The grab everything approach
often
requires quite high data-rate capture for long periods of time, leading to very large storage requirements. This approach is sometimes necessary for company security and testing trace-ability reasons. The other alternative is the smart logging approach,
in which you run an intelligent logging algorithm, maintaining one or more rotating buffers with defined pre-trigger periods. When an event of interest occurs, log the pre- and post-event data and continue. This massively reduces the |

storage needed, though the logger must now be capable of not only capturing, but also analysing the data at the requisite rate. You must also have a high level of confidence that the logging algorithm is correct and will recognise all instances of the event of interest.
