Berikut ini adalah beberapa perintah yang dapat Anda lakukan untuk melihat performansi squid proxy server anda. Perintah ini dapat anda buat dalam bentuk file berextensi ".sh" dan letakkan di direktori /usr/sbin, sehingga anda tidak perlu menghapalkan syntax2 tersebut. Cukup membantu untuk para network administrator atau teknisi.

1. Perintah pertama

squidclient -h localhost -p 8080 mgr:info

Sesuaikan port 8080 dengan port squid Anda.
