SETI Monitor is a free add-on for SETI@home. It allows you to monitor the activity of your SETI@home client and see what it finds using virtually no CPU power. SETI Monitor shows the signals found by your SETI@home client and saves information about completed work units. It will also tell you if you find something interesting. You can see the signals found in your current work unit, browse through previous results and see the totals. SETI Monitor is extremely efficient as it uses less than 0.01% of CPU power. While being a powerful tool SETI Monitor is very easy to use. SETI Monitor also features an easy to use work unit caching system for SETI@home. It allows you to download several work units at once, which SETI@home will process one after another without the need to connect to the server. It will then connect, return all the results and get new work units. All you need to do is to set the cache size, and it will start working right away. The cache works with all versions of SETI@home for Windows, including the text and graphic clients.
