We allow 1000 characters in the exception context, if there are more characters they will be removed, as you experience. The use of exception context was intended that you could send a little more inforomation in with exception. It was never meant to be sent an entire log text into Analytics. It is not currently possible to increase the length of text messages.
If you want to collect the whole logs or longer texts, I recommend you to take a look at Teleriks EverLive (www.telerik.com/everlive) where you can store the entire logfile, it is a storage in the cloud.
