Mailbox Gmail penuh!

Published on August 27, 2006 in internet and teknologia. 1 Comment

Setelah selama ini menggunakan Gmail tanpa masalah, dan menganggap webmail paling enak dipakai dari yang laen-laen… Ternyata akhirnya kutemukan kelemahan Gmail! \:D/

Waktu menunjukkan sekitar jam 07:00 pagi. Waktunya bersiap-siap untuk pulang. Kusempatkan sedikit waktuku buat baca-baca conversation milis di gmail. Ingin mereply salah satu email… Dan saat klik tombol send, muncul pesan penolakan dari gmail yang nggak mau mengirimkan emailku. :(
Ternyata ada text berwarna merah bertuliskan: You are currently using 2758 MB (74%) of your 2758 MB.

Yap! inboxku penuh. Nggak ada cara lain, bisa ditebak satu-satunya cara untuk membebaskan sebagian kapasitas gmailku. Kutulis kata lowongan dan klik Search Mail :D . Ada ribuan email berhasil ketangkep. Gmail sempat mabok beberapa kali saat semua email itu dihapus sekaligus :D

At last… ada ruang sisa lagi di gmail: You are currently using 2030 MB (74%) of your 2758 MB. :)

Sysstat

Published on August 27, 2006 in linux and teknologia. 0 Comments Tags: , , .

Karena nggak berhasil install Phpsysinfo :( Jadi selarang kita coba Sysstat dech :D

Tapi sebelum mulai, apa sih Systat itu?

Jawab: Semacam paket utiliti yang mungkin membantu System Admin mengumpulkan informasi performa dan mencatatnya (kira-kira begitu).

Installnya juga cukup mudah:

[root@fidzNux hafidz]# yum install sysstat
Setting up Install Process
Setting up repositories ……

Installed: sysstat.i386 0:5.0.5-7.rhel4
Complete!
Alhamdulillah…. Selesai deh

[root@fidzNux ~]# sar
Linux 2.6.9-34.EL (fidzNux) 08/27/2006

Selanjutnya kita buat sar running setiap hari

[root@fidzNux ~]# more /etc/cron.d

*** /etc/cron.d: directory ***

[root@fidzNux ~]# more /etc/cron.d/sysstat
# run system activity accounting tool every 10 minutes
*/10 * * * * root /usr/lib/sa/sa1 1 1
# generate a daily summary of process accounting at 23:53
53 23 * * * root /usr/lib/sa/sa2 -A
Ada dua script yang dihasilkan: sa1 mempunyai output dalam format binary Sysstat, dan sa2 dalam bentuk text biasa yang bisa kita baca. Report dari dua script ini tersimpan dalam direktori /var/log/sa

[root@fidzNux ~]# ls /var/log/sa
sa27 sar27

—-> angka 27 merupakan hari sekarang

[root@fidzNux ~]# sar
Linux 2.6.9-34.EL (fidzNux) 08/27/2006

05:00:01 AM CPU %user %nice %system %iowait %idle
05:10:01 AM all 0.18 0.00 0.08 0.23 99.51
Average: all 0.18 0.00 0.08 0.23 99.51

Kita bisa melihat penggunaan CPU, kerja internal CPU, dan delay waktu yang dibutuhkan dalam proses input/output.

Kita juga bisa melihat status penggunaan swap.

[root@fidzNux ~]# sar -W
Linux 2.6.9-34.EL (fidzNux) 08/27/2006

Untuk melihat system load gunakan command berikut:[root@fidzNux ~]# sar -q
