Squidview is an interactive console program which monitors and displays squid logs in a nice fashion, and may then go deeper with searching and reporting functions.

(If you don't know what squid is or does this program is probably not for you.)

To use squidview you must at least have read access to squid's access.log file. You may need to see your administrator for this. Squidview uses this text log file for all operations. It does not generate its own database for tasks.

Sphinx is a full-text search engine, distributed under GPL version 2.
Commercial licensing is also available upon request.

Generally, it's a standalone search engine, meant to provide fast,
size-efficient and relevant fulltext search functions to other
applications. Sphinx was specially designed to integrate well with SQL
databases and scripting languages. Currently built-in data source
drivers support fetching data either via direct connection to MySQL,
PostgreSQL, or from a pipe in a custom XML format.

As for the name, Sphinx is an acronym which is officially decoded as
SQL Phrase Index. Yes, I know about CMU's Sphinx project.
