A very simple web crawler and checker

ChkWeb

This is a very simple web crawler to check the public webpages in a webserver.

to use, call the subcommand start with the URL to crawl:

chkweb start http://localhost/

This will create a sqlite3 database pages.db whith the urls being detected by the spyder. It also checks this first page and add all the locals links to the database as pending url to be checked. Now you can run:

chkweb advance

to continue the crawling process. This is going to take at most 10 pending url and repeat the process with each of then. You can define the maximun amount of new urls to be checked setting the environment variable CHKWEB_ADVANCE_LIMIT or setting the --limit command line option, like in this example:

chkweb advance --limit 1000

Checking process status

You can check the current process status with the subcommand status, like this:

chkweb status

Logs

A log file is stored in logs/chklog.log. You can change the log level either in the settings file or declaring a environment variable named CHKWEB_LOG_LEVEL to the desired level. It is set to ERROR by default.
