan apakah kita perlu menambah resource server (seperti ram, harddisk, dll), atau apakah sudah saatnya kita mengupgrade komponen2 qmail kita.

Qmailmrtg7 ini adalah paket yang bekerja sama dengan mrtg untuk menghasilkan report yang bisa kita lihat melalui web. Adapun paket2 yang kita perlukan adalah:
1. qmail, spamassassin, dan clamav. Pastikan bahwa sudah berjalan dengan baik. Tutorial ini hanya akan membahas installasi qmailmrtg7.
2. mrtg beserta library2nya. Sesuaikan dengan distro yang kamu pakai.
3. qmailmrtg7 dari http://www.inter7.com/index.php?page=qmailmrtg7
4. Script untuk memungkinkan qmailmrtg7 membaca format log spamd dan clamd.

Contohnya dapat dilihat di http://www.qmailrocks.org/extra/qmailmrtg_full.gif

Berikut ini adalah step-by-stepnya:
1. Extract qmailmrtg7 itu dan install:
make
make install

Ia akan menginstall file binarynya di /usr/local/bin

2. Copy file2 ini ke dalam direktori webnya, kalau perlu sediakan direktori sendiri, misalnya: /var/www/html/qmailmrtg7
index.html
qmail.mrtg.cfg

3. Setel file qmail.mrtg.cfg tersebut.
Lewati dahulu bagian yang mengenai spamd dan clamd. Sebab untuk kedua komponen ini perlu tambahan paket sedikit.

Berikut ini adalah isi dari file qmail.mrtg.cfg tersebut (yang telah saya modifikasi, juga beberapa bagian seperti ftp dan ssl saya matikan sebab saya tidak memakainya):

4. Setelah itu, sebagai root kita jalankan ini:
/usr/bin/mrtg /var/www/html/qmailmrtg7/qmail.mrtg.cfg

Kamu akan melihat error message. Jalankan command itu 3-4 kali. Kamu masih akan menemukan error message, terutama yang mengenai spamd dan clamd. Tidak apa2. Sekarang coba kamu buka webnya yang telah kamu buat sebelumnya, misalnya di http://domainkamu/qmailmrtg7/
Maka kamu akan mulai melihat grafik2 qmail dan system kamu. Grafik spamd dan clamd belum muncul. Happy? 🙂

5. Jangan terlalu happy dulu. Hehe.. Langkah selanjutnya adalah bagaimana menghasilkan grafik spamd dan clamd itu. Grafik ini menurut saya sangat membantu, sebab kita tahu belakangan ini serangan virus dan spam sangat mengganggu, jadi kita perlu tahu berapa besar serangan yg diterima server kita.

6. Nah langkah ke-6 ini yang rada tricky. Saya harus beberapa kali coba2 baru berhasil. Kita harus menginstall beberapa buat script yang akan membantu kita di dalam mem-parse log yang dihasilkan oleh spamassassin dan clamav.

Script2 tersebut adalah:
clammrtg.pl
glmrtg.pl
mrtgclamd
mrtgspam

Buatlah file2 tersebut dan isikan ini ke dalamnya masing2:

——- script selesai ——–

7. Ok, untuk mudahnya, copykan file2 script tersebut ke dalam /usr/local/bin
Jangan lupa untuk di chmod 755 agar bisa dieksekusi.

8. Setelah itu jalankan lagi command berikut beberapa kali sampai tidak muncul error:
/usr/bin/mrtg /var/www/html/baseqmailmrtg/qmail.mrtg.cfg

Command tersebut sebaiknya dimasukkan ke dalam cron job dengan interval 5 menit:
/etc/crontab
*/5 * * * * root /usr/bin/mrtg /var/www/html/qmailmrtg7/qmail.mrtg.cfg

Ok, selamat! Kamu telah memiliki statistik traffic email, spamd, dan clamd, serta system load yang dapat kamu akses melalui web.
Kalau ada kesulitan, silahkan tanya di forum yah 🙂
