Selamat pagi warga DWH,

Terimakasih atas bantuan warga DWH selama ini, saat ini saya mengalami kendala terkait proses apache httpd. Hal ini saya tidak tahu apakah ini karena DDOS atau memang ada proses yang salah atau memang memory saya kurang.

NOTE : Saya menggunakan vestacp, dengan httpd dan nginx, serta database mariadb.

1 bulan server berjalan lancar, namun pagi kemarin pukul 6 (kira-kira), memory melonjak drastis. Dari semula load hanya 0.x menjadi hampir 140.x. Dan tentunya webnya berat sekali hingga proses komputasi lambat malah timeout. Hanya saja proses ini hilang-muncul-hilang, setiap beberapa menit sekali (kurang dari 10 menit). Mungkin akan terlihat seperti gelombang,

Untuk lebih jelasnya mungkin berikut ada statistiknya

#interval 1 hari

#Load Usage interval 1 hari

Mungkin dari warga DWH sendiri bisa memberikan solusi terkait permasalahan diatas.

Terimakasih banyak.
 
ada kemungkinan memang ada DOS,
bisa dicoba cek access.log dan error.log pada httpd-nya.

kalau memang benar demikian, bisa dicoba dengan pasang module mod_limitipconn pada httpdnya.

baru denger, tekape dulu
biasanya itu kena dos, mungkin slowloris, cek di access_log biasanya ada IP yang itu ke itu saja yang akses dan requestnya cenderung sama

Udah lama ada, dari 2002.
