Solusi Untuk Masalah Logger pada Zimbra 6.0.6 & SLES 10

Project pribadi saya saat ini adalah membuat Zimbra Appliance baik versi 32 bit maupun 64 bit berbasis SLES/openSUSE.

Zimbra 6.0.6 tersedia untuk SUSE Linux Enterprise 11 dan dapat digunakan pada openSUSE 11.x namun binary yang tersedia adalah versi 64 bit, sesuai rencana dari Zimbra mendorong penggunaan server-server 64 bit untuk menjalankan Zimbra. Meski demikian, karena sebagian besar pengguna komputer di Indonesia menggunakan mesin-mesin 32 bit, saya membuat Zimbra Appliance berbasis SLES 10 32 bit.

Proses instalasi berjalan lancar namun ada masalah pada Zimbra status dan logger problem. Service Zimbra semuanya running seperti terlihat pada screenshot berikut :

Namun jika membuka Zimbra Admin | Server Status atau Statistics, keluar pesan error sebagai berikut :

zmsoap -z GetLoggerStatsRequest stats/@name=zmmtastats | head -20 ERROR: service.FAILURE (system failure: Unable to read logger stats)

Masalah ini tidak terjadi pada Zimbra 6.0.6 yang berjalan pada SUSE Linux Enterprise 11. Setelah diskusi di forum openSUSE dan cari-cari dokumentasi di Zimbra forum, berikut adalah solusinya :

Pastikan zmlogger stop. Jalankan perintah berikut :
```
su - zimbra
zmloggerctl stop
ps ax | grep zmlogger
```
Kalau masih ada zmlogger yang berjalan, lihat PID number dan stop dengan hak akses root (exit dari posisi Zimbra user) :
kill -9 PIDNumber atau killall zmlogger
Buat ulang file database sqlite secara manual. Menggunakan hak akses root jalankan perintah berikut :
```
rm -rf /opt/zimbra/logger/db/*
/opt/zimbra/libexec/zmfixperms
```
Kemudian berikan perintah :
```
su - zimbra
/opt/zimbra/libexec/zmlogger&amp;amp;amp;amp;
```
Non aktifkan lagi zmlogger karena kita akan memodifikasi file syslog :
```
zmloggerctl stop
ps ax | grep zmlogger
```
Kalau masih ada service yang running, stop dengan perintah kill -9 PIDNumber atau killall zmlogger

Perbaiki file /etc/syslog-ng/syslog-ng.conf dengan perintah berikut (hak akses root) :

service syslog stop
mv /etc/syslog-ng/syslog-ng.conf /etc/syslog-ng/syslog-ng-backup.conf
vi /etc/syslog-ng/syslog-ng.conf

Kemudian paste kode berikut ini :

#
# Enable this, if you want to keep all messages in one file:

#destination allmessages { file("/var/log/allmessages"); };
#log { source(src); destination(allmessages); };

#filter f_local0 { facility(local0); }; # zimbra
#destination zmail { file("/var/log/zimbra.log" owner("zimbra") ); }; # zimbra
#log { source(src); filter(f_mail); destination(zmail); }; # zimbra

#destination zmauth { file("/var/log/zimbra.log" owner("zimbra") ); }; # zimbra
#log { source(src); filter(f_auth); destination(zmauth); }; # zimbra

destination zmauth { file("/var/log/zimbra.log" owner("zimbra") ); }; # zimbra
log { source(src); filter(f_auth); destination(zmauth); }; # zimbra

Kemudian simpan dengan menekan tombol ESC, :wq. Teruskan dengan mengaktifkan syslog kembali dengan perintah : service syslog start.

Jika anda terhubung ke internet, cara berikut lebih sederhana :

service syslog stop
mv /etc/syslog-ng/syslog-ng.conf /etc/syslog-ng/syslog-ng-backup.conf
cd /etc/syslog-ng/
wget -c http://vavai.com/wp-content/uploads/syslog-ng-sles10-ok.conf
mv syslog-ng-sles10-ok.conf syslog-ng.conf
service syslog start

Restart service Zimbra dnegan perintah :
```
zmcontrol stop
zmcontrol start
```

Error logger mestinya sudah tidak ada. Untuk service status, biasanya butuh waktu beberapa saat sehingga tanda silang status pada Zimbra Admin berubah. Jika statistics Zimbra Admin tidak menimbulkan error saat diklik, mestinya masalahnya sudah OK.
