Monitoring Squid with squidclient

MandailingNatal.com - Monitoring Squid with squidclient - cara Monitoring Squid with squidclient - Kemarin sempat bingung bagaimana melihat byts hit ratio dari squid yang baru ku install, mau install cachti atau mrtg males karena kompnya agak jadul dengan memori yang pas pasan, apalagi bila install mrtg dan cacti harus install webserver dan cgi. Namun hasil dari jalan jalan dan searching di google akhirnya saya tau ada tools kecil dan ringan untuk melihat permformance squid. Tanpa harus repot untuk install mrtg dan cacti.

Dalam squid yang saya gunakan berjalan pada mesin ubuntu server. Dan solusi untuk melihat performance squid dan melihat byts hit ratio pun cukup mudah. Dengan SQUIDCLIENT, jadi solusinya adalah install squidclient di mesin yang kita gunakan.

apt-get install squidclient

tunggu sampai instalasi selesai

dan cara penggunaannya cukup mudah di squid saya saya ketikkan seperti di bawah ini, meskipun masih banyak comment dan perintah dari squidclient ini yang saya tidak tahu

root@ubuntu:~# squidclient 192.168.88.1 -p 9988 mgr:infmaka hasilnya seperti di bawah ini
