Monitoring

I have been using this product for the last few hours and I am satisfied with the results so far!

Powerful command-line packet analyzer.

Great free tool to monitor Laravel applications

Many monitoring and blocking features. Filter search engine results, blocks games, records screenshots and keystrokes.

Great menu monitor originally written by Alex Harper. Was almost abandoned in 2014 but saved by Yuji Tachikawa who maintains it since then with fixes every few months. Multiple forks also add interesting features (see project's README for links).
