    Thanks for the article on the SQL log. While the logs are useful for many purposes, more often than ever they are very confusing and overwhelming with the number of records. Would it be possible for you to write few articles to decipher the log in a simple fashion approach, that is for some generic scenario’s like (CPU usage, culprit transaction etc) what kind of message some one should be looking for. I could very well google this and find out but so far the articles I have seen are little bit overwhelming with ton of information and I have come to love your simple, practical fashion approach.

    Thanks much

    Hi Pinaldave,

    Thanks for the info. I was wondering, is there any way to clear the log? (is there a table which I can delete records from?)

    There was a small bug in some software which generated hundred of thousands of the same messages. If I can delete them the log would become more usefull.

    best regards

    Marcel
