Another valuable tool for checking links is Link Quality at a Glance from Hans van der Graaf.Some links such as Basic State and Lemon give a 404 error code or a 405 code in the case of MLab but appear to be accessible and so currently are left in. Increasingly new additions are from reader suggestions/recommendations.Others such as Mind Array and Net Logger sometimes timeout, but usually work. If you have a suggestion for adding something: please send an email to cottrell at slac.making sure that you indicate where the tool fits in the hierarchy, provide a URL to get more information on the tool, and provide a short one sentence description of the tool's purpose with no marketing hyperbole.

Most Linux distributions are equipped with tons of monitoring. It can send alert when things go wrong and again when they get better. FAN goals are to provide a Nagios installation including most tools provided by the Nagios Community.

We welcome corrections such as identifying broken links (especially if you can provide an alternate/update), since over the years companies are absorbed by others, disappear, split up, change their web site etc.

To find broken links, we use Check Link suggested by Brad Canham, and even better the Chrome browser extension for checking links, suggested by Brian Albert Jensen.
