ecmcache logfiles

Hi guys I read on another forum that was discussing how many clients you could have before a freezing occurs and read that there was some kind of cache that is used so if say 5 people were all watching a specifice sports chanel on sly sports then the card would not have to service all 5 clients but the cache would as it would hold the ecms. It was also mentioned that you could look at the log to see how this cache is working. My question is how do I see the logs? apparantly oscam sets this caching up by default on aa standard setup. Do I need to turn summat on to see the logs. Cheers guys
