I am looking at LTT as a good starting point to recording traces for post-crash analysis. Unlike what most people are doing, I am developing for an embedded system which has no place to store a crash dump. My approach is to write the traces to "reserved" memory that won't be cleared when the system comes back up. To do this, it looks like the approach would be to use flight recorder mode on buffers allocated in the reserved areas. Trying to figure out where to splice into LTT to do this, however, is somewhat time-consuming as there is less documentation in the code than I would prefer. From what I can gather, the LTT code looks designed so that it might accommodate a new transport layer that I could write to do while I want. Is there documentation on LTT buffer allocation outside of the code to which I might refer, or can someone give me a few tips on where to start? Alternatively, is there a better approach that someone can think of? -- David VomLehn, Staff O/S Software Engineer Scientific Atlanta, A Cisco Company 10590 N.
