I have made good progress with getting the evlog data into a db2 table. In looking through the code in evlview for getting notified of new events, I was puzzled by something. I suspect this is a naive question, but: - The code uses posix_log_notify_add to ask to be notified about new events, but then it uses posix_log_read to process all of the events. To the uninitiated, that seems like a contradiction. Why ask to be notified, if you are essentially going to loop on reading the log for new events anyway? Is it because there is a level of indirection between the evlog event, and this posix log?? Also, I am interested in getting any opinions on the performance expectations of using this notify technique vs. the plug-in technique. Expecting to have a large volume of events over 1,024 nodes, so pathlength is important. thanks!
